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.
Why Proper Maintenance of Your Mini-Split Heat Pump is Crucial for Performance
When it comes to ensuring the longevity and efficiency of your mini-split or wall-mounted heat pump, routine maintenance isn't just an option—it’s a necessity. At AirGreen, we specialize in the meticulous cleaning, washing, and maintenance of mini-split heat pumps, ensuring that our customers experience optimum performance all year round.
Our Latest Mini-Split Heat Pump Cleaning in Lachine, Montréal
Our recent job in Lachine, Montréal, is a perfect example of the attention to detail we bring to every project. This particular mini-split was long overdue for a thorough cleaning, and we were up for the challenge! The homeowner had noticed that their system wasn’t working as efficiently as it once did. They were experiencing reduced airflow, inconsistent temperatures, and even an unpleasant odor when the unit was running. That's when they turned to AirGreen for our professional mini-split cleaning services.
The Cleaning Process: From Grime to Shine
1. Initial Inspection: Evaluating the Condition
The first step in any cleaning job is a thorough inspection. We carefully examined the interior and exterior of the mini-split unit, identifying areas with the most significant buildup of dirt, dust, and even mold. This inspection allows us to create a customized cleaning plan tailored to each unique situation.
2. Deep Cleaning the Filters and Coils
The most critical part of any mini-split cleaning is addressing the evaporator coils and air filters. Over time, these components accumulate dirt, which not only reduces efficiency but can also lead to unpleasant odors. We meticulously removed the filters and cleaned them using a specialized cleaning solution designed to break down the toughest grime. The evaporator coils were carefully washed, ensuring any dust and debris that had collected over time were thoroughly removed.
3. Attention to the Blower Wheels and Louvers
The blower wheels and louvers are often neglected during regular maintenance but are vital for ensuring the even distribution of air throughout your home. As shown in the image above, these components had accumulated a significant amount of dirt, restricting airflow and reducing the system’s overall efficiency. We carefully cleaned each louver, ensuring they moved freely and the air could circulate as intended.
4. Sanitizing the Interior: Eliminating Mold and Bacteria
One of the most critical aspects of mini-split maintenance is addressing potential mold and bacteria growth within the unit. This is especially important in humid climates, like Montréal. We used an eco-friendly, yet highly effective, sanitizing solution to eliminate any mold spores and bacteria, ensuring the air quality in your home remains clean and healthy.
5. Testing and Fine-Tuning: Ensuring Optimal Performance
After cleaning, we conducted a series of tests to ensure the mini-split was running at its peak efficiency. This included checking the refrigerant levels, examining the electrical connections, and testing the airflow. By the time we were finished, the mini-split was operating as if it were brand new!

- Rake the leaves around the outdoor unit.
- Test heating before the first cold days.

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.
