Keep the Air Clean Without Opening the Windows: Modern, Effective Solutions from AirGreen
At AirGreen, we understand how important it is to breathe fresh, clean, filtered air inside your home — especially in Montréal, Laval, Longueuil, the North Shore and South Shore, where extreme weather makes natural ventilation difficult, if not impossible. Closing your doors and windows should never mean sacrificing indoor air quality. That’s why we’ve put together 5 concrete ventilation solutions to ensure optimal air renewal without compromising thermal comfort, safety, or energy efficiency.
Why Is Ventilation Crucial in a Sealed Home?
In modern or well-renovated homes, the building envelope is often extremely airtight — which is excellent for energy efficiency, but not so good for air quality. Without natural air exchange, pollutants (VOCs, humidity, mold, CO₂) can accumulate and negatively impact respiratory health and overall comfort.
Mechanical Ventilation: The Answer to Today’s Indoor Air Challenges
Mechanical ventilation systems are now the standard for continuously bringing in fresh air while maintaining stable indoor temperatures. Here are five high-performing solutions we recommend at AirGreen.
1. Heat Recovery Ventilator (HRV): The Top Choice in Québec
A Standard HVAC Component in Well-Insulated Homes
HRV systems (heat recovery ventilation) are ideal for renewing indoor air without wasting heating or cooling energy. By capturing the heat from stale air before expelling it, these systems can preheat or precool incoming fresh air.
Real Installations by AirGreen
We’ve installed countless HRV systems in Montréal, Laval, Saint-Hubert, Repentigny, and Boucherville, where customers were looking for an efficient ventilation solution for homes sealed tight in winter. For example, in Boisbriand, we integrated a Venmar EVO5 HRV into an existing ductwork system, dramatically improving indoor air quality without raising energy bills.
2. Energy Recovery Ventilator (ERV): More Humidity in Winter, More Freshness in Summer
The HRV Alternative in Certain Conditions
ERV systems work like HRVs but also allow for humidity transfer between outgoing and incoming air. This can be a real advantage during Québec’s dry winters or muggy summers.
Who Is It For?
Perfect for homes on the South Shore dealing with overly dry air in winter or excess humidity in summer. Our team recently installed a Lifebreath RNC205 in a condo in Longueuil, where the residents were experiencing irritation and fatigue caused by dry air.
3. Central HVAC Systems with Integrated Ventilation
All-in-One Comfort and Air Quality Solution
For homes equipped with central systems (heat pumps or furnaces with ducts), it’s possible to integrate ventilation directly into the air distribution network. This allows you to ventilate, heat, and cool using the same ductwork, with centralized control.
A Seamless Integration Example
We recently added ventilation to a Bosch BOVA IDS Premium central system in a home in Rosemère. Thanks to our expertise, stale air was removed without disrupting the home’s thermal balance, while maintaining exceptional energy efficiency.
4. Decentralized Mini Ventilation Systems for Specific Rooms
Localized but Effective
Homes with problem areas — like a windowless bathroom or stuffy basement — can benefit from decentralized mini ventilation systems installed room by room. Compact and efficient, these units can also include HEPA or activated carbon filters.
Custom Installation
At AirGreen, we equipped a home in Laval-Ouest with Aldes EasyHome decentralized ventilation units, targeting a guest bedroom and a windowless bathroom. The result: no more lingering odors, reduced humidity, and improved comfort throughout.
5. Smart Systems with CO₂ and Humidity Sensors
Automate Ventilation for Ongoing Comfort
Some homes benefit from automated ventilation systems, where air renewal happens only when needed. Sensors for CO₂, humidity, or volatile organic compounds trigger the system as required.
The AirGreen Experience
We recently installed this kind of smart ventilation in a home in Saint-Eustache, where the residents wanted an “invisible” but efficient solution. The Broan AI Series system we installed automatically regulates ventilation without any manual intervention.
Maintenance Tips for Your Residential Ventilation System
To stay effective, your system needs regular maintenance to retain performance and prevent dust or contaminant build-up:
-
Clean or replace filters every 3 to 6 months
-
Check intake and exhaust vents
-
Have motors and ducts inspected annually by a professional
-
Monitor indoor humidity levels (ideally between 35% and 50%)
