Goodman wall-mounted air conditioner repair in Chomedey

Rapid diagnosis and effective intervention: AirGreen expertise in action

At AirGreen , we are regularly called to diagnose and repair Goodman air conditioning systems throughout the greater Montreal area. This intervention took place in Chomedey , a well-known residential area of ​​Laval , where a customer contacted us after noticing that their Goodman wall-mounted air conditioner was no longer producing cold air, despite the exterior fan apparently working.

The context of the service call

The customer, who owns a condo located on the top floor of a brick building, noticed a gradual loss of performance in his Goodman wall-mounted air conditioner over the past few days. Although the outdoor unit appeared to be operating normally, the indoor temperature remained stable, indicating a lack of refrigerant or an internal pressure problem .

Upon our arrival, we carried out a complete diagnosis of the HVAC system , including:

  • Checking the electrical voltage and the Siemens circuit breaker connected to the outdoor unit.

  • Visual inspection of refrigeration connections and coil.

  • Measurement of refrigerant gas pressure and subcooling.

  • Checking the communication between the indoor unit and the compressor.

Diagnosis confirmed: refrigerant leak at a connection

Our technicians quickly identified a refrigerant leak at a slightly corroded refrigeration line connection, likely due to exposure to the elements and repeated vibration. This failure explained the gradual decline in performance and the prolonged, ineffective operation of the compressor .

Steps of repair

  1. Recovery of residual refrigerant using our environmentally compliant recovery station.

  2. Complete cleaning of the connection and resoldering with silver , guaranteeing a perfect seal.

  3. Nitrogen pressure test to ensure there are no leaks.

  4. Vacuum to eliminate any traces of moisture in the circuit.

  5. Complete recharge with R-410A refrigerant according to Goodman specifications.

  6. Restart and calibrate the system with verification of suction and discharge pressures.

Results after repair

As soon as it was restarted, the Goodman air conditioner returned to optimal performance:

  • Powerful and stable cold air from the first minutes.

  • Balanced pressures and evaporation temperature in accordance with manufacturer standards.

  • Normalized sound level , indicating that the compressor was no longer overloaded.

The client immediately felt the difference, happy to find comfort in his Laval condo.
