When the house will not cool, we find out why: refrigerant, electrical parts or airflow. We repair central air conditioners, heat pumps and ductless systems of every brand across Oakville, and you approve the price first.
Typical ranges, not quotes, plus HST. We agree your price before the repair starts.
📞 Call (647) 677-0037With 35% of Oakville homes built from 1981 to 2000 and 20% from 2001 to 2010, many outdoor units here are either a replacement from the 2000s or the builder's original. Central air usually lasts 12 to 15 years. The year on the nameplate decides how much to spend:
| Nameplate year | Our usual advice |
|---|---|
| 2016 onward | Repair, and ask the manufacturer about the parts warranty |
| 2010 to 2015 | Repair most faults; these normally run on R-410A |
| 2009 or older | Likely R-22, which is costly to recharge: price a replacement first |

Row houses are 17% of Oakville homes, and their outdoor units often share a small patio with the barbecue, a privacy fence or the neighbour's unit. A condenser that cannot shed its hot air overheats and trips, especially in a heat wave. We check its clearance on every repair, and in a condo townhouse we work within the corporation's rules on access.

On larger Oakville lots the condenser is often tucked behind cedars, shrubs or a decorative screen. Plants grow, seed fluff and grass clippings pack into the coil, and the unit loses capacity. Keep plants well back from every side and trim anything overhead. A dirty outdoor coil is a frequent reason an AC runs all afternoon without catching up.
| Cooling job | Usual cost |
|---|---|
| AC repair, typical, all-in | $350 to $950 |
| Mini-split or heat pump repair | $400 to $1,200 |
| AC tune-up, spring or summer | $150 to $250 |
| Air conditioner rented from GT | $0, repair costs covered |
Same as Brampton, before HST. An old unit that needs a compressor or a big leak repair can cost more, and you hear that before any work.
If the unit is past 15 years, uses R-22 or needs a compressor, replacing it usually makes more sense. New central air starts at $4,000 installed in Oakville, or you can rent one at $44.95 a month, repairs included. Compare AC installation in Oakville with a heat pump.
Sunrooms, rooms over the garage and finished basements are often warmer or cooler than the rest of an Oakville house. A single ductless head handles that room on its own, for cooling and heating, from $2,800 installed. See ductless mini-splits.
