An essential cleaning intervention to restore the performance and cleanliness of an outdoor unit
At AirGreen , we know that regular maintenance of your HVAC system is not just about comfort, but also about durability and energy efficiency. During a recent service call in Sainte-Dorothée, Laval , our team was tasked with performing a complete cleaning of a Fujitsu Halcyon Series HFI wall-mounted heat pump .
Symptoms observed before our intervention
The customer had noticed that their heat pump was producing less cool air than usual and that the outdoor unit appeared very dirty. Upon inspecting the system, we found:
-
A significant accumulation of mold and dust on the grille and fins.
-
Green and black traces of organic dirt linked to humidity.
-
Intermittent water leaks caused by a partially blocked drain .
-
A decrease in energy efficiency , confirming that the heat pump had to work harder to maintain the desired temperature.
Steps in our professional cleaning process
Our team carried out a methodical and safe cleaning , respecting the recommendations of the manufacturer Fujitsu:
1. Power off and complete inspection
Before any work began, we disconnected the power supply and checked the condition of the connections, insulation, and refrigeration lines . This ensures safe working practices and prevents any damage.
2. Partial disassembly of the outer casing
The front cover and protective grille were removed to expose the condenser fins and fan turbine . This step is crucial for accessing areas often overlooked during a simple surface cleaning.
3. Application of a biodegradable cleaner
We used an environmentally friendly cleaning product , formulated to dissolve grease, dust, and biological residues without damaging metal surfaces. After a short application time, a rinse with a jet of fresh water removed all the accumulated impurities.
4. Clean the drain and check the water flow
The condensation drain was cleared using a low-pressure pump and then tested to ensure proper drainage. This prevents water from pooling, a common cause of unpleasant odors and premature corrosion.
5. Antibacterial disinfection and final rinse
To prevent mold growth, we applied an antibacterial treatment to the internal surfaces. Finally, a thorough flush restored the heat pump to its original appearance and efficiency.
Result: a high-performing and durable unit
Once the cleaning was complete, we restarted the system:
-
The airflow has improved significantly.
-
The operating noise has decreased.
-
Energy efficiency has returned to normal.
-
And most importantly, the quality of the blown air has become healthy and free of odors.
