Essential maintenance for a heat pump exposed to the elements
At AirGreen , we frequently encounter systems installed on the flat roofs of residential buildings in Montreal. On this particular day, our team traveled to the Côte-des-Neiges neighbourhood to perform a complete cleaning of a Manuflow heat pump installed on the roof of a building surrounded by trees. This unit, while still performing well, was visibly affected by the accumulation of dust, moss, and natural debris, typical of systems exposed to the elements and surrounding foliage.
Diagnosis before cleaning: an appliance slowed down by dirt
From our initial inspection, we noted several signs indicating an urgent need for maintenance:
-
An accumulation of dust and foam on the base and around the fins.
-
Dirty heat exchange fins , reducing energy efficiency.
-
Ventilation slowed by dirt that had infiltrated the turbine.
-
Risks of overheating due to poor air circulation.
These symptoms compromised both the energy efficiency of the device and the indoor air quality.
The AirGreen professional cleaning process
Our team followed a rigorous cleaning method that complied with the manufacturer's standards , Manuflow :
Step 1: Preparation and securing
We first disconnected the power supply and protected the connections to prevent any water from entering the electronic components. The device was then lifted and stabilized to facilitate cleaning of the lower surfaces and the stand.
Step 2: Deep Cleaning
Using a biodegradable cleaning product , we carefully cleaned:
-
The condenser fins , using a low-pressure water jet to avoid deforming them.
-
The fan was disassembled and washed to remove accumulated dust.
-
The hood and protective grille , often forgotten but essential for good air circulation.
We also checked the system's drainage to prevent any risk of stagnant water and long-term mold growth.
Step 3: Final checks
After complete drying, the unit was tested. We measured:
-
An improvement in airflow of more than 30% .
-
A reduction in operating noise , a sign of a clean and balanced fan.
-
Improved energy efficiency , resulting in faster start-up and more even cooling.
The benefits of regular maintenance
A rooftop heat pump cleaning like this one offers several major advantages:
-
Prevention of costly breakdowns caused by overheating or obstruction of airflow.
-
Reduction in energy consumption .
-
Improved indoor air quality , thanks to optimal heat exchange.
-
Extended lifespan of compressor and fans .
At AirGreen, we always emphasize the importance of annual maintenance , especially for units installed outdoors and exposed to vegetation.
