Is your home’s air ready for the Quebec winter?
As winter approaches, many homeowners in Montréal, Laval, Longueuil, the North Shore or South Shore focus on their heating system, insulation, or sealing up windows and doors. But one often overlooked element—essential for both comfort and indoor health—deserves your full attention: your ERV (Energy Recovery Ventilator).
At AirGreen, we’ve found that a significant number of ERV systems across the region are outdated, poorly maintained, or technologically obsolete, which directly affects indoor air quality, home energy efficiency, and the health of its occupants.
Why should you replace your ERV before winter?
1. Instant improvement to indoor air quality
During the winter, we spend up to 90% of our time indoors. A high-performance ERV ensures continuous and efficient air exchange while filtering pollutants, allergens, mold spores, and fine particles.
2. Prevention of moisture and mold
An old or undersized air exchanger can create cold zones and encourage condensation, especially in basements and on windows. This leads to mold, unpleasant odors, and material damage.
3. Lower energy loss
New-generation ERV models, like the Venmar AVS HRV ECM or Lifebreath RNC5, are designed to efficiently recover heat from the exhaust air, significantly reducing energy loss and cutting down your heating bills.
4. Grant eligibility
Replacing your ERV may qualify for local grants, such as the Hydro-Québec LogisVert program, letting you save up to 20% of the installation cost.
