A complete service to revitalize a Sharp heat pump in Sainte-Julie
At AirGreen , we know that a well-maintained wall-mounted heat pump can make all the difference, especially during the temperature fluctuations typical of Montreal's South Shore . Recently, our team traveled to Sainte-Julie to perform a complete cleaning of a Sharp Eco Inverter outdoor unit equipped with Ion Plasmacluster technology. This meticulous service restored the unit's performance and efficiency, while also improving indoor air quality.
Initial diagnosis: clear signs of neglect
Upon arrival, we quickly noticed several signs of fouling:
-
Accumulation of dust and dirt on the protective case.
-
Black marks visible on the cover of the electrical connection box.
-
Condenser fins partially obstructed , limiting airflow.
-
Noise louder than normal, caused by a fan that is unbalanced due to dirt.
The homeowner explained that the heat pump was still working, but that it had lost heating power this fall and seemed to be using less energy . These symptoms are typical of a unit whose heat exchange is hindered by dust and pollutant buildup.
Step 1: Safe cut and thorough inspection
Before any operation, our technician cut off the power supply directly at the heat pump circuit breaker, in accordance with HVAC safety standards .
We then proceeded to:
-
Opening the electrical box to check the condition of the cables and connectors.
-
Inspecting the condenser to determine the dirt density between the fins.
-
Visually inspect the condensation drain to ensure it was not obstructed.
Once these checks were carried out, we were able to confirm that the unit required a thorough but non-invasive cleaning , without complete disassembly.
Step 2: Cleaning the condenser and fins
Using a biodegradable cleaning product specially formulated for aluminum surfaces, we applied a low-pressure foaming solution to the entire condenser.
This foam works deep down to dissolve greasy and organic deposits without damaging the fins.
After a 10-minute exposure time , a rinse with fresh water under controlled pressure removed all impurities.
The result is immediately visible: the fins regain their metallic shine, a sign of optimal heat transfer.
Step 3: Cleaning the case and the cover
The cover of the electrical connection box , slightly blackened by dust and external particles, was cleaned manually with a mild degreaser .
We also wiped and disinfected the exterior surfaces with an anti-static microfiber cloth , ensuring a clean and uniform finish.
This type of cleaning is not just aesthetic: a clean case prevents overheating , facilitates heat dissipation , and protects electronic components against moisture and corrosion.
Step 4: Fan and drain check
The fan was then inspected to ensure it rotated freely and without imbalance. A light dust deposit was removed using a soft brush and a jet of compressed air .
The condensation drain , although still functional, was flushed to prevent any future accumulation.
Results: restored performance and increased efficiency
After cleaning, we carried out a complete functional test :
-
Refrigerant pressure checked and within Sharp manufacturer standards.
-
Defrost cycle successfully tested .
-
More stable blowing temperature and noticeable reduction in noise .
The customer immediately noticed the difference: a more powerful airflow , quieter operation and reduced power consumption .
This simple preventative maintenance operation helps avoid costly breakdowns and extends the lifespan of the heat pump .
