Heat pump repair in Ahuntsic
In Ahuntsic, heat pumps go into plex apartments as ductless heads and into twin and detached houses as ducted systems that work with the existing furnace or replace it. Cold-climate models run through Montreal winters, but a unit that ices up, short-cycles or stops heating needs a diagnosis. JCD repairs all brands of heat pump.

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 Ahuntsic, 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 outdoor coil stays covered in ice
A light frost that clears after a defrost cycle is normal. A coil that stays encased in ice for hours is not.
-
The heat pump starts and stops every few minutes
Short cycles wear the compressor and leave some rooms warmer than others.

LOCAL CONSIDERATIONS · Ahuntsic
What is different about repairs here
- A front-balcony unit needs a building of 4 or more dwellings: one unit per dwelling, hidden from the street, 40 x 75 x 100 cm at most.
- On a balcony, the unit must be at least 2 m horizontally from any neighbour's window or balcony, and the lines to the building cannot exceed 0.5 m.
- Rear and side yards need at least 1 m from the lot line, and the front yard is not allowed. Ask the permit counter about corner lots and heritage sectors.
