Goodman wall-mounted air conditioner repair in Sainte-Dorothée

A quick service call to restore comfort

At AirGreen , we were recently called to Sainte-Dorothée (Laval) for a problem with a Goodman wall-mounted air conditioner . The customer contacted us after noticing that his unit was no longer blowing cold air despite a normal display on the remote control.

Our technician quickly arrived on site to perform a complete diagnosis of the HVAC system . The wall-mounted unit, installed in a main living room, appeared clean on the surface, but a slight clicking noise was heard upon startup—a classic sign of a stuck motorized shutter or a faulty indoor fan motor .

Detailed diagnosis and technical inspection

As soon as the front panel was opened, the technician carried out a series of precise checks:

  • Correct supply voltage (240V confirmed).

  • Communication between indoor and outdoor unit intact.

  • No error code visible on the electronic card .

  • Indoor fan not responding to command despite voltage being applied.

These results pointed our team towards a faulty blower motor . After some further testing, it was confirmed that the indoor fan motor was burned out due to a buildup of dust that caused gradual overheating.

Repair carried out on site

Once the cause was identified, our technician began replacing the fan motor with a genuine Goodman part, ensuring long-term compatibility and reliability. A thorough cleaning of the evaporator coil and internal housing was also performed before final reassembly.

Once the new part is installed:

  • The cold air blowing immediately resumed;

  • The room temperature dropped from 27°C to 22°C in less than 15 minutes;

  • The sound level has returned to normal, ensuring quiet operation.
