AC Installation & Repair Toronto | Same-Day Air Conditioning Service

A standard central air conditioner replacement typically takes 4 to 6 hours. A new installation requiring ductwork may take one to two days. We offer same-day AC installation for most replacement jobs in the GTA.

AC sizing depends on your home's square footage, ceiling height, insulation, and sun exposure. A unit that is too small will run constantly and not cool properly. One that is too large will short-cycle, causing humidity issues. Our technicians perform a proper Manual J load calculation to recommend the right size.

A central air conditioner installation in Toronto typically ranges from $3,200 to $6,500 installed, depending on the unit's efficiency (SEER rating), brand, and any required electrical or ductwork upgrades. We offer free in-home estimates with no obligation.

SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an AC unit cools. Higher SEER means lower operating costs. Ontario minimum is 13 SEER. We recommend 16 to 20 SEER for most GTA homes - the energy savings typically pay back the premium cost within 4 to 7 years.

We recommend an annual AC tune-up every spring before the cooling season begins. Regular maintenance extends equipment life by 3 to 5 years, improves efficiency, and catches small problems before they become expensive breakdowns during a July heat wave.

A ductless mini-split is an air conditioner (and often a heat pump) that does not require ductwork. It is ideal for room additions, older homes without ducts, garages, or any space where extending ductwork is not practical. They offer zoned control, quiet operation, and can be more efficient than central AC.

Yes - for most Ontario homeowners, a cold-climate heat pump is worth it. Modern heat pumps are 2 to 3 times more efficient than electric baseboard heating and can significantly reduce gas bills when used as a hybrid system. Enbridge rebates of up to $10,000 are available in 2025-2026, and the Canada Greener Homes program offers up to $5,000 more. Heat pumps also provide air conditioning in summer, replacing two systems with one.

Signs your AC is low on refrigerant include: warm air blowing from vents, ice forming on the refrigerant lines or indoor coil, a hissing or bubbling sound near the unit, and much longer cooling times. Low refrigerant always indicates a leak - simply topping it up without finding the leak will not fix the problem. Our TSSA-certified technicians will locate the leak, repair it, and recharge to the correct level.
