Essential maintenance to ensure the system's performance and longevity
At AirGreen , we know how essential a well-maintained wall-mounted heat pump is for ensuring optimal comfort, especially during the hot summers and humid winters of the Montreal area. Recently, our team travelled to Sainte-Anne-de-Bellevue , a quiet residential neighbourhood in the West Island, to perform a complete cleaning of an outdoor wall-mounted heat pump unit installed on a red brick wall.
Initial state: accumulated dirt and overgrown vegetation
Upon arrival, our technician quickly identified several problems:
-
Significant accumulation of dust and pollen on the unit's fins.
-
Presence of climbing vegetation around the base, which may obstruct air circulation.
-
Discoloration of the coil indicating prolonged fouling.
-
Limited space between the wall and the fence , restricting ventilation.
These conditions compromised the system's energy efficiency and could lead to compressor overheating or premature fan wear.
Our service: deep cleaning and refurbishment
Step 1 – Securing and Inspection
Before any handling, the device was unplugged and secured . We then carried out a complete visual inspection of the fins, casing and electrical wiring to detect any signs of wear or oxidation.
Step 2 – Clearing the area
We carefully cleared the surrounding vegetation to open up the ventilation area. Good airflow is crucial to avoid excessively long operating cycles and increased energy consumption.
Step 3 – Gentle high-pressure cleaning
Using a low-pressure cleaner and a biodegradable cleaning product , we washed:
-
The heat exchanger fins to remove dust, pollen and grease.
-
The protective grille and the fan are often clogged with insects and plant debris.
-
The condensation tray and the mounting brackets , which often accumulate dirt and corrosion.
Step 4 – Rinse and check
A thorough rinse with clean water was performed to remove all cleaning product residue. After drying, we reconnected and tested the heat pump in cooling mode to check the gas pressure, the airflow temperature, and the compressor noise.
Results: restored effectiveness and immediate comfort
After cleaning:
-
The airflow has returned to optimal levels .
-
The unit's noise level has decreased .
-
The outlet temperature has stabilized, indicating efficient heat exchange.
-
The customer immediately noticed a faster cooling effect inside.
We also advised the owner to have a full annual service , ideally before summer, to prevent any degradation in performance and to prolong the life of the system.
