A service call to a downtown Montreal condo
At AirGreen , we are often called upon to work in urban condos where space is limited and wall-mounted air conditioning systems play a vital role in daily comfort. This Fujitsu wall-mounted air conditioner , installed in a modern apartment in the Ville-Marie district, had a water flow problem that worried the owner.
After a few days of intensive use in cooling mode, water began to leak down the wall near the electrical panel. The customer then decided to stop using the unit and contacted us for an urgent inspection .
Diagnosis: a blocked condensate drain
Upon our arrival, our technician carried out the basic checks: power supply, filter, and turbine condition. The Fujitsu was working correctly in terms of blowing and temperature, but the condensate basin was full , a clear sign of a blocked drainage pipe .
In high-rise apartments, it is common for the drain line to be long or slightly inclined , which can cause stagnant water to accumulate and algae to form. This obstruction prevents water from draining properly to the outside.
Intervention: complete cleaning and realignment of the drain
Our team carried out a thorough cleaning of the condensate drainage system using a vacuum pump and a biodegradable disinfectant agent.
Then we have:
-
Removed the bottom cover of the wall unit to access the drip tray;
-
Cleaned the air filters and the exchanger fins ;
-
Realigned the drainage pipe to correct the insufficient slope;
-
Checked for proper water circulation using a controlled flow test.
Once the system was reassembled, the unit was restarted: the water flowed freely outside, and the Fujitsu air conditioning returned to its optimal performance without noise or leaks.
Result: comfort and tranquility restored
The owner, reassured, was able to see that the ambient temperature stabilized quickly and that no trace of humidity reappeared on the wall.
We also recommended annual preventive maintenance , especially before the summer season, to avoid this type of problem recurring.
