Heat pump repair in Lachine
Most Lachine homes are apartments in plexes and small buildings, where one ductless heat pump usually serves one unit. Detached houses, 14.2% of the stock, are more likely to have a ducted central system. Cold-climate heat pumps are built for Quebec winters, and JCD repairs all brands: refrigerant leaks, reversing valves, defrost boards, iced coils and failed fan motors.
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 Lachine, 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.
-
Backup heat runs far more than it used to
The backup heat comes on in mild weather, or the heating bill climbs while the heat pump seems to run.
