When a client in Pointe-aux-Trembles contacted us about performance issues with their Nordik wall-mounted heat pump, we knew from the first visit that this wouldn’t be a standard service call. Installed more than five meters high, above a stairwell with cathedral ceilings, the unit required not only advanced technical expertise but also meticulous planning to ensure a safe, efficient, and uncompromising intervention.
Airflow and Thermal Performance Issues
The client explained that their Nordik heat pump was no longer effectively heating the space, despite a recent basic maintenance attempt. The air coming out was lukewarm or even cold, even when set to heating mode. They suspected a compressor failure or an issue with the indoor fan.
However, our team of certified technicians quickly determined that the issue wasn’t mechanical, but due to a buildup of dust and debris on the indoor heat exchanger, along with poor condensate drainage, likely caused by a partially clogged drain line.
A Complex Location to Access
Servicing equipment at this height without full scaffolding posed a logistical challenge. We used industrial-grade reinforced ladders, anchored securely to the lower floor, while strictly following the highest safety standards. Once in position, our technicians carefully removed the unit's front panel to access the internal components.
Detailed Steps of the Repair
Here’s a breakdown of the technical operations carried out by the AirGreen team:
-
Thorough inspection of the indoor unit to confirm there was no refrigerant leak.
-
Full cleaning of the evaporator coil using a non-corrosive degreasing product designed specifically for high-up systems.
-
Vacuuming and flushing the condensate tray, which was clogged with organic debris (dust, built-up moisture).
-
Calibration of the ambient temperature sensor, which was misreading and providing inaccurate data.
-
Resetting the control board to restore factory settings and improve communication between the thermostat and the unit.
Thanks to this comprehensive intervention, the heat pump’s thermal output was immediately restored, with a consistent flow of warm air and improved temperature regulation throughout the open vertical space.
Client Interaction: Clarity and Peace of Mind
The client was visibly relieved to learn that the Nordik unit did not need replacement, as they had initially feared. We took the time to explain the unique challenges of units installed at height: accelerated buildup of dirt, hidden drainage issues, and difficulty of regular upkeep.
We also recommended scheduling a professional HVAC maintenance check every 12 months, especially for this kind of installation in a vertically open space.

The Unique Features of the Nordik Brand
The Nordik brand is known for its compact wall-mounted units, which can be less accessible in terms of after-sales service. This calls for in-depth understanding of the internal circuitry, especially when diagnosing sensor issues or system misreadings.
Our technicians are specifically trained on these systems, which allows us to solve complex problems without solely relying on manufacturer diagnostics.
Tips for Wall-Mounted Heat Pump Owners
Here are some best practices we recommend for owners of wall-mounted heat pumps like this one:
-
Avoid installations that are too high up, unless absolutely necessary for architectural reasons.
-
Clean the filters regularly (ideally once a month during peak usage).
-
Schedule an annual full inspection to avoid gradual efficiency loss.
-
Watch for unusual noises or weak airflow, which are early signs of an issue.
