Essential maintenance for optimal performance
At AirGreen , we know that proper HVAC maintenance is the key to lasting comfort and maximum energy efficiency. Recently, our team travelled to Sainte-Anne-de-Bellevue , on the western tip of the Island of Montreal, to perform a complete cleaning of a wall-mounted heat pump whose performance had significantly decreased.
Symptoms before our intervention
The customer had noticed:
-
A decrease in the perceived airflow in the house.
-
Unusual noises coming from the outdoor unit.
-
Electricity consumption has been rising for the past few weeks.
Upon inspecting the outdoor unit, we immediately identified the cause: the heat exchanger fins were covered with a thin layer of dust and dirt , accumulated over the seasons. This buildup significantly reduced the heat exchange capacity, forcing the compressor to work harder to maintain the indoor temperature.
Steps in professional cleaning
Our certified technician performed a complete service according to best practices , including:
-
Safe power outage and system disconnection.
-
Complete visual inspection of the coils, fan and condensation tray.
-
Application of a biodegradable cleaner to the heat exchanger fins.
-
Gentle jet cleaning with water under controlled pressure, so as not to damage the slats.
-
Checking and clearing the condensation drain , which is often responsible for odors or overflows.
-
Clean the fan and case to remove all traces of dust and moisture.
-
Restart and performance test , including pressure measurement and temperature differential control.
Results after cleaning
Upon recommissioning, the results were immediately visible:
-
The airflow had become strong and stable again .
-
The compressor was running more quietly .
-
The indoor temperature is reached more quickly .
-
And above all, restored energy efficiency , synonymous with long-term savings.
The importance of preventative maintenance
This case perfectly illustrates why annual heat pump cleaning is essential. Without maintenance, dust, pollen, and fine particles accumulate on the heat exchange surfaces, causing:
-
A drop in yield of up to 30%.
-
Premature wear of internal components.
-
An increase in electricity consumption .
-
And in some cases, costly breakdowns that can easily be avoided.
At AirGreen, we recommend a complete cleaning every spring or fall , depending on system usage. Our team covers all of Greater Montreal— Montreal, Laval, Longueuil, the North Shore, and the South Shore —and travels quickly to provide professional, safe, and efficient service.
