The Service Call: Refrigerant Leak and System Malfunction
Upon receiving the service call from a client in Longueuil, we were informed that the central heat pump Rheem was no longer providing heat. After assessing the issue, it quickly became clear that a refrigerant leak was one of the main causes of this failure.

Checking the integrity of the pipes and connections: Each connection was tested to detect refrigerant leaks. A specialized tool was used during this step to detect any refrigerant leaks in the ducts.
-
Repairing the leak: Once the leak was located, our technician replaced the faulty seals and carried out the necessary repairs to ensure the system was airtight.
-
Recharging the refrigerant levels: After repairing the leak, we recharged the system with the appropriate refrigerant and checked that the levels were in accordance with the manufacturer's specifications.
-
Improving the duct insulation: To prevent future energy losses, the duct insulation was reinforced, with special attention given to the connections.
Results: Returning to Optimal Performance
After completing the repair, the Rheem central heat pump regained optimal performance, ensuring ideal thermal comfort for our client in Longueuil.
