Repair
Get your heat pump repaired quickly
Heat pumps help maintain the ideal temperature in your home, regardless of the temperature outside—they cool your home in the summer and heat it in the winter using a single unit installed outdoors.
Air duct cleaning, heat pump furnace repair, heating system repair, and air conditioner repair are just a few examples of the repair services we offer.
If you're experiencing any of the above issues, contact JLM Air Conditioning for heat pump repair services. Our team will perform a complete diagnostic of your system and, depending on the issue and unit, may even complete the repair the same day!
Our technicians are available 24/7 to serve the North Shore of Montreal, specifically the Laurentians, Lanaudière, and Laval regions. Use our service request form to schedule a heat pump repair appointment today.

A faulty heat pump can result from a myriad of issues. Here are three commonly reported problems:
- Frozen heat pump
In winter, a frozen heat pump can be the result of a defrost cycle not working, a faulty outdoor fan, a low refrigerant charge, a physical blockage of the outdoor unit, or water falling on the unit and causing it to freeze.
A frozen heat pump won't heat and, worse, can cause serious damage or failure if left to run. During the summer, freezing can occur on the indoor coil or the copper line leading to the compressor due to low refrigerant, a clogged air filter, or extremely dirty coils.
2. Constant operation
In winter, check the thermostat to make sure the heat pump isn't set to cool. Other reasons could include a frozen outdoor coil, a compressor problem, or a dirty and poorly maintained unit. In summer, check that the system isn't in heating mode. Other problems could include triple-digit temperatures, refrigerant leaks, or a dirty/clogged coil or air filter.
3. Cold air in heating mode
Check that the thermostat has not been set to AC/cool mode. If it hasn't, the problem could be a low refrigerant charge or a problem with the reversing valve or compressor. It could also be the result of poor maintenance and a dirty or clogged coil.

“I used Climatisation JLM to identify the problem with my existing air conditioner. Although it wasn't a brand they sell, they still agreed to help us diagnose the problem and find solutions to try to avoid replacement by repair. Excellent quality service, these people know what they're doing!”
