A complete service to restore shine and performance to an outdoor unit
At AirGreen , we pride ourselves on offering comprehensive, thorough, and safe HVAC cleaning services. Our team recently traveled to Boucherville , on Montreal's South Shore , for a deep cleaning of a Daikin wall-mounted heat pump whose outdoor unit was showing signs of fouling after several seasons of use.
Initial observation before our intervention
The customer contacted us after noticing a significant decrease in the cold airflow and an unusual noise during operation of their unit. Upon inspecting the outdoor unit, our technician observed:
-
A layer of dust and pollen covering the condenser fins.
-
Traces of moisture and accumulated dirt on the bodywork and grilles.
-
An irregular flow of condensation water, a sign of a partially blocked drain .
-
Greasy residues due to ambient pollution and projections from surrounding vegetation.
These elements, although common, can reduce the energy efficiency of a heat pump by 20 to 30% if not addressed in time.
The steps of a professional AirGreen cleaning
Our team carried out a complete and methodical cleaning , respecting Daikin's recommendations and best practices in the HVAC industry.
1. Securing and technical diagnosis
Before any work was carried out, we disconnected the heat pump's power supply and checked the condition of the wiring, insulation, and refrigerant connections. This step ensures safe working practices and allows us to identify any signs of premature wear.
2. Manual dusting and brushing
Using a soft-bristled brush , we gently removed the accumulated deposits from the grilles and the top cover. This first step prevents dirt from penetrating deeper during washing with water.
3. Application of a biodegradable cleaning product
We then sprayed an environmentally friendly cleaner , specially designed to dissolve grease and contaminants without damaging metal surfaces or harming the environment. This product works deep into the condenser fins and fan.
4. Rinse with fresh water and clean the fins
Using a low-pressure water jet , we carefully rinsed each surface to remove all traces of dirt and detergent. The airflow through the condenser immediately returned to normal.
5. Checking and clearing the drain
The condensation drain was cleaned using a light pump to prevent any accumulation of stagnant water, a common cause of corrosion and unpleasant odors.
6. Disinfection and finishing
We completed the cleaning with an antibacterial disinfection to prevent mold growth and ensure healthy indoor air quality. Finally, a final rinse and drying of the casing restored the heat pump to its original appearance.
Results observed after cleaning
After the system has been restarted:
-
The operating noise has decreased significantly.
-
Energy efficiency has been optimized.
-
The indoor air has become fresh, clean and odorless again .
-
The outdoor unit had an impeccable appearance , proof of the care taken at every stage.
