How AirGreen Helped a Family in Longueuil Save Over $1,000 a Year Thanks to an HRV

A breath of fresh air for their home: a high-efficiency HRV transformed their daily life in Longueuil

When this family from Longueuil contacted us, they were dealing with persistent issues of humidity, stale air, and rising energy bills. Their single-family home, well insulated but poorly ventilated, showed window condensation as early as fall, a heavy, stagnant indoor atmosphere, and continuously increasing heating costs.

After a full assessment, we recommended the installation of a Venmar AVS N Series heat recovery ventilator (HRV)—a unit well known for its high efficiency and quiet operation. The result? Over $1,000 in annual energy savings and dramatically improved indoor air quality.

Assessing real needs: the first step toward savings

Before any installation, our certified technicians visit the site to assess:

  • The volume of air to be renewed (square footage, number of occupants, closed-off rooms).

  • The level of ambient humidity and any signs of mold or condensation.

  • The heating system already in place (in this case, a central electric furnace).

  • Lifestyle habits (presence of pets, frequency of cooking, etc.).

In this case, the lack of proper mechanical ventilation forced the occupants to regularly open windows, which led to significant heat loss. Thanks to our expertise, we demonstrated that installing a high-efficiency HRV was both eco-friendly and cost-effective.

Choosing the right model: a Venmar AVS N Series HRV perfectly suited for Longueuil

We selected a Venmar AVS N Series model with 130 CFM capacity, offering:

  • 80% heat recovery, certified by HVI standards.

  • A variable-speed ECM motor, using minimal electricity.

  • MERV 8 filter system, easy to maintain and effective against dust and allergens.

  • Noise level under 40 dB, ideal for installation near bedrooms.

This model was fully eligible for Hydro-Québec’s LogisVert program, which provided the family with a direct rebate of $610.

HVAC installation details: efficiency, cleanliness, and discretion

The installation was completed in a single day by our specialized team. Here’s what we did:

  1. Created fresh air intake and exhaust points in the attic, using acoustically insulated ducts.

  2. Integrated the HRV into the existing ductwork without interfering with the central heating system.

  3. Mounted the HRV on anti-vibration brackets to reduce mechanical noise.

  4. Tested airtightness and balanced airflow rates, with fine adjustments for each area of the house.

Thanks to this custom installation, no noise is perceptible in the living spaces, and the indoor air is automatically renewed without any heat loss.

Tangible benefits: quality of life and savings from the very first month

Just one month after the installation, the family noticed:

  • Condensation on windows completely gone.

  • Improved breathing and better sleep, especially for the child with asthma.

  • A drop in their electricity bill of nearly $120.

  • A fresher, drier, and more comfortable air throughout the home.

Over the course of a year, savings on heating and ventilation exceed $1,000, while offering enhanced comfort and healthy air quality—a must for an active family.

Why this type of project works particularly well in Longueuil

Longueuil experiences a typical Greater Montréal climate: cold winters, humid summers, and highly variable autumns. This kind of weather encourages moisture buildup inside well-insulated homes. Moreover, a large portion of homes built before 2000 were not equipped with controlled mechanical ventilation.

Our many HRV installations in Longueuil, Saint-Hubert, and Boucherville confirm that this kind of project provides a fast return on investment, along with a significant boost in comfort.

Practical tips for anyone considering an air exchanger

If you’re on the fence, here are a few common mistakes to avoid:

  • Choosing a unit without having your specific needs evaluated.

  • Installing an HRV without properly balancing the airflow.

  • Skipping regular maintenance (filters, ducts).

  • Ignoring the opportunity to receive Hydro-Québec subsidies.

At AirGreen, we provide full support: free assessments, detailed quotes, certified installation, and fast after-sales service.

Conclusion: a smart installation with measurable results

Thanks to our work in Longueuil, this family now enjoys a healthy, comfortable, and energy-efficient environment. The HRV installed by AirGreen doesn’t just circulate air—it actively helps reduce energy expenses, improves residents' health, and adds value to the home.
