When a Gree air conditioner's performance drops: rapid intervention by AirGreen
At AirGreen , we know that a properly functioning wall-mounted air conditioner is not a luxury, but a necessity during hot summer days in the greater Montreal area. This is exactly what our customer from Sainte-Dorothée, Laval , thought when she contacted us about a performance issue with her Gree wall-mounted air conditioner . The unit seemed to be working, but the air coming out of the louvers was no longer cold enough, even in intensive mode.
Precise diagnosis and AirGreen method
Upon arrival, we conducted a complete inspection of the HVAC system . We found that the air conditioner responded well to the controls, but that the cold airflow was insufficient . Using a professional infrared thermometer , our technicians measured the air outlet temperature at approximately 15°C , well above the expected performance standards (usually between 6°C and 9°C).
This measurement confirmed a lack of cooling efficiency . We then followed our usual protocol:
-
Check filters and coils : slightly clogged with accumulated dust.
-
Inspection of the outdoor coil (condenser) : some fins dirty, reducing heat transfer.
-
Refrigeration circuit pressure test : slight drop in pressure detected.
-
Leak detection : detection of a micro-leak on the service connection.
Complete repair and system recharge
After isolating the leak, our team proceeded to:
-
Tightening and sealing the affected connection with a new gasket.
-
A complete vacuum draw of the circuit to eliminate all traces of humidity or air.
-
A recharge with R-32 refrigerant , in accordance with the Gree manufacturer's specifications.
Once the system was restarted, the blowing temperature dropped to 7°C , optimal efficiency.
We also cleaned the filters and condenser to ensure maximum airflow and extend the life of the unit.
A prevention-focused approach
Our technicians took advantage of this visit to explain to the customer the importance of regular seasonal maintenance . This type of problem could have been avoided with a simple preventive inspection before the warm season. We therefore recommended an AirGreen annual maintenance plan , including:
-
Cleaning filters and coils.
-
Check electrical connections and refrigerant pressures.
-
Condensation water flow control.
-
Adjustment of the air direction flap for better distribution of cold.
