Heat pump repair in Saint-Laurent
Saint-Laurent's housing mixes apartments in towers and low-rise buildings with row, semi-detached and detached homes, so heat pumps range from ducted central systems in houses to ductless units in apartments. Cold-climate models are built for Quebec winters. JCD repairs all brands and also services commercial rooftop units for Saint-Laurent's businesses.

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 Saint-Laurent, 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.
-
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.
-
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.

LOCAL CONSIDERATIONS · Saint-Laurent
What is different about repairs here
- For exclusively residential buildings the borough requires no permit; for commercial, industrial and institutional buildings a 524 $ permit per unit applies. The zoning bylaw applies to both.
- Detached, semi-detached and row houses are about a quarter of homes (25.6%) and are the likeliest to have ducted central heat pumps. Apartments typically use ductless units.
- Almost 30% of homes are in buildings of five storeys or more, where outdoor unit placement and access depend on the building's management.
