An essential intervention to restore full performance to an outdoor unit
At AirGreen , we were recently called to Sainte-Dorothée (Laval) for a complete cleaning of a RUUD central heat pump . The client contacted us after noticing that their system was no longer cooling effectively and that an unusual noise was being heard during operation. A quick inspection revealed a significant accumulation of dust, plant debris, and dirt on the outdoor condenser coil, compromising the unit's energy efficiency.
Initial diagnosis: dirt, damaged insulation and loss of efficiency
Upon our arrival, we observed several critical points:
-
A thick layer of dust and pollen covered the condenser fins.
-
The insulation sleeve on the refrigerant lines was damaged and open , allowing condensation to escape.
-
Light corrosion was beginning to appear on some of the unit's metal fasteners.
-
The condenser fan struggled to maintain a constant speed due to accumulated resistance.
These signs explained the overall loss of system performance and increased electricity consumption .
Cleaning and maintenance steps performed
1. Securing and cutting off the power supply
Before any manipulation, we cut off the power supply via the wall disconnect box to ensure a safe intervention.
2. Preparation and complete inspection
We removed the condenser side panels to inspect the evaporator coil , fan fins , and refrigerant connections . A visual and manual inspection identified the most obstructed areas.
3. Low-pressure cleaning
Using a low-pressure, soft water jet and a specialized biodegradable HVAC cleaner , we thoroughly washed the fins and the top grille . This environmentally friendly product effectively dissolves grease and dust without damaging the metal.
4. Restoration of insulation
We replaced the cracked insulating sheath on the copper pipes to prevent heat loss and condensation on the exterior walls.
5. Rinse and dry
A thorough rinse removed all cleaning product residue, followed by a natural drying time to ensure optimal performance.
6. Drainage check
We cleaned the condensation drain , which is often clogged with debris, to ensure proper water drainage. This often-overlooked detail is crucial to prevent leaks into the base of the condenser.
Results after the intervention
As soon as the system was restarted, the airflow became strong and consistent again , the discharge temperature stabilized, and the initial mechanical noise completely disappeared. The customer immediately noticed an improvement in indoor comfort and a reduction in cooling time .
Thanks to this intervention, the RUUD heat pump now operates at its optimal efficiency , extending its lifespan and reducing its energy consumption.
