Proper ventilation in Longueuil is much more than a residential luxury
At AirGreen, we know that many homeowners in Longueuil and the surrounding areas have questions about residential ventilation. Far too often, misleading information circulates and prevents people from making the right decisions for their comfort, health, and wallet. In this article, we debunk three persistent myths surrounding ventilation in homes, drawing on our hands-on field experience and numerous ventilation system installations in Longueuil, Montréal, Laval, the South Shore and the North Shore.
Myth 1: “My house is well insulated, so I don’t need ventilation”
What we often see on the ground is that thermal insulation is confused with indoor air quality. A well-insulated home is great for keeping heat in during the winter and cool air in during the summer. But it also means the air circulates less efficiently. The result? A buildup of humidity, CO₂, dust, VOCs (volatile organic compounds), and sometimes even mold.
During a recent installation of a central ventilation system with a Venmar EVO5 500 HRV air exchanger in a single-family home in the Saint-Hubert neighborhood of Longueuil, our client believed that their home didn’t “need” mechanical ventilation due to a recent energy-efficiency renovation. However, tests showed humidity levels above 65% and very poor air renewal. After the installation, comfort was immediately improved: fresher air, fewer allergens, and a significant reduction in persistent odors in certain rooms.
Good insulation without controlled ventilation becomes a trap for air quality.
Myth 2: “Ventilation systems are too noisy and consume a lot of electricity”
This is a common misconception we regularly work to correct. The modern air exchangers and controlled mechanical ventilation (CMV) systems installed by AirGreen are designed to be quiet, efficient, and low-consumption.
Take the example of our work on a semi-detached house in Longueuil, on Montarville Street. We replaced an old, noisy fan with an Aldes InspirAIR Home 160 air exchanger. Thanks to its high-efficiency ECM motors, the new system consumes only 24 W in standard mode—equivalent to an LED lightbulb. As for noise? Barely 0.3 sones. The clients called us a week after the installation: they had forgotten the unit was even running, it was so quiet.
The era of energy-hungry, noisy fans is long gone.
Myth 3: “Installing a ventilation system is too expensive for what it brings”
Nothing could be further from the truth when you consider the real benefits of proper ventilation: reduced humidity, better respiratory health, mold prevention, increased property value, and lower heating and cooling costs over time.
In 2024, several subsidies are available to encourage the installation of energy-efficient systems. For example, Hydro-Québec’s LogisVert program offers attractive financial incentives for the installation of heat recovery ventilation systems (HRV/ERV).
One of our clients in Longueuil, located in the Vieux-Longueuil sector, received $870 in assistance for the installation of a Lifebreath 195 ECM HRV, helping to cover a significant portion of the initial investment. This installation also helped reduce their heating costs by 12% the following winter, thanks to efficient heat recovery.
