During a recent service call in Brossard, our AirGreen team was contacted to diagnose and resolve a technical issue affecting a Panasonic wall-mounted heat pump installed on the façade of a residential building. This intervention highlighted both the technical challenges of an outdoor unit mounted high above ground level and our ability to provide reliable, safe, and professional HVAC repair service in complex conditions.
A concerned client facing unusual noise
The owner of a multi-unit building located in Brossard, on the South Shore of Montreal, reached out to us after noticing a strange mechanical noise coming from the outdoor unit of his Panasonic wall-mounted heat pump. The unit, mounted more than 4 meters above the ground on a brick wall, had recently begun emitting vibrations and squeaking sounds, especially noticeable at night.
This kind of noise can have several possible causes: an unbalanced fan, a failing motor, alignment issues, or debris caught inside the unit. In this case, the job required a thorough technical analysis as well as strict safety measures to access the equipment.
On-site diagnosis: safety and precision
Upon arrival, our technicians assessed the access conditions to the outdoor unit. The equipment was securely installed on wall brackets attached to the brick surface, positioned high enough to require a professional-grade safety ladder and a safety harness meeting fall protection standards.
Once in position, our technicians carried out:
-
A complete mechanical check of the fan and compressor.
-
An inspection of the brackets and structural support.
-
A visual inspection inside the unit, checking for foreign objects or signs of wear.
The verdict: the fan motor showed significant wear, with mechanical imbalance causing the audible vibrations. Additionally, a build-up of dust and debris was disrupting the airflow across the ventilation blades.
Safe repair and targeted replacement
Thanks to our inventory of parts compatible with Panasonic wall-mounted models, we were able to proceed with an on-site repair:
-
Thorough cleaning of the outdoor unit, including fan blades.
-
Replacement of the worn fan motor.
-
Lubrication of internal components and blade realignment.
-
Performance testing of the unit post-repair.
The job was completed in under two hours, with all necessary precautions taken to protect our technicians, maintain the integrity of the installation, and ensure the safety of the building’s occupants.
Immediate results and a reassured client
By the end of our intervention, the Panasonic wall-mounted heat pump was running silently again, with stable output and indoor comfort fully restored. The client was especially impressed by our quick response, our ability to handle elevated installations, and the quality of our on-site diagnostics.
This repair avoided a full unit replacement, representing a significant cost savings for the property owner while ensuring a durable solution.
