Effective intervention for a heat pump with reduced efficiency
At AirGreen , we work daily in homes on the South Shore of Montreal , where many Goodman systems ensure the comfort of families. That day, we were called to Sainte-Julie to diagnose a Goodman central heat pump that was no longer producing enough cooling. The client, concerned about the indoor temperature rising despite the system being in operation, contacted us for a complete inspection.
A methodical and precise diagnosis
Our technician first performed a visual check of the outdoor condenser. Located on the side of a brick house, the Goodman unit appeared to be in good physical condition: no oil leaks , no abnormal noises , but the discharge pressure was surprisingly low.
We then have:
-
Test the pressure of the refrigeration circuits with our digital pressure gauges.
-
Inspected the compressor and fan for performance.
-
Examined the electrical wiring and starter relays.
The verdict was quickly reached: a minor leak of R-410A refrigerant at the service valve connection. This gradual loss of fluid explained the system's declining performance and the lengthening of cooling cycles.
Heat Pump Repair Steps
-
Power supply cut-off to ensure safe intervention.
-
Leak detection using an electronic detector and application of soap bubbles to confirm the exact location.
-
Soldering the defective connection using silver solder.
-
Complete vacuuming of the circuit to eliminate all traces of humidity.
-
Accurate recharge with R-410A refrigerant according to Goodman specifications.
-
Complete performance test , including verification of suction and discharge pressures, as well as measurement of delta T (incoming/outgoing air temperature difference).
Once recharged, the heat pump returned to its nominal values. The customer immediately noticed cooler air and a rapidly stabilizing indoor temperature.
Prevention and personalized advice
Our technician took advantage of this intervention to provide some preventive recommendations :
-
Clean outdoor coils regularly , especially in summer, to ensure optimal heat dissipation.
-
Check the clear area around the condenser , as shrub branches can interfere with air circulation.
-
Schedule a complete annual maintenance , ideally before hot weather, to ensure the system maintains its energy efficiency.
Additionally, we proposed the installation of a refrigeration line moisture barrier and protective voltage monitoring to prevent future electrical problems related to frequent voltage fluctuations on the network.
Result: restored performance and comfort regained
After the work, the Goodman heat pump returned to optimal operation:
-
Balanced pressures ,
-
Fast and constant cooling ,
-
Normal energy consumption ,
-
Reduced operating noise .
The customer, satisfied with the professionalism and clarity of our explanations, enrolled his system in our AirGreen maintenance program , guaranteeing two visits per year and priority interventions in the event of a breakdown.
