Heat pump repair in Notre-Dame-de-Grâce
In the Côte-des-Neiges–Notre-Dame-de-Grâce borough, 67% of occupied dwellings are in duplexes or apartment buildings under five storeys, so a heat pump often has to fit a plex or low-rise building, and the borough limits how close a unit can sit to the lot line. Where a building has no ducts, ductless heads are the usual choice. JCD repairs all brands of cold-climate and standard heat pumps.
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 Notre-Dame-de-Grâce, 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 heat pump starts and stops every few minutes
Short cycles wear the compressor and leave some rooms warmer than others.
-
Ice on the refrigerant line in cooling mode
Frost forms on the insulated line or the indoor coil while the heat pump is cooling.

LOCAL CONSIDERATIONS · Notre-Dame-de-Grâce
What is different about repairs here
- Outdoor units are banned on the front of a building, so repairs and replacements happen in side or rear yards, within the borough's size limits near lot lines.
- A unit under 1 m from a lot line can be at most 40 cm deep, 75 cm high and 100 cm wide; larger units need more room.
- Properties in the Mont-Royal historic and natural district have extra conditions, and corner lots must be checked with the borough's permit counter.
