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.

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
  • Ice on the refrigerant line in cooling mode

    Frost forms on the insulated line or the indoor coil while the heat pump is cooling.

    Possible causesDirty filter or coilRestricted airflowLow refrigerant
  • The heat pump starts and stops every few minutes

    Short cycles wear the compressor and leave some rooms warmer than others.

Repair or replace?

Under twelve years and a first major fault: repair, almost always. Over fifteen years, or a second major failure inside two seasons: replacement is worth considering.

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.

If the coil is frosted solid or the line is icing over, shut the system off and call rather than letting it run.
