An urgent service call after a complete system failure
At AirGreen , we know that a central heat pump failure in the middle of the transition season can quickly affect the comfort of an entire home. This is exactly what happened to a customer in LaSalle , southwest of Montreal , whose Goodman central heat pump stopped overnight without warning.
The context: a suddenly silent system
Our client, the owner of a typical brick duplex in the neighborhood, noticed that his central HVAC system would no longer start, despite attempts to restart the thermostat. There was no ventilation, no compressor noise, and no visible error signals.
The customer's initial checks—changing the thermostat batteries and resetting the circuit breaker—had yielded nothing, so he called our AirGreen service team for a complete inspection .
Diagnosis: Compressor start capacitor failure
Upon arriving on site, our technicians Émilie and Vincent quickly undertook a complete diagnosis of the system:
-
Voltage check : 240 V present at the outdoor unit.
-
Contactor inspection : in good condition.
-
Capacitor measurement : no microfarad reading — a completely faulty start capacitor .
This component, essential for starting the compressor and fan, naturally wears out over time, especially after several heating and cooling cycles. In this specific case, the capacitor had a bulge on the top , a typical sign of failure due to heat and age.
The intervention: rapid replacement and complete verification of the system
Our technicians replaced the dual capacitor (45/5 µF, 440 V) with an original Goodman part.
Here are the steps of the intervention:
-
Safely disconnect the power supply before handling.
-
Removing the old capacitor and cleaning the electrical compartment.
-
Installation of the new capacitor , with anti-vibration mounting.
-
Power up and complete boot test .
-
Compressor current control and refrigeration cycle verification .
As soon as it was restarted, the heat pump resumed normal operation, with a smooth start-up and a constant air flow inside the home.
Results: comfort restored and reliability assured
After 20 minutes of testing, the blowing temperature in the ducts dropped from 21°C to 12°C , confirming optimal refrigeration.
The customer immediately noticed the return of thermal comfort and the reduction in compressor noise — a consequence of a stable and balanced restart.
We took advantage of the visit to:
-
Clean the condenser fins to improve air circulation.
-
Check the refrigerant charge to ensure maximum efficiency.
-
Advise the customer on seasonal maintenance (spring condenser washing, air filter replacement, annual inspection).

AirGreen tips to prevent this type of breakdown
To avoid capacitor or starter failures, we recommend our customers to:
-
Schedule an annual inspection before the summer period.
-
Visually check the outdoor unit for corrosion, dirt, or vibration.
-
Maintain a free space of at least 60 cm around the condenser.
-
Watch for warning signs : humming on startup, repeated restarts, warm air coming out of the ducts.
These simple steps extend the life of a central heat pump and ensure optimal performance year after year.
