Heat pump repair in Île-des-Sœurs
Heat pumps in Île-des-Sœurs towers and condos are typically ductless, with the outdoor unit on a balcony or in a shared area. Cold-climate models are built for Quebec winters. JCD repairs all brands, including head control boards, drain pumps, iced coils, refrigerant leaks and failed fan motors, and arranges building access with management.

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 Île-des-Sœurs, 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 on Île-des-Sœurs
The island is part of Verdun borough, and its housing is apartment towers and condo developments built since the Champlain Bridge opened in 1962. Condo owners may need syndicate authorization before installing or changing an outdoor unit, and outdoor units and copper lines often cross common areas, so work is usually arranged with management or the syndicate.

LOCAL CONSIDERATIONS · Île-des-Sœurs
What is different about repairs here
- Removable air conditioners are banned on the island and permanent units need a Verdun permit, so check with the borough before relocating an outdoor unit.
- In condo buildings, outdoor units and copper lines often cross common areas. Repairs may need syndicate or management approval and a scheduled access time.
- Under Verdun's rules, a balcony unit may not rise above the railing and must be at least 1 m from lot lines. Confirm your building's own rules as well.
