Tangibly reduce your environmental impact through advanced ventilation
At AirGreen, we understand that lowering your carbon footprint starts with tangible actions at home. One of the most effective—and often overlooked—ways to achieve this is by installing a modern air exchanger, such as an HRV (Heat Recovery Ventilator). In a climate like Greater Montréal, where harsh winters demand intense heating and indoor air quality often suffers, a well-selected HRV offers a dual solution: enhancing indoor comfort while cutting energy consumption.
In this article, we’ll explain how an HRV works, why it’s a powerful step toward energy transition, and how AirGreen has already implemented these solutions in homes across Montréal, Laval, Longueuil, the North Shore, and the South Shore.
What is an HRV and how does it work?
An HRV (Heat Recovery Ventilator) is a mechanical ventilation system designed to provide continuous air renewal in your home. Stale indoor air is extracted from high-humidity areas (bathroom, kitchen, laundry room), while fresh air is supplied to living spaces (living room, bedrooms), with minimal heat loss thanks to a thermal exchanger.
The heat from the extracted air is transferred to the incoming fresh air, reducing the need for additional heating during cold seasons. In addition to ensuring high indoor air quality, an HRV enables substantial energy savings.
Why installing an HRV is an eco-responsible choice
Direct reduction of CO₂ emissions
Heating accounts for a significant portion of greenhouse gas emissions in Quebec households. By reducing the heating load required to maintain indoor temperatures, an efficient HRV significantly lowers the CO₂ emissions associated with your home.
Improved overall energy efficiency
Modern, well-insulated homes often lack proper ventilation, despite being airtight. An HRV bridges that gap without needing to open windows, thereby avoiding heat loss.
Better comfort and health
Excess humidity, mold, allergens, and indoor pollutants negatively impact your quality of life. By maintaining optimal humidity levels and cleaner air, the HRV contributes to a healthier and more comfortable home, while aligning with sustainable living goals.
Case Study: Installation of a Venmar EVO5 700 HRV in Laval
At AirGreen, we recently installed a Venmar EVO5 700 HRV in a single-family home in Chomedey, Laval. While the house was well insulated, it suffered from persistent window condensation, mold in the bathroom, and generally stale indoor air.
Challenges faced:
-
Limited attic access for ductwork installation;
-
Requirement for low noise operation;
-
Compliance with strict energy efficiency standards.
AirGreen’s solution:
We selected the Venmar EVO5 700 HRV, a high-efficiency unit with an ultra-quiet ECM motor, offering over 75% heat recovery. With meticulous planning, we installed insulated ducts in critical zones without compromising existing insulation. The system was integrated with the central thermostat, enabling smart, automated ventilation control.
Results:
-
Noticeable reduction in indoor humidity within the first week;
-
Perceptible improvement in indoor air quality;
-
15% drop in the household energy bill the following month.
How to choose the right HRV for your home
1. Proper sizing for your home
An undersized air exchanger won’t provide adequate airflow. An oversized unit wastes energy. We always conduct a personalized assessment of your home to recommend the right model.
2. Energy recovery efficiency (SRE)
The higher the Sensible Recovery Efficiency, the better the performance. Top-of-the-line models reach up to 85% heat recovery.
3. Quiet operation
Modern models from brands like Venmar, Lifebreath, or Aldes are engineered for quiet residential performance.
4. Simplified HVAC maintenance
A good HRV should be easy to maintain: washable filters, accessible components, and automated maintenance alerts. At AirGreen, we offer customized HVAC maintenance plans with automatic reminders.
Available subsidies and eco-friendly incentives
Various provincial and federal subsidies are available to help finance part of your installation, especially through programs aimed at improving residential energy efficiency in Quebec.
Currently, several programs are available for residents of Montréal, Laval, Longueuil, the North Shore, and the South Shore, including those offered by Hydro-Québec, Transition Énergétique Québec, and local municipalities. We help you prepare and submit your grant application, free of charge.
