An intervention in the city center for a broken air conditioner
At AirGreen , we were recently called to a condo in downtown Montreal , in the Ville-Marie area, for an urgent repair of a Midea wall-mounted air conditioner . The customer contacted us after noticing a significant water leak along the interior wall, just below the wall unit.
Quick diagnosis: condensate leak and weakened installation
Upon arrival, we found that the front panel of the Midea air conditioner had been removed, revealing drip marks on the wall . The unit, installed a few years ago, had two distinct problems:
-
Water accumulation in the drainage tray , caused by a partially blocked condensate pipe.
-
Weakened wall mounting , the unit was no longer perfectly straight, which disrupted the flow of water to the outside.
The symptoms were typical:
-
Intermittent gurgling noises.
-
Water flowing down the interior wall.
-
Reduced air conditioning efficiency.
Steps of repair
Our AirGreen certified technician undertook a methodical, multi-step repair:
-
Partial disassembly of the Midea wall unit using a professional suction cup bracket to stabilize the unit during the intervention.
-
Complete cleaning of the drainage pipe with a jet of compressed air and a disinfectant treatment against organic deposits.
-
Straightening of the wall plate and reinforced fixing with “toggle bolt” type anchors, ensuring perfect alignment for the proper flow of condensation.
-
Checked the temperature sensor and indoor fan : no anomalies detected.
-
Replace the cover and fully test the system in cooling mode to ensure proper operation of the cycle and drainage.
Results: Leak eliminated and performance restored
As soon as the intervention was completed, we observed a regular flow of condensate to the outside and a blown temperature of 9°C, a sign of a perfectly functional system. The customer immediately noted:
-
Better cooling efficiency .
-
The complete absence of water noise inside.
-
A wall now dry and intact , without additional infiltration.
Maintenance tips to prevent future leaks
Our technicians took the opportunity to share practical recommendations:
-
Clean the filters every month during the summer season.
-
Schedule preventative maintenance in the spring to check the condensate pan and drainage.
-
Avoid placing objects under the wall unit , in order to detect any leaks in time.
We have also added this installation to the AirGreen maintenance register , guaranteeing annual monitoring to prevent any risk of blockage of the drainage system.
