In the prestigious neighborhood of Westmount, where comfort and design go hand in hand, every detail matters when it comes to maintaining a pleasant indoor temperature year-round. This week, our team at AirGreen was called in for an HVAC service call concerning a Panasonic wall-mounted heat pump installed in a living room that also serves as a home gym.
A versatile space: living room, exercise room, and relaxation area
Upon arrival, our technician quickly realized that this wasn’t your typical room. In addition to a large-screen TV, an elliptical exercise machine, and multiple framed artworks, the space featured a Panasonic wall-mounted heat pump installed high up and centered on the main wall. The client’s goal was clear: resolve the drop in heating and cooling performance, without compromising the room’s décor.
The issue: declining efficiency and unusual noise
The client had noticed two concerning symptoms:
-
Unstable room temperature, despite correct settings on the remote.
-
Unusual operating noise, noticeable even during workouts with background music.
These signs pointed to potential internal buildup, worn components, or a malfunctioning blower motor.
On-site diagnosis: full inspection and performance testing
At AirGreen, we always begin with a thorough and careful diagnostic process. During this service call, our technician followed these steps:
-
Safely disconnected electrical power to the wall unit.
-
Performed a visual inspection of the coils, filters, and fan.
-
Measured airflow temperatures and read the system’s internal error codes.
-
Tested the compressor remotely using the outdoor unit (not visible in the photo but confirmed to be operational).
Problems identified: dust buildup + partial fan obstruction
Our tests revealed the following:
-
A thick layer of dust on the filters and thermal exchanger, limiting the unit’s ability to transfer heat.
-
An unbalanced internal rotor, caused by a build-up of lint and microfibers, likely from workout clothing.
Together, these issues fully explained the rubbing noise, reduced energy efficiency, and inconsistent temperature regulation.
AirGreen’s solution: deep cleaning and recalibration
We proceeded with a meticulous multi-step intervention, taking care to protect nearby wall art:
-
Complete removal of the front cover and filter extraction.
-
Dry cleaning of delicate components.
-
Application of a non-corrosive enzymatic cleaner on the thermal exchanger.
-
Gentle brushing and rotor balancing, followed by a spin test.
-
Drainage system check to avoid condensation risks.
Once everything was reassembled, we restarted the Panasonic heat pump and observed:
-
Smooth and silent airflow with stable fan operation.
-
Target room temperature reached in 6 minutes, about 40% faster than prior to the service.
Restored comfort in a high-use living space
The client, thrilled with the result, immediately noticed an improvement in both air quality and noise levels. This repair resulted in reduced energy consumption and extended the lifespan of the system. We also recommended twice-yearly preventive maintenance, given the room’s frequent use as a fitness area.
