Central air added to an older brick house, a newer townhouse unit, a mini-split in a rental: we repair cooling of every kind in Hamilton and price it before we begin.
Prices before HST. You agree to the price before the repair starts.
📞 Call (647) 677-003761% of Hamilton homes were built before 1981, and many of them had central air added years later on ducts built for heat. Small upstairs supply runs and few returns leave top floors warm, and a starved coil can ice over. We check the charge and the coil, then measure airflow upstairs before recommending anything.

Look for the year on the outdoor unit. It decides how much a repair is worth:
| Year on the label | Usually |
|---|---|
| Since 2016 | Worth repairing; check the warranty first |
| 2010 to 2015 | Generally worth repairing |
| Earlier than 2010 | Probably R-22, which is costly to recharge |
A third of Hamilton households (34%) rent. Where a rental unit's air conditioning belongs to the landlord, the landlord arranges the repair, so tenants should report the problem to them first. Landlords and property managers can book with us by phone at any hour.

Row houses are 12% of Hamilton homes, and many older houses sit close together on narrow lots. An outdoor unit squeezed into a side passage or behind a fence runs hot and trips on hot afternoons, so we check its clearance on every call.

Before HST. An older unit needing a compressor or a large leak fixed costs more; you hear the price before we start.
A unit over 15 years old, or one running on R-22, is rarely worth a major repair. New central air starts at $4,000 installed, or rent one for $44.95 a month with repairs covered, and same-day installation is available on many jobs. See air conditioners.
Where the ducts can carry it, a central heat pump replaces the AC and heats much of the year; where they cannot, ductless heads cool and heat the rooms that need it. See heat pumps in Hamilton.
