A dirty heat pump affecting performance and comfort
At AirGreen , we were recently called to Saint-Eustache , on the North Shore , to perform a complete cleaning of a York brand central heat pump . The client contacted us after noticing a significant drop in the performance of their system: lukewarm air in heating mode, increased energy consumption, and unusual noise coming from the outdoor unit.
Upon arrival, our team observed a significant accumulation of dust, plant debris, and winter salt on the condenser fins. This type of buildup is common when the unit is left outdoors without annual cleaning, especially in residential areas prone to dust and extreme temperature fluctuations, such as those in Saint-Eustache.
Diagnosis and preparation before cleaning
Before proceeding with the cleaning, we inspected:
-
The general condition of the upper fan and motor ;
-
Electrical connections and protections ;
-
The insulated refrigerant pipes showed signs of superficial wear;
-
The internal filters and coils were heavily clogged.
This inspection confirmed that the problem stemmed from a lack of preventative maintenance. Excessive fouling of the coils restricts heat exchange, forcing the compressor to run longer and reducing its lifespan.
Deep cleaning of the York heat pump
We then proceeded with a methodical and complete cleaning of the system:
-
Safe disconnection of the power supply and implementation of necessary protections.
-
Removing the top cover to access all the condenser fins.
-
Vacuuming and gentle brushing to remove surface deposits.
-
Application of a biodegradable cleaner specially formulated for heat exchangers.
-
Rinse at low pressure to remove all traces of dirt without damaging the fins.
-
Cleaning of condensate lines to prevent backflow or unpleasant odors.
-
Checking for leaks and tightening electrical connections .
Each step was carried out in compliance with the recommendations of the manufacturer York and the safety standards applicable to the HVAC sector.
Results after intervention
After cleaning, the difference was immediate:
-
The airflow has been restored to full capacity;
-
The blown temperature has returned to its constant level;
-
The operating noise level has decreased significantly;
-
And most importantly, electricity consumption has been reduced.
The customer noticed within the first few hours a return to optimal thermal comfort in his home, while also benefiting from a quieter and more efficient system.
The importance of annual maintenance
This case perfectly illustrates the importance of regular preventative maintenance for any central heat pump. A simple annual cleaning performed by a certified professional like AirGreen allows you to:
-
To increase the lifespan of the compressor;
-
To reduce energy costs;
-
To improve indoor air quality;
-
And to prevent costly breakdowns before they occur.
