A complete service to restore performance and air quality
At AirGreen , we regularly perform cleaning services for wall-mounted heat pumps throughout the Montreal, Laval, and North Shore region. One of our recent service calls in Sainte-Thérèse perfectly illustrates the importance of regular maintenance, even for reputable equipment like Fujitsu .
In this single-family home, the client noticed that her system was blowing less cold air than usual and that a slight odor was emitted when starting up. These symptoms are typical of a buildup of dust and dirt in the filters and evaporator .
Initial diagnosis: saturated filters and reduced airflow
Upon opening the cover of the indoor unit, our technicians found air filters clogged with a thick layer of dust , seriously limiting airflow.
This accumulation was harmful on several levels:
-
Reduced energy efficiency : the compressor had to work harder to maintain the required temperature.
-
Risk of overheating of certain internal components.
-
Indoor air more laden with particles , causing discomfort and irritation for sensitive occupants.
-
Excessive condensation on the evaporator fins, which can lead to traces of moisture or mold.
The AirGreen cleaning process: meticulousness and adherence to standards
Our HVAC specialists undertook a complete cleaning according to our internal protocol, adapted to Fujitsu equipment:
1. Preparation and protection
First and foremost, we covered the walls and surrounding paintings to prevent any splashing. The unit was electrically isolated to ensure a safe intervention.
2. Dismantling and inspection
We removed the air filters , front panel, and steering fins to access the evaporator and fan. A quick inspection confirmed the presence of accumulated dust on the coils and greasy residue on the fan blades .
3. Deep washing
The filters were washed in lukewarm water and dried naturally .
The evaporator and fan were then cleaned using a biodegradable and non-corrosive product , designed specifically for aluminum coils.
Using a low-pressure sprayer, we eliminated dust deposits, traces of mold, and microorganisms that could impair air quality.
4. Cleaning the condensation drain
A test of the condensation drain revealed a slight blockage. We cleared it with a controlled jet of water and a cleaning hose, ensuring smooth drainage of the condensate and preventing any risk of overflow.
5. Disinfection and reassembly
An antibacterial solution was applied to the entire air duct and the fan housing.
Once the cleaning was complete, we reassembled the unit, carried out a full test and checked the blowing temperatures.
Results: restored efficiency and cleaner air
The result was immediately noticeable:
-
Airflow increased by almost 30% after cleaning.
-
The fan noise level has decreased.
-
Indoor air quality has improved significantly: no more odor, no more visible particles on nearby surfaces.
-
The device has regained its original performance , easily maintaining the desired temperature with reduced energy consumption.
The client was pleasantly surprised by the difference and decided to add an annual AirGreen preventative maintenance to her residential schedule.
