Heat Pump Repair and Service Call in Blainville
At AirGreen, we specialize in repairing central heat pumps and other HVAC systems. Recently, we performed a service call to troubleshoot a Carrier central heat pump in Blainville, where we solved a technical issue affecting the unit’s operation. This article outlines the diagnostic and repair process, as well as how our technicians restored the comfort and efficiency of our client’s system.
The Initial Problem with the Carrier Central Heat Pump
The customer contacted us due to a malfunction in their Carrier central heat pump system. After a thorough diagnosis, it became clear that one of the system's key components, a defective compressor, was causing the failure of the outdoor unit. The early signs included a significant drop in performance, which led the client to notice a loss of heating during the winter—a period when the central heat pump is essential for maintaining a comfortable, steady temperature indoors.
The Diagnosis: Identifying the Source of the Problem
Upon arriving on site, our technicians began with a complete inspection of the system. The Carrier central heat pump, which is installed on the flat roof of the house, was visible and accessible. After checking the electrical connections and refrigerant levels, it quickly became apparent that the compressor in the outdoor unit was the issue. This kind of problem can sometimes be caused by premature wear or wiring issues, which requires careful repair.
The Solution: Replacing the Compressor in the Carrier Heat Pump
Once we confirmed that the compressor was at fault, we recommended replacing it with a new, compatible, and high-quality compressor to ensure the Carrier system would perform optimally in the long run. Replacing the compressor required temporarily shutting off the unit’s power supply to ensure the safety of the process.
Our technicians carefully disconnected the old compressor and installed the new model. Before reconnecting the unit, we conducted a refrigerant leak test and adjusted the necessary levels to guarantee optimal efficiency. Once the replacement was complete, we tested the heat pump’s performance to ensure everything was working perfectly.
Results After the Repair
After the repair, the Carrier central heat pump was back to full functionality, and the client immediately noticed an improvement in the system’s efficiency. Indoor comfort was restored, and energy consumption was reduced thanks to a heat pump that was now perfectly calibrated. We also advised the client to schedule regular maintenance to prolong the life of the equipment.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
It captures or rejects heat outside. It sits on a level base, above the snow, with free space all around.
The insulated refrigerant lines enter the house through a sealed opening and run to the indoor coil.
A shut-off switch near the outdoor unit isolates it safely for service.
Sitting on the indoor module, it moves heat between the house air and the refrigerant.
Electric furnace or air handler: its fan pushes air through the ducts. The electric backup takes over in extreme cold.
Supply ducts bring air to the rooms; returns bring it back to the unit. Their condition matters as much as the unit's.
It protects the coil and the fan. A dirty filter cuts airflow, so it gets checked regularly.
It runs the heat pump and the backup heat. It must be compatible with the installed system.
