In-depth maintenance to breathe new life into an outdoor unit
At AirGreen , we were recently called to a residential building in Verdun where a Goodman central heat pump was showing signs of reduced efficiency. The outdoor unit, exposed to dust, urban debris, and humidity, required a complete cleaning to restore its performance and extend its lifespan.
Before our intervention: accumulation of dirt and reduced efficiency
At the time of our inspection, several signs indicated that the heat pump needed maintenance:
-
Dust accumulation on the condenser fins.
-
A clogged fan is slowing down air circulation.
-
Residue stuck to metal surfaces, causing a loss of heat exchange.
-
The unit emitted a slight rubbing noise , typical of a blade unbalanced by dirt.
These symptoms, although common in urban areas, can quickly lead to compressor overload and increased energy consumption .
AirGreen's intervention: safe and efficient cleaning
Our technicians carried out a meticulous cleaning, following the manufacturer Goodman's recommendations :
-
Power outage and site securing.
-
Application of a biodegradable cleaner to dissolve accumulated grease and dust.
-
Controlled water jet cleaning of the fan and condenser — as seen in the photo, this step removes deposits without damaging the fins .
-
Inspect the drain to ensure that no obstruction is hindering the drainage of condensation water.
-
Complete drying and verification of electrical connections before restarting.
This multi-step approach ensures a safe wash, without risk to electronic components, while restoring the performance of the device.
After cleaning: performance and comfort restored
Once the cleaning was complete, the results were immediate:
-
Improved airflow and reduced noise.
-
More stable temperature inside the dwelling.
-
Reduced energy consumption during heating and cooling cycles.
-
Extending the service life of the compressor and mechanical parts.
The customer noted the following day improved efficiency and a reduction in the operating time required to reach the desired temperature.
The importance of regular maintenance
In Montreal and on both the South and North Shores, outdoor units are exposed to urban dust, pollen, leaves, and de-icing salt . Without regular cleaning, a heat pump can lose up to 30% of its efficiency in a single season.
At AirGreen , we recommend a complete cleaning twice a year : in the spring before the air conditioning season and in the fall before the heating season.
Our trained technicians ensure:
-
The use of specialized equipment adapted to each brand (Goodman, Fujitsu, Gree, Tosot, etc.).
-
Strict adherence to the manufacturer's instructions .
-
Using environmentally friendly products to protect your system and the environment.
Professional maintenance is a smart investment: it ensures purified air, optimal comfort and peace of mind .
