Kenmore central system repair in Sainte-Dorothée

When the reliability of a Kenmore system meets the expertise of AirGreen

At AirGreen , every service call is a new opportunity to bring an HVAC system back to life and ensure the comfort of families in the greater Montreal area. Recently, our team traveled to Sainte-Dorothée (Laval) to diagnose and repair a Kenmore central system , a model known for its robustness but which, over time, requires careful maintenance.

An accurate diagnosis from the first visit

The customer contacted us after noticing that his Kenmore central air conditioner was no longer cooling his home effectively, even when the thermostat was set to a low temperature. When listening to the outdoor fan, he heard an unusual noise—a classic sign of a faulty fan motor or capacitor .

Upon our arrival, our certified technicians carried out a complete inspection:

  • Checking the starting capacitor (measuring the capacitance in microfarads)

  • Condenser Fan and Bearing Inspection

  • Cleaning the condenser coil (clogged with dust and external debris)

  • Monitoring R-410A refrigerant pressures using electronic pressure gauges

  • Compressor operating current analysis

These steps revealed two main anomalies:

  1. The starting capacitor was reading 35% below its rated capacity.

  2. The outdoor fan motor showed signs of intermittent overheating.

Fast repair and original replacement parts

To restore optimal system performance, our technicians replaced:

  • The capacitor is doubled by a model of the same capacity (45/5 µF).

  • The fan motor is a Kenmore compatible replacement part, with improved energy efficiency.

All of this was done in compliance with CSA electrical protocols and ensuring perfect sealing of the connections . After replacement, the refrigerant pressures were recalibrated, and a full test cycle confirmed that the compressor was now operating at full efficiency .

Cleaning and preventive maintenance: the key to increased longevity

Before leaving the site, our team took care to:

  • Clean the condenser coil using a biodegradable cleaner.

  • Check the blowing temperature inside the main duct (result: 8°C difference between the return air and the blown air — perfect performance).

  • Suggest to the customer annual preventive maintenance including cleaning the indoor coil and checking the condensate.

Result: restored comfort and optimized performance

After our intervention, the client immediately noticed the difference:
The cold air was circulating evenly throughout the house again, and the Kenmore system was running quietly and efficiently , just like the first day.

Thanks to targeted replacement and complete calibration, we have:

  • Reduces system power consumption by 18%.

  • Stabilized the compressor operating current at its nominal values.

  • Extended the useful life of the system by at least 5 years.

Why choose AirGreen for your Kenmore repairs in Laval

Maintenance Tips for a Kenmore Central Air Conditioner

To prevent this type of breakdown, we recommend:

  1. Clean the outdoor condenser at least twice a year.

  2. Replace the interior air filter every 2 to 3 months during the summer season.

  3. Avoid obstructing the flow of outside air (leaves, grass clippings, bags).

  4. Have the refrigerant pressure checked every 2 years.

  5. Schedule a complete preventative maintenance every spring.

These simple actions can prevent costly repairs and extend the life of the system by several years.
