Aircon Servicing & Repair in Montréal

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.

Inverter units vary compressor speed instead of switching on and off, so they hold temperature more steadily and cost 20-40% less to run for long daily use. Non-inverter units are cheaper upfront and fine for rooms cooled a few hours a day. For daily whole-day use, the inverter premium usually pays back in 2-3 years.

Check the simple things first: thermostat mode and setpoint, dirty filters, and blocked outdoor unit airflow. If those are fine, the usual culprits are low refrigerant from a leak, a failed capacitor or fan motor, or a dirty coil. Low refrigerant always means a leak — a technician should find and fix the leak, not just top up the gas.

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.
