Cleaning and Washing of Wall-Mounted Heat Pump in Plateau-Mont-Royal
From foul smells to fresh air — see how our expert cleaning turned a Plateau-Mont-Royal heat pump around!
In summer, the outdoor unit rejects the house's heat outside.

Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
A Fresh Breath of Air for Your Home Comfort System
The Importance of Regular Maintenance
In the picturesque district of Plateau-Mont-Royal, a family recently experienced a significant transformation in their home’s air quality and heat pump efficiency, thanks to the meticulous cleaning services provided by AirGreen. What seemed like a routine cleaning appointment unfolded into a critical intervention, saving the homeowners from potential health risks and system inefficiency.
Unveiling the Hidden Culprit: Mold and Odor
Our journey began when a concerned homeowner reached out about a foul smell emanating from their wall-mounted heat pump. This was not just about a displeasing odor; it was a cry for help from a heat pump struggling to perform its best. On arrival, our AirGreen experts were met with a unit plagued by mold and leakage—common yet dangerous issues that many homeowners overlook.
Step-by-Step Excellence in Cleaning
-
Inspection and Assessment: First, we conducted a thorough inspection to understand the extent of the problem. This step is crucial for crafting a precise cleaning strategy.
-
Internal and External Cleaning: We meticulously cleaned both the inside and the outside units. Removing mold and debris not only eliminates bad odors but also prevents health issues like allergies and respiratory problems.
-
Unclogging the Drain Pipe: Often ignored, a clogged drain pipe can cause water leakage and affect the efficiency of the heat pump. We tackled this head-on, ensuring that the system was leak-free and functional.
-
Final Testing and Customer Walk-Through: Post-cleaning, we tested the unit to confirm that it operated like new. We also took our customer through the process, showing them the before-and-after results, which were nothing short of dramatic.
Beyond Cleaning: Ensuring Long-Term Efficiency
This intervention was not merely about cleaning; it was about restoring and enhancing the life of the heat pump. The homeowner was thrilled to see their heat pump operating efficiently, without the previously persistent odor and leakage. Their satisfaction underscores the importance of professional upkeep and the expertise that AirGreen brings to the table.
