Maintenance is necessary for lasting efficiency in urban environments.
At AirGreen , we recently completed a full cleaning of a Daikin wall-mounted heat pump installed on a balcony in the Plateau-Mont-Royal neighbourhood of Montreal . This type of intervention perfectly illustrates the challenges encountered in urban environments where outdoor units are often exposed to dust, debris, and, as in this case, objects placed directly on the unit .
Before our intervention: a clogged and neglected appliance
When we arrived on site, the client's Daikin heat pump showed several signs of poor maintenance :
-
A cracked flower pot , placed on top of the unit, had allowed damp soil to leak through the holes.
-
A layer of dust and dirt covered the top cover and the condenser fins.
-
Air circulation was partially blocked , compromising heat dissipation.
The customer had noticed a drop in performance and unusual noise during air conditioning operation. These symptoms were consistent with a clogged condenser and reduced airflow.
AirGreen's intervention: a complete and safe cleaning
Our technicians carried out a meticulous cleaning , following professional steps adapted to the Daikin brand and the constraints of a restricted space, typical of balconies in Plateau-Mont-Royal.
Step 1 — Site preparation and securing
-
Complete removal of the flower pot and cleaning of the top of the unit.
-
Protection of the balcony and wall against water splashes.
-
Checking the stability of the base and the condensate drainage.
Step 2 — Dismantling and cleaning the outdoor unit
-
Gentle suction of the fins to remove dust, dirt and debris.
-
Low-pressure cleaning with a controlled water jet , to avoid any deformation of the fins.
-
Application of a biodegradable cleaning product to dissolve accumulated grease and dirt.
-
Inspection of electrical connections and preventive tightening of terminals.
Step 3 — Checking the internal module
Although the problem was primarily located outside, we also checked:
-
The condition of the internal filters , slightly clogged, cleaned with warm water and dried.
-
The condensation drain , rinsed to prevent any obstruction.
Results: a Daikin heat pump that looks like new
After our visit, the customer immediately noted:
-
An improvement in cooling power .
-
Quieter operation .
-
Increased temperature stability inside.
We advised the customer never to place any objects on their outdoor unit , as this prevents ventilation and can reduce the compressor's lifespan.
The importance of regular cleaning in an urban environment
In areas like the Plateau-Mont-Royal , where dust, fine particles, and debris are common, annual heat pump maintenance is essential to:
-
Maintain optimal energy efficiency .
-
Avoid premature breakdowns .
-
Preserve indoor air quality .
-
Ensure compliance with the manufacturer's recommendations .
