Aircon Servicing & Repair in Mississauga

A standard service covers cleaning or replacing filters, cleaning the evaporator coil and blower, flushing the drainage tray and pipe, checking refrigerant pressure, testing thermostat and controls, and inspecting electrical connections. It does not include repairs, parts, or refrigerant top-ups — those are quoted separately.

Dirty coils and filters make the compressor work harder for the same cooling — energy use can rise 15-30% before you notice weaker airflow. A failing capacitor or low refrigerant has the same effect. A service that restores the unit to spec usually pays for itself in a hot season.

A standard clean-and-check takes 30-45 minutes per indoor unit. A chemical wash takes about an hour per unit, and a full chemical overhaul (where the unit is dismantled) takes 1.5-2 hours per unit. Multi-unit visits are faster per unit.

A unit that trips the breaker at startup usually has a failing compressor, a shorted capacitor, or a wiring fault — all electrical faults that need a technician. Do not keep resetting the breaker; repeated tripping can damage the compressor beyond repair.

If you run multiple units daily, yes — contracts usually price each visit 15-30% below one-off rates, include priority booking during heatwaves, and some include minor parts. For a single, lightly used unit, paying per visit is usually cheaper.

Yes — federal and provincial programs (e.g. Canada Greener Homes-successor programs, provincial utility rebates) offer meaningful rebates for replacing AC/furnace setups with cold-climate heat pumps. Amounts change by province and year, so ask the contractor which programs your equipment qualifies for and get it in writing.

May-June, before the short cooling season peaks. Many homeowners bundle a spring AC tune-up with a fall furnace service; combined maintenance plans typically cost less than two separate visits.
