Goodman wall-mounted air conditioner repair in Sainte-Julie

A service call for restored comfort

At AirGreen , we were recently called to Sainte-Julie, on Montreal's South Shore, to work on a Goodman wall-mounted air conditioner installed above a patio door. The customer contacted us after noticing that the unit was no longer producing cold air and that a slight vibrating noise was being heard each time the compressor started.

Diagnosis: A clogged system and a tired fan

Upon arrival, we conducted a thorough inspection of the Goodman wall-mounted air conditioner. This model, installed over 10 years ago, showed typical signs of wear:

  • filters clogged with dust,

  • dirty evaporator fins,

  • indoor fan motor producing irregular noise,

  • slight refrigerant leak detected at copper pipe connection.

These combined problems resulted in decreased energy efficiency and loss of cooling power .

Step 1: Deep cleaning the indoor unit

We started by disassembling the front panel and the fan housing to perform a complete cleaning :

  • degreasing the turbine,

  • steam washing of the evaporator coil,

  • disinfection of the condensate tray and drain to eliminate any mold buildup,

  • replacement of the air filter with an original Goodman compatible model.

This cleaning helped restore optimal airflow and eliminate odors that had settled in the room.

Step 2: Repair and recharge the refrigeration circuit

We then checked the refrigerant pressure and confirmed a slow leak at the flare connection on the indoor unit side.
After tightening, we carried out:

  • a nitrogen leak test,

  • a complete vacuum draw of the system,

  • then a recharge of R410A refrigerant according to the manufacturer's specifications Goodman.

Once the load stabilized, the compressor resumed quiet and smooth operation.

Step 3: Replacing the Interior Fan Motor

The fan motor showed signs of mechanical fatigue (worn bearing, vibration at startup). We installed a new genuine Goodman motor , recalibrated to ensure smooth and quiet rotation.
This replacement has significantly improved the sound comfort of the system.

Step 4: Electrical Check and Final Calibration

Finally, we checked:

  • supply voltages,

  • the state of the starting capacitor ,

  • how the wall thermostat works.

After these adjustments, the air conditioner reached full performance: 18°C ​​in less than 20 minutes in the main room, proof of a return to optimal efficiency.

Result: restored comfort and improved energy efficiency

Thanks to this complete intervention , the Sainte-Julie client has regained a comfortable indoor climate and reduced energy consumption .
