A new era for indoor air quality and the value of residential and commercial properties
At AirGreen, we witness every day how the integration of an air exchanger into a modern HVAC system transforms both indoor comfort and the real estate appeal of buildings in Montréal, Laval, Longueuil, the North Shore and the South Shore. Much more than a simple ventilation device, the air exchanger has become a strategic asset for property owners who care about air quality, energy efficiency, and the profitability of their real estate investments.
What is an air exchanger and why is it essential today?
An air exchanger is a device that renews a building’s indoor air by expelling stale air while bringing in fresh outdoor air. This process is done by recovering heat from the outgoing air and transferring it to the incoming air, thereby optimizing energy efficiency while maintaining a comfortable indoor temperature.
In cities like Montréal or Laval, where buildings are increasingly insulated for energy savings, indoor air can become saturated with pollutants, humidity, and CO₂. An air exchanger then becomes essential for ensuring constant ventilation without opening windows, especially during winter.
How are air exchangers influencing the real estate market?
Homeowners, buyers, and real estate investors now actively consider the presence of a mechanical ventilation system (MVS) when assessing a property. A home equipped with a properly integrated air exchanger and a modern HVAC system sells faster, at a higher price, and attracts more demanding buyers.
Energy certifications like Novoclimat or LEED require the installation of an air exchanger to obtain their labels, which enhances the perceived value of a property on the market. In addition, some green mortgage loans require a high-performance ventilation system.
Seamless integration: our field-tested approach
At AirGreen, we don’t just sell products: we design tailor-made systems adapted to each type of building. Here's a recent example:
Residential project in Longueuil: maximizing comfort and property value
A duplex owner in Longueuil wanted to improve indoor air quality for his family while preparing to sell the property in the near future. Our team installed a Vanee 160 ECM HRV air exchanger paired with a Bosch BOVA 36 kBTU central heat pump, seamlessly integrated into the existing ductwork.
Challenges encountered:
-
Limited ceiling height in the basement for ductwork.
-
Restricted access to certain closed-off rooms.
AirGreen’s solutions:
-
Installation of insulated flexible ducts to work around ceiling constraints.
-
Addition of air transfer grilles to ensure effective distribution without major renovations.
Result:
-
Notable improvement in air quality, reduced humidity, and Novoclimat certification obtained.
-
The duplex sold 7% above initial valuation thanks to these HVAC upgrades.

Financial incentives available for installing an air exchanger
Thanks to our certified installations, many of our clients have benefited from:
-
The Chauffez Vert program, when the installation is part of an energy conversion project.
-
Novoclimat subsidies for new home construction or major renovations.
-
The RénoVert tax credit (when active) for eco-friendly ventilation projects.
We support you with all administrative steps involved in subsidy applications.
Commercial building installation in Laval: a textbook case
A property manager hired us to improve air quality in a three-story office building in Laval. During winter, the air had become unpleasant, leading to frequent tenant complaints.
We installed three Lifebreath 195 ECM commercial air exchangers connected to a zoned distribution system, with independent control on each floor.
Results:
-
Air exchange rate tripled.
-
Reduction in odors and CO₂ levels measured via sensors.
-
Increased tenant satisfaction and lower turnover rates.
