Essential cleaning to restore the system's full performance
At AirGreen , we recently performed a complete cleaning of a central heat pump in a Lachine residence, an area where humidity and dust can quickly clog outdoor units. This type of maintenance, often neglected, is crucial for maintaining the system's energy efficiency and extending its lifespan.
Initial diagnosis: accumulated dirt and deteriorated insulation tape
Upon our arrival, we noticed several signs of prolonged neglect :
-
A thick layer of dust and debris on the fins of the outdoor unit.
-
Cracked insulation tape around the refrigeration pipes, revealing traces of moisture.
-
Oxidation residue on the upper fan grille.
-
Exposed electrical connections , poorly protected by old silver tape.
These factors not only reduce the system's efficiency, but also increase the risk of overheating and loss of performance, especially on hot days.
Cleaning and restoration steps
We proceeded according to our professional HVAC cleaning method , respecting safety standards and manufacturer's recommendations.
1. Power off and complete inspection
Before any work was carried out, our technician disconnected the power supply from the disconnect box. A thorough inspection followed to identify any electrical or mechanical anomalies.
2. Cleaning the condenser fins
Using a biodegradable cleaning product and a low-pressure water jet , we removed the dirt and deposits accumulated on the fins. This process allows for better airflow and optimal heat dissipation.
3. Checking the refrigeration connections
The refrigerant pipes were inspected and cleaned, then re-insulated with high-quality insulating tape to prevent any energy loss. The damaged section of the pipe was replaced.
4. Cleaning the disconnect box and wiring
The disconnect box was opened and dusted. The terminals and electrical connections were tightened to prevent intermittent contact and ensure optimal safety.
5. Finishing and performance testing
After a thorough cleaning, we restored the power supply and tested the operating pressure and temperature . The system demonstrated optimal performance, with improved airflow and a noticeable reduction in compressor noise.
Results achieved and benefits for the client
The owner immediately noticed:
-
Improved cooling performance .
-
A reduction in noise during operation.
-
Optimized energy consumption .
-
A cleaner and more professional appearance of the installation.
This type of cleaning not only improves indoor comfort , but also extends the lifespan of the heat pump by several years.
