Specialized AirGreen Intervention in a Difficult-to-Access Space
At AirGreen, our reputation is based not only on the quality of our installations but also on our ability to respond effectively in complex situations. Recently, we were called for a service call in Sainte-Julie concerning a Fujitsu wall-mounted heat pump installed under a closed balcony, with very limited space to work. This situation presented a logistical and technical challenge that our team was able to handle with precision and expertise.
Initial Assessment of the Situation on Site
When our team arrived at the residence in Sainte-Julie, they immediately noticed several key elements:
-
A Fujitsu wall-mounted outdoor unit installed high up, fixed to a concrete block wall, under a balcony with minimal clearance.
-
Exposed wiring and partially disorganized cables, including electrical wires and refrigerant lines that appeared to be affected by time.
-
Wall-mounted circuit breaker box located in a hard-to-reach corner, suggesting a connection that needed checking.
-
Decorative hanging light bulbs near the unit, which, although aesthetic, presented a potential risk of interference with the unit's ventilation.
Our technician performed a complete evaluation of the Fujitsu heat pump's operation. Although the unit started up, it was producing abnormal noise outside, and the indoor temperature was not lowering adequately. Everything pointed to a refrigeration or ventilation issue affecting the overall system efficiency.
In-Depth Technical Diagnostics
Our certified technicians then carried out the following steps:
-
Checking the R-410A refrigerant pressure – The results were slightly below the recommended standards, which suggested a slow leak.
-
Inspecting the electrical connections – One of the power cables was slightly corroded at the entry to the wall box, possibly due to moisture infiltration.
-
Examining the outdoor fan – The protective grille contained small obstructions (dust, leaves) that were hindering hot air expulsion.
-
Reviewing the metal support bracket – While still solid, we found that the upper bolts showed signs of surface rust.
Solutions Applied by Our AirGreen Team
To restore this Fujitsu wall-mounted heat pump to full functionality, we implemented a series of targeted and safe actions:
-
Thorough cleaning of the outdoor ventilation grille using a low-pressure jet and biodegradable cleaner.
-
Resealing and rust treatment of the support brackets to ensure the installation's longevity.
-
Partial replacement of the power wiring with new connectors, certified for outdoor use.
-
Leak testing using an electronic detector, followed by a controlled addition of R-410A refrigerant to restore the system’s ideal pressure.
-
Slight repositioning of the hanging decorative cables, as requested by the customer, to prevent them from interfering with air circulation or coming into contact with the fan.
Final Outcome: Fully Functional Heat Pump and Satisfied Customer
At the end of the intervention, the Fujitsu heat pump was working perfectly. The outdoor unit was running quietly, and the indoor module was effectively distributing cool air. The customer immediately noticed a significant improvement in comfort throughout the home.
We also recommended annual preventive maintenance, especially due to the partially enclosed environment under the balcony, to ensure the system operates efficiently in the long run.
