Heat pump repair in Côte-Saint-Luc
In Côte-Saint-Luc, heat pumps fit two settings: ducted central systems in houses, and ductless units in condo and rental apartments, where 53% of homes are in buildings of five storeys or more. Cold-climate models are built for Quebec winters. JCD repairs all brands, including reversing valves, defrost boards, refrigerant leaks and failed fan motors, for either setup.

The most common heat pump failures are a refrigerant leak, a failed reversing valve, a defrost board fault and an iced-over outdoor coil. Same-day emergency service in Côte-Saint-Luc, seven days a week: call 514-696-4629.
Common heat pump problems we repair
Mention the symptom when you call so our team can prepare.

-
Water drips from a wall-mounted head
Water runs down the wall under a ductless indoor unit, most often in cooling season.
-
A ductless head blinks or shows an error code
The indoor unit stops and its light flashes a pattern or a code. Note it before you call: it tells the technician where to start.
-
Cool air in heating mode
The heat pump runs, but the air from the vents is lukewarm or cool while the thermostat calls for heat.
-
The breaker trips when the heat pump starts
The heat pump trips its breaker at start-up or after a few minutes. Do not keep resetting it.

Only 10.4% are in buildings under five storeys, while 14.6% are detached and 11.1% semi-detached. About half of households rent.

LOCAL CONSIDERATIONS · Côte-Saint-Luc
What is different about repairs here
- The zoning by-law permits compressors in side and rear yards but not the front yard, which limits where a failed outdoor unit can be moved.
- The city's guide says replacing a heat pump needs no permit, but modifying a heating or cooling system does. Confirm with the permits office at 514 485-6800, option 2.
- In condo buildings, the city asks for a condo association letter for interior renovations, and outdoor units and lines often cross common areas, so access is arranged ahead of time.
