When a breakdown occurs in the heat: our rapid intervention in Sainte-Catherine
At AirGreen , we know that a wall-mounted heat pump plays an essential role in the daily comfort of families, especially during the hot summers on the South Shore . Recently, we were called to assist a client in Sainte-Catherine whose Turcotte wall-mounted heat pump was no longer functioning properly. The system, installed on a typical single-family brick wall, was showing signs of weakness in the outdoor fan.
Accurate diagnosis: an external fan with reduced efficiency
Upon our arrival, we carried out a complete assessment of the outdoor condenser . The customer had reported an unusual noise and a noticeable decrease in the flow of cold air inside. After opening the panel, our technician noted:
-
A slightly unbalanced fan , causing abnormal vibrations.
-
A buildup of dust and debris on the grille, reducing airflow.
-
Partially oxidized power wiring , a potential source of short circuit.
We also tested the refrigerant pressure , which was found to be normal, ruling out an R-410A refrigerant leak.
System repair and refurbishment
Our team undertook a complete overhaul of the outdoor module :
-
Complete cleaning of the condenser fins and ventilation housing.
-
Rebalancing of the fan and replacement of the engine silent block.
-
Repair of electrical wiring , with replacement of oxidized connectors.
-
Application of an anti-corrosion treatment to exposed metal parts.
This series of interventions allowed the heat pump to regain its optimal performance , while considerably reducing the perceived noise level.
Performance restored and customer satisfied
After powering up, we observed an immediate improvement in cold airflow and a stable interior temperature within 15 minutes. The customer appreciated our transparent approach: each step was explained to him, and the replaced parts were shown to him before the new ones were installed.
At AirGreen, we place particular importance on the long-term reliability of each system. In this case, we recommended a complete annual maintenance program that included coil cleaning, compressor inspection, and condensate monitoring—simple steps that extend the life of a wall-mounted heat pump by several years.
Some tips to prevent this type of breakdown
We took advantage of our visit to share some useful tips with the owner:
-
Clean the internal filter every month during the warm season.
-
Clear the area around the outdoor unit , especially of leaves and dust.
-
Avoid obstructing the fan grille with objects or decorations.
-
Schedule a professional interview before each summer to detect anomalies early.
These simple actions ensure quiet, energy-efficient and trouble-free operation.
