Car A/C & Heating Repair in Markham
From weak airflow in July to no heat in January, we diagnose and repair vehicle air conditioning and heating systems on cars, trucks and fleet vehicles.
What it is
Your A/C system uses a compressor, condenser and refrigerant to pull heat out of the cabin, while the heater borrows warm coolant from the engine. A small leak, a failing blend door or a tired compressor can leave you sweating or shivering, and a weak defroster is a real safety problem in an Ontario winter.
Signs you should book a visit
- A/C blowing warm or only slightly cool
- Weak airflow from the vents
- Musty smell when the fan runs
- No heat or slow-to-warm heater
- Windows that won’t defog
- Clicking or squealing when the A/C is on
