Repair of a Goodman wall-mounted heat pump in Saint-Constant

When nature meets technology: a service call in the heart of Saint-Constant

In Saint-Constant, on Montreal's South Shore, a customer contacted us about a problem with a Goodman wall-mounted heat pump installed on the exterior wall of a charming wooden house. The unit, although robust, was showing signs of weakness: cooling was inefficient and the outdoor unit was making an unusual vibrating noise .

At AirGreen , we know that even the most reliable appliances require professional attention, especially in environments where nature is omnipresent—like here, where maple branches brush the facade and surround the compressor.


Diagnosis: when vegetation affects the performance of a heat pump

Our technician quickly arrived on site for a complete diagnosis. Within the first few minutes, several observations were made:

  • The Goodman condenser was partially blocked by leaves and twigs.

  • The minimum clearance space required around the unit (usually 60 cm) was not respected.

  • The drain pipe was slightly bent, restricting the proper flow of condensate.

  • Finally, a buildup of dirt on the condenser fins significantly reduced heat transfer.

After turning off the power and securing the area, our technician removed the front grille for a thorough cleaning and performed a refrigerant pressure check . No leaks were detected, but the compressor was having to work excessively to compensate for the loss of efficiency due to fouling.


Intervention: cleaning, realignment and complete re-leveling

The intervention was carried out in three methodical stages:

  1. Complete cleaning of the condenser and fins using a Goodman approved biodegradable product, ensuring optimal heat dissipation.

  2. Realignment of the wiring and insulated conduit , correctly replaced against the wall to avoid any contact with humidity or plants.

  3. Electrical check : tightening of the main terminal block, continuity test, and validation of the supply voltage (240 V stable).

During the restart, the heat pump resumed its quiet and smooth operation, with perfectly balanced pressure according to the manufacturer's specifications.


Result: efficiency restored and preventive maintenance recommended

As soon as our intervention was over, the client immediately noticed the difference:

  • Stable and uniform temperature inside the house.

  • Operational silence restored.

  • Reduction in electricity consumption , thanks to the reduction of the load on the compressor.

We recommended to the owner an annual preventive maintenance , including:

  • Spring cleaning of the coils .

  • A check of the plant clearance around the unit.

  • Test the airflow and electrical connections before each heating or cooling season.

These simple measures not only ensure the longevity of the heat pump, but also provide the customer with peace of mind throughout the year.
