How much can I save by buying an AC in the off-season in London Ontario?

London Ontario homeowners who replace their AC in the off-season (February through April or September through November) typically save $300 to $800 compared to emergency summer replacement. The savings come from better equipment availability, more flexible scheduling, and the absence of peak-season surcharges. If your AC qualifies for the Enbridge Home Efficiency Rebate or Canada Greener Homes Grant, you can save an additional $1,500 to $6,500.

Is spring or fall better for AC installation in London Ontario?

Spring (February through April) is generally better than fall for AC installation in London Ontario. Installing in spring means your new unit is tested and running before the first heat wave — you are not discovering installation issues on a 34°C July afternoon. Fall installation works well if you missed spring, but you will not confirm the cooling performance until the following summer.

What AC brands does Hawana install in London Ontario?

Hawana installs all major AC brands in London Ontario including Lennox, Carrier, Trane, Goodman, Rheem, American Standard, Bryant, York, and Napoleon. For rebate-eligible installations, Hawana recommends models that appear on the NRCan qualifying products list or meet Enbridge efficiency requirements. Equipment recommendations are made at the quote stage based on your home's specific needs.

How do I know if my AC needs to be replaced rather than repaired?

Replace rather than repair your AC if: the unit is over 15 years old and requires a repair costing more than 50% of replacement value, the compressor has failed (compressor replacement on an old unit rarely makes financial sense), the system uses R-22 refrigerant (phased out in Canada — parts are scarce and expensive), or the unit has required multiple repairs in the past two years. Hawana provides an honest assessment at the diagnostic visit — we recommend repair when it makes financial sense.

My AC turns on but isn't cooling. What's wrong?

An AC that runs but doesn't cool adequately is usually caused by low refrigerant from a leak (most common), a dirty condenser coil clogged with cottonwood, a frozen evaporator coil, or extreme heat exceeding system capacity. If the outdoor unit is running and air from vents is warm, call a TSSA certified technician.

My AC won't turn on at all. What should I check first?

Check in order: (1) Thermostat — set to COOL, set temp below room temp? (2) Breaker panel — AC breaker tripped? Reset once, fully OFF then ON. (3) Outdoor disconnect — in ON position? (4) If all check out and AC still won't start, call Hawana at (647) 550-4220.

Why does my AC keep tripping the breaker in London Ontario?

A repeatedly tripping AC breaker signals an electrical fault — do not keep resetting it. Common causes: failing compressor drawing too much amperage, wiring short, or failing capacitor causing hard-starts. Call a TSSA certified technician to find the root cause.

Why is there ice on my AC in London Ontario?

Ice on AC lines means: turn AC OFF, set fan to ON, wait 2-3 hours to fully thaw. Most common causes are a severely clogged filter (DIY fix) or low refrigerant (requires TSSA technician). Replace the filter before restarting. If it ices again after a fresh filter, the refrigerant charge needs professional inspection.

How much does AC repair cost in London Ontario in 2026?

Common AC repair costs in London Ontario 2026: capacitor $150-$250, contactor $150-$250, refrigerant leak repair $250-$600, condensate drain clearing $100-$150, condenser coil cleaning $150-$250, compressor $800-$2,000. Hawana provides a written quote before any work. Plan members get 15% off. Call (647) 550-4220.

How quickly can Hawana repair my AC in London Ontario?

Same-day AC repair is available in London Ontario when you call before noon. Hawana does not charge overtime for evenings or weekends — the rate is the same regardless of when you call.

Should I repair or replace my AC in London Ontario?

If your AC is under 8 years old, repair unless cost exceeds 50% of a new system. If 10-14 years old, compare repair cost to new system efficiency gains. If over 15 years old, replacement is usually the better investment — a new 18 SEER2 unit uses 20-30% less electricity. Hawana provides honest guidance at every diagnosis.

How much can I save by buying an AC in the off-season in London Ontario?

London Ontario homeowners who replace their AC in the off-season (February through April or September through November) typically save $300 to $800 compared to emergency summer replacement. The savings come from better equipment availability, more flexible scheduling, and the absence of peak-season surcharges. If your AC qualifies for the Enbridge Home Efficiency Rebate or Canada Greener Homes Grant, you can save an additional $1,500 to $6,500.

Is spring or fall better for AC installation in London Ontario?

Spring (February through April) is generally better than fall for AC installation in London Ontario. Installing in spring means your new unit is tested and running before the first heat wave — you are not discovering installation issues on a 34°C July afternoon. Fall installation works well if you missed spring, but you will not confirm the cooling performance until the following summer.

How do I know if my AC needs to be replaced rather than repaired?

Replace rather than repair your AC if: the unit is over 15 years old and requires a repair costing more than 50% of replacement value, the compressor has failed (compressor replacement on an old unit rarely makes financial sense), the system uses R-22 refrigerant (phased out in Canada — parts are scarce and expensive), or the unit has required multiple repairs in the past two years. Hawana provides an honest assessment at the diagnostic visit — we recommend repair when it makes financial sense.

What is included in the AC installation cost in London Ontario?

A complete AC installation quote should include: outdoor condenser unit (brand and model specified), indoor evaporator coil, refrigerant line set, electrical disconnect box and wiring, City of London permits, refrigerant charge and commissioning, and removal of old unit. Always get a written itemized quote.

What factors affect AC installation cost in London Ontario?

Main factors: home size (larger homes need larger units), SEER2 efficiency rating (higher costs more upfront), brand (Lennox and Carrier cost more than Goodman at same SEER), installation complexity (long line set runs, electrical panel upgrades), and whether the furnace is also being replaced (combo saves on labour).

How much does ductless mini-split installation cost in London Ontario?

Single-zone ductless mini-split installation costs $2,500 to $3,500 in London Ontario. Dual-zone systems cost $3,500 to $5,500. Multi-zone (3-4 rooms) costs $5,000 to $8,000. Cold-climate heat pump mini-splits may qualify for Canada Greener Homes grants of up to $5,000.

Should I replace my furnace at the same time as my AC in London Ontario?

If your furnace is over 12 to 15 years old, replacing both at the same time saves on labour, ensures matched efficiency, and qualifies for Enbridge rebates on the furnace. Hawana provides an honest assessment at the free estimate visit.

Is it cheaper to install AC in spring or summer in London Ontario?

Spring installation (April-May) offers better scheduling availability. Hawana does not charge different prices by season, but spring booking means you get the appointment time you want and can get the system installed before the first hot day arrives.

How much more expensive is a high-efficiency AC in London Ontario?

A 16 SEER2 unit typically costs $3,800 to $4,800 installed. An 18 SEER2 unit costs $4,500 to $5,500. A 20+ SEER2 variable-speed unit costs $5,500 to $6,500. The premium for 20 SEER2 vs 16 SEER2 is roughly $1,500 to $2,000, which pays back in 5 to 8 years in London Ontario.

When should I schedule my spring AC tune-up in London, ON?

The best time for spring AC maintenance is April or early May — before the first heat wave hits. Scheduling early ensures you beat the summer rush and have a technician available when you need one. By late May, most HVAC companies are booked solid for weeks. Book your spring AC tune-up now to avoid the wait.

How much does a spring AC tune-up cost in London, ON?

Our Basic Maintenance Plan is $149/year and includes a complete AC tune-up. A one-time AC tune-up without a plan is $175. Considering that a single emergency repair during a heat wave can cost $500-$1,500, the tune-up pays for itself. Plus, a well-maintained AC saves 15% on cooling costs — $60-$90/year for the average London home.

What's included in a professional AC tune-up?

Our professional AC tune-up includes: inspect and clean condenser coils; check refrigerant levels and adjust; inspect electrical connections and tighten; test capacitors and contactors; clean evaporator coil; check condensate drain line; lubricate moving parts; test thermostat calibration; measure airflow and temperature differential; and provide a written service report. The full inspection takes 45-60 minutes.

Can I do AC maintenance myself or do I need a professional?

You can safely do DIY tasks: change your air filter monthly; clear debris from around the outdoor unit; rinse condenser coils with a garden hose (gentle spray); and check the condensate drain for visible blockages. However, professional maintenance requires specialized tools for: refrigerant level measurement, electrical testing, capacitor checking, deep coil cleaning, and safety control verification. DIY on refrigerant or electrical components is dangerous and voids warranties.

How often should I change my AC air filter?

Change your air filter every 1-3 months depending on usage. In homes with pets, smokers, allergy sufferers, or during peak cooling season (June-August), change monthly. A clean filter improves efficiency by 5-15%, prevents system breakdowns (frozen coils), and improves indoor air quality. A clogged filter is the #1 cause of AC failure.

How much can I save with regular AC maintenance?

A well-maintained AC runs 15% more efficiently, saving $60-$90 annually on cooling costs for the average London home. Regular maintenance also prevents costly emergency repairs ($500-$1,500), extends equipment lifespan by 3-5 years, and maintains manufacturer warranty validity. The $149 tune-up pays for itself in energy savings within 2 years.

Does my new AC need maintenance in its first year?

Yes. Most manufacturers require proof of annual maintenance to keep the warranty valid. Skipping the first year's tune-up could void your warranty. The first year is also critical to verify proper refrigerant charge, check for installation issues, and ensure optimal performance. We provide documentation after every tune-up for warranty compliance.

What are signs my AC needs maintenance before summer?

Signs your AC needs maintenance: weak airflow from vents; unusual noises (grinding, squealing, banging); ice forming on refrigerant lines; water leaking near indoor unit; rising energy bills without increased usage; system running constantly without shutting off; or warm air blowing from vents. Don't wait for a breakdown — schedule maintenance as soon as you notice any warning signs.

What is the best temperature to set my AC for summer savings?

Set your thermostat to 24-26°C (75-78°F) when you're home and awake. Each degree lower increases cooling costs by 3-5%. When away, set to 28°C (82°F) or use a smart thermostat's away mode. A smart thermostat can save 10-15% on cooling costs by automatically adjusting temperatures based on your schedule.

What size AC do I need for my London home?

AC size is measured in tons. A 1,500-2,000 sq ft home typically needs 2-3 tons. Proper sizing requires a professional load calculation (Manual J) considering square footage, insulation, windows, sun exposure, and occupancy. Never guess — an incorrectly sized AC wastes energy, short-cycles, fails prematurely, and won't keep you comfortable. We include a free load calculation with every quote.

Why is my AC running but not cooling my house?

The most common causes are: a dirty air filter restricting airflow; low refrigerant from a leak; a frozen evaporator coil; a failed capacitor or contactor; or a dirty condenser coil. Start by checking your air filter and outdoor unit for debris. If those are clean, call a TSSA-certified technician for diagnosis.

How much does AC repair cost in London, ON?

Our diagnostic fee is $175, which is waived if you proceed with the repair. Common repairs: capacitor replacement $150-$350; contactor replacement $150-$300; refrigerant leak repair $200-$600; coil cleaning $150-$300. We provide upfront pricing before any work begins — no surprises.

Can a dirty air filter cause my AC to stop cooling?

Yes. A severely clogged air filter restricts airflow across the evaporator coil, causing it to freeze. Once frozen, air cannot pass through, and your AC will blow warm air. Change your filter every 1-3 months. This simple fix solves 30% of no-cooling service calls.

How do I know if my AC has a refrigerant leak?

Signs include: AC running constantly but not cooling; ice forming on refrigerant lines; hissing or bubbling sounds from the unit; higher than normal energy bills; and warm air from vents. If you suspect a leak, call a professional immediately — DIY refrigerant handling is illegal and dangerous.

Why is there ice on my AC refrigerant lines?

Ice formation indicates restricted airflow (clogged filter, dirty coils, blocked vents) or low refrigerant. Turn off your AC immediately and run the fan only to thaw the ice. Once thawed, check your filter. If the filter is clean, call a technician — running a frozen AC can damage the compressor ($1,500-$2,500 replacement).

How often should I service my AC in London, ON?

Once per year, ideally in spring (April-May) before cooling season begins. Annual maintenance improves efficiency by 15%, prevents 90% of emergency breakdowns, and maintains manufacturer warranty validity. Our Basic Maintenance Plan is $149/year and includes a complete AC tune-up.

What should I do if my AC stops working on a hot day?

First, check your thermostat (set to cool, temperature below room temp). Check your circuit breaker for a tripped switch. Check your air filter. Check the outdoor unit for debris. If none of these work, call our 24/7 emergency line at (647) 550-4220 — we have zero after-hours surcharge.

Is it worth repairing an old AC or should I replace it?

Apply the 5,000 Rule: multiply your AC's age by the repair cost. If the total exceeds $5,000, replacement is better. For a 12-year-old AC with a $400 repair: $400 x 12 = $4,800 — repair. For a 15-year-old AC with a $600 repair: $600 x 15 = $9,000 — replace. New AC starts at $3,500 installed.

Why is my outside AC unit not turning on?

Most common causes: a tripped circuit breaker; a failed run capacitor ($150-$350 repair); a failed contactor ($150-$300); a faulty thermostat; or a blown fuse. Check your breaker first. If it's not tripped, call a technician — capacitor and contactor issues require professional diagnosis.

What size AC do I need for my London home?

AC size is measured in tons. A 1,500-2,000 sq ft home typically needs 2-3 tons. Proper sizing requires a professional load calculation (Manual J) considering square footage, insulation, windows, and sun exposure. Never guess — an incorrectly sized AC wastes energy, short-cycles, and fails prematurely. We include a free load calculation with every quote.

Is R-410A banned in Canada in 2026?

No. R-410A is not banned in Canada in 2026. Production and import are being phased down gradually, but the refrigerant itself remains legal for service and repairs. New equipment can still be manufactured with R-410A, though manufacturers are transitioning to newer refrigerants over the next several years. Your existing R-410A system will continue to work normally and can be serviced for many years. The R-22 phase-out (which began in 2010) took over a decade to fully impact homeowners — R-410A will follow a similar timeline.

Will my R-410A air conditioner become obsolete?

No. Your R-410A system will continue to work normally. Service and repairs will be available for many years — likely 10-15 years or more. The R-22 phase-out (which began in 2010) took over a decade to fully impact homeowners. R-410A will follow a similar long timeline. There is no reason to replace a working R-410A system because of the 2026 refrigerant changes. Call (647) 550-4220 if you have specific concerns about your system's age or condition.

Should I replace my working R-410A system now?

No. If your system is working properly, there is no reason to replace it because of refrigerant changes. R-410A will be serviceable for years. Replace when your system reaches the end of its natural life (10-15 years) or when repair costs become uneconomical — typically when repair exceeds 50% of replacement cost. At Hawana, we follow the 50% rule: if a repair costs more than half of a new system, we recommend replacement. Otherwise, we repair. Call (647) 550-4220 for honest advice on your specific situation.

What refrigerant should I choose for a new AC or heat pump?

Both R-410A and R-32/R-454B are valid choices in 2026. R-410A is proven, widely supported, and cost-effective. R-32 and R-454B offer lower GWP (Global Warming Potential) and may be slightly more efficient. At Hawana, we install and service all three. We'll help you choose based on your budget, future plans, and manufacturer availability. Call (647) 550-4220 for a free consultation. Rebates are available for all qualifying systems regardless of refrigerant.

AC Buying Guide — London Ontario · Updated April 2026

Best Time to Buy a New AC in London Ontario 2026

When you buy matters as much as what you buy. London Ontario homeowners who time their AC purchase correctly save $300–$800 on installation and avoid the summer scramble when every HVAC company in the city is booked solid. Here is the honest guide from the technicians who install them.

Abdullah Ghzail — TSSA Certified Gas Technician & Founder Hawana HVAC Solutions · London Ontario · April 18, 2026

✓ The Short Answer

The best time to buy a new AC in London Ontario is February through April — the off-season before the cooling rush. Installer schedules are open, equipment is available, prices are at their seasonal low, and your new unit is tested and running before the first heat wave. The second-best window is September through November after summer ends. Avoid June through August if at all possible — that is when you pay the most and wait the longest.

Why Off-Season AC Pricing Is Lower in London Ontario

London Ontario has a strongly seasonal HVAC market. From mid-June through August, every AC installer in the city is operating at or near full capacity — emergency calls from broken AC units fill the schedule, and planned replacement jobs get pushed back weeks. When demand spikes and supply of installer time is fixed, prices reflect it.

In February and March, the reverse is true. Emergency AC calls are almost zero. Technicians have open schedules. Equipment distributors are sitting on winter inventory that they want to move. This is when the market genuinely favours the buyer — and it's when Hawana can schedule installations within days rather than weeks.

💡 Pro Tip: Lock In Your Quote in February, Schedule in April

Get your free in-home quote in February or March. You can lock in the quoted price and schedule installation for April or early May — after the heating season but before the June cooling rush. This gives you the off-season price and the ideal install window in one move.

Spring vs Fall Installation — Which Is Better for London Ontario?

Both the spring window (February through April) and the fall window (September through November) offer similar pricing advantages over summer. The difference is practical:

Factor	Spring Install (Feb–Apr)	Fall Install (Sep–Nov)
Pricing vs summer	✓ Off-season rate	✓ Off-season rate
Scheduling availability	✓ Excellent	✓ Excellent
Test before first heat wave	✓ Yes — tested in spring	✗ Not until next summer
Discover installation issues early	✓ Before summer	✗ Next June
Equipment availability	✓ Full inventory	~ Good, post-summer inventory
Installation conditions	✓ Ideal outdoor temps	✓ Ideal outdoor temps
Rebate processing timing	✓ Received before summer	~ Received in winter

Spring wins on all the factors that matter most — primarily that your new unit is fully tested and any issues resolved before you need it in a heat wave. A fall installation means discovering any deficiency the following June when the unit first runs under load — exactly the worst time.

The Cost of Emergency Summer Replacement

When a London Ontario homeowner's AC fails on a 35°C July afternoon, a few things happen simultaneously: every HVAC company in the city gets a surge of similar calls, equipment that was in stock the previous week is now backordered, and the installer who could have been there in two days is now booked three weeks out.

Emergency AC replacement in July or August in London Ontario typically costs $300–$800 more than the same installation in April — and that is before accounting for the days or weeks you spend without cooling while waiting for a slot. For households with young children, elderly residents, or pets, that waiting period is a genuine hardship.

⚠️ If Your AC Is Over 15 Years Old — Don't Gamble on Another Summer

The odds of a 15-year-old AC unit surviving a full London Ontario summer without failure are not in your favour. A proactive spring replacement costs significantly less than an emergency July replacement — and gives you time to choose the right unit for your home rather than taking whatever is available.

How to Get the Best Price on AC Installation in London Ontario

Book your quote in February or March

Call Hawana in February or March for a free in-home AC quote. Off-season scheduling means the technician can spend more time with you, assess your ductwork and electrical properly, and recommend equipment sized correctly for your home — not just what's on the truck.

Ask about rebate-eligible equipment

Qualifying cold-climate heat pumps and high-efficiency AC units may be eligible for the Enbridge Home Efficiency Rebate (up to $1,500) or Canada Greener Homes Grant (up to $5,000 for heat pumps). Hawana confirms eligibility at the quote stage. If you need to start the Greener Homes process, a registered energy advisor must complete a pre-installation audit first — see our HVAC Rebates Ontario 2026 guide for the full process.

Schedule installation for April or early May

Book installation in April or early May — after the heating season but before the June rush. You get off-season pricing, open scheduling, and your new unit is fully commissioned and tested before the first heat wave. Any installation issues are discovered and resolved while you still have time.

Consider the total cost, not just the purchase price

A higher-efficiency unit (SEER2 18+ vs SEER2 14) costs more upfront but saves $100–$200 per cooling season in electricity over 15+ years. Factor in operating costs, rebate eligibility, and the cost of the next repair on your aging unit when making the repair-vs-replace decision. Hawana provides honest guidance on this at every quote — we never push replacement unnecessarily.

What Does AC Installation Cost in London Ontario in 2026?

Installed cost for a central AC system in London Ontario in 2026 depends primarily on the efficiency rating (SEER2), brand, and your existing ductwork condition. Here is the honest range:

Equipment Type	Installed Cost (CAD)	Enbridge Rebate Eligible	Greener Homes Eligible
Standard central AC (SEER2 14–15)	$3,200–$4,200	Some models	✗ Typically not
High-efficiency AC (SEER2 16–18)	$4,000–$5,500	✓ Eligible models	Some models
Cold-climate heat pump (replaces AC + furnace)	$5,500–$12,000	✓ Up to $1,500	✓ Up to $5,000
Ductless mini-split (1 zone)	$2,800–$4,500	✓ Some models	Some models

All prices in CAD including equipment, installation, permits, and HST. Exact price determined after free in-home assessment. Rebate amounts are approximate and subject to program changes.

🌟 Should You Get a Heat Pump Instead of AC?

If your furnace is also aging, a cold-climate heat pump replaces both your AC and your furnace in one installation. With Enbridge and Greener Homes rebates combined (up to $6,500), the net cost can be comparable to replacing just the AC with a high-efficiency unit — but you get year-round heating and cooling from one system. Worth asking about at your quote.

How to Know If You Should Repair or Replace Your AC

This is the most common question Hawana gets in May and June: the AC is struggling, a technician diagnosed a repair — should you fix it or replace it? The honest framework:

Replace if: the unit is over 15 years old and the repair costs more than 50% of replacement value
Replace if: the compressor has failed on a unit over 10 years old — compressor replacement on an aging system rarely makes financial sense
Replace if: the system uses R-22 refrigerant (phased out in Canada) — parts are scarce and expensive, and the unit will only get harder to service
Replace if: the unit has required multiple repairs in the past two seasons — you are in the reliability failure zone
Repair if: the unit is under 10 years old and the repair is a straightforward component (capacitor, contactor, fan motor) costing under $400
Repair if: the unit is 10–15 years old and the repair is minor — but get a full condition assessment and plan the replacement proactively for next spring

Hawana provides an honest repair-vs-replace assessment on every diagnostic call. We recommend repair when it makes financial sense — we never push replacement to generate a larger sale.

8 Common Causes

Why Your AC Stopped Working — Ranked by Frequency in London Ontario

Failed Run Capacitor — Most Common AC Failure in London Ontario

Very Common — ~35% of AC service calls

🔊 Humming from outdoor unit🔄 Fan not spinning🚫 Unit tries to start, then shuts off⚡ Breaker trips on startup

The run capacitor provides the voltage jolt needed to start and keep the compressor and fan motor running. It degrades over time — London Ontario’s hot summers accelerate this degradation. A failing capacitor starts losing capacity before it fails completely, meaning your system may work some days but struggle on hot days. A fully failed capacitor means the outdoor unit will hum but the fan won’t spin and the compressor won’t start.

Why it happens in London Ontario specifically: Summer heat above 30°C stresses capacitors harder than mild climates. Units in direct afternoon sun are most vulnerable. A capacitor that tests at the low end of spec in April may fail completely in August when ambient temperatures around the unit hit 40°C+.

⚠ Requires Professional Repair

Capacitors store lethal voltage even when the unit is off. Do not open the electrical panel of the outdoor unit. Call Hawana at (647) 550-4220 — capacitor replacement typically takes 30–45 minutes on a service call.

Repair cost:$150–$250(part + labour, same-visit repair)

Tripped Breaker or Blown Fuse

Common

🚫 AC completely dead🔴 Breaker in middle position🔄 Breaker keeps tripping after reset

Your AC’s 240V circuit has a dedicated double-pole breaker in your electrical panel, typically rated 30–50 amps. When the AC draws more current than the breaker rating — due to a starting fault, a failing compressor, or a genuine overload — the breaker trips. There is also an outdoor disconnect box near the outdoor unit. If a fuse blew or the switch was left off, the outdoor unit won’t start while the indoor blower runs normally.

✓ Try This First (DIY)

Go to your electrical panel, find the AC breaker, turn it fully OFF then fully ON. Check the outdoor disconnect — remove the pullout block and inspect the fuses. Replace only if blown. Important: if the breaker trips again immediately or within minutes, stop resetting it and call Hawana — repeated tripping indicates an underlying electrical fault.

DIY cost:$0 (reset) or $15–$30 (replacement fuse)

If repeatedly tripping:$200–$800

Clogged Air Filter — Frozen Evaporator Coil

Common

🌄 Weak airflow from vents🥶 Ice on refrigerant lines💦 Water dripping from air handler

When your air filter becomes severely clogged, airflow across the evaporator coil drops dramatically. The coil becomes too cold without sufficient warm air moving over it, and the moisture in the air freezes on the coil surface. A frozen coil cannot transfer heat — cooling stops entirely. London Ontario cottonwood season (May–June) can clog a 1-inch filter in 2–3 weeks during peak seed release.

✓ DIY Fix — Do This Now

Turn the AC OFF at the thermostat. Set the fan to ON (just the fan, not cool). This blows warm air over the frozen coil to thaw it. Wait 2–3 hours. Replace the filter. Restart in COOL mode. If it ices up again within 24–48 hours after a fresh filter, the cause is low refrigerant — call Hawana.

DIY cost:$10–$25 (replacement filter)

If refrigerant is cause:$250–$600

Low Refrigerant from a Leak

Common

🌡 AC runs but blows lukewarm air🥶 Ice on refrigerant lines (sometimes)⌛ Runs constantly, house won’t cool

Refrigerant is the substance that absorbs heat from inside your home and releases it outside. It circulates in a closed loop and does not get used up — it only leaves the system if there is a leak. A slow refrigerant leak causes the system to gradually lose cooling capacity over weeks or months.

Important: Adding refrigerant without finding and repairing the leak is a bandaid that lasts one season. The leak continues, refrigerant levels drop again next year. A proper repair finds the leak, repairs it, and recharges to manufacturer specification.

⚠ Requires TSSA Certified Technician

Refrigerant handling is regulated under TSSA certification. Call Hawana at (647) 550-4220. We locate the leak using electronic leak detection, repair the leak, pressure-test the system, then recharge to exact manufacturer specification.

Repair cost:$250–$600(leak detection + repair + recharge)

Failed Contactor

Moderately Common

🚫 Outdoor unit won’t start at all🔊 Clicking from outdoor unit

The contactor is an electrical relay switch that connects the high-voltage power supply to the compressor and fan motor when the thermostat calls for cooling. Over time, the contact points develop pits and burning from repeated arcing — eventually the contacts no longer make a solid connection and the outdoor unit won’t start. A failing contactor may cause the outdoor unit to start intermittently before failing completely.

⚠ Requires Professional Repair

Contactor replacement is a quick repair (30–45 minutes) but involves working with 240V live circuits. Call Hawana — it is a routine same-visit repair in almost all cases.

Repair cost:$150–$250

Blocked Condensate Drain Line

Moderately Common

💦 Water pooling near air handler🚫 AC shuts off unexpectedly😃 AC cycles on briefly then shuts off

As your AC cools the air, it removes moisture that drips off the evaporator coil into a drain pan and flows out through a condensate drain line. London Ontario’s moderately hard water deposits calcium and algae in this line over time. When it blocks completely, the drain pan fills and triggers a safety float switch that shuts the AC off entirely.

✓ Sometimes DIY

Locate the white PVC drain line from the air handler. Some systems have a cleanout cap where you can pour a cup of diluted white vinegar to clear algae buildup. If you can’t safely access the line, call Hawana — drain clearing is a quick service-visit fix.

Professional clearing:$100–$150

Dirty Condenser Coil — London Ontario Cottonwood Problem

Common May–July in London Ontario

⇧ AC runs constantly but house doesn’t cool🌡 Outdoor unit very hot to the touch🌮 Visible debris on outdoor unit fins

The outdoor condenser unit rejects heat by blowing air through the condenser coil. When the coil fins are packed with cottonwood seeds, grass clippings, or general debris, airflow is severely restricted. The system cannot reject heat efficiently — it runs longer, works harder, uses more electricity, and may overheat and lock out. London Ontario cottonwood trees release seeds in May through early July that can pack the condenser fins within 2–3 weeks.

✓ Partial DIY — Gentle Rinse

Turn the outdoor unit off at the disconnect box. Using a garden hose (low pressure, no pressure washer), rinse from top to bottom through the fins. For deeply impacted coils, professional coil cleaning with coil cleaner solution is more effective.

Professional coil cleaning:$150–$250(included in annual tune-up)

Failed Compressor

Less Common — but Expensive

🚫 Outdoor unit won’t start despite good capacitor🔊 Loud grinding or clanking📅 System is 10+ years old

The compressor is the heart of your AC system. Compressor failure is the most expensive AC repair and usually happens in systems that are 10–15+ years old, have had chronic refrigerant issues, or have been running with improper refrigerant charge over many seasons.

Repair vs replace decision: A compressor replacement costs $800–$2,000. On a system over 12 years old, this repair cost is often better invested in a new system that is more efficient, under full warranty, and won’t need another major repair in 2–3 years. Hawana provides honest guidance at every diagnosis.

⚠ Always Requires Professional Diagnosis

Compressor failure must be confirmed by a technician — several other causes produce identical symptoms. Call Hawana at (647) 550-4220 for same-day diagnosis.

Repair cost:$800–$2,000

Replacement AC:$3,500–$6,500(often better value on 12+ yr systems)

Step-by-Step Diagnosis

How to Diagnose Your AC Problem in London Ontario — In Order

Follow these steps in sequence before calling. Many AC failures are resolved in steps 1–3.

Check the Thermostat

Set to COOL mode. Set point at least 3°C below current room temperature. Fan set to AUTO. If it has batteries, replace them. A surprising number of service calls end here.

Check the Air Filter

Pull out the filter from your furnace or air handler. Hold it to the light. If you cannot see light through it, replace it immediately. If ice is visible on the refrigerant lines, turn AC OFF, fan ON, wait 2–3 hours for the ice to melt before restarting.

Check the Electrical Panel

Open your electrical panel. Find the AC breaker — a double-pole breaker rated 30–50A. If it is in the middle position (tripped), turn it fully OFF then fully ON. Do this once only. Also check the outdoor disconnect box — make sure it is in the ON position.

Check the Outdoor Unit

Go outside and observe the outdoor condenser unit when the system is calling for cooling. Is the fan spinning? Is the unit running? A running outdoor unit with warm air from vents = refrigerant issue. A silent outdoor unit with indoor blower running = capacitor, contactor, or electrical issue.

Call Hawana if the Above Steps Don’t Resolve It

If your AC still won’t run or won’t cool after steps 1–4, call Hawana HVAC at (647) 550-4220. Tell the technician what you observed in each step above — this helps diagnose faster and arrive with the right parts. Same-day repair available. No overtime charges.

Abdullah Ghzail — TSSA Certified Technician & Founder

“In London Ontario, the capacitor and the air filter account for the majority of the AC service calls I respond to every summer. The capacitor is a $15 part that costs $150–$250 installed — it’s entirely preventable with an annual tune-up that tests it before it fails. The clogged filter is completely free to prevent with a $15 filter replacement every month during cooling season. The two most common and most expensive emergency calls are also the two most preventable.”

Central AC $3,500–$6,500 · Ductless mini-split from $2,500 · Combo $6,500–$10,000. What affects your price. What to watch out for. How to get an accurate quote.

📅 April 2026 👤 Abdullah Ghzail, TSSA Certified Technician ⌛ 8 min read

If you’re researching a new AC for your London Ontario home, one thing is frustrating immediately: most HVAC companies don’t publish their prices. You call, they send someone out, and suddenly you’re comparing quotes you don’t fully understand. This guide changes that. We’re publishing the real 2026 numbers — what you should expect to pay, why costs vary, and what to watch out for when comparing quotes.

These prices are based on actual Hawana HVAC installations in London Ontario in 2025–2026. They assume a standard London Ontario home with an existing furnace and ductwork in reasonable condition.

2026 Price Breakdown

AC Installation Costs London Ontario 2026 — All System Types

All prices include equipment, labour, refrigerant line set, and City of London permit.

System Type	Price Range (Installed)	Best For	Notes
Central AC — 14–16 SEER2Good efficiency, lower cost	$3,500–$4,500	Most London Ontario homes with existing ductwork	Goodman, Rheem, Trane entry range
Central AC — 17–18 SEER2Better efficiency — recommended	$4,500–$5,500	Best value for most London Ontario homeowners	Carrier, Lennox, Trane mid range
Central AC — 20+ SEER2Variable speed, premium efficiency	$5,500–$6,500	Large homes, long cooling seasons, efficiency priority	Lennox XC21, Carrier Infinity series
Ductless Mini-Split — Single ZoneNo ductwork needed	$2,500–$3,500	Additions, garages, older homes without ducts	Daikin, Mitsubishi, LG
Ductless Mini-Split — Dual Zone	$3,500–$5,500	Two rooms needing independent temperature control	One outdoor unit, two indoor heads
Ductless Mini-Split — Multi-Zone (3–4 rooms)	$5,000–$8,000	Whole-home zone cooling without ductwork	Cold-climate models may qualify for rebates
AC + Furnace ComboReplace both together	$6,500–$10,000	When furnace is also 12–15+ years old	Saves on labour vs two separate installs

All prices in CAD. Actual pricing depends on your home’s specific situation. Hawana provides a free written estimate after a proper Manual J load calculation.

Cost Factors

What Makes AC Installation Cost More or Less in London Ontario

Two homes with identical square footage can have AC installation costs that differ by $2,000 or more. Here’s why.

🏠

Home Size and Layout

A 1,000 sq ft London Ontario home needs roughly a 1.5–2 ton unit ($3,500–$4,000 installed). A 2,500 sq ft home needs 3–3.5 tons ($4,500–$5,500). Larger equipment costs more. But sizing is not just about square footage — ceiling height, insulation quality, window area, and sun exposure all affect the correct size. An honest HVAC company always does a Manual J load calculation. Anyone who quotes based on square footage alone should be questioned.

⭐

Efficiency Rating (SEER2)

SEER2 (Seasonal Energy Efficiency Ratio) measures cooling efficiency. The minimum legal requirement in Ontario is 14 SEER2. Every step up in efficiency adds roughly $500–$1,000 to installation cost but reduces annual operating costs. See the SEER comparison below for the London Ontario payback calculation.

📏

Refrigerant Line Set Length and Difficulty

Standard central AC installation includes a line set run of 15–25 feet. Homes where the outdoor unit must be placed further from the air handler require longer line sets at $20–$30 per foot. Difficult routing through walls, attics, or crawl spaces adds 1–3 hours of labour.

⚡

Electrical Panel Capacity

Modern high-efficiency AC units require a dedicated 240V circuit. Many older London Ontario homes (Old South, Old North, Westmount, East London) have 100A panels that may not have capacity for a new AC circuit without a panel upgrade. An electrical panel upgrade adds $1,500–$3,000 to the project cost. A reputable installer assesses this upfront and includes it in the written quote.

🏷

Brand Selection

A 16 SEER2 Goodman typically costs $500–$1,000 less than a 16 SEER2 Carrier or Lennox at the same efficiency rating. The premium brands offer longer warranties, quieter operation, and parts availability advantages. For most London Ontario homeowners, mid-range brands (Carrier, Trane, Rheem) offer the best combination of price, quality, and parts availability.

🔄

Replacing Furnace at the Same Time

If your furnace is also approaching end of life (12–15+ years), replacing both in one installation visit saves $500–$800 in labour compared to two separate visits. Both systems are also properly matched for efficiency. The combined cost ($6,500–$10,000) is significantly less than two separate installations total.

SEER2 Comparison

Which SEER Rating Is Worth It for London Ontario?

Higher SEER2 costs more upfront but saves on electricity. Here’s the London Ontario payback calculation.

14 SEER2

$3,500–$4,200Minimum legal. Good for low cooling-use homes or tight budgets.

16 SEER2

$3,800–$4,800~12% more efficient than 14 SEER. Payback vs 14 SEER: ~5 years in London ON.

18 SEER2 ⭐ Recommended

$4,500–$5,500Best balance of cost and savings for most London Ontario homes. ~7 yr payback vs 14 SEER.

20+ SEER2

$5,500–$6,500Variable speed. Quietest, most efficient. Best payback in larger London homes.

Payback estimates based on London Ontario average summer (120 cooling days), average Hydro One rate of $0.15/kWh, and a 2,000 sq ft home. Your results will vary. Hawana discusses expected operating costs at the free estimate visit.

🌿

Canada Greener Homes Grants — Up to $5,000 for Qualifying Systems

Cold-climate heat pump systems (which replace both your furnace and AC) qualify for Canada Greener Homes grants of up to $5,000. A pre-installation energy audit by a registered energy advisor is required before purchasing. Hawana installs qualifying equipment and provides documentation for the application.

“The biggest mistake I see London Ontario homeowners make is choosing the cheapest quote without understanding what’s included. An $800 cheaper quote that excludes the permit, charges extra for refrigerant, and skips the load calculation ends up costing more — in money, in comfort, and in system lifespan. My advice: always ask for a written itemized quote with the model number and SEER rating clearly stated. Then compare apples to apples.”

2026 Refrigerant Changes in Ontario: What London Homeowners Need to Know About R-410A Phase-Out

By Abdullah Ghzail — Lead Technician, TSSA Certified

Published: March 13, 2026 | Updated: April 1, 2026

8 min read

You've probably heard about refrigerant changes coming in 2026. Headlines mention "R-410A phase-out" and new refrigerants like R-32 and R-454B. As owner and lead TSSA-certified technician at Hawana HVAC Solutions, I talk to concerned homeowners in London, St. Thomas, Strathroy, Woodstock, and across Southwestern Ontario every week. The good news: R-410A is still fully legal, widely available, and an excellent refrigerant in 2026. Most systems installed today (and many being installed right now) use R-410A, and that will continue for years. Let's break down what's really happening and what it means for your home.

Quick Answer: R-410A is NOT banned in Canada in 2026. You can still repair existing systems, buy new R-410A equipment, and service your AC or heat pump normally. Newer refrigerants like R-32 and R-454B are coming, but there's no rush to replace a working system. Call (647) 550-4220 if you have specific concerns about your system.

The Current Status of R-410A in Ontario – 2026 Reality

R-410A is not banned in Canada or Ontario in 2026. It remains the standard refrigerant for the vast majority of residential air conditioners, heat pumps, and mini-splits being manufactured and installed right now. Here's why homeowners and technicians still trust it:

Proven performance – 20+ years of reliable use in Ontario's cold winters and humid summers
High efficiency – works well with modern high-SEER systems
Plenty of supply – parts, refrigerant, and trained technicians are widely available
Cost-effective repairs – no premium pricing for R-410A components yet

R-410A — Still the Standard

Widely available. Proven in Ontario conditions. Most systems use it. Repairs are straightforward. No need to replace a working system.

✓ Best for most homeowners in 2026

R-32 — Emerging Replacement

Lower GWP (675 vs 2088). Slightly more efficient. Newer — fewer long-term installations in Ontario cold winters. Good option for new builds.

✓ Good for new installations

R-454B — Alternative Option

Very low GWP (466). Similar performance to R-410A. Still new to Canadian market. Technician training ongoing. Available through select manufacturers.

✓ Future-proof option

What Is Actually Changing in 2026?

Canada (following U.S. EPA rules) is gradually reducing production and import of high-GWP (Global Warming Potential) refrigerants like R-410A. This means:

New manufactured equipment will increasingly use lower-GWP refrigerants (R-32, R-454B) starting in 2025–2026
R-410A will still be allowed for service/repairs of existing systems for many years (similar to the R-22 phase-out timeline that took over a decade)
Eventually R-410A will become more expensive and harder to source — but we're not there yet in 2026

Think of it like R-22: When R-22 was phased out starting in 2010, it remained available for repairs for over 10 years. R-410A will follow a similar long transition. Your system will not become obsolete overnight.

Refrigerant Comparison: R-410A vs R-32 vs R-454B

Refrigerant	GWP (Global Warming Potential)	Efficiency	Availability in 2026	Best For
R-410A	2,088	High (baseline)	Widely available	Existing systems, cost-effective repairs
R-32	675	Up to 10% higher	Growing availability	New installations, Mitsubishi/Daikin systems
R-454B	466	Similar to R-410A	Limited (Carrier, Bryant)	Future-proof new systems

Newer Refrigerants: R-32 and R-454B – Where They Stand in 2026

R-32 and R-454B are the main replacements. They have much lower GWP and are slightly more efficient in some conditions. However, in Southwestern Ontario in 2026 they are still relatively new:

Fewer real-world installations compared to R-410A
Limited long-term customer feedback in our cold winters
Technician training is ongoing — not every company is fully experienced yet
Parts availability is good but not as widespread as R-410A

We'll know much more about their long-term reliability in Ontario conditions in the coming years. For now, R-410A remains the safe, proven choice for most homeowners.

What This Means for London Homeowners in 2026

If your current AC or heat pump uses R-410A → You can repair it normally. No need to replace early. Parts and refrigerant are widely available.
If buying new → You can still choose R-410A systems (still widely sold & installed). R-32/R-454B systems are also available if you want to future-proof.
If considering future-proofing → Newer R-32 or R-454B models are good options, but not urgent yet. R-410A will be serviceable for many years.
Rebates remain strong for both – up to $5,000 for qualifying heat pumps regardless of refrigerant choice.

★★★★★

"Was worried about R-410A phase-out. Abdullah explained it's still fine for years. Kept our existing system running perfectly. Saved us the cost of an unnecessary replacement."

Karen L. — Masonville, London

★★★★★

"New R-410A heat pump installed – no issues, great performance. Glad we didn't rush into newer refrigerant. The technician explained both options clearly and let us decide."

Mike R. — White Oaks, London

Abdullah Ghzail — Owner & Lead TSSA-Certified HVAC Specialist

R-410A is still the workhorse in 2026 — reliable, affordable to service, and widely supported. Newer refrigerants like R-32 are promising, but we'll have more real-world data in the years ahead. My team keeps both types running perfectly for London-area homes. If you're worried about your system, call us. We'll give you honest advice — no pressure to replace what's working.

Smart Thermostat Guide for Ontario Homes 2026

Energy savings, installation costs, rebates, and professional advice for London homeowners

Updated March 25, 2026 By Abdullah Ghzail, Lead Technician 7 min read

Smart thermostats have become a must-have upgrade for Ontario homes in 2026 — especially in London where winters are long and summers humid. These devices learn your schedule, adjust temperatures automatically, and save 10–20% on heating/cooling bills. As owner and lead TSSA-certified technician at Hawana HVAC Solutions, I've installed hundreds of these units across London, St. Thomas, Strathroy, Woodstock and beyond. Here's my complete 2026 guide to smart thermostats for Southwestern Ontario homes.

Why Smart Thermostats Are Worth It in London Ontario

Save 10–20% on energy bills — average $150–$300/year in London homes
Remote control via app — adjust from anywhere (great for snow days or vacations)
Geofencing — auto-adjusts when you leave/return home
Integration with Alexa, Google Home, Apple HomeKit
Air quality & occupancy sensors on premium models
Rebates up to $125 from Enbridge & utilities for ENERGY STAR models

Smart Thermostat Comparison 2026
