Invisible comfort, yet essential: when indoor air quality becomes a health issue in Montreal
At AirGreen, we know that a wall-mounted or central air conditioner isn’t just a comfort appliance for hot days. It’s also a true public health tool that directly contributes to indoor air quality, and therefore to your everyday well-being. In Montreal, where heatwaves are becoming more frequent and where urban buildings often trap humidity, it’s crucial to understand the fundamental role of your air conditioning system in your living environment.
The air conditioner: a shield against invisible particles and allergens
A well-installed and well-maintained air conditioner acts as a silent filter against fine particles, pollen, mold spores, and dust circulating in our homes. Our clients in Montreal, Laval, Longueuil, the North Shore, and the South Shore confirm it: an effective HVAC system significantly improves their breathing and sleep, especially during smog episodes or seasonal changes.
In a recent installation on the Plateau-Mont-Royal, we replaced an old, inefficient wall-mounted unit with an ultra-quiet FUJITSU KZAH R-32, 12,000 BTU, equipped with an advanced filtration system. The result? The client, who suffers from allergic rhinitis, reported a significant decrease in symptoms and told us she was “finally breathing clean air in her condo, just like in the countryside.”
Cleaner air also means controlled humidity levels
Beyond temperature, a good air conditioner also regulates indoor humidity levels. Too much humidity leads to mold, respiratory irritation, and an overall sense of discomfort. This is a major issue in typical Montreal and Laval homes, which are often poorly ventilated.
During a service call in a duplex in Saint-Henri, our team installed a Bosch BIVA IDS Premium R-454B central system with 24,000 BTU. This unit not only lowered the ambient temperature by 5°C, but also maintained humidity between 40% and 50%—the optimal range for respiratory health. The client told us their sleep quality, as well as their children’s, had radically improved.
The right unit makes all the difference
At AirGreen, we guide our clients through choosing the ideal air conditioner, based on surface area, layout, potential sources of indoor pollution (furniture, pets, smoking, humidity), and of course, budget.
Here are a few examples of installations that reflect our approach:
-
Montreal-North: Installation of a Sharp ZU1 wall-mounted 18,000 BTU, featuring low-impact R-32 refrigerant, in a semi-basement prone to humidity. Result: purified, dry, and cooler air.
-
Longueuil: Setup of a Goodman R-32 central system, 36,000 BTU, in a family bungalow. The equipment, combined with a smart thermostat, ensures perfect indoor climate control with an integrated HEPA filter.
-
South Shore (Brossard): Replacement of an obsolete unit with a FUJITSU KZAH R-32 wall-mounted system, offering dual filtration (ionic and mechanical) in a home with two long-haired pets.
HVAC maintenance: the key to clean air every day
Even a high-performance air conditioner needs regular maintenance to retain its filtering properties. Our HVAC maintenance services in Montreal and surrounding areas include:
-
Full filter cleaning
-
Duct disinfection
-
Humidity drainage inspection
-
Air quality sensor checkups (for newer models)
In Villeray, we performed maintenance on a Gree Lomo wall-mounted unit installed two years prior. The client had reported stale-smelling air. Upon inspection, the HEPA filter was clogged. Once replaced, clean airflow was restored instantly.
What are the real health and lifestyle benefits?
Medical studies show that a good air conditioning system reduces:
-
Asthma and allergy episodes
-
Eye and nasal irritation
-
Headaches linked to poor air quality
-
Heat stress in the summer, especially for the elderly
At AirGreen, we’ve seen these results among dozens of families in Laval, Montreal, and the North Shore, who told us their comfort was transformed after installing their new HVAC unit.
Grants available to make clean air accessible
Thanks to Hydro-Québec’s LogisVert program, many of our clients have been able to obtain between $1,700 and $2,500 in grants for installing high-efficiency systems. These incentives are available to residents of Montreal, Longueuil, Laval, the North Shore, and the South Shore, depending on eligibility criteria.
We assist every client step by step with preparing their grant applications, providing all required technical documents, detailed invoices, and energy efficiency proofs (SEER, HSPF, etc.).
