Common AC Problems in Southwestern Ontario — Causes & Fixes
Southwestern Ontario summers are hot and humid. Here are the most common AC failures, what causes them, and what the repair involves. Every diagnosis starts with a $175 visit. Zero surcharge at any hour.
AC Running But Not Cooling
Most common cause: low refrigerant from a slow leak. The system blows air but the refrigerant is insufficient to absorb heat. Requires professional leak detection, leak repair, and refrigerant recharge. Second common cause: dirty evaporator or condenser coils that insulate the refrigerant from the air.
Leak detection + repair + recharge $250–$600. Coil cleaning during annual maintenance prevents this. R-22 systems — see R-22 note below.
AC Not Turning On
Usually a failed capacitor (the start capacitor gives the compressor and fan motors the jolt to start — it degrades over time and fails without warning), a tripped circuit breaker, a failed contactor (the high-voltage relay that switches the compressor on), or a thermostat/wiring fault.
Capacitor replacement $180–$280. Contactor $150–$250. Circuit breaker — check your panel first before calling. Thermostat wiring $100–$200.
AC Freezing Up — Ice on the Unit
A frozen evaporator coil is almost always caused by restricted airflow: a clogged air filter, blocked return air vents, or a failing blower motor. Low refrigerant can also cause freezing. When frozen, shut the system off (fan only) for 2–4 hours to thaw, then replace the filter and call for service.
Replace filter immediately. If freezing recurs: blower motor test or refrigerant check. Blower motor $300–$500. Refrigerant $250–$600.
AC Humid — House Feels Sticky
Usually means the AC is oversized and short-cycling. An oversized AC cools the temperature quickly but shuts off before running long enough to remove humidity from the air. The result is a house that feels cool but clammy. Also caused by a dirty evaporator coil. Both require professional assessment.
Oversized unit — requires replacement with correctly sized unit (Manual J). Dirty coil — coil cleaning during annual maintenance. This is why correct sizing matters.
AC Making Strange Noises
Squealing or screeching: worn fan belt (older units) or failing fan motor bearing. Banging or clanging: loose component inside the unit — shut off immediately to prevent further damage. Clicking repeatedly at startup: failed capacitor or relay. Hissing: refrigerant leak. All require professional diagnosis.
Depends on source: fan motor $300–$500, capacitor $180–$280, refrigerant leak $250–$600. Banging — shut off and call immediately.
Water Leaking from AC
Condensate water forms on the evaporator coil and drains through the drain line. A blocked drain line (algae growth in Southwestern Ontario's humid summers) causes water to back up and overflow into the home. Also caused by a cracked or disconnected drain pan. Annual drain line flush prevents the majority of these failures.
Drain line flush $75 (included in $149 annual maintenance). Emergency drain line clearing $150–$200. Annual maintenance prevents this.
Should I Repair or Replace My Air Conditioner?
The 50 percent rule: if AC repair cost exceeds $1,750 (50% of $3,500 replacement), replacement is almost always the better investment. Both quotes at the same $175 diagnostic visit. Zero surcharge.
🚨 Replace — These Signals Point to Replacement
- Repair cost exceeds $1,750 (50% of $3,500)
- System is 12 or more years old
- R-22 refrigerant — discontinued in Canada since 2020, cannot be properly recharged
- Compressor failure — cost almost always exceeds 50% of new system
- Two or more repairs in the same cooling season
- House humid despite AC running — oversized system
- Rising electricity bills without usage increase
- Indoor coil corroded or refrigerant leak recurring
- System uses R-22 and has a refrigerant leak
✓ Repair — These Signals Point to Repair
- Repair cost below $1,750
- System is under 10 years old
- R-410A refrigerant — still serviceable (2010 and newer)
- Single component failure — capacitor, contactor, thermostat
- System cools well when working, no recurring pattern
- Still within manufacturer warranty
- No refrigerant leak detected
- Clean indoor coil, no corrosion
R-22 refrigerant note — critical for Ontario homeowners: Any AC system installed before approximately 2010 almost certainly uses R-22. R-22 has not been manufactured in Canada since 2020. Recharging a leaking R-22 system with reclaimed R-22 currently costs $600–$1,200 and does not fix the underlying leak — the refrigerant will continue to leak. At this cost versus a $3,500 new system, replacement is almost always the correct decision. Hawana always provides both a repair quote (including the R-22 recharge cost) and a full replacement quote at the same $175 diagnostic visit. Zero surcharge at any hour. Call (647) 550-4220.

How Much Does a High-Efficiency AC Save in Ontario?
SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an AC uses electricity. Higher SEER = less electricity per unit of cooling. Since 2023, new Ontario installations must be at least 16 SEER. Here is the annual savings for a typical 3-ton London Ontario home running 800 cooling hours per year.
| SEER Rating | Annual Electricity Cost (3-ton, 800 hrs) | Annual Saving vs 13 SEER | 10-Year Saving | Best For |
|---|---|---|---|---|
| 13 SEER (old — pre-2023) | ~$680/yr | — | — | Baseline only — no longer installed |
| 16 SEER (2026 minimum) | ~$553/yr | $127/yr | $1,270 | Goodman from $3,500 — strong value |
| 18 SEER | ~$489/yr | $191/yr | $1,910 | Mid-efficiency Lennox / Carrier |
| 20 SEER | ~$442/yr | $238/yr | $2,380 | Lennox XC21 / Carrier Infinity 21 |
| Heat pump (20+ SEER + heating) | ~$442/yr cooling + heating savings | $238/yr cooling + gas savings | $2,380+ cooling + heating | Best total ROI when furnace also needs replacing |
Ontario electricity rate note: Calculations use approximately $0.17/kWh — Ontario's residential rate. A 3-ton (36,000 BTU) AC running 800 hours per year at 13 SEER consumes approximately 4,000 kWh. At 16 SEER it consumes approximately 3,253 kWh. The difference of 747 kWh at $0.17 = $127/yr. The right SEER choice depends on your annual cooling hours. London Ontario typically runs 750–850 cooling hours per year. The Hawana estimate includes a recommendation on the right SEER level based on your usage pattern and budget.

AC Service Reviews — London Ontario & Southwestern Ontario
138 five-star Google reviews — emergency AC repair zero surcharge honest R-22 advice, annual maintenance drain line save, heat pump grant comparison decisive. Read all ↗
"AC failed on the hottest day of the year in London — a Friday afternoon in July. Called Hawana at 4pm. No surcharge for a Friday afternoon — same rate as a Tuesday morning. Technician within 90 minutes. Diagnosed a failed capacitor and a low refrigerant level from a slow leak. He explained clearly that my system is R-22, the refrigerant has not been made in Canada since 2020, and the recharge would cost around $800 and not fix the underlying leak. Provided both a repair quote and a full replacement quote on the spot. Honest advice and zero surcharge were exactly what you want from a technician on a Friday afternoon in a heat wave."
"Annual AC maintenance appointment in April before the London summer. Technician spent about an hour — cleaned both coils, flushed the condensate drain line (he showed me the algae buildup — would have caused a water leak inside the house within a couple of months), tested the capacitor and contactor. Found the contactor showing pitting and likely to fail during summer. Quoted $180 to replace at the same visit, which I approved. Total cost $329. Preventing an emergency call in August for the contactor alone saved me both money and aggravation. Annual maintenance with Hawana from now on. No monthly subscription — one payment per year."
"Replacing a 14-year-old central AC in London, comparing central AC from $3,500 with a heat pump from $3,700 — both published on Hawana's website. At the estimate, Abdullah ran the Manual J sizing for our 1960s build — higher cooling load than a modern home of the same size. He then explained both options clearly: the heat pump qualifies for OHRSP up to $7,500 and Greener Homes up to $5,000, and also heats in fall and spring, reducing our furnace gas consumption. Both net costs and annual savings estimates laid out. We chose the heat pump. Both grants handled by Hawana. No rental. Invoice matched the written quote exactly."
