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.
✓ 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.
Month-by-Month Guide — London Ontario AC Timing
Here is what each month looks like for AC purchases in London Ontario, based on what Hawana sees in actual scheduling and equipment availability each year.
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.

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.
