Heat pump repair in Vaudreuil-Dorion

Because 54% of Vaudreuil-Dorion’s dwellings date from 2001 on, a heat pump here is more likely to be paired with a newer furnace or air handler than with an original 1960s unit, and the 30% of dwellings in apartment buildings under 5 storeys lean on ductless equipment. JCD repairs heat pumps of all brands, including refrigerant leaks, reversing valves and defrost faults.

Homes and buildings in Vaudreuil-Dorion

Of 16,715 occupied dwellings in 2021, 53% are single-detached houses and 30% are apartments in buildings under 5 storeys. A quarter were built since 2011, and 9.7% date from 1960 or earlier. Newer buildings have lower heating loads and tighter envelopes, which favours a right-sized cold-climate heat pump, while the older houses need the same duct and furnace checks as any older home.

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 · Vaudreuil-Dorion

What is different about repairs here

  • By-law 1872 requires 3 m from side and rear lot lines, or 1.5 m with an opaque screen 1.2 m high and noise under 50 dB at the lot line.
  • Attached single-family and horizontal multi-family homes have no minimum distance on the party-wall side in the rear yard, which helps on tighter lots.
  • In multi-family buildings, a front-yard unit is allowed only on a balcony and must be hidden from the street.

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