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.

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.
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.

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.

Abdullah Ghzail — TSSA Certified Technician & Founder
“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.”
“Hawana installed a new central AC in our London home. Abdullah came out for the load calculation, recommended the right Carrier unit, and his crew completed the full installation in 5 hours. Price was significantly lower than two other London Ontario quotes I received — and those other quotes didn’t even include the permit.”
“Installed a ductless mini-split in our addition. Proper load calculation, clean installation, and the price was better than every other London Ontario quote we received. Abdullah also explained what rebates we might qualify for. Really appreciated the transparency.”
