Air quality
A clean and contaminant-free HVAC system contributes to better indoor air quality. We eliminate mold, dirt, and harmful particles to provide you with a healthier indoor environment.
Why air quality matters
We spend most of our time indoors, and the air in a closed-up home holds on to dust, pollen, pet dander and other particles. Good filtration helps keep that air cleaner, for your comfort and for your equipment.
HEPA filters
HEPA filters trap a very large share of the fine particles in the air, such as dust and pollen.
UV lights
Installed in the system, ultraviolet (UV) lights help limit the growth of mold and bacteria on its components.
What we do
Humidifiers
Winter air in Montreal can become uncomfortably dry, and indoor heating systems often make it worse. To counteract this, we offer Honeywell humidifiers, designed to:
- Regulate and stabilize humidity levels in your home
- Relieve discomfort caused by dry air
- Improve indoor air quality for a healthier lifestyle
Dehumidifiers
Montreal summers, on the other hand, can become excessively humid, turning your home into a damp environment. Our Clean Comfort dehumidifiers restore comfort by:
- Removing excess humidity
- Preventing mold growth
- Creating a more comfortable and healthier living space
Air exchangers
A sealed home, whether for heating in winter or air conditioning in summer, can become stuffy and uncomfortable. Fortunately, our air exchangers solve this issue by:
- Providing a constant supply of fresh air
- Reducing indoor pollutants
- Enhancing overall air quality
Air purifiers
Concerned about allergens and pollutants in your indoor air? Our Sanuvox air purifiers effectively address these issues by:
- Capturing and reducing airborne contaminants
- Delivering cleaner, healthier air
- Reducing allergy and asthma triggers
Central system filter replacement
Your HVAC filter is its first line of defense. We ensure optimal performance by:
- Providing regular filter replacements every three months
- Offering filters from MERV 8 to MERV 13, 1" to 5" thick
- Enhancing both system efficiency and air quality
Filter sales
We sell replacement filters for your system, from MERV 8 to MERV 13 and from 1" to 5" thick. The higher the MERV rating, the finer the filtration. Tell us which filter you use and we’ll help you find the right one.
Frequently asked questions

Do I need an air exchanger, and which kind?
A well-insulated house holds in moisture and odors: an air exchanger renews the air continuously. A heat recovery ventilator (HRV) warms the fresh air with the outgoing air; an energy recovery ventilator (ERV) also recovers some of the moisture, useful if the air gets too dry in winter. We install Lifebreath, Venmar and Fantech air exchangers. Rénoclimat no longer funds HRVs or ERVs since October 1, 2026, except for a home already evaluated under the old rules. Ask us for a quote.
What humidity should I aim for at home in winter?
About 30% in winter, and 30% or less below −10 °C; never above 45%. Higher, condensation forms on the windows and encourages mold; much lower, dry air irritates throat and skin. A cheap hygrometer will tell you. If the air is too dry, a furnace humidifier helps; too damp in summer, a dehumidifier. Call us to choose one.
My system smells musty: why?
A musty smell often comes from a drain or condensate pan holding water, or dirty coils growing mold and bacteria. A thorough cleaning of the unit usually fixes it. A burning smell, on the other hand, means switching the unit off and calling us right away.
How often should I change the furnace or air exchanger filter, and what happens if I don’t?
It depends on the filter’s thickness: a furnace filter (MERV 8 to MERV 13) usually needs replacing every 3 to 6 months, and the thicker it is, the longer it lasts; an air exchanger’s filter is cleaned as its guide says. A clogged filter lets less air through: dust builds up, the system strains and uses more energy, the air is filtered less well, and a heat pump’s or air conditioner’s coil can freeze. We change it during maintenance, with your filter unless you order one from us before the visit: call us.
