Cleaning a Sharp Eco Inverter heat pump in Boucherville

A complete service to restore performance and longevity

At AirGreen , we provide professional HVAC system cleaning services throughout the South Shore, including Boucherville , where we recently performed a complete service on a Sharp Eco Inverter outdoor heat pump . This unit, installed several years ago, was showing signs of reduced efficiency and a slightly unusual noise at startup.

Initial inspection

Upon our arrival, we conducted a visual and mechanical inspection of the unit.
Our observations:

• Accumulation of dust and wet residue on the front grille and condenser fins;

• Slight imbalance of the fan , causing an intermittent humming noise;

• Traces of grease deposits and air pollution , typical of a residential environment exposed to fine particles.

Although the Sharp unit is known for its durability, the lack of regular maintenance was beginning to reduce airflow and heat dissipation capacity.

Cleaning steps

1. Power outage and securing the area : Before any intervention, we disconnected the heat pump and secured the work perimeter to prevent any water splashes.

2. Removal of the front grille and fan : Allowing complete access to the condenser coils and the lower tank.

3. Application of an eco-friendly cleaner : We used a biodegradable product designed to dissolve grease and dust without attacking metals or coatings.

4. Cleaned with fresh water under controlled pressure : A low-pressure rinse made it possible to free all the fins without deforming them, ensuring optimal air circulation.

5. Cleaning the casing and support : As the unit is mounted on an aluminum frame with a treated wood base, we also disinfected and dried the area to prevent corrosion and mold growth.

6. Drain and motor check : The drain was clear and no oil leaks were detected. The motor was lubricated and tested after reassembly.

Results and performance after cleaning

At the end of the cleaning:

• The noise level has returned to normal , a sign that the fan was running at full stability;

• The hot/cold air flow rate has increased significantly , confirming improved condenser efficiency;

• The customer noted an improvement in system responsiveness and reduced energy consumption during subsequent cycles.

The unit was restarted under observation for several minutes: smooth operation, stable discharge temperature, and proper condensate drainage. A final pressure and temperature test confirmed that the system was operating to its original specifications.

The importance of preventative cleaning

Even a recently installed heat pump needs to be cleaned at least once a year to maintain its energy efficiency and prevent premature wear of its components.
Sharp Eco Inverter devices, equipped with Plasmacluster technology, require careful maintenance to preserve air quality and the purity of the ionized flow they produce.

At AirGreen, we conduct these interviews with:

• non-toxic products ;

• specialized tools adapted to each brand;

• and a methodology that complies with the manufacturer's recommendations .

Each cleaning aims not only to restore performance, but also to extend the life of your heat pump while maintaining your comfort season after season.
