A careful intervention to restore the optimal performance of a wall system
At AirGreen , we work every day across Greater Montreal to restore high-performance, long-lasting HVAC systems. Recently, our team traveled to Pointe-Claire , in the West Island, to repair a Fujitsu wall-mounted heat pump installed on a red brick wall of a single-family home. This situation is typical of residential neighborhoods on the West Shore, where reliable heating and cooling are essential year-round.
Diagnosis: A noisy and inefficient Fujitsu heat pump
The customer contacted us after noticing abnormal noise and a decrease in performance from their Fujitsu wall-mounted heat pump. The system appeared to be working, but the indoor temperature was no longer stabilizing properly, and power consumption had increased.
Upon our arrival, our certified technicians carried out a complete diagnosis:
-
Checking the outdoor module mounted on a galvanized steel wall bracket.
-
Inspection of refrigeration fittings and pipe insulation .
-
Measuring the pressure of R410A refrigerant .
-
Analysis of the electronic card and the control module .
The verdict: a minor refrigerant leak and premature wear of the external fan , which explained both the noise and the loss of efficiency.
Complete repair and refurbishment of the system
In order to restore the unit to its optimal performance, our team has undertaken a series of specific actions:
-
Refrigerant gas recovery using a certified recovery unit.
-
Repairing a leak in a soldered copper fitting.
-
Replacement of the outdoor fan motor , whose bearings were seized.
-
Nitrogen pressure leak test to ensure seal reliability.
-
Complete recharge in R410A according to the specifications of the manufacturer Fujitsu.
-
Cleaning the coil and compressor housing .
-
Final check of pressure and amperage values , confirming that performance has returned to normal.
Results: restored comfort and maximum efficiency
At the end of the intervention, the Fujitsu wall-mounted heat pump found:
-
Quiet operation , without vibration or friction.
-
A stable temperature in the main area of the house.
-
Energy consumption reduced by approximately 20%.
-
And above all, a reassured customer, happy to see the responsiveness and precision of our service.
