How AC Replacement Works
From your first call to a cool home, usually completed in one day.
We visit your home, inspect the existing system, and perform a cooling load calculation. You receive a written quote before we leave. No obligation.
We walk you through Lennox, Goodman, and Carrier options at different efficiency levels (SEER ratings). We'll explain the payback period for each so you can make an informed decision.
We complete most AC in a single day. Our two-person crew removes the old unit, installs the new system, and verifies cooling before they leave.
EcoFrost pulls the required permit and arranges the municipal inspection. We give you all documentation for your records and warranty file.

Common Questions About AC Replacement
A complete central AC replacement in Ontario typically costs $3,500–$7,000 installed. A standard 14 SEER2 unit runs $3,500–$4,500. A premium variable-speed high-efficiency system costs $6,000–$7,000. Prices include permits, labour, and old equipment disposal. EcoFrost offers 0% financing for 6 months (via Financeit; standard rate applies after the promo period).
A two-person EcoFrost crew completes most central AC replacements in 4-6 hours. In most cases, you'll have cooling restored the same day the old unit is removed.
AC sizing is based on a cooling load calculation (Manual J) considering your home's square footage, insulation, window area, and ceiling height. Oversizing is a common mistake: an oversized AC short-cycles, creating humidity problems and wearing out faster. EcoFrost performs a full calculation on every estimate.
If your furnace is over 15 years old, replacing both systems together can save on labour and lets us match the new AC coil to your air handler. Ask for a combo quote; EcoFrost often offers a discount for system pairs.
