How a Heat Recovery Ventilator Can Save You Hundreds of Dollars a Year (With Real Proof)

Investing in a high-performance heat recovery ventilator is one of the most cost-effective decisions a homeowner or commercial building manager in Montréal, Laval, Longueuil, the North Shore, or the South Shore can make. Too often overlooked, the air exchanger plays a key role in indoor air quality, the longevity of HVAC equipment, and most importantly, in reducing energy costs. At AirGreen, we've seen clients save several hundred dollars a year, simply by integrating a well-chosen air exchanger into their home or building. Here's how, with proof to back it up.

The Air Exchanger: An Invisible but Powerful Ally for Your Savings

A heat recovery ventilator (HRV) allows you to renew stale indoor air while maintaining a comfortable temperature, thanks to heat recovery. In simple terms, the warm air being expelled is used to preheat the incoming cold air, which drastically reduces the load on your heat pump, furnace, or wall-mounted air conditioner.

In an average home in Montréal, this translates to up to 30% savings on heating costs in winter, and up to 20% on cooling costs in summer. These figures come not only from manufacturer studies, but also from the real-world assessments we perform with our customers.


Case Study: Single-Family Home in Longueuil

In a recent project in Longueuil, our team replaced an outdated and inefficient ventilation system with a Venmar AVS N Series heat recovery ventilator (HRV) with a 75% efficiency rating. By optimizing air distribution and integrating a smart control system connected to the Wi-Fi thermostat, the homeowners saw their annual heating bill drop from $2,100 to $1,520, for a net savings of $580 in the first year alone.

Additionally, the occupants reported a significant improvement in comfort and a reduction in humidity and condensation issues.


Why Does a Heat Recovery Ventilator Really Save You Money?

Direct Reduction in Energy Consumption

Every degree recovered through heat exchange is energy your heating system doesn't have to supply. In a region like Greater Montréal, where winter temperatures can drop below -20°C, this optimization results in hundreds of dollars saved annually.

Enhanced Performance of Your HVAC Equipment

A properly installed air exchanger extends the lifespan of your equipment. Fewer heating/cooling cycles, less wear and tear, fewer costly service calls. A client in Laval, who uses a Bosch BOVA central heat pump, avoided more than $400 in maintenance costs over two years simply by adding a high-efficiency air exchanger.

Reduced Air Infiltration

Without proper ventilation, modern, well-insulated homes can develop negative air pressure zones, which cause cold air infiltration. This increases energy loss and destabilizes your indoor environment. The air exchanger, by balancing air pressure, stabilizes indoor temperatures while reducing thermal losses.


What Types of Air Exchangers Maximize Savings?

HRV vs ERV

  • HRV (Heat Recovery Ventilator): Ideal for cold climates like Quebec. It recovers heat from the outgoing air to preheat the incoming fresh air.

  • ERV (Energy Recovery Ventilator): Better suited for very humid environments, as it also balances humidity. Recommended for super-sealed homes or multi-unit buildings.

Choosing the Right Airflow

Poor sizing can ruin your investment. Too small, and it won’t refresh the air sufficiently. Too big, and it wastes energy. That’s why at AirGreen, we always perform a custom airflow calculation (in CFM – cubic feet per minute), based on your square footage, number of occupants, and building insulation.


Financial Incentives and Grants

Government programs like Rénoclimat and Hydro-Québec’s LogisVert grants often provide rebates of up to $650 for installing a high-efficiency air exchanger.

In Sainte-Thérèse, a residential client who opted for a Venmar EVO5 500 HRV received a $480 grant from the provincial program. This assistance reduced the initial cost by 30%, speeding up their return on investment.


Practical Tips to Maximize Your Savings

  • Service your air exchanger annually: clean filters = optimal performance.

  • Pair it with a smart thermostat to adjust airflow based on occupancy.

  • Avoid cheap low-efficiency models (under 60% efficiency).

  • Think about overall insulation: even the best exchanger won’t fix a poorly insulated roof.


Client Testimonial – Montréal, Rosemont District

"We used to have mold in the bathroom, and our electricity bill went over $200 a month. Since installing the Venmar air exchanger, not only is the air fresher, but we’ve reduced our bill by nearly 30%. Thank you to the AirGreen team!"
Jean-Marc D., Montréal
