Cost guide
How much does central air installation cost in the GTA?
A central AC installation in Etobicoke and the GTA typically runs $3,800–$7,500 installed. Where you land depends on the size you need, how efficient a unit you choose, and what we can reuse from your existing setup. Here are the typical ranges, what actually moves the number, and how to tell repair from replace.
Typical cost in the GTA
$3,800–$7,500 installed
Typical installed price for central air conditioning across Etobicoke and the GTA (2026).
| Option | Typical installed price | What you get |
|---|---|---|
| Entry SEER2, standard home | $3,800–$4,500 | Right-sized cooling at the lowest up-front cost. |
| Mid-efficiency | $4,500–$5,500 | A quieter unit with lower running costs over Ontario summers. |
| High-efficiency, larger home | $5,500–$7,500 | Top SEER2 efficiency and even cooling for bigger or sunnier homes. |
These are typical GTA installed ranges, not a quote. Your exact price depends on the size you need, whether your line set and coil can be reused, and your electrical — we assess it and give you a written, all-in price for free.
What moves the price
What actually drives the cost
Size & output (tonnage)
The unit has to match your home — an oversized AC short-cycles and an undersized one runs flat-out. We size it properly rather than rounding up.
Efficiency (SEER2)
A higher-SEER2 unit costs more up front but cuts running costs over Ontario summers. We show you the trade-off for your usage.
Existing line set & coil
Whether the refrigerant lines and indoor evaporator coil can be reused or need replacing is one of the bigger swings in price.
Electrical & placement
Breaker capacity, a level condenser pad, and easy access to the outdoor unit all factor into the labour.
Old-unit removal
Safe recovery of the old refrigerant and disposal of the old condenser is part of a proper install.
Refrigerant type
New 2026 systems use low-GWP refrigerant (R-32 / R-454B). An old R-410A system can't be retrofitted, so a failing one is a replacement, not a recharge.
Repair or replace your AC?
If your air conditioner still runs on R-22 refrigerant, is over 12–15 years old, or a repair is approaching half the cost of a new system, replacing usually beats paying for repeated fixes — and a higher-SEER2 unit cuts running costs over our summers. We'll show you the numbers both ways before you decide.

Central Air Installation Cost FAQs
How much does central air installation cost in the GTA?
A central AC install in Etobicoke and the GTA typically runs $3,800–$7,500. An entry SEER2 unit for a standard home is usually $3,800–$4,500; a high-efficiency unit for a larger home runs $5,500–$7,500. Your exact price depends on sizing, whether your line set and coil can be reused, and electrical — we give you a written, all-in number for free.
What size air conditioner do I need?
We size it to your home, not a rule of thumb. Square footage, sun exposure, insulation, and humidity all matter — an oversized unit cools unevenly and short-cycles.
Does a higher-efficiency AC really pay off?
Over a few Ontario summers, a higher-SEER2 unit can offset its higher up-front cost in lower bills. We'll lay out the payback for your situation honestly.
Can you reuse my old line set?
Sometimes — it depends on the condition and whether it suits the new refrigerant. We check it during the estimate; reusing it where it's sound keeps your cost down.
