A Successful Service Call in Kirkland: Repair of a Polarbear Wall-Mounted Heat Pump

A fast intervention to get a malfunctioning wall-mounted AC system back up and running

At AirGreen, our mission is to provide professional, fast, and reliable HVAC service throughout Greater Montreal, including Kirkland, on the West Island of Montréal. We were recently contacted for an urgent service call regarding a Polarbear wall-mounted heat pump that was no longer functioning properly in a single-family home.

The client reported a lack of cool air, an unusual noise when the unit started up, and that the system was no longer responding to the remote control. During this transitional season, it was crucial for the homeowner to quickly regain optimal indoor comfort.

Initial diagnosis: pinpointing the invisible faults

As soon as we arrived on-site, we conducted a full visual and functional inspection of the Polarbear wall-mounted unit. Although the device appeared clean from the outside, it presented several internal signs of wear:

• Air filters clogged with dust and fine particles;

• Weak start capacitor, preventing the unit from properly starting the compressor;

• Partially defective main control board, causing the issues with the remote control;

• Built-up dirt on the indoor coils, reducing thermal exchange.

These combined problems explained both the loss of performance, erratic start-up behavior, and intermittent breakdowns reported by the client.

Repair process: precision, expertise, and efficiency

Our team carried out a series of targeted repairs to restore the full capacity of this Polarbear wall-mounted heat pump:

1. Complete cleaning of the air filters and coils using biodegradable, non-corrosive products to restore optimal airflow.

2. Replacement of the start capacitor, a critical component for smooth compressor start-up.

3. Reset and reprogramming of the control board, pending the installation of a new part ordered from Polarbear.

4. Calibration of the temperature sensor, which had lost accuracy over time.

We also checked the refrigerant R410A levels, confirming the unit had no leaks, which is essential to maintain consistent energy efficiency.

Results: a performing heat pump and a satisfied customer

Once the repairs were completed, we performed a series of performance tests. The unit restarted without issue, with perfect responsiveness to the controls, optimal airflow, and normal sound levels. The client immediately noticed a significant improvement in thermal comfort, with the indoor temperature being quickly regulated.

We took the time to advise the client on how to maintain their wall-mounted heat pump, including:

• Cleaning the filters every 2 to 3 months;

• Scheduling an annual preventive maintenance with our certified technicians;

• Monitoring for any unusual noise or performance drop.
