Car A/C & Heating Repair in Guelph
If the A/C blows warm or the heater blows cold, there's a reason — and it's rarely 'just needs a recharge'.
Automotive A/C is a sealed system. If it's low on refrigerant, it leaked, and topping it up without finding the leak just buys a few weeks. We do it properly: performance test, pressure readings, dye or electronic leak detection, and a diagnosis of the actual fault — a seal, a condenser holed by a stone on the 401, a compressor clutch, a blend-door actuator — before quoting the repair. Recharges use the correct refrigerant for your vehicle (R-134a or R-1234yf) and the right oil charge.

Heating
No heat in a Guelph January is a safety issue — you can't defrost. Common causes are a low coolant level (find the leak), a stuck thermostat, a plugged heater core, a failed blend-door actuator or a dead blower motor or resistor. We diagnose and fix all of them.
Timing
Book A/C work in May before the first heat wave, and heating work in October before the first frost — both fill up the week the weather turns.
Frequently asked questions
How much does car A/C repair cost in Guelph?
Diagnosis and a recharge with dye typically runs $150–$300. Repairs range from under $200 for a seal or line to $1,000+ for a compressor. We quote after diagnosis, not before.
Why does my A/C work for a while and then stop?
Usually a slow leak, sometimes a compressor clutch or a pressure switch cycling. The diagnosis tells us which.
Do you handle R-1234yf systems?
Yes — most vehicles from about 2017 on use it, and it needs its own equipment.
My heater smells sweet — what is that?
Coolant, almost certainly from a leaking heater core. Get it looked at before it fogs the windshield or leaves you without heat.
