Does a Wall-Mounted Heat Pump Improve Air Quality?

Hello there, we are AirGreen, your trusted HVAC company in Montreal. We specialize in the sale and installation of wall-mounted heat pumps, also known as mini splits, which provide both cooling and heating features, making them a popular choice for homeowners and businesses in Montreal.

One common question we get asked is, "Does a wall-mounted heat pump improve air quality?" This is a critical question as indoor air quality directly impacts our health and wellbeing. In this comprehensive, detailed, and informative article, we will explore how wall-mounted heat pumps can influence the air quality in your property.

Understanding Wall-Mounted Heat Pumps

Wall-mounted heat pumps, or mini splits, are HVAC systems that offer both heating and cooling solutions for your property. They consist of an indoor unit that is mounted on the wall and an outdoor unit that houses the compressor. These units are linked via conduits that carry power lines, refrigerant tubing, and a condensate drain.

The way heat pumps operate is by transferring heat rather than generating it. During winter, they draw heat from the outside air and transfer it inside. Conversely, in the summer, they remove heat from your home and dump it outside.

The Importance of Indoor Air Quality

Indoor air quality refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Poor indoor air quality has been linked to various health issues such as headaches, fatigue, concentration problems, skin irritation, allergies, asthma, and other respiratory problems.

How Wall-Mounted Heat Pumps Impact Air Quality

  1. Filtration: Most wall-mounted heat pumps come with built-in air filters that can filter out dust, pollen, and other allergens from the air, thus improving the indoor air quality.
  2. Humidity Control: By their very operation, heat pumps help control humidity levels. Excessive humidity can lead to the growth of mold and mildew, which can adversely impact indoor air quality. On the flip side, too little humidity can lead to dry skin and respiratory issues.
  3. Air Circulation: Wall-mounted heat pumps help circulate the air in your home, preventing it from becoming stale and promoting a healthier indoor environment.
  4. No Combustion: Unlike furnaces that burn fuel, heat pumps transfer heat, so there's no risk of carbon monoxide poisoning, a severe indoor air quality concern.

Maximizing Your Wall-Mounted Heat Pump for Better Air Quality

  1. Regular Cleaning: Regularly clean the filters in your heat pump to ensure they continue to effectively filter out contaminants.
  2. Professional Maintenance: Annual professional maintenance can ensure your heat pump is working at its best, promoting good air quality.
  3. Right Size: Make sure your heat pump is the right size for your space. A unit that's too large or too small won't effectively control humidity levels.
  4. Proper Placement: Correct placement of the indoor unit can help ensure optimal air circulation.


A wall-mounted heat pump can indeed help improve indoor air quality in your home or business, not only by conditioning the temperature but also by controlling humidity, filtering out contaminants, and circulating fresh air.
