A meticulous repair by AirGreen in a residential home in Montreal West
At AirGreen, every service call is an opportunity to showcase our precision, technical expertise, and commitment to the comfort of residents in Montreal West and the surrounding areas. Today, we’re sharing a real example of a repair on a Panasonic wall-mounted heat pump, installed close to a sloped ceiling in a residential bedroom.
Service context: inconsistent performance reported
Our client, the owner of a single-family home in the quiet sector of Montreal West, contacted us due to erratic performance from her Panasonic wall-mounted heat pump. According to her observations, the unit was blowing lukewarm air instead of cooling efficiently, despite proper settings. She also noted intermittent noises when the directional flaps were opening.
Technical inspection: accurate and targeted diagnosis
Upon arrival, our certified technicians immediately began a full inspection of the indoor unit. This Panasonic wall-mounted heat pump, installed at an angle near the ceiling and above a door frame, appeared to be in good visual condition. However, after opening the front panel, several critical issues were noted:
-
Dust and mold buildup on the evaporator fins.
-
Obstructed flap motor, causing creaking and blockage in directional control.
-
Miscalibrated internal temperature sensor, leading to inaccurate ambient readings.
-
Clogged air filters, reducing airflow efficiency.
These combined issues explained the unit’s reduced performance as well as the unusual sounds.
Repair steps: cleaning, calibration, and part replacement
Our intervention unfolded in several methodical steps:
-
Complete cleaning of the evaporator coils using an approved antibacterial product to remove dirt, mold, and greasy buildup responsible for energy inefficiency.
-
Partial disassembly of the flap mechanism, followed by lubrication and realignment of the rotating motor to ensure smooth, quiet operation.
-
Replacement of the air filters with a compatible, new, washable Panasonic model.
-
Calibration of the internal temperature sensor on the control board, allowing for more precise and responsive ambient temperature readings.
-
System restart, testing of cooling and heating cycles, airflow verification, and temperature measurement at the air outlet.
Results: restored performance and a reassured client
After the repairs, the wall-mounted heat pump was operating at full capacity, with air temperatures at the outlet matching factory specifications. The noise level also returned to normal, with no more creaks or stuttering. Our client expressed immediate relief, appreciating the professionalism, speed, and transparency of our intervention.

This wall-mounted model, while sleek and discreet, is often prone to sensor and motorized flap issues after a few years without maintenance.
