Rapid intervention for a dirty and inefficient device
At AirGreen , we know how quickly improper maintenance can affect the performance of a wall-mounted air conditioner . Recently, our team responded to a service call in Sainte-Anne-de-Bellevue , in the west end of Montreal, regarding a Sharp wall-mounted air conditioner that was no longer effectively cooling the main living space of a single-family home.
The context of the intervention
The customer had noticed that his air conditioner, although installed only three years ago, had lost its efficiency:
-
The air came out warm despite the temperature being set at 21°C.
-
The airflow seemed reduced.
-
The operating light was flashing continuously, indicating possible fouling or a clogged sensor.
Our certified technician came the same day for a complete diagnosis .
Diagnosis: saturated filters and clogged heat exchanger
As soon as I opened the top cover of the indoor unit, an obvious problem appeared:
The air filters were completely clogged with dust and microfibers, preventing proper air circulation. The heat exchanger, too, had a layer of accumulated dirt, drastically reducing the system's energy efficiency.
We also noticed a slight accumulation of water in the condensate tray, a direct consequence of poor drainage due to the obstruction.
Steps of repair and cleaning
-
Disassembly and complete inspection : removal of filters, upper casing and air distribution fins.
-
Thoroughly clean the filters in warm water with a mild detergent, then dry completely before replacing.
-
Cleaning the evaporator coil using a specialized non-corrosive product, which dissolves deposits without damaging the aluminum coating.
-
Checking the condensate drain , unblocking and completely rinsing the drain pipe.
-
Antibacterial disinfection to eliminate all traces of mold or bacteria that could affect indoor air quality.
Result: performance and comfort restored
After reassembling and rebooting the system, the results were immediate:
-
Blowing temperature measured at 12.4°C , confirming optimal cooling.
-
Airflow restored to 100% of its nominal capacity.
-
Reduced noise level, thanks to cleaning of the blades and internal turbine.
The customer was impressed by the difference in both comfort and air quality .
AirGreen tips to prevent this type of problem
At AirGreen, we recommend to our clients:
-
Clean the filters every two months during the summer season.
-
Have an annual professional maintenance carried out including checking the drain, refrigerant pressure and overall performance.
-
Avoid operating the system with clogged filters, as this can damage the compressor in the long run.
