Heat pump repair in Dorval
Dorval's mix of 1950s houses and low-rise apartment buildings means two kinds of heat pump repair: central ducted systems tied to an older furnace, and ductless units serving a single apartment. A heat pump works hardest in a Montréal January, and a worn defrost board or reversing valve usually shows up then, as ice on the coil or air that never warms. JCD repairs all brands of heat pump in Dorval and traces the fault outdoors or inside.
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 Dorval, 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.
-
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.
-
The breaker trips when the heat pump starts
The heat pump trips its breaker at start-up or after a few minutes. Do not keep resetting it.
-
The outdoor unit rattles or screeches
A new metallic, grinding or high-pitched noise comes from the outdoor unit.
-
The heat pump starts and stops every few minutes
Short cycles wear the compressor and leave some rooms warmer than others.

Homes and buildings in Dorval
In the 2021 census, 46% of Dorval households live in single-detached houses and 36% live in apartment buildings under 5 storeys. About 70% of homes were built before 1981, and 40% of households rent. Houses of that age often need a duct and furnace check before a heat pump goes in, and apartment units without ductwork usually point to ductless equipment.

LOCAL CONSIDERATIONS · Dorval
What is different about repairs here
- In residential zones the by-law keeps outdoor units out of the front yard, so repair and replacement happen in the side or rear yard rather than from the street.
- In the Vieux-Village, central urban and commercial zones the by-law limits outdoor units to the rear yard, which decides where a replacement unit can be placed.
- In residential neighbourhoods a heating oil tank must be indoors, not buried, and no larger than 910 litres, which matters when an oil furnace gives way to a heat pump.
