Heat pump repair in Cartierville
In Cartierville, a ducted heat pump can often use the duct system already in a postwar house, while apartment units take ductless heads. Cold-climate models run through Montreal winters, but ice on the outdoor coil, short-cycling or a loss of heat still needs a technician. JCD repairs all brands of heat pump, ducted and ductless.

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 Cartierville, 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.
-
Ice on the refrigerant line in cooling mode
Frost forms on the insulated line or the indoor coil while the heat pump is cooling.
-
Outdoor unit hums but the fan does not spin
You can hear the compressor trying to start while the top fan sits still. Turn it off: the compressor is overheating.

LOCAL CONSIDERATIONS · Cartierville
What is different about repairs here
- The unit goes in a side or rear yard at least 1 m from the lot line. A permanent unit is not allowed in the front yard.
- Corner lots follow special criteria, so ask the borough permit counter before moving or replacing an outdoor unit on a street corner.
- If the property is in a heritage, significant or natural sector, the borough refers the request to its permit counter. Ask before you book the work.
