Repair of an Everest wall-mounted heat pump in Rosemère

A precision intervention by AirGreen on the North Shore

At AirGreen , every service call is an opportunity to demonstrate our HVAC repair expertise and our commitment to our customers' comfort. Recently, our team traveled to Rosemère , on the North Shore, to address a problem with an Everest wall-mounted heat pump that had been installed for several years on a red brick exterior wall typical of single-family homes in the area.

Diagnosis: loss of performance and abnormal noise

The customer contacted us after noticing that their system was no longer heating efficiently , despite a compressor that appeared to be working. Additionally, an intermittent metallic noise was coming from the outdoor unit, accompanied by a slight vibration transmitted to the wall bracket. These symptoms, common in aging systems, could indicate:

  • A lack of refrigerant (potential leak on the copper line or at the service valves);

  • A worn fan motor ;

  • Or an electrical problem on the external control board.

Our certified technicians therefore carried out a complete diagnosis , following the proven AirGreen procedure:

  1. Checking the refrigerant gas pressure (R-410A in this case).

  2. Visual inspection of welds and flare connections.

  3. Electrical testing of starting components.

  4. Mechanical inspection of the fan and bearings.

Diagnostic result: leak and defective engine

After an hour of methodical inspection, two distinct problems were identified:

  • A micro-leak of refrigerant at the suction connection;

  • An outdoor fan motor whose bearing was starting to seize up.

These two failures combined perfectly explained the loss of power and the noise observed.

Repair: efficiency and durability

Our technicians began work in accordance with CSA standards and AirGreen procedures:

  • Repair of the connection by re-welding with silver solder and leak test under nitrogen.

  • Replaced the fan motor with an original Everest compatible model.

  • Complete vacuuming of the refrigeration circuit before recharging to the exact weight (measured to the nearest gram).

  • Complete functional test and measurement of high and low pressures.

After the repair was completed, the compressor restarted without abnormal noise and the indoor discharge temperature quickly reached nominal performance.

Regained comfort and a reassured customer

Within minutes of restarting, the residence was back to optimal comfort. The client particularly appreciated the speed of the response (the service was completed in a single visit) and the transparency of the diagnosis : each step was clearly explained, with supporting photos.

At AirGreen, we want our customers to understand not only what we repair , but also why and how we do it . This approach promotes confidence and durability in the HVAC systems we maintain.

Maintenance tips for Everest wall-mounted heat pumps

To extend the life of your heat pump, our technician recommended:

  • A complete cleaning of the outdoor coil twice a year (spring and fall).

  • An annual check of the refrigerant charge .

  • AirGreen preventive maintenance every fall before the heating season.

  • And above all, prevent snow or ice from accumulating around the compressor.
