A quick service call to restore home comfort on the South Shore
At AirGreen , we were recently called to Boucherville to work on a Gree wall-mounted air conditioner that was no longer producing cold air, despite an indicator light indicating normal operation. The customer, concerned about a possible major breakdown, wanted a quick and lasting repair before the next heat wave.
Diagnosis: A dirty indoor unit and a clogged drain
Upon arrival, our technician noticed that the wall-mounted unit showed clear signs of internal fouling: dust-covered fins, a wet evaporator coil , and irregular condensate flow. After removing the cover, a detailed inspection revealed a partially blocked drain pipe , causing water to accumulate and an automatic safety shutdown of the compressor.
Our technicians then:
-
Checked the R-32 refrigerant pressure , confirming correct charge.
-
Checked the temperature probes and the electronic card , all in good condition.
-
Cleaned the condensate drain and applied an antibacterial solution to prevent future clogging.
Technical intervention: complete cleaning and return to service
Following the diagnosis, we carried out a complete cleaning of the indoor unit using a pressure-controlled device, specially designed for Gree systems. This process removes micro-deposits without damaging the delicate surface of the evaporator.
We also replaced the refrigerant pipe insulation tape , visible in the photo, to improve thermal performance and prevent external condensation on the duct. Once the maintenance was carried out, the air conditioner was restarted: the cold air resumed immediately, and the system returned to optimal efficiency.
Restored performance and a reassured customer
Thanks to our intervention, the energy performance of the Gree air conditioner was fully restored. The customer immediately noticed an improvement in airflow and a reduction in operating noise. We also recommended annual preventive maintenance , which is essential to extend the life of his unit and avoid this type of breakdown during periods of heavy use.
