How much does air conditioner installation cost in Mississauga?
Short answer: a high-SEER2 central air conditioner installed in a Mississauga home typically runs $4,000 to $6,500 CAD, a ductless mini-split $5,000 to $15,000 CAD depending on how many indoor heads the home needs, and a cold-climate heat pump that cools in summer and heats in winter $13,000 to $20,000 CAD. Your own number depends on the size of the unit, the condition of your ductwork and electrical panel, and where the outdoor unit has to sit. We put the exact price in writing in a free in-home estimate before any work starts.
| System | Best for | Efficiency measure | Typical installed range |
|---|---|---|---|
| High-SEER2 central air conditioner | Homes with ducts that only need cooling | SEER2 16 or higher | $4,000 to $6,500 CAD |
| Ductless mini-split | Homes, additions or upper floors without ducts | SEER2 and HSPF2 | $5,000 to $15,000 CAD |
| Cold-climate heat pump | Replacing the AC and cutting the heating bill at the same time | SEER2 and HSPF2 | $13,000 to $20,000 CAD |

What moves the price up or down
- Size of the unit. Tonnage is set by a heat gain calculation, not by the price list, and a bigger unit is not a better one.
- Ductwork. Ducts in good shape can carry the new system; undersized returns, leaking joints or a coil that no longer fits add labour and material.
- Electrical. Most straight AC changeouts reuse the existing circuit. Older panels, or a move to a heat pump, sometimes need a licensed electrical upgrade first.
- Where the outdoor unit goes. A long line set, a rooftop or a tight side yard costs more than a simple pad beside the old one.
- Efficiency level. Moving from a base model to SEER2 16 or higher raises the upfront price and lowers the summer hydro bill.
- Buying versus renting. If the upfront number is the problem, compare the options on our rent or buy an air conditioner page before you decide.
Rebates on cooling in Ontario
The live provincial program is the Home Renovation Savings Program from Enbridge Gas and Save on Energy, and its money is aimed at heat pumps rather than cooling-only air conditioners: up to $7,500 CAD for a cold-climate air-source heat pump in homes heated with electricity, oil, propane or wood (up to $2,000 CAD in natural gas homes), and up to $12,000 CAD for a ground-source system, as of October 2026. If a rebate matters to your budget, ask us to price a heat pump installation beside the straight AC swap so you can compare the two on paper.
How long an AC installation takes
A straightforward changeout is a one-day job, usually about four to eight hours from the truck arriving to the system running. Rebuilding ductwork, relocating the indoor coil or an electrical panel upgrade can push it into a second day. You hear which of those apply at the estimate, not on installation day.
How we size your air conditioner
Sizing is a calculation, not a guess from square footage. A CSA F280-12 heat gain calculation takes in floor area, insulation, window area and orientation, air tightness and how many people live in the house, and that is what sets the tonnage. Getting it wrong costs you twice. An oversized unit cools the air fast, shuts off before it has pulled the moisture out and leaves the house cold and clammy, and the short cycling wears the compressor out early. An undersized unit runs all afternoon on the hottest days and never catches up. If your current system cools but the house still feels damp, our guide on an AC that is not removing humidity covers the usual causes.
