Heat pump repair in Senneville
Senneville’s older single-detached houses can take a heat pump alongside the existing furnace, or a ductless unit in rooms without duct runs. JCD repairs heat pumps of all brands, including refrigerant leaks, reversing valves, defrost boards and iced outdoor coils. In a house built before 1961, a heat pump that fails in January can leave the old furnace carrying the whole load, so we diagnose it before the next cold stretch.

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 Senneville, 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.
-
Cool air in heating mode
The heat pump runs, but the air from the vents is lukewarm or cool while the thermostat calls for heat.
-
Ice on the refrigerant line in cooling mode
Frost forms on the insulated line or the indoor coil while the heat pump is cooling.
-
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 Senneville
In the 2021 census, 310 of Senneville’s 350 occupied dwellings are single-detached houses, and 81% of households own their home. About 210 dwellings were built in 1960 or earlier, including 60 from 1920 or before, and only 10 since 2016 (counts are rounded to the nearest 5). Houses this old may have ductwork sized for earlier equipment, so we check airflow before recommending a replacement or a heat pump.

LOCAL CONSIDERATIONS · Senneville
What is different about repairs here
- By-law 448 bans outdoor units from the front yard. Side and rear yards work, at least 2 m from the lot line with a screen or 3 m without.
- A unit in a side yard must be hidden from the street by opaque landscaping, so we plan the location to keep it reachable for service.
- The village requires a certificate of authorization to install or replace a heat pump or air conditioner, so confirm it before a swap-out.
