Fedders wall-mounted air conditioner repair in Brossard

A typical service call turned into a success

At AirGreen , we regularly receive calls for older wall-mounted air conditioners , often from historic brands like Fedders , known for their robustness but now requiring specialized maintenance. This is exactly the case with this Fedders wall-mounted air conditioner , installed in a small apartment in Brossard , on the South Shore of Montreal .

The unit, over ten years old, was showing signs of weakness: inefficient cooling , excessive noise , and unscheduled shutdowns . The owner was concerned about having to replace it, but our team quickly identified a sustainable repair solution , avoiding a costly replacement.

Diagnosis: a tired but recoverable device

Upon our arrival, we carried out a complete inspection of the Fedders wall-mounted air conditioner . This model, typical of the 2000s, has an integrated ventilation system and a simplified electronic control board , housed on the right side of the front.

Our initial observations:

• Air filters completely clogged , reducing airflow.

• Worn start capacitor , causing hesitant compressor starts.

• Abnormal fan noise , caused by a dirty and slightly unbalanced motor .

• Traces of dust and mold in the evaporator.

This type of failure is common in older wall-mounted air conditioners: dust accumulation prevents heat dissipation, causing the compressor to overheat and compromising overall performance.

Repair Steps

Our technicians have undertaken a complete overhaul :

1. Thorough cleaning

The front panel and filters were removed, pressure washed with a biodegradable cleaner, and then dried. The evaporator was disinfected and degreased using a chlorine-free antibacterial product suitable for residential appliances.

2. Replacing the starting capacitor

We replaced the original 35 µF capacitor with an equivalent CSA certified model, ensuring better compressor start-up and greater electrical stability.

3. Fan lubrication and balancing

The blower motor was disassembled, cleaned and lubricated with high temperature dielectric oil . We also balanced the blades to eliminate vibration.

4. Electrical check and final test

A complete test of the electrical circuit confirmed a stable 120V power supply . After reassembly, the unit was restarted:

• Outlet air temperature: 12°C (excellent performance).

• Power consumption reduced by 15% .

• Noise level lowered by 6 dB .
