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.

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.

    Possible causesBlocked condensate lineCondensate pumpHead not level
  • 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.

    Possible causesSensor faultCommunication wiringControl board
  • 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.

    Possible causesDefrost boardDefrost sensorLow refrigerant
  • 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.
Heat pump down in Île-des-Sœurs?
If the coil is frosted solid or the line is icing over, shut the system off and call rather than letting it run.
