A Gleaming Transformation: From Grime to Shine
At AirGreen, we pride ourselves on delivering exceptional HVAC service that speaks volumes about our commitment to quality and customer satisfaction. Our recent project in Rivière-des-Prairies–Pointe-aux-Trembles involved an intense cleaning and maintenance operation on a wall-mounted heat pump that had certainly seen better days. What we discovered when we first arrived was a machine in desperate need of some professional care. Here’s how we turned this grimy unit into a model of efficiency and cleanliness.
The Initial Inspection: Facing a Heavily Soiled Challenge
When we first examined the unit, it was clear that this wasn’t a routine job. Dust and grime had built up thickly on the internal components, and the evaporator coils were clogged, impacting the unit’s performance. The fan blades were coated with layers of dirt, and the drainage system appeared to be in distress. Our technician team quickly realized that a deep, thorough cleaning was essential to restore this unit to optimal operation.
The Cleaning Process: Our Proven Step-by-Step Approach
Our cleaning service isn’t just about appearance; it’s about performance and longevity. Here’s how we tackled this wall-mounted heat pump:
- Protective Setup: We carefully set up protective plastic sheeting around the unit to catch all runoff water and debris. We believe in leaving a home as clean—or cleaner—than we found it, so preparation is key.
- Deep Foam Cleaning: We applied a high-grade cleaning foam to the coils and blower wheel. This foam penetrates deeply, breaking down dirt and grime that regular cleaning can’t reach. The image you see above showcases the foam in action, doing its job as it seeps into every crevice.
- Drainage System Flush: We made sure to thoroughly clean out the drainage system, which is crucial for preventing water leakage and mold growth. Our technicians use specialized tools to ensure that all blockages are eliminated.
- Freon Level Verification: As part of our comprehensive service, we also checked the refrigerant levels. The correct amount of Freon is vital for efficient cooling and heating, and our inspection ensures the system runs at peak performance.
- Filter Cleaning and Replacement: The air filters were not only dirty but also close to their lifespan limit. We gave them a complete cleaning and advised the homeowner to consider replacements for optimal air quality.
The Results: A Pristine Machine and a Happy Customer
By the time we finished, the wall-mounted heat pump was practically glowing. The coils were spotless, the fan blades were free of grime, and the unit was draining water efficiently. We conducted a performance test, and the difference was immediately noticeable. The airflow was stronger, and the cooling power had significantly improved. Our customer was thrilled, expressing sincere appreciation for our attention to detail and the clean state of their machine.
Why Proper Maintenance Is Crucial
Cleaning a heat pump isn’t just about aesthetics; it’s about keeping your home’s air quality top-notch and ensuring energy efficiency. A dirty unit works harder to cool or heat your space, leading to higher energy bills and unnecessary wear and tear. Here’s why regular maintenance is vital:
- Energy Efficiency: A clean heat pump uses less energy, which translates to lower utility bills.
- Improved Air Quality: Dirty filters and components can lead to the circulation of allergens and pollutants.
- Extended Lifespan: Routine maintenance prevents costly breakdowns and extends the overall life of the unit.
The Tools of the Trade: Our Secret to a Sparkling Finish
We utilize top-of-the-line cleaning solutions and advanced tools, such as foam applicators and high-pressure drainage cleaners. Each step is meticulously planned to ensure maximum impact with minimal disruption. Our technicians are trained to handle every type of wall-mounted unit, from the oldest models to the latest smart systems.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.
In summer, the outdoor unit rejects the house's heat outside.
Generic illustration of this type of installation, not a survey of this job site. Tap a number.
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.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the indoor unit's filters.
- Clear leaves and debris left on the outdoor unit by winter.
- Test cooling before the first hot days.
- Clean the filters more often when the unit runs a lot.
- Keep plants away from the outdoor unit.
- Check that no water drips from the indoor unit.
- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.
- Book periodic maintenance before winter.
- Keep snow away from the stand and the front of the unit.
- Let the unit defrost: it is normal.
- Never hit the ice on the fins; call us if the unit stays iced up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In heating mode, the outdoor unit can produce water.
During defrost cycles. That water must drain away without forming ice.
2. You pick the capacity with a simple square-footage rule.
Windows, insulation, orientation and how the room is used all count. Capacity is chosen on site.
3. A multi-zone connects several indoor heads to a single condenser.
One head per room, all on the same condenser. Each room keeps its own temperature.
4. The disconnect can sit behind the patio furniture.
It must stay accessible: it is what shuts the unit off for service.
