An urgent service call on the West Shore
On a hot day in Sainte-Anne-de-Bellevue , one of our customers contacted us after noticing that their Gree wall-mounted air conditioner was no longer cooling efficiently. The outdoor fan was running, but there was no cooling inside. This type of situation is common during the summer, especially when the unit hasn't received maintenance for several seasons.
At AirGreen , we know how essential a well-performing HVAC system is for everyday comfort. We quickly dispatched one of our certified technicians to the location to diagnose and repair the unit.
Detailed diagnosis of Gree air conditioner
Upon arrival, our technician conducted a thorough inspection of the outdoor wall-mounted compressor , installed approximately two meters above the ground. The unit, securely mounted on a wooden cladding wall, showed some signs of wear:
-
Lids slightly loose;
-
Evaporator coils covered with a thin film of dust and pollen;
-
Fan blades in good condition but rotating at an abnormal speed.
An electrical and refrigeration pressure test identified the root cause: a problem with the electronic control module . This crucial component, responsible for regulating the compressor and fan speed, had experienced a power surge, likely related to a power fluctuation.
Steps of repair
After securing the unit and turning off the power, the technician took the following steps:
-
Disassembly of the front panel and top cover to access the control module.
-
Visual inspection of the printed circuit board : burn marks and burnt components confirming the failure.
-
Replacement of the original Gree control module with a new generation compatible part, more resistant to voltage variations.
-
Complete cleaning of the condenser and ventilation turbine , to ensure optimal air circulation.
-
Recommissioning and full performance test : the compressor returned to normal operation, and the cold air flow returned to its original intensity.
Result: comfort and efficiency restored
Once the repair was completed, the unit was tested for approximately 30 minutes at various speeds. The system quickly reached the programmed temperature of 21°C.
The customer immediately noticed the difference: silence, power and comfort returned.
We also took advantage of the intervention to recommend:
-
Annual preventive maintenance , including cleaning the coils and checking the condensate drain.
-
Adding a surge protector to prevent this type of outage from recurring.
