In the peaceful neighbourhood of Notre-Dame-de-Grâce, in Montréal, our team recently responded to an HVAC service call concerning a Nordik wall-mounted heat pump installed in a carefully decorated home. This intervention took place in a room where thermal comfort is essential: the living room, adorned with a charming display wall of vintage cups and tableware. The context was clear: despite regular maintenance, the unit was no longer operating efficiently in heating mode, which posed a problem for the family who spent most of their winter evenings there.
An intimate setting, an unexpected technical challenge
As soon as we arrived, we were greeted by a homeowner concerned about the performance of her wall-mounted heating system. She explained that the Nordik wall-mounted heat pump had started making a faint clicking noise and that the heating was no longer consistent. This created uncomfortable temperature fluctuations in the main living area. Visually, the unit looked clean and well-integrated into the decor, but internal signs of wear were suspected.
Technical diagnosis: a thorough inspection of the Nordik heat pump
At AirGreen, we know that a precise diagnosis is essential before any intervention. Here are the steps we followed:
-
Inspection of the indoor unit: No clogged filters, no excessive dust accumulation — a good sign.
-
Analysis of indicator lights and error codes: An intermittent code appeared on the panel, indicating a malfunction of the temperature sensor.
-
Listening to the compressor at startup: An irregular noise suggested a difficult compressor start, possibly linked to an issue with the electronic board.
-
Measurement of refrigerant pressure: The circuit pressures indicated a slight loss of gas efficiency, requiring a partial recharge.
Actions taken: a complete system refresh
Once the issues were identified, we carried out a targeted and thorough repair:
-
Replaced the wall temperature sensor: A key component for the proper operation of heating mode.
-
Deep cleaning of the internal coils: Despite the clean appearance, a thin greasy film was preventing optimal thermal exchange.
-
Inspection and tightening of connectors on the electronic board: Several connections appeared weakened, which could disrupt signal transmission to the compressor.
-
Partial recharge of R410A refrigerant: To ensure stable and energy-efficient performance throughout the winter.
-
Full functionality test: 30 minutes of active monitoring to confirm that the Nordik wall-mounted heat pump was running smoothly again, without unusual noise.
Result: comfort restored, homeowner reassured
At the end of our intervention, the client immediately noticed a significant improvement in warm airflow, along with restored quiet operation. She told us how relieved she was to get through the winter without needing to replace the unit. For her, the living room is a place of relaxation and connection, and consistent thermal comfort was non-negotiable.
We also recommended an annual preventive maintenance check at the beginning of each fall to extend the lifespan of her Nordik wall-mounted heat pump.
