A complete cleaning operation by AirGreen for optimal performance
At AirGreen , every HVAC system cleaning is more than just maintenance: it's a complete energy overhaul. Our team recently traveled to Brossard , on Montreal's South Shore , to perform a complete cleaning of a Goodman central heat pump . This type of service is essential to maintain the efficiency, durability, and air quality of a heating and cooling system used year-round.
Initial diagnosis: dust accumulation and decreased efficiency
The client contacted us after noticing:
-
Uneven heating performance during cold days;
-
An abnormal noise coming from the outdoor unit ;
-
And a recent increase in electricity consumption .
During the inspection, our technician noted:
-
An air intake grille obstructed by dust and residue;
-
Dirty condenser fins , preventing proper heat dissipation;
-
And traces of moisture and light oil around the case, a sign of increased mechanical stress.
The unit, located in a semi-open residential environment, was exposed to fine dust, leaves and insects accumulated over the seasons.
AirGreen Cleaning Steps
1. Securing and cutting off the power supply
Before any manipulation, we disconnected the power supply to ensure a safe intervention . The unit was carefully disassembled to access each critical component.
2. External dust removal and fan cleaning
Using a compressed air blower and a soft, antistatic brush , we removed the debris stuck to the protective grille and the fan blades. This meticulous work restored free airflow.
3. Condenser cleaning
The external heat exchanger was then treated with a biodegradable cleaning product specifically for HVAC systems , allowing grease and fine particles to dissolve without damaging the aluminum fins.
A low-pressure water jet was then applied to rinse thoroughly, taking care not to bend the fins.
4. Checking the drain and the junction box
The condensation drain was inspected and flushed to prevent any backflow. We also checked the connections of the electrical cables and refrigerant lines to ensure the system's integrity before restarting.
5. Post-cleaning performance test
Once the cleaning was complete, the unit was powered back on. The results were immediate:
-
Enhanced and more homogeneous airflow ;
-
Stable temperature during internal blowing;
-
Reduced noise level thanks to decreased air resistance.
Results: restored efficiency and comfort
After the service, the Goodman heat pump regained its original efficiency. The customer noted quieter operation and improved temperature stability throughout the house.
The perfectly clean fins now allow for better heat dissipation , reducing the compressor load and extending its lifespan.
Why an annual cleaning is essential
A poorly maintained central heat pump can lose up to 30% of its efficiency over time. The consequences:
-
Increase in electricity costs;
-
Premature compressor wear;
-
Reduced interior comfort;
-
And risks of abnormal noises or overheating.
At AirGreen , we recommend a complete professional cleaning every year , carried out by qualified technicians. This allows for:
-
To ensure optimal energy efficiency ;
-
To improve indoor air quality ;
-
And to extend the lifespan of the HVAC system .
