A complete balcony cleaning to restore the heat pump's performance and efficiency.
At AirGreen , we know that in urban areas like Outremont , the outdoor units of wall-mounted heat pumps are often exposed to dust, debris, and harsh weather. These conditions gradually reduce their energy efficiency and can even cause the compressor to overheat.
During this intervention, our team carried out a complete cleaning of a wall-mounted heat pump installed on a balcony , a confined space requiring precision and method.
Initial diagnosis: dust accumulation and decreased efficiency
The client contacted us after noticing:
-
A lower than usual indoor airflow ;
-
An inconsistent temperature in the apartment;
-
And an increase in electricity consumption .
On site, a visual inspection of the outdoor unit revealed:
-
A thick layer of dust and particles on the top cover;
-
Obstructed condenser fins ;
-
And a clogging of the drain caused by the accumulation of urban waste (fine dust, pollen, small debris).
These signs indicated a lack of ventilation and heat dissipation , two factors that directly impair system performance.
AirGreen Cleaning Steps
1. Securing and preparing the balcony
Working in a confined space requires careful logistics.
We first protected the surrounding surfaces and installed a recovery tarp to prevent any water from flowing towards the neighbors below.
The unit was then electrically disconnected to ensure a safe intervention.
2. Dusting and opening the unit
The top cover was removed to access the condenser grille.
Using a compressed air blow gun , we removed the dust that had accumulated in the fins and around the fan.
This delicate work made it possible to clear the air passages without bending the slats.
3. Eco-friendly washing and rinsing of the condenser
A biodegradable cleaning solution , specially designed for HVAC systems, was applied to the fins and coil.
After a period of time to dissolve the ingrained dirt, a low-pressure water jet was used to rinse everything, ensuring a thorough cleaning while preserving the sensitive components.
4. Check the drain and refrigeration connections
The condensation drain , often neglected, was unblocked to prevent water backflow.
We also inspected the insulation of the refrigeration pipes and the tightness of the fittings , as aging of the sheaths and heat can cause slight cracks.
5. Final test and performance validation
After complete drying, the heat pump was restarted.
The performance test showed:
-
A 25% improvement in airflow ;
-
A reduction in operating noise ;
-
And a return to a stable and consistent temperature inside.
The customer immediately noticed improved comfort and a reduction in cooling time .
Results: comfort, efficiency and longevity
This preventative cleaning not only restored the heat pump to its original efficiency, but also preserved its lifespan .
Outdoor units located on balconies or terraces often accumulate dust and urban debris more quickly, hence the importance of annual maintenance .
Regular maintenance allows for:
-
To reduce energy consumption ;
-
To improve indoor air quality ;
-
And to avoid costly breakdowns related to compressor overheating.
