Repair of a Frigidaire central heat pump in Boisbriand

A service call for a loss of power in the middle of early summer

At AirGreen , our work on central heat pumps intensifies with the first warm days of spring in Quebec. This was the case in Boisbriand , on the North Shore, where a customer contacted us after noticing that his Frigidaire central heat pump was no longer able to effectively cool his home, despite the continuous operation of the outdoor fan.

The customer also mentioned an abnormal increase in his electricity consumption and prolonged operating cycles , two characteristic signs of a system suffering from an imbalance between pressure, airflow and refrigeration.

Complete on-site diagnosis

Once on site, our AirGreen-certified technician began with a methodical inspection of the Frigidaire outdoor unit—a vertical condensing central heat pump installed on a metal base to ensure proper ventilation and prevent moisture buildup.

The initial analysis revealed several anomalies:

  • Condenser clogged by dust and plant debris accumulated over the seasons;

  • Refrigerant pressure too low , indicating a minor leak in the suction line ;

  • Compressor start capacitor slightly at the end of its life, causing irregular start;

  • Slightly dirty coils , reducing heat exchange capacity.

This type of breakdown is common in spring, especially after long months of winter inactivity.

Technical repair steps

Our team always follows a comprehensive refresher protocol , designed to ensure durability and optimal performance:

  1. Deep cleaning of the condenser using a low-pressure jet and a biodegradable product specific to HVAC coils.

  2. Complete electrical check : test of the start capacitor and compressor relays.

  3. Replacement of the defective capacitor with a certified genuine Frigidaire part.

  4. Leak detection using an electronic detector with infrared sensor.

  5. Repaired the suction fitting and tested with nitrogen to ensure it is leak-proof.

  6. Recharge with R-410A refrigerant according to the manufacturer's exact specifications.

  7. Final functional test with inlet/outlet temperature reading and suction and discharge pressure control.

After these interventions, the system regained its nominal efficiency: a temperature delta of 10°C between the suction and blown air, proof of optimal performance.

Regained comfort and restored efficiency

Once the repair was complete, the Frigidaire heat pump was once again providing even, quiet cooling throughout the house. The customer immediately noticed the rapid heating and the return of a virtually imperceptible noise level .

We also made some minor adjustments to the thermostatic control to optimize duty cycles and avoid excess power consumption—a service we routinely include in our HVAC repair services.

Maintenance tips to extend the life of a central heat pump

Our technicians took advantage of the intervention to remind the customer of some essential actions:

  • Clean the condenser at least once a year (ideally in spring);

  • Change the indoor filter every 2 to 3 months during the air conditioning season;

  • Maintain a clear area of ​​at least 60 cm around the outdoor unit;

  • Schedule annual preventative maintenance with an AirGreen certified professional.

These simple practices can prevent up to 80% of common breakdowns and ensure stable energy performance throughout the season.
