A service call for a high wall built-in appliance
At AirGreen , we were recently called about a problem with a built-in air conditioner in a condo in Ville Mont-Royal . The client, concerned about a lack of cooling and an abnormal noise when his unit was turned on, contacted us to diagnose and repair his Gree indoor system installed above a laundry area.
Context of the intervention
The sleek, high-ceilinged home featured a Gree wall-mounted unit with a recessed floor-to-ceiling interior system , carefully integrated into a wall niche. This type of installation, often favored in modern condos, provides discreet comfort without encroaching on living space.
Our RBQ certified technician first checked the air circulation , noting restricted airflow . The unit was clogged with a buildup of dust and textile fibers, likely vacuumed from the closet adjacent to the laundry room.
Technical diagnosis
After a complete inspection:
-
Clogged filters : drastically reducing airflow.
-
Clogged evaporator coil : impacting heat exchange.
-
Partially blocked drainage : causing slight accumulation of water under the sump.
-
Slightly displaced thermal probes , distorting the ambient temperature reading.
These symptoms explained the irregular cycles and lack of performance observed.
Repair process
Our experts carried out:
-
A thorough cleaning of the coil using a non-corrosive product designed for Gree units.
-
Replacing filters with washable fine mesh models, optimizing filtration.
-
Cleaning the drain with a vacuum pump and checking that it is flowing properly to the outside.
-
Repositioning of the probes and calibration of the temperature sensor.
-
A check of the refrigeration pressures , confirming that the circuit had no leaks.
Once these steps were completed, the system was put back into service and immediately resumed stable and quiet operation.
Results and recommendations
The device has regained its original performance:
-
Stable and uniform temperature , even in the upper areas of the condo.
-
Noise reduction to less than 38 dB, in line with Gree standards.
-
Significant improvement in indoor air quality thanks to optimized filtration.
Our technicians recommended:
-
Annual maintenance before the hot season to prevent dust accumulation.
-
The installation of a protective mesh in the niche to prevent the re-inhalation of particles from the upper cupboard.
