Diagnostics
AC Problems We Fix Every Day
Most are solved same-day with parts we carry on our trucks.
AC Not Cooling
Low refrigerant, dirty condenser coils, failing compressor, or a frozen evaporator coil — the most common summer call we get across Toronto.
$150 – $600
AC Blowing Warm Air
Refrigerant leak, compressor failure, thermostat misconfiguration, or a clogged filter. We check every component to find the root cause.
$100 – $450
Water Leaking from AC
Clogged condensate drain, frozen coil, or cracked drain pan. Toronto humidity makes drain clogs one of the most frequent summer calls.
$100 – $350
AC Short Cycling
The system turns on and off without completing a cycle — usually an oversized unit, dirty filter, low refrigerant, or electrical fault.
$100 – $400
Strange Noises
Grinding, squealing, or rattling from the indoor or outdoor unit. Usually a failing fan motor, loose hardware, or compressor trouble.
$150 – $500
Uneven Cooling
Some rooms cold, others warm — common in multi-storey Toronto homes. Often ductwork, sizing, or a failing blower. Zoning available.
$150 – $400

Common Questions
AC Repair Toronto — FAQ
How much does AC repair cost in Toronto?
AC repair in Toronto typically costs between $150 and $600 depending on the issue. Common repairs like capacitor replacement, thermostat recalibration, or fan motor repair run $150 to $300. More complex work such as compressor repair, refrigerant leak detection, or evaporator coil replacement ranges from $300 to $600. We always diagnose the problem and provide a clear price before starting any work.
Do you offer 24/7 emergency AC repair in Toronto?
Yes. We provide around-the-clock emergency AC repair across all of Toronto and the GTA. A failed AC system in the middle of a Toronto heat wave is a health risk, especially for seniors and young children. Call (416) 286-5665 at any time and we dispatch a TSSA-certified technician. No extra diagnostic fees for evenings or weekends.
What areas of Toronto do you cover for AC repair?
We service every Toronto neighbourhood including downtown, midtown, Scarborough, North York, Etobicoke, East York, the Beaches, Leslieville, High Park, Junction, Roncesvalles, Yorkville, and the entire GTA. Our technicians are positioned across the city for fast response times regardless of where you are located.
How long does a new AC installation take in Toronto?
Most central AC installations are completed in a single day, typically 4 to 8 hours. This includes removing the old unit, setting the new outdoor condenser, connecting refrigerant lines, electrical wiring, thermostat setup, and full system testing. Ductless mini-split installations take 3 to 5 hours for a single zone. We always provide a time estimate before starting.
What SEER rating should I choose for my Toronto home?
We recommend a minimum of 16 SEER for Toronto homes. A 16 SEER unit uses about 25 percent less electricity than a baseline 14 SEER model, which adds up significantly over a Toronto summer. For maximum efficiency, 18 to 21 SEER models with variable-speed compressors offer the lowest operating costs and most consistent temperatures. Higher SEER units cost more upfront but pay for themselves within 3 to 5 years.
When should I replace my AC instead of repairing it?
Consider replacing your AC if it is over 10 to 12 years old, uses R-22 refrigerant (Freon, which has been phased out and is extremely expensive to recharge), needs a compressor replacement, or if the repair cost is more than half the price of a new unit. Also consider replacement if your cooling bills keep rising despite regular maintenance. A modern 16 SEER unit costs $3,500 to $6,000 installed and uses 25 to 40 percent less electricity than an older 10 to 12 SEER system.
