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 Comprehensive HVAC Cleaning Service You Can Trust
At AirGreen, we pride ourselves on delivering top-tier HVAC services throughout Montréal, Laval, Longueuil, the North Shore, and the South Shore. Recently, our dedicated team completed a mini-split cleaning and maintenance project in Côte Saint-Luc, providing a fresh new start for a wall-mounted heat pump system. While our cleaning services might seem like a routine job, we always make each installation unique and ensure it's an enjoyable experience for both our customers and ourselves.
The installation in Côte Saint-Luc is a perfect example of how we go beyond the surface to optimize system performance and keep homes comfortable year-round. This job involved thorough cleaning, inspection, and servicing of a wall-mounted mini-split heat pump—a crucial step in ensuring optimal energy efficiency and prolonged equipment lifespan.
The Importance of Regular Cleaning
Heat pumps, especially mini-splits, are often the unsung heroes of modern climate control systems. They work quietly, cooling and heating homes without much fuss. However, without regular maintenance, these systems can lose efficiency, leading to higher energy bills and a compromised indoor environment.
This project in Côte Saint-Luc involved the meticulous cleaning of both the interior and exterior units of the wall-mounted mini-split. While these systems are highly efficient, they tend to accumulate dust, mold, and debris over time. This not only reduces airflow but can also lead to foul odors and poor air quality inside the home.
Why is this so important?
- Improved Air Quality: Cleaning ensures that dust, dirt, and mold aren't circulating in your home.
- Enhanced System Efficiency: A clean unit runs more smoothly, consuming less energy and reducing utility bills.
- Extended Equipment Lifespan: Regular maintenance helps prevent major breakdowns and extends the life of your HVAC equipment.
The Story Behind the Installation
Our client, a long-time resident of Côte Saint-Luc, reached out to AirGreen with concerns about unpleasant odors coming from their mini-split unit and decreased cooling performance during the warmer months. After a brief consultation, we scheduled an in-depth cleaning and maintenance visit. Upon arrival, our technicians quickly assessed the situation and began the cleaning process, which included:
- Disassembling the indoor unit for access to the air filters, evaporator coils, and fan blades.
- A thorough wash of the air filters, which had accumulated a significant amount of dust and pollen.
- Cleaning and disinfecting the evaporator coils to prevent the buildup of mold and mildew, ensuring that the air being circulated is fresh and healthy.
- Inspecting the drainage system to ensure no blockages were present, which can cause water leaks and damage to walls and floors.
- A detailed cleaning of the outdoor condenser unit, removing leaves, dirt, and debris to improve heat exchange efficiency.
What sets AirGreen apart is the attention to detail that our technicians bring to every project. The cleaning process took a few hours, but by the end of it, the mini-split unit looked as good as new and was performing better than ever. The client could immediately feel the difference in air quality and efficiency.
What Makes Our Service Unique?
We understand that every home is different, and so are the heating and cooling needs of every client. In this particular case, the mini-split unit was relatively new, but it hadn't been serviced in over a year. This led to clogged filters and a diminished airflow, which is a common problem for many homes that overlook regular HVAC maintenance.
At AirGreen, we don't just provide a quick clean-up. We educate our clients about the importance of ongoing system maintenance, making sure they know the benefits of scheduling regular cleanings. Here's why our approach is different:
- Expert Technicians: Our team is certified, experienced, and passionate about what they do. They leave no stone unturned when it comes to ensuring your system is in perfect condition.
- Advanced Tools and Techniques: We use the latest equipment and eco-friendly cleaning solutions to get the job done without harming your system or the environment.
- Personalized Service: We take the time to understand your system's specific needs, tailoring our services to provide maximum efficiency and longevity for your equipment.
The Benefits of Regular Mini-Split Maintenance
For our Côte Saint-Luc client, the benefits of this cleaning were immediate. Not only did the unit begin to run more quietly, but the cooling power was also noticeably stronger. Regular maintenance of mini-split systems offers a number of advantages, including:
- Better Energy Efficiency: A clean system doesn't have to work as hard, saving you money on your energy bills.
- Improved Airflow: Dust and debris can block airflow, making your system less effective. Regular cleaning ensures consistent performance.
- Healthier Indoor Air: By cleaning the filters and coils, we remove harmful pollutants that can aggravate allergies or respiratory issues.
- Reduced Risk of Breakdowns: Regular cleaning and inspection help identify potential issues before they become major problems, saving you money on costly repairs.
- Increased System Longevity: A well-maintained system can last years longer than one that is neglected.

The unit we serviced in Côte Saint-Luc is a high-efficiency wall-mounted heat pump designed to handle the extreme temperature variations typical of the Montréal area. This mini-split system is known for its whisper-quiet operation, compact design, and impressive energy savings.

- Energy Star certified, ensuring top-tier energy efficiency and savings on your utility bills.
