Cleaning a Panasonic outdoor heat pump in Brossard

Essential winter maintenance to preserve performance and durability

Even in the depths of a Quebec winter, an outdoor heat pump continues to play a crucial role in home comfort. At AirGreen , we provide professional cleaning of outdoor units , which are often exposed to dust, snow, and debris.
Recently, our team intervened in Brossard , on the South Shore of Montreal , to perform a complete cleaning of a Panasonic outdoor wall-mounted heat pump installed on a red brick facade.

Symptoms observed before our intervention

The owner contacted us after noticing several problems:

• The unit was making a louder noise than usual , especially during defrosting.

• The front grille was partially obstructed by dust and windblown debris.

• The hot air inside seemed less constant , indicating a loss of efficiency in the thermodynamic cycle.

• A thin layer of frost was accumulating abnormally on the fan .

These signs suggested general fouling of the condenser and reduced airflow — a common problem for outdoor heat pumps that have not been cleaned for more than a year.

Technical inspection and preparation for intervention

Before any operation, our certified technicians carried out a complete check :

• Visual inspection of the condenser and fins ;

• Fan rotation test to ensure that no obstruction is hindering the motor;

• Checking the drainage of the condensation tray ;

• Control of wiring and protected electrical connections in the rear housing.

The unit was then switched off and protected with a waterproof cover to prevent any water from entering the electrical circuits.

Complete cleaning process

1. Defrosting and manual debris removal
   We first removed the accumulated snow around the device and gently defrosted the fins using hot air blown at a controlled temperature, without ever using a metal tool.

2. Condenser cleaning with water under controlled pressure
   The condenser, the central part of the outdoor unit, was cleaned using a low-pressure water jet to remove fine dust and pollutants accumulated between the fins.
   We used a biodegradable cleaning product specifically designed for aluminum surfaces, guaranteeing optimal results without corrosion.

3. Gently brush the fan and the housing.
   The fan was carefully brushed to remove the ingrained dirt on the blades, which is often a source of imbalance and vibration.
   We also cleaned the crankcase and front grille to restore smooth airflow.

4. Rinse and dry thoroughly
   After cleaning, the unit was rinsed with clean water and then left to dry naturally. A compressed air blower was used to remove any remaining moisture around the connections.

5. Recommissioning and performance testing
   Once everything was completely dry, the Panasonic heat pump was put back into service. Pressure and temperature measurements confirmed a significant increase in energy efficiency and a reduction in operating noise .

Results and benefits after cleaning

At the end of the procedure, the difference was remarkable:

• Airflow restored to 100% .

• Faster and quieter defrost cycle .

• Energy consumption reduced by nearly 10%.

• No residual vibration on the wall mount.

The client, impressed by the level of detail in our work, chose to add an annual AirGreen maintenance contract , guaranteeing the longevity and performance of their system throughout the year.

Why entrust the cleaning of your outdoor heat pump to AirGreen?

An outdoor heat pump operates year-round and is subjected to the harshest conditions: wind, rain, dust, pollen, snow, and ice. Without regular maintenance , the fins become clogged, the compressor overheats, and energy consumption quickly skyrockets.

At AirGreen , we use certified, safe and environmentally friendly cleaning methods :

• Biodegradable products that respect the environment and health.

• Specialized equipment for gentle cleaning without damaging the fins.

• Checking the drainage, fan and electrical connections .

• A detailed post-intervention report is provided to the client.

Thanks to this expertise, our customers benefit from a system that breathes better, consumes less and lasts longer.

AirGreen recommendations for preventative maintenance

To guarantee the performance of your outdoor unit:

• Clean the snow and leaves around the device at least once a month in winter.

• Never obstruct the front grille with objects or plants.

• Schedule a professional cleaning in the spring or fall.

• Avoid uncontrolled high-pressure cleaning , which can bend the fins.

We operate throughout Montreal, Laval, Longueuil, on the North Shore and the South Shore , with local teams trained for each type of residential or commercial installation.

AirGreen , an expert in Panasonic heat pump maintenance and cleaning , is committed to maintaining the performance, safety and durability of your HVAC systems, even in the most demanding climatic conditions in Quebec.
