Heat pump repair in Cartierville

In Cartierville, a ducted heat pump can often use the duct system already in a postwar house, while apartment units take ductless heads. Cold-climate models run through Montreal winters, but ice on the outdoor coil, short-cycling or a loss of heat still needs a technician. JCD repairs all brands of heat pump, ducted and 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
  • Outdoor unit hums but the fan does not spin

    You can hear the compressor trying to start while the top fan sits still. Turn it off: the compressor is overheating.

Homes and buildings in Cartierville

Borough-wide in 2016, 9% of dwellings were detached houses, 37% were built in 1960 or earlier and 33% from 1961 to 1980. Real-estate data point to many bungalows and houses from the 1950s and 1960s, especially along boulevard Gouin. Houses of that age typically have ducts that a ducted heat pump can use, while apartments usually take ductless heads.

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 · Cartierville

What is different about repairs here

  • The unit goes in a side or rear yard at least 1 m from the lot line. A permanent unit is not allowed in the front yard.
  • Corner lots follow special criteria, so ask the borough permit counter before moving or replacing an outdoor unit on a street corner.
  • If the property is in a heritage, significant or natural sector, the borough refers the request to its permit counter. Ask before you book the work.
