Repair of a Goodman central heat pump in Sainte-Thérèse

When the heat sets in, our expertise makes the difference

At AirGreen , we know how essential an efficient HVAC system is to the comfort of North Shore homes. Recently, our team traveled to Sainte-Thérèse for a service call regarding a Goodman central heat pump that was no longer adequately cooling a single-family home. This type of intervention is typical of the first warm days of spring, when systems are restarted after several months of inactivity.

Initial diagnosis: a compressor running, but without effective cooling

Upon arrival, we conducted a thorough inspection of the outdoor unit . The condenser, installed on a stable, slightly elevated metal stand, showed signs of minor wear at the connections. The unit appeared to be working—the fan was running—but no noticeable temperature drop was felt inside.

Our technicians quickly suspected a pressure problem in the refrigeration circuit . By connecting our pressure gauges (visible in the photo: yellow, blue and red hoses), we noticed an abnormally low refrigerant level , indicating a slow leak of R-410A gas .

Repair steps: rigor and precision

To ensure a reliable diagnosis and lasting repair, we have followed these steps:

  1. Complete electrical check : inspection of the external circuit breaker and power wiring. No power faults were found.

  2. Nitrogen leak test : We pressurized the system to identify the exact source of the leak. It came from a slightly cracked fitting at the condenser inlet .

  3. Welding and joint reinforcement : Our certified technician performed a precision weld, followed by a pressure test to ensure the strength of the repair.

  4. Complete vacuuming of the circuit , in order to eliminate all traces of humidity and residual air.

  5. Recharge with R-410A refrigerant , in accordance with Goodman specifications.

  6. Final performance test : verification of pressures, temperatures and air flows.

Results: restored comfort and optimized efficiency

Upon restart, the pressures stabilized and the interior cooling returned to optimal. The customer was able to notice an immediate difference , with cooler air and much quieter operation.

We also advised the owner to have a full annual maintenance , including:

  • Cleaning the outdoor condenser,

  • Checking the indoor coil,

  • Compressor amperage control,

  • Measurement of subcooling and superheat,

  • Inspection of the filter and ducts.

These simple actions can prevent future leaks , improve energy efficiency and extend the life of the system.

The special features of a Goodman central heat pump

Goodman central heat pumps are renowned for their reliability and performance in the Quebec climate. This model, with a power output of approximately 36,000 BTUs , operates efficiently in heating and cooling and uses a high-efficiency scroll compressor. However, like any device exposed to the elements, the seals and connections can become fragile over time—especially after several freeze-thaw cycles typical of the North Shore.

Our certified technicians have the expertise to work on all brands, including Goodman, Trane, Lennox, Midea, Gree, Sharp and Fujitsu , and ensure that every job meets the highest standards of safety and energy performance.
