An urgent service call on the West Shore of Montreal
At AirGreen , we were recently called to intervene in Pointe-Claire , in one of the residential neighborhoods on Montreal's West Shore , for a problem with a York central heat pump installed on the roof of an apartment building. The client contacted us after noticing that their HVAC system was no longer producing cold despite a running compressor. This type of situation is common at the end of summer, when the heat puts a strain on aging equipment.
Diagnosis: A faulty fan motor
As soon as we arrived on the roof, our certified technician carried out a complete inspection of the outdoor unit. The York model, known for its robustness, was however showing signs of wear: rust on the upper grille , dust accumulated on the condenser , and above all unusual noise at startup . After checking the refrigerant pressures and the compressor inrush current, the diagnosis was made: the upper fan motor was seized .
This type of failure prevents proper heat dissipation, quickly leading to compressor overheating and system shutdown. Without prompt intervention, the damage could have become serious.
Repair: Engine replacement and complete maintenance
Our team immediately took the necessary steps to restore the heat pump:
-
Turn off the power supply and check the circuit safety.
-
Disassembly of the upper fan to access the motor.
-
Complete replacement of the fan motor , with an original York compatible model.
-
Complete cleaning of the condenser using a biodegradable product to improve heat transfer.
-
Inspect electrical wiring and tighten connections to prevent arcing.
-
Check refrigerant level (R-410A) and leak test.
-
Recommissioning and full performance testing.
Once the work was completed, the York heat pump resumed normal operation, displaying stable pressure and a discharge temperature in line with the manufacturer's specifications .
Result: comfort restored and prevention of future breakdowns
The client immediately noticed an improvement in indoor comfort and a reduction in outside noise. We also took the time to explain some good preventative maintenance practices :
-
Clean air filters regularly.
-
Avoid obstructing exterior air inlets.
-
Schedule an annual inspection before extreme seasons (summer and winter).
-
Have motors and capacitors checked every two years.
Thanks to this quick intervention, we were able to avoid premature replacement of the compressor , a repair that would have cost several hundred dollars more.
