Heat pump repair in Downtown Montreal
In downtown towers a heat pump is often a ductless or in-suite system, with little or no yard for an outdoor unit. Ville-Marie bans units in front yards and on front balconies and sets a roof setback of twice the unit's height. JCD repairs all brands, arranges access with building management and works on condo systems and commercial rooftop equipment.

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 Downtown Montreal, 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.
-
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.

Homes and buildings in Downtown Montreal
Downtown is part of the Ville-Marie borough, where 97.6% of occupied dwellings are apartments and 56.9% are in buildings of five storeys or more. Montreal's assessment roll shows 46.5% of the borough's dwelling units in buildings built since 2001. A tower has little or no yard, so outdoor equipment goes on a roof or inside the building, and access is arranged with the building manager.

LOCAL CONSIDERATIONS · Downtown Montreal
What is different about repairs here
- Ville-Marie bans permanent units in a front yard and on a balcony on the front of a building, which rules out the simplest placement on street-facing sides of condo towers.
- On a flat roof, the outdoor unit must be set back from the façade by twice its height, and an acoustic screen may be required.
- Towers rarely have a ground-level yard, so work on rooftop equipment is scheduled with the building manager and, in condos, the condo board.
