Heat Pump Repair · Caledon, OntarioHeat Pump Repair in Caledon
Heat pump repair in Caledon starts with one question: is the backup heat holding the house? If it is, book a daytime visit; if there is no backup and the indoor temperature is falling during a freeze, call the 24/7 line, because a home on a well has pipes and a pressure tank to protect. Most repairs cost $150–$800 after a $90–$150 diagnostic that is credited when you go ahead.
Heat pump not heating in Caledon: what fails, what it costs and when to call
Start by ruling out the things that are not faults. A cold-climate heat pump steams and blows cool air for a few minutes while it defrosts, and white frost on the coil on a -10°C morning is normal. A solid shell of ice that never clears, an outdoor fan that will not spin, a breaker that trips on start-up, or heating that has turned into cooling are real faults. Before you call, check both breakers (the outdoor unit and the indoor air handler are on separate ones), clear drifted snow from around the unit, change the filter and confirm the thermostat is set to heat.
Three causes come up more in Caledon than in town. Wind across open fields packs snow into the coil faster than the defrost cycle can clear it, freezing rain can lock the fan blades, and a unit mounted too low sits in its own refrozen meltwater. Rural power is rougher: outages and voltage dips on long Hydro One feeders are hard on capacitors, contactors and inverter boards, which often fail on the restart. And field mice winter inside outdoor cabinets, where they chew the low-voltage control wiring and leave a unit that is dead for no visible reason.
The parts that fail sort by price. A capacitor or contactor is $150–$350 and travels on the truck. An outdoor fan motor or indoor blower motor is $300–$700, a defrost or control board is $400–$800, and finding and sealing a refrigerant leak, then recharging to the nameplate weight, is $300–$800 or more. A reversing valve stuck between heating and cooling and a failed compressor are quoted case by case. Refrigerant work in Ontario requires an ODP card, which our technicians hold alongside the TSSA gas licence that covers the furnace half of a hybrid.
While you wait, run the backup on purpose. Set the thermostat to emergency heat so the strips or the propane furnace carry the house and the damaged outdoor unit stays off. Replace instead of repairing when the unit is past 12 to 15 years and the fault is the compressor or the reversing valve; for that comparison see heat pump installation in Caledon. Because Caledon is our longest run from Burlington, we triage by phone first, and some calls end there. The heat pump repair page lists the symptoms, the Caledon service area page covers our other work in town, and you can book a diagnostic at any hour.

Heat Pump Repair in Caledon — FAQs
How much does heat pump repair cost in Caledon?
Most repairs fall between $150 and $800 once the $90–$150 diagnostic is credited. Capacitors and contactors are $150–$350, fan and blower motors $300–$700, defrost and control boards $400–$800, and a leak repair with recharge $300–$800 or more. Compressors and reversing valves are quoted individually. The 24/7 line carries no overtime, weekend or holiday surcharge, so a Sunday night call is priced like a Tuesday morning one.
My heat pump is covered in ice. Is that an emergency?
Frost that comes and goes is the defrost cycle working. A casing of solid ice that stays for hours is a fault: a failed defrost sensor or board, a dead fan, low charge, or snow blocking the airflow. Switch to emergency heat, clear loose snow by hand and do not chip at the coil with a tool. How the defrost cycle works shows what normal looks like.
Can I use emergency heat until the heat pump is fixed?
Yes, that is what it is for. Emergency heat shuts the outdoor unit off and runs the backup alone: electric strips in an all-electric system, or the propane or gas furnace in a hybrid. A furnace can carry the house indefinitely. Strips can too, but they use roughly two to three times the electricity the heat pump would, so treat them as a bridge of days and not a way to finish the winter.
Do you repair ductless mini-splits in Caledon farmhouses?
Yes. Wall-mounted heads and multi-zone systems have their own fault list: a clogged condensate line that drips down the wall, an indoor fan motor, and communication errors between the head and the outdoor inverter. Note the code flashing on the head or the remote before you call. Mitsubishi, Daikin and Fujitsu each use their own tables, and the code narrows the fault before the truck leaves Burlington.
How do I stop the same heat pump failure next winter?
Most repeat calls trace back to three things: an outdoor unit sitting too low in the snow, a coil that was never cleaned, and power events. Raising the unit on a proper stand, a fall check of the defrost system and surge protection at the outdoor disconnect address all three. Heat pump maintenance in Caledon covers what the fall visit includes.
