Warm air from the vents, a frozen coil or a unit that trips the breaker on the hottest day of the year? O2 HVAC repairs central air conditioners and ductless mini splits across Abbotsford, fast.

Air conditioners in Abbotsford don’t get a gentle workload. The city hit 42.9°C in June 2021, and the hottest days are exactly when worn capacitors, clogged coils and low refrigerant finally give out. With smoke from wildfires reaching the Fraser Valley most summers, filters and coils clog faster too.
O2 HVAC provides air conditioning repair services for central AC and ductless mini splits. Every repair starts with a full diagnosis, our vans carry the parts that fail most often, and you approve the price before we start.

Here’s what causes most air conditioner breakdowns each summer, and what we do about it. Most of these are fixed in a single visit, usually within an hour or two of arriving.
The most common summer repair. Heat wears capacitors out, and the outdoor unit hums but won’t start.
Dust, cottonwood fluff and wildfire smoke clog the outdoor coil, so the system can’t shed heat and overheats on hot afternoons.
Usually caused by a dirty filter, weak airflow or low refrigerant.
Low refrigerant means poor cooling and a frozen coil. We find and fix the leak before recharging, rather than topping it up every summer.
Algae and dirt block the drain line, and water backs up and leaks onto the floor.
The outdoor fan stops spinning or the unit won’t switch on.
Thermostat and wiring faults, including smart thermostats set up for heating but not cooling.
Heat pump not heating or covered in ice? Heat pump repair and service has its own section on our Heat Pump Installation & Repair page.
Set it to Cool, with the temperature below room temperature, and check the batteries.
A clogged filter can freeze the coil. Replace it if you can’t see light through it.
Check the breakers for the furnace or air handler and the outdoor unit.
Make sure the switch or pull-out block in the box beside the outdoor unit is on.
If you see ice, turn the AC off and run the fan only for a few hours before restarting it.
Still not cooling? Call us rather than resetting it again and again, which can damage the compressor.
Most AC breakdowns in a heat wave start as small problems a yearly visit would catch. Our AC service in Abbotsford includes:
Book it in April or May, before the first hot spell. If smoke was heavy last summer, it’s worth a coil and filter check before the next one.
You’ll always get the price before we start. Compressor cost depends on the system size and whether it’s still under warranty.

There are plenty of AC repair companies in Abbotsford. Here’s what you get with O2 as your air conditioning repair contractor:
We provide air conditioner repair and service in every Abbotsford neighbourhood, including Clearbrook, Historic Downtown, Mill Lake, Auguston, Eagle Mountain, Sandy Hill, Townline Hill, Aberdeen, Mount Lehman, Bradner, Matsqui and Sumas Prairie. We also serve Chilliwack and Mission.
Common causes are a dirty filter, a failed capacitor that stops the outdoor unit, a dirty condenser coil or low refrigerant. Check the filter and breakers first, then call us.
Ice usually means poor airflow from a dirty filter or blocked vents, or low refrigerant from a leak. Turn the AC off, run the fan to melt the ice and book a repair.
The condensate drain line is usually clogged, or the drain pan is cracked. Leave it and it can damage your floor or ceiling.
Once a year for a central AC; heat pumps, which run year-round, benefit from a check in spring and a quick look in fall.
Yes. We repair and service all major mini split brands, including error codes, drain problems and dirty indoor coils.
Small electrical repairs, yes. A refrigerant leak on an R-22 system is usually not, because the refrigerant is scarce and expensive. A new heat pump is often the better investment.
