Creating a healthy and pleasant indoor environment inevitably requires careful management of air quality. At AirGreen, we understand just how crucial a high-performing HVAC system, especially a central heat pump, can be in purifying the air and ensuring comfort in your home or commercial building across Montreal, Laval, Longueuil, the North Shore and the South Shore. In this article, we share five practical tips based on our field expertise to significantly improve your indoor air quality using a central heat pump.
Optimizing Air Quality: A Matter of Comfort and Health
Air quality isn’t just about comfort—it directly impacts respiratory health, productivity, and even sleep quality. Indoor pollutants – fine dust, spores, allergens, VOCs (volatile organic compounds) – can be effectively filtered by a well-maintained, properly sized central heat pump.
We’ve assisted hundreds of families and building owners with the installation, maintenance, and optimization of their HVAC systems throughout Greater Montreal. Drawing from that experience, we’re sharing five concrete recommendations to help you get the most out of your central heat pump.
1. Choose a Central Heat Pump That Matches Your Space
The first step toward healthy indoor air is having a system that’s tailored to your needs. If it’s too powerful, the unit will cycle too quickly, leading to incomplete dehumidification. If it’s too weak, it will run constantly, wearing out the compressor and letting dust and allergens circulate.
At AirGreen, we always perform a complete heat load analysis for every project in Montreal or beyond, to ensure the system is perfectly sized. For example, a homeowner in Laval contacted us with persistent humidity issues. We replaced their old, improperly sized unit with a Fujitsu 36,000 BTU central heat pump, equipped with a high-efficiency filter. The result: stabilized humidity levels, visible mold reduction, and noticeably better air quality within the first week.
2. Regularly Maintain Filters and Ductwork
Regular HVAC maintenance is essential for preserving air quality. Clogged filters become reservoirs of contaminants. We recommend:
-
Checking filters monthly.
-
Replacing or cleaning them every 2 to 3 months depending on use.
-
Having ducts cleaned every 3 to 5 years—especially if you have pets, have done recent renovations, or deal with frequent dust.
In Longueuil, we recently completed a full duct cleaning in a single-story home equipped with a Goodman R-32 central heat pump. The air was heavy, and the occupants suffered from allergies. After the maintenance, they noticed a significant reduction in symptoms and much better airflow.
3. Integrate a High-Performance Filtration System
Not all central heat pumps are equal when it comes to filtration. Some models, like the Bosch BIVA IDS Premium R-454B, offer multi-stage filtration systems that trap a wide range of pollutants, capturing up to 99% of fine particles.
We recently installed this model in a Montreal duplex where a child with asthma lived. Thanks to its advanced filtration technology combined with a built-in UV system, the air quality improved dramatically. The customer even installed an air quality monitor that confirmed a significant drop in airborne particles.
4. Precisely Control Humidity Levels
Ideal indoor humidity should range between 35% and 50%. Too low, and it causes respiratory irritation. Too high, and it promotes mold and dust mites. Modern central heat pumps regulate humidity automatically thanks to intelligent dehumidification technology.
On the South Shore, a medical clinic was dealing with fluctuating humidity levels that compromised the preservation of certain instruments. AirGreen installed a Lennox Elite 48,000 BTU central heat pump, paired with a central humidifier. The result: stabilized humidity, optimized comfort for both patients and staff.
5. Install an Air Exchanger (HRV/ERV)
Even the best HVAC system can’t prevent CO2, VOCs, or odors from building up if the air isn’t refreshed. That’s why we strongly recommend adding an air exchanger to any central system.
In Sainte-Thérèse, we integrated a Venmar EVO5 HRV with a Trane central heat pump for a family living in a super airtight home. The air, previously stale and dry, became fresher and better balanced—without significant energy loss.
Common Mistakes to Avoid
-
Neglecting maintenance: a poorly maintained heat pump degrades air quality.
-
Installing an oversized model: short cycles hinder proper dehumidification.
-
Forgetting the importance of humidity: a poorly calibrated system can worsen the problem.
-
Not including mechanical ventilation: airtight homes need air renewal.
