Air Conditioning Repair in Burlington
Fast, refrigerant-certified AC diagnosis and repair through the Ontario summer.
An air conditioner that runs but does not cool is telling you something specific — and it is usually one of six things. We test airflow, refrigerant charge, capacitor health, condenser condition, the thermostat circuit and the condensate path before recommending any work.

Local context
AC Repair for Burlington homes
What we find on a ac repair call in Burlington depends almost entirely on when the house was built. Converted cottages are the classic Burlington safety problem: a chimney built for weekend fires now running daily, often with insufficient clearance to combustibles in a renovated wall. A WETT inspection is what your insurer will ask for, and it is what we do here most.
Refrigerant is not consumed by a working system. If your AC is low on charge, there is a leak, and topping it up without finding that leak simply sells you the same repair again next summer. We locate and repair leaks, then charge to the manufacturer's weighed-in specification rather than by feel.
Ontario summers put condensers under real load. A unit choked with cottonwood, grass clippings or a decade of dust will run hot, draw high amperage and shorten its own compressor life long before anything visibly fails. Cleaning and amp-draw testing are part of every service call, not an upsell.
A system that is not cooling is almost never simply low on refrigerant. Refrigerant is a sealed charge — if it is low, it leaked, and adding more without finding the leak buys you one season at most. We measure superheat and subcooling to determine whether the charge is genuinely off, then leak-search rather than top up and leave.
Airflow causes as many summer callbacks as the outdoor unit does. A restricted filter, a dirty evaporator coil or a return that was undersized when the system went in will freeze the coil, and a frozen coil presents as an outdoor unit running constantly with warm air at the registers. We check the indoor side before condemning anything outside.
What the housing stock in Burlington means for this job
Lakeshore Applewood and Rathwood hold converted cottages with added insulation and wood-burning appliances. Inland Applewood North and South are 1990s-to-2010s subdivision stock with gas fireplaces. Sheridan and Pefferlaw run older village homes plus rural propane and oil properties. For ac repair, that matters because the work concentrates on charge, airflow and coil condition — and that is exactly what changes between a Pefferlaw property and a newer build in Willow Beach.
Timing in Burlington
The first genuine heat wave of the season produces most of the year's AC failures in a single week, because that is the first time the system runs continuously. Locally, that plays out like this: Lake Ontario drives hard lake-effect snow and constant humidity off the water. Caps rust faster, crowns crack faster, and wind off the lake causes downdraft and smoke-back complaints that are solved with the right cap rather than a bigger fire.
What it costs here
Capacitors and contactors are inexpensive and stocked; compressors, coil replacements and leak repairs on older refrigerant types are where cost escalates sharply. Travel to the far lakeshore adds time, and shoreline wind exposure means caps, crowns and flashing need replacing more often than inland. Wood-appliance sweeps run longer because of the burn volume.
Permits and jurisdiction
The Town of Burlington issues permits; shoreline properties may also involve conservation authority review. WETT certification is effectively mandatory for insurance on any wood appliance here.

What affects ac repair pricing in Burlington
- Capacitor and contactor faults are the least expensive and most common repairs
- Refrigerant leak repairs vary widely with the location of the leak
- R-22 systems cost significantly more to recharge than R-410A
- Compressor failure is usually a replacement conversation, not a repair one
- Access — rooftop and tight side-yard installs take longer
FAQ
AC Repair questions from Burlington homeowners
Why is my AC running but not cooling?
In order of frequency: a clogged filter or blocked return starving the system of airflow, a failed run capacitor, low refrigerant from a leak, a dirty condenser coil, or a frozen evaporator. A technician can separate these in about 30 minutes with proper gauges.
Should I just add refrigerant?
No. A sealed system does not lose refrigerant unless it has a leak. Adding refrigerant without finding the leak is a temporary fix, is worse for efficiency and is discouraged under Canadian environmental handling rules.
How often should an AC be serviced?
Once a year, ideally in spring before the first hot week. Annual coil cleaning and electrical testing is the single biggest factor in how long a condenser lasts.
My outdoor unit is frozen in July. What does that mean?
Ice means the coil is running below freezing, almost always because of restricted airflow or a low charge. Turn the system off, leave the fan running to thaw it, and book a diagnosis — running it iced up can destroy the compressor.
Do homes here typically have enough return air for their AC?
Lakeshore Applewood and Rathwood hold converted cottages with added insulation and wood-burning appliances. Inland Applewood North and South are 1990s-to-2010s subdivision stock with gas fireplaces. Sheridan and Pefferlaw run older village homes plus rural propane and oil properties. On a ac repair visit in Pefferlaw, Willow Beach, Udora or anywhere else in Burlington, we work from what the house actually is rather than a standard checklist — charge, airflow and coil condition gets assessed on the property, and you get the readings in writing.
When should AC be serviced to avoid a mid-summer failure?
The first genuine heat wave of the season produces most of the year's AC failures in a single week, because that is the first time the system runs continuously. Lake Ontario drives hard lake-effect snow and constant humidity off the water. Caps rust faster, crowns crack faster, and wind off the lake causes downdraft and smoke-back complaints that are solved with the right cap rather than a bigger fire. We cover Burlington from Pefferlaw through Udora, and also serve 3 neighbouring municipalities, so scheduling outside a demand spike usually means a same-week window.
