A fast and efficient service call from AirGreen
At AirGreen , we were recently called to intervene in Sainte-Dorothée, Laval , for a problem with a Panasonic Inverter wall-mounted heat pump . The customer contacted us after noticing that their system was no longer providing the expected air conditioning and that the outdoor unit was producing an abnormal noise. With summer approaching, speed of intervention was essential.
On-site diagnosis: identify the cause of reduced performance
Upon our arrival, our certified technician performed a complete inspection of the system.
Here are the main findings:
-
Abnormally low R-410A refrigerant pressure , indicating a possible microleak.
-
Condenser coil slightly dirty , reducing heat exchange.
-
Unusual vibration at the fan , caused by an imbalance due to an accumulation of dust.
Using our digital diagnostic instrumentation, we were able to confirm that the leak was coming from the flare fitting at the compressor outlet , a common problem on some Panasonic models after several years of use.
Repair steps: rigor and precision
Once the diagnosis was confirmed, our team took the following steps:
-
Safe recovery of remaining refrigerant gas using an approved recovery unit.
-
Replace the flare fitting and tighten to the torque recommended by Panasonic .
-
Deep cleaning of the outdoor condenser using a biodegradable product to improve efficiency.
-
Rebalancing the fan and tightening the internal fixings.
-
Complete vacuuming of the refrigeration circuit , then precise recharging of the refrigerant according to the nameplate (1.05 kg).
-
Complete system testing in heating and cooling modes to validate pressure stability, airflow and energy efficiency.
Results: comfort restored and efficiency restored
At the end of our intervention, the Panasonic wall-mounted heat pump regained its full cooling and heating capacity . The customer immediately noticed:
-
A reduction in external noise ,
-
Better diffusion of fresh air ,
-
And stabilized electricity consumption .
This type of repair demonstrates the importance of regular preventative maintenance , especially before extreme seasons. An undetected leak can not only reduce efficiency, but also damage the compressor in the long run.
