A heat pump in difficulty: our intervention in Sainte-Thérèse
At AirGreen , we were recently called for an HVAC repair service in Sainte-Thérèse , on the North Shore of Montreal . The customer contacted us after noticing that his Comfortmaker central heat pump , installed outside his single-family home, was no longer able to properly heat his residence despite the fan apparently working.
Accurate diagnosis of a central system
Upon our arrival, our technicians first conducted a complete inspection of the outdoor condenser . We quickly discovered that the unit was operating with R-410A refrigerant , a fluid frequently used in modern systems, but sensitive to any micro-leaks.
Initial indications pointed to an abnormal pressure drop in the refrigeration circuit. Using our measuring instruments, we confirmed a slight pressure drop. In addition, an electrical check revealed a weakened compressor starter (capacitor) , a common fault that can cause irregular cycles and difficult compressor startup.
Repair Steps
Our technicians undertook a series of methodical interventions:
-
Safe draining and recovery of R-410A refrigerant using our certified recovery station.
-
Replacement of the defective capacitor with a Comfortmaker compatible part.
-
Nitrogen inspection and micro-leak detection on service fittings. A small leak was identified and sealed with solder.
-
Complete vacuum to eliminate all traces of humidity.
-
Accurately recharge with R-410A refrigerant according to manufacturer's specifications.
-
Final check of pressures, intensities and air flows to ensure optimal performance.
Result: restored comfort and optimal performance
As soon as the system was restarted, the heat pump returned to its nominal efficiency . The discharge temperature was stable and the pressures perfectly balanced. The customer could feel the difference from the first minutes: restored comfort and quiet, stable operation .
We also recommended annual preventative maintenance to the owner including:
-
Complete cleaning of the outer coil;
-
Checking the refrigerant charge;
-
Drain and wiring inspection;
-
Measurement of operating pressures.
The importance of professional repair
A central heat pump, especially with R-410A refrigerant , requires careful handling and certified equipment . A poorly repaired leak or incorrect refrigerant dosage can lead to excess energy consumption and reduced compressor life. At AirGreen, we not only ensure rapid repair , but also prevent future breakdowns through practices that comply with HVAC industry standards.
