A swift intervention for a heat pump malfunction in a bright condo
At AirGreen, every service call is an opportunity to showcase our expertise and commitment to customer satisfaction. This time, we were contacted for a repair of a wall-mounted Midea heat pump in a residential condo located in Montréal-Est, where the customer was experiencing intermittent performance issues and a lack of cooling, despite having a recently installed unit.
Initial diagnosis: no airflow and a partially closed flap
When our technician arrived on site, they immediately noticed a very weak airflow coming from the wall unit. A quick visual inspection revealed that the top flap of the heat pump wasn’t opening fully—a common issue related to a faulty swing motor or an internal mechanical blockage.
We also observed that the air filters were clogged with dust buildup, which contributed to reduced airflow and created excessive internal pressure on the heat exchanger.
Steps taken to repair the Midea heat pump
-
Powering down the unit to ensure a safe intervention.
-
Fully opening the unit’s front panel to access internal components.
-
Thorough cleaning of the air filters, intake grilles, and ducts using a HEPA vacuum and a dry microfiber cloth.
-
Inspection of the swing motor: after testing, the motor was found to be functional, but a piece of plastic from packaging that hadn’t been removed properly was partially blocking the mechanism.
-
Removing the blockage and lightly lubricating the flap mechanism to restore smooth operation.
-
Restarting the unit and calibrating the automatic flap using the remote control.
Immediate results after the repair
As soon as the unit was restarted, the top flap opened completely, and airflow was instantly restored to an optimal level. The client noticed a difference within seconds: air was circulating efficiently again, and the room temperature was already beginning to stabilize.
Our technician took the time to explain to the client the best maintenance practices, including cleaning the filters regularly every two months and monitoring the behavior of the oscillating flap.
A complex environment: wall placement and side airflow circulation
The Midea unit was installed right next to a side wall grille, possibly connected to a central ventilation system or a return air duct. This particular setup had the potential to interfere with the air distribution of the heat pump, creating turbulence that could worsen the issue.
We recommended leaving at least 30 cm of clearance around the wall unit to avoid recirculating expelled air and suggested installing a discreet foam deflector if airflow issues reoccurred.
