Heat pump repair in Westmount
Most Westmount households live in semi-detached or row houses, condos and rented apartments, since only 13% are in single-detached houses. A heat pump here often has to fit a narrow lot or a flat roof, stay 2 m from every property line and stay out of sight from the street. JCD repairs all brands of heat pumps, ducted or 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 Westmount, 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.
-
The heat pump starts and stops every few minutes
Short cycles wear the compressor and leave some rooms warmer than others.

LOCAL CONSIDERATIONS · Westmount
What is different about repairs here
- By-law 1303 (s. 6.10) requires 2 m from every property line and no view of the unit from the street, so vegetation or an enclosure is part of most placements.
- Noise by-law 1387 sets limits where neighbours hear the unit: 40 dBA by day and 35 dBA at night in a bedroom, 50 and 45 dBA on a patio.
- On attached and semi-detached homes, by-law 1387 caps the cooling capacity of added units and requires spring-rail vibration mounts for units on the roof.
