Toronto AC Replacement
Should You Repair or Replace Your AC?
Not every AC problem means you need a new system. If your unit is under 10 years old, this is a first breakdown, and the fix is a capacitor, contactor, or fan motor, repair is almost always the better financial call. Our AC repair Toronto page covers same-day fixes from $150.
Replacement makes more sense once your AC passes 10 to 12 years old, uses R-22 refrigerant (phased out and increasingly expensive), needs compressor work, or a single repair would cost more than half the price of a new unit. Electricity bills that keep climbing despite regular maintenance are another sign — older 8–10 SEER units use nearly twice the electricity of a modern 16+ SEER2 system.

Common Questions
AC Replacement Toronto — FAQ
How much does AC replacement cost in Toronto?
A complete central AC replacement in Toronto typically costs $3,800 to $7,500 in 2026. This includes the outdoor condenser, indoor evaporator coil, refrigerant lines, electrical work, permits, and labour. The final price depends primarily on the SEER2 efficiency rating and whether you choose a single-stage, two-stage, or variable-speed system. See our full 2026 AC installation cost guide for the line-item breakdown.
When should I replace my AC instead of repairing it?
Replace if your AC is over 10 to 12 years old, uses R-22 refrigerant (phased out and expensive to recharge), needs a compressor replacement, or the repair cost is more than half the price of a new unit. Rising electricity bills despite regular maintenance are another sign your system is losing efficiency. If your unit is under 10 years old and the fix is a capacitor, contactor, or fan motor, repair is almost always the better call.
How long does an AC replacement take?
A standard central AC replacement takes 4 to 8 hours in a single day. This includes removing the old unit, setting the new outdoor condenser, connecting refrigerant lines, electrical wiring, thermostat setup, and full system testing. If electrical upgrades are needed, or if we are replacing both the AC and furnace together, it may extend to two days.
What AC brands do you install?
We are an Authorized Lennox Dealer and also install Goodman, Fujitsu, Daikin, and Ducane. Every system is sized with a proper Manual J load calculation rather than matched to the old unit's nameplate, because an oversized AC short-cycles and creates humidity problems, while an undersized unit runs constantly and can't keep up on hot days.
Does a new AC qualify for a rebate?
No. A standalone air conditioner is not eligible for Ontario's Home Renovation Savings program — that rebate is reserved for cold-climate heat pumps, which cool in summer and heat in winter. As a certified Enbridge Sustain Trusted Partner, we can install a new AC with $0 down through the lease-to-own program instead, with maintenance included in one monthly payment.
What SEER2 rating should I choose for my Toronto home?
We recommend a minimum of 16 SEER2 for Toronto homes. A 16 SEER2 unit uses roughly 15 to 25 percent less electricity than a baseline 14 SEER2 model, which adds up over a Toronto summer. For maximum efficiency, 20 to 26 SEER2 variable-speed systems offer the lowest operating costs, the quietest operation, and the most consistent temperatures — they cost more upfront but pay back through lower hydro bills.
