What an Air Conditioner Service Visit Includes
A service visit, or tune-up, is a set of checks that keeps the air conditioner close to its rated efficiency and catches small faults before they become a breakdown in a heat wave. Book it in spring, before the first hot week. This is what the technician does:
- Cleans the outdoor condenser coil so the system can reject heat properly.
- Checks the refrigerant charge and pressures. A low charge means a leak, which is found and repaired rather than topped up.
- Tests the capacitor and the contactor, the two parts behind most no-start calls.
- Tightens electrical connections and measures the current the compressor and the fan motors draw.
- Clears the condensate drain and checks the pan, the usual cause of water on the floor.
- Checks the filter, the indoor coil and the blower for airflow.
- Measures the temperature difference between the supply and the return air.
- Tests the thermostat and runs the system through a full cycle.
AC Repair, Installation and Maintenance in Mississauga
Air conditioner repair
An air conditioner that runs but does not cool, freezes up, leaks water or trips its breaker needs a diagnosis, not a guess. See AC repair Mississauga for the common faults and how repairs are quoted, or start with our checks for an AC that is not cooling.
Air conditioner installation
A new system is sized to the house, not copied from the old one: a unit that is too large cools fast, shuts off early and leaves the house damp. See air conditioner installation in Mississauga, what drives installation cost, and whether to rent or buy an air conditioner. Not sure the old unit is finished? Read when to replace an air conditioner.
Air conditioner maintenance
A yearly tune-up is the cheapest way to avoid a mid-summer breakdown, and manufacturers can ask for maintenance records on a warranty claim. See air conditioner maintenance in Mississauga, our protection plans, which include an annual preventative maintenance and tune-up, and what an air conditioner warranty covers.
When to Call for Emergency AC Service in Mississauga
- No cooling: the system runs but the air from the vents is warm, or the house keeps getting warmer.
- Ice on the refrigerant lines or the indoor coil. Switch the system off and let it thaw before the technician arrives.
- A burning smell, or a breaker that trips again after one reset. Leave it off.
- Water leaking around the furnace or the air handler.
- Complete shutdown: the system will not start at all.
What to Do While You Wait
- Check the simple things once: the thermostat is set to cool, the filter is not clogged and the breaker has not tripped.
- Switch the system off if it is iced up, leaking or smells of burning. Running it can turn a small repair into a large one.
- Keep the heat out: close blinds on sunny windows, run ceiling fans and avoid using the oven until the repair is done.

Air Conditioner Service in Mississauga: FAQ
How much does AC repair cost in Mississauga?
Typical air conditioner repairs cost $200–$650 in the Mississauga area. Refrigerant leaks and capacitor or fan motor replacements are the most common jobs. Compressor issues cost more and may justify replacement on older units.
Why is my AC running but not cooling?
Usually a clogged filter, dirty condenser coils, or low refrigerant. Check and replace the filter first, then make sure the outdoor unit is clear of debris. If it still blows warm air, a technician should test refrigerant levels.
Do you repair all AC brands?
Yes — Aire One Peel services all major brands including Carrier, Lennox, Goodman, Trane, and Daikin, and is an authorized Carrier dealer.
How fast can you come for an AC repair?
Same-day AC repair is available in most of Peel Region, with 24/7 emergency service during heat waves. Call 905-564-8545.
What does an air conditioner tune-up include?
The technician cleans the outdoor condenser coil, checks the refrigerant charge and pressures, tests the capacitor and the contactor, tightens electrical connections, clears the condensate drain, checks the filter, the indoor coil and the blower, measures the temperature difference between the supply and the return air, and runs the system through a full cycle.
How often should an air conditioner be serviced?
Once a year, ideally in spring before the first hot week. A heat pump works in both seasons, so it benefits from a check before winter as well. Between visits, check the filter monthly during the cooling season and keep the outdoor unit clear of leaves and grass clippings.
