Indoor air quality is essential for our comfort, health, and everyday well-being. Yet, in many homes across Montréal, Laval, Longueuil, the North Shore, and the South Shore, air quality is often overlooked. At AirGreen, we know just how much of a difference a properly installed and well-maintained wall-mounted heat pump can make in purifying indoor air while ensuring year-round comfort. Here are five practical, real-world tips based on our field experience to help you improve the air quality in your home using your wall-mounted heat pump.
Optimize Your Wall-Mounted Heat Pump to Purify Indoor Air
A wall-mounted heat pump does much more than heat or cool your space. Many of the latest models, including units from Fujitsu, Gree, Tosot, and Sharp, are equipped with advanced filters that capture fine particles, allergens, and even certain bacteria.
Why does this matter?
During a recent installation in Longueuil, we equipped a condo with an 18,000 BTU FUJITSU KZAH wall-mounted heat pump, a unit featuring a long-life ion filter. The homeowner had mild allergies, particularly in the summer. Just three weeks after installation, she reported a significant improvement in her breathing and overall comfort. We get feedback like this regularly.
Tip #1: Choose a model with HEPA filters, ion filters, or activated carbon to maximize indoor air filtration.
Never Skip the Maintenance of Your Heat Pump
A poorly maintained unit becomes a breeding ground for dust, mold, and dust mites. Worse, it significantly reduces your system’s energy efficiency.
A real-life example:
We recently performed a full HVAC cleaning in Laval on a 24,000 BTU Gree Extreme wall-mounted heat pump installed in a family home. After several years without maintenance, the filters were black, and the evaporator was clogged. After the deep cleaning, not only was the unit’s energy performance restored, but the family also noticed the house smelled fresher and there was noticeably less dust in the air.
Tip #2: Clean your filters every 2 to 3 months and schedule a full professional maintenance at least once a year.
Use Your Heat Pump’s Dehumidifying Function
Excess humidity is a major threat to indoor air quality. It promotes mold growth, especially in older homes in Montréal or poorly ventilated basements.
Our work on the South Shore:
In a Brossard home, we installed an 18,000 BTU Gree Sapphire wall-mounted heat pump. The basement was often damp, especially in spring. By using the dehumidifying function, humidity levels dropped from 70% to 45%, eliminating mold stains on the walls.
Tip #3: Activate the dehumidifier mode on your wall-mounted heat pump, especially in spring and fall, or if you notice condensation on your windows.
Install Your Wall-Mounted Heat Pump in a Strategic Location
The position of your wall-mounted unit directly affects how purified air circulates in your home. Poor placement leads to stagnant air and dust buildup in certain areas.
A case we handled in Montréal:
During a job in Rosemont, our AirGreen team was called in after a poorly positioned unit left the living room overly warm and dry, while the bedrooms remained cold. We repositioned the unit to ensure even airflow and improved filtration in the main rooms. The result: better comfort and healthier air circulation throughout the home.
Tip #4: Let our AirGreen technicians assess your space to ensure an optimal HVAC installation.
Make Your Wall-Mounted Heat Pump Part of a Whole-Home Air Quality Strategy
A wall-mounted heat pump is a powerful tool, but it should be part of a full system that includes ventilation, purification, and humidity control.
Example in Sainte-Julie:
In a South Shore home, we paired a 12,000 BTU Tosot wall-mounted heat pump with a Venmar air exchanger. The homeowner wanted to eliminate cooking smells and improve air quality for their baby. The result: a consistently fresh, clean, and healthy indoor environment.
Tip #5: Consider combining your HVAC system with an air exchanger—especially in newer, tightly sealed homes.
Common Mistakes to Avoid with Your Wall-Mounted Heat Pump
-
Using the system without checking or cleaning the filters
-
Blocking the wall unit with furniture or curtains
-
Ignoring warning signs like unusual noises or smells
-
Hiring unqualified installers
At AirGreen, we often get calls to fix improperly done installations, especially in Laval and on the North Shore, which ends up costing clients much more in the long run.
