A meticulous cleaning operation by AirGreen
At AirGreen , we recently performed a complete cleaning of a Zephyr heat pump installed in Sainte-Anne-de-Bellevue , in the West Island of Montreal. The unit, positioned outdoors against a wooden wall, showed the classic signs of dirt and moisture buildup due to the surrounding vegetation and its proximity to the ground. This type of setup, common in residential areas surrounded by greenery, requires rigorous maintenance to preserve the system's performance.
Initial diagnosis: humidity, debris, and reduced efficiency
Before our intervention, the client contacted us after noticing a decrease in heating efficiency and increased noise coming from the outdoor unit. Upon examining the heat pump, our technician found:
-
An accumulation of leaves and soil under the base of the device, limiting air circulation.
-
Condenser fins covered with a light organic film (dust, moisture, pollen).
-
Traces of stagnant moisture on the metal base, which can eventually cause corrosion.
-
Some climbing plants near the fan may obstruct ventilation.
These conditions, although common, have a cumulative effect: they reduce the heat exchange capacity of the system and increase electrical consumption.
Complete step-by-step cleaning
1. Preparation and securing
Before any work began, we disconnected the heat pump's power supply and cleared the work area . Plants and leaves around the unit were carefully removed, ensuring a clear space of at least 60 cm around the condenser.
2. Hood removal and internal inspection
We then removed the top cover and the fan guard . This allowed us to inspect the condenser fins, wiring, and motor mounts. No damage was found, but a thin layer of organic deposit covered the surface of the coil.
3. Cleaning the coil and fins
Using a biodegradable cleaning product specifically designed for HVAC heat exchangers , we sprayed the coil over its entire surface. After a ten-minute contact time, rinsing with clean water at low pressure removed the ingrained dirt without damaging the fins.
4. Cleaning the fan and the drainage tray
The fan was manually cleaned to remove accumulated dust and micro-debris. The drainage tray was then checked to ensure proper drainage of condensation, a crucial point to prevent mold or winter freezing.
5. Checking the metal support
Finally, we cleaned the galvanized steel support and applied a light anti-corrosion treatment to extend its lifespan. This step is often overlooked, but it directly contributes to the stability and safety of the installation.
Results: restored performance and durability
After reassembly and functional testing, the Zephyr heat pump regained optimal airflow and quiet operation . The customer noted a significant improvement in heating and a reduction in outside noise . By cleaning the fins and clearing the area around the unit, we also improved heat dissipation, thus reducing the compressor load.
Why regular maintenance is essential
Annual cleaning of outdoor heat pumps is essential, especially in areas with dense vegetation. It helps to:
-
Preserve the energy performance of the system.
-
Reduce electricity consumption .
-
Extend the lifespan of the compressor and electronic components.
-
Prevent premature breakage due to corrosion or overheating.
At AirGreen, we exclusively use environmentally friendly products and methods that comply with manufacturers' recommendations, such as Zephyr. Each cleaning is accompanied by a complete check of overall operation to detect any signs of failure before they become costly to repair.
Conclusion: Peace of mind guaranteed by AirGreen
Thanks to this service, the client's outdoor heat pump is ready to face the coming seasons, ensuring comfort, efficiency, and peace of mind. This type of preventative maintenance perfectly illustrates our approach: protecting your HVAC investments while maximizing your indoor comfort .
