A typical service call in a residential environment in Laval
At AirGreen , we regularly work in the quiet residential neighborhoods of Sainte-Rose in Laval , where many homes are equipped with central heating and cooling systems . Recently, our team was called to diagnose a fault on a Goodman central heat pump , installed outside a typical red brick house in the area.
The outdoor unit, securely mounted near the wall and protected by the rear terrace, was showing signs of irregular operation : the customer noticed a lack of heating performance , accompanied by an unusual vibrating noise when the compressor started up.
Detailed diagnosis and technical inspection
Our technicians began with a complete inspection of the refrigeration circuit and the control system . After verification, several elements caught our attention:
-
Abnormal pressures observed on pressure gauges, suggesting a possible lack of refrigerant.
-
Weakened starting capacitor , explaining the starting noise and irregular cycles.
-
Clogged interior filters in the air distribution system, reducing overall efficiency.
A minor leak of R-410A refrigerant was subsequently located at the junction of a flare fitting, likely due to prolonged slight mechanical vibration.
Repair and refurbishment steps
Our specialists have taken the following steps to restore system performance :
-
Replaced the starting capacitor with a high durability Goodman compatible model.
-
Repair and tighten the flare fitting after cleaning the copper and applying optimal tightening torque.
-
Leak test under nitrogen , followed by a complete vacuum .
-
Recharge with R-410A refrigerant according to Goodman's recommended pressure ratings.
-
Cleaning the outdoor coil with fresh water and checking the airflow at the fan.
Once the repair was completed, the system returned to stable operation , with balanced pressure and optimal thermal efficiency.
Results: restored comfort and optimized performance
The customer immediately noticed the difference:
-
Regular warm air in all rooms.
-
Condenser noise reduction .
-
Improved energy consumption based on readings from the connected smart thermostat.
This intervention perfectly illustrates our philosophy: precise diagnosis, lasting repair and complete customer satisfaction .
