In Montréal and Surrounding Areas, an HVAC Solution That Truly Works Against Pollen and Indoor Allergens
With the arrival of spring or fall, many residents in Montréal, Laval, Longueuil, the North Shore, and the South Shore see their allergy symptoms flare up: sneezing, nasal congestion, itchy eyes or throat. In response, many turn to a central heat pump as a potential solution. But what’s the reality? Is it a durable, effective response to seasonal allergies, or just another tech fad? At AirGreen, we’ve explored the question through hundreds of real HVAC installations and customer testimonials.
Understanding the Link Between Indoor Air Quality and Allergies
Pollen, fine dust, mold spores, dust mites, and other airborne particles are the main allergy triggers inside homes. They enter through:
-
Open windows
-
Clothing or shoes
-
Pets
-
Unfiltered air leaks
In fact, indoor air can be up to five times more polluted than outdoor air, especially in poorly ventilated homes. That’s where a well-configured central HVAC system becomes a true asset.
How Can a Central Heat Pump Help Reduce Allergy Symptoms?
Continuous Air Filtration
Central heat pumps continuously circulate air through high-performance filters. Unlike wall-mounted units, they:
-
Filter 100% of indoor air volume
-
Trap fine particles, pollen, pet dander
-
Limit allergen recirculation in ductwork
-
Maintain consistent temperature and humidity levels
Integration of HEPA or MERV-13+ Filters
At AirGreen, we recommend adding HEPA or MERV-13+ filters during installation. These filters capture:
-
99% of allergenic particles larger than 0.3 microns
-
Mold spores
-
Airborne bacteria and viruses
-
Odors and VOCs (volatile organic compounds)
Humidity Control
Air that’s too dry or too humid promotes allergen growth. Central heat pump HVAC systems maintain ideal indoor humidity between 40% and 50%, which:
-
Reduces mold growth
-
Limits dust mite survival
-
Improves respiratory comfort for occupants

Caution: Not All Systems Are Created Equal
Some wall-mounted heat pumps or portable devices marketed as “purifiers” offer limited effectiveness against allergens. Our recommendations:
-
Avoid units that don’t support MERV-13 or HEPA filters
-
Prioritize ducted systems for centralized filtration
-
Don’t rely solely on washable filters
-
Check the unit’s ability to regulate humidity within ideal ranges
