First-Generation Heat Pumps in Newer Markham Builds
Cornell, Greensborough and Wismer Commons were built out during the first wave of residential heat pump adoption, so a good number of Markham homes are running early equipment that is now reaching the age where control components fail. The compressors are frequently fine. It is the boards, sensors and communication between the indoor and outdoor units that go.
We read the fault code rather than resetting the unit and hoping, and we check parts availability before recommending a repair. Early two-stage and communicating systems used control boards that are getting difficult to source, and there is no point quoting you a repair that depends on a part nobody stocks in February.

Frequently Asked Questions about Heat Pump Repair in Markham
Do you repair heat pumps in the winter in Markham?
Yes. Heat pumps run year-round, so we repair them in every season across Markham, including same-day service for a no-heat call in the cold.
Why is my heat pump icing up in Markham?
Light frost is normal and clears on the defrost cycle. Heavy ice that does not clear points to a defrost, refrigerant, or airflow fault, which we can diagnose same-day in Markham.
Do you service cold-climate and ductless heat pumps?
Yes. Our TSSA-certified technicians service ducted cold-climate, ductless mini-split, and hybrid gas-plus-heat-pump systems.
What does heat pump repair cost?
The $129 diagnostic is applied to the repair. Most heat pump repairs land between $150 and $700, quoted flat before work begins.
My Markham heat pump throws an error and stops. Is the compressor gone?
Usually not. On early communicating systems the most common failures are the control board, a sensor, or the communication link between the indoor and outdoor units. All of those lock the unit out in a way that looks like a major failure. We read the stored fault code first, which normally tells us within minutes whether you are looking at a component or a compressor.
Can you still get parts for an early heat pump?
Sometimes, and we check before quoting rather than after. Control boards and reversing valves for first-generation residential units are increasingly hard to source. If the part is not realistically obtainable we will tell you that and price replacement honestly, rather than leaving you without heat while an order sits on backlog.
Is it worth repairing a first-generation heat pump?
It depends on the part and on what else is ageing. A sensor or a fan motor is straightforward and buys real years. A control board that is hard to source, on a unit already past twelve years, is usually money spent postponing a replacement by a season. We give you the parts availability and the honest recommendation before you decide.
Do you service all Markham neighbourhoods?
Yes. We cover Unionville, Cornell, Berczy Village, Markham Village, Milliken Mills, Thornhill, Cathedraltown, and every Markham community with same-day and emergency service.
