Repair of a Wall-Mounted Nordik Heat Pump at Pointe-aux-Trembles: A High-Level Challenge Mastered by AirGreen

When a customer from Pointe-aux-Trembles contacted us about a performance issue with their Nordik wall-mounted heat pump, we knew from our first visit that this would not be a standard intervention. Installed more than five meters high, above a cathedral ceiling staircase, the unit required not only in-depth technical expertise but also meticulous planning to ensure a safe, effective, and uncompromising intervention.

A problem with airflow and thermal performance

The client told us that their Nordik heat pump was no longer properly heating the space, despite recent basic maintenance. The air blown was lukewarm, even cold, even in heating mode. They suspected a failure of the compressor or the indoor fan.

However, our team of certified technicians quickly identified that the problem was not mechanical but related to a buildup of dust and debris on the indoor heat exchanger, as well as poor condensation drainage, likely caused by a partial drain blockage.

A complex location to manage

Working at this height without full scaffolding was a logistical challenge. We therefore used a system of reinforced industrial ladders, anchored to the lower floor, while respecting the strictest safety standards. Once at height, our technicians carefully removed the wall unit cover to access the internal components.

Precise repair steps

Here are the details of the technical operations carried out by our AirGreen team:

• Thorough inspection of the indoor unit to confirm the absence of refrigerant leaks.

• Complete cleaning of the evaporator with a non-corrosive degreasing product specially designed for high installations.

• Vacuuming and rinsing of the drainage trap, which was clogged with organic residues (dust, accumulated moisture).

• Checking the ambient temperature sensor, which was poorly calibrated and not reading correct data.

• Resetting the electronic circuit to restore factory settings and improve communication between the thermostat and the unit.

Thanks to this comprehensive intervention, the thermal performance of the heat pump was immediately restored, with a constant flow of warm air and better temperature regulation in the double-height space.

Client interaction: education and peace of mind

The client was particularly relieved to find that the Nordik equipment did not need to be replaced, as they had initially feared. We took the time to explain the specific risks related to units installed at height: accelerated dirt buildup, drainage defects invisible to the naked eye, and difficulty with regular maintenance.

We also recommended professional HVAC maintenance every 12 months, especially for this type of atypical installation in a vertically open space.

Particularities of the Nordik brand

The Nordik brand is known for its compact wall units, but sometimes less accessible in terms of after-sales service. This requires in-depth mastery of internal circuits, especially for diagnosing electronic sensors and thermal regulation parameters.

Our technicians are specifically trained on this type of system, which allows us to solve complex breakdowns without relying exclusively on manufacturer recommendations.

Advice for wall-mounted heat pump owners

Here are some best practices we recommend to owners of wall-mounted heat pumps like this one:

• Avoid installations too high, unless architecturally unavoidable.

• Regularly clean the filters (ideally every month during heavy use).

• Schedule a complete annual inspection to prevent progressive performance loss.

• Be attentive to unusual noises or weak airflow, early signs of a problem.

Final result and client satisfaction

Following our intervention, the Nordik heat pump is operating optimally. The client immediately noticed a significant improvement in thermal comfort, especially on the upper floor of their home. They also decided to join our AirGreen annual maintenance program to prevent any future issues.

This type of service call perfectly illustrates our commitment to providing reliable, safe HVAC service perfectly adapted to every situation, even the most complex.
