Heat Pump Repair · Burlington, OntarioHeat Pump Repair in Burlington
If your outdoor unit is a block of ice, blowing cool air in heating mode or stuck in the wrong season, heat pump repair in Burlington begins with a $90–$150 diagnostic visit, and most fixes cost $150–$800. Switch the thermostat to emergency or backup heat, leave the ice alone and call (647) 801-1252. The shop is at 4145 North Service Road, inside the city.
Burlington heat pump repair for iced coils, cold air and stuck modes
Start by separating normal from broken. A light frost on the outdoor coil, a puff of steam and a few minutes of cooler air at the vents is a defrost cycle doing its job. A coil sealed in ice from top to bottom, ice on the fan blades, or a unit that has run for hours while the house loses ground is a fault, and so is cooling when you asked for heat. In that second group, shut the heat pump off and run the backup so the compressor is not damaged while you wait.
Four parts account for most of what we replace. The defrost control board and the coil temperature sensor decide when the unit melts its frost, and when either fails the coil ices over in a day of wet snow; the reversing valve switches between heating and cooling and can stick halfway, leaving lukewarm air in both modes; and the outdoor fan motor seizes when ice reaches the blades. Conventional units also share an air conditioner's capacitor and contactor, while inverter models from Mitsubishi, Daikin and Fujitsu report fault codes that point to a board or a sensor. Sensors, capacitors and contactors ride on the truck, and a board or valve is ordered for the specific model.
How urgent the call is depends on what backs the heat pump up. Hybrid systems in Millcroft, the Orchard and Alton Village still have a gas furnace, so setting the thermostat to furnace-only keeps the house warm at normal cost while the part arrives. North of the Escarpment in Lowville and Kilbride, an all-electric home falls back on resistance strips that keep you warm but use far more electricity than the heat pump did, so say so when you call and we treat it as a no-heat risk. A ductless head that drips down the wall of a Roseland or Aldershot bungalow is rarely urgent: turn that head off and book a regular visit.
Age and paperwork shape the bill. A heat pump installed in the last few years is usually still inside the manufacturer's parts warranty, so we check the registration before quoting a part you should not be paying for. Refrigerant work needs an ODP card, newer units on R-32 or R-454B need their own recovery equipment, and a breaker that keeps tripping is an electrical fault to be repaired to ESA rules, not reset again. When a compressor fails on a unit past 12 to 15 years we price the repair beside heat pump installation in Burlington at $9,500–$15,000 before rebates; the heat pump repair service page covers symptoms in depth, seasonal heat pump maintenance in Burlington prevents most defrost faults, and you can book a diagnostic any day.

Heat Pump Repair in Burlington — FAQs
How much does heat pump repair cost in Burlington?
Most repairs fall between $150 and $800, and the diagnostic visit is $90–$150, folded into the repair when you approve it. Sensors, capacitors and contactors sit at the low end, with defrost boards and fan motors above them. Reversing valves and compressors are quoted individually because the refrigerant has to be recovered first. The number is on paper before a single part is ordered.
Should I turn my heat pump off if it is iced over?
Yes, if the ice is solid and has not cleared after a couple of hours. Switch the thermostat to emergency or backup heat, shut the outdoor unit off, and clear snow from around the base without touching the fins. Do not chip the ice or pour hot water on the coil. Why a heat pump ices up explains the causes while you wait for the visit.
My heat pump is blowing cold air. Is it broken?
Not if it lasts a few minutes and comes with steam off the outdoor unit: that is defrost. Air from a heat pump is also cooler than furnace air even when everything is working. It is a fault when the cool air continues, the outdoor unit is silent or iced, or the thermostat shows auxiliary heat running constantly. Those point to a sensor, a board, the reversing valve or low refrigerant.
Do you repair heat pumps you did not install?
Yes. Have the model number from the outdoor unit's nameplate and any code on the thermostat or indoor head ready when you call. With those we can check whether the unit is under parts warranty and which components are likely, which decides what goes on the truck. Burlington addresses from Aldershot to Alton Village and north to Kilbride are all local calls for us.
Does a heat pump repair cost more at night or on a weekend?
No. ZK Mechanical charges the same rate at night, on weekends and on holidays as on a weekday, and the line is answered 24/7. If you have working backup heat, a daytime visit is usually easier for parts supply. If the backup is also down in freezing weather, call the emergency line; emergency HVAC repair in Burlington explains what to do in the meantime.
