A complete renovation in the middle of winter
At AirGreen , we recently completed a full cleaning of a York central heat pump in Terrebonne , on Montreal's North Shore. The outdoor unit, installed on the ground near a foundation wall, showed obvious signs of soiling after several seasons of exposure to dust, fallen leaves, and snow. A quick and thorough intervention was necessary to ensure the performance and longevity of the HVAC system .
Context and initial diagnosis
The homeowner contacted us after noticing a decrease in heating power and unusual frost on the outdoor unit. Upon inspection, our technicians noted:
-
A thick layer of dirt and debris on the condenser fins, reducing airflow.
-
Accumulations of dust and dried mud between the grates.
-
Slowed ventilation causing slight overheating of the compressor.
-
Residues of salt and moisture , typical of ground installations exposed to winter elements.
Without cleaning, these conditions could lead to a loss of energy efficiency and premature wear of the compressor .
Cleaning and maintenance steps
Our AirGreen team undertook a complete and methodical cleaning , in accordance with the manufacturer's guidelines, York, and HVAC best practices.
Step 1: Securing and Inspection
-
Power off via the service circuit breaker.
-
Checking the base and level of the unit (slight tilt due to frost).
-
Airflow analysis and vibration control.
Step 2: Dismantling and removal
-
Removing the top grille and fan to access the condenser.
-
Vacuuming leaves, twigs and dust accumulated at the base of the heat pump.
-
Manual cleaning of corners and joints that are often neglected.
Step 3: Deep Wash
-
Application of a biodegradable, pH-neutral detergent to the condenser fins.
-
Rinse gently with a controlled jet of water to avoid damaging the aluminum slats.
-
Cleaning the fan and the top cover.
-
Localized steam defrosting to eliminate existing frost without thermal shock.
Step 4: Reassembly and testing
-
Reassembly of all components with verification of tightening and alignment.
-
Fan and compressor tested to confirm smooth and quiet operation.
-
Control of refrigerant pressures and discharge temperature.
Results observed after cleaning
The results were immediate:
-
Improved air circulation and return to original performance.
-
Reduced operating noise thanks to a balanced fan.
-
Increased energy efficiency , allowing the customer to reduce their electricity consumption.
-
Prevention of excessive frost , often caused by obstructed ventilation.
The customer noticed from the first few days a more stable heating and a reduction in automatic defrosting time , proof of optimal heat exchange.
