A well-ventilated home is a home built to last
At AirGreen, we firmly believe that high-performance residential ventilation isn’t a luxury—it’s a fundamental necessity to ensure the longevity of your home. High indoor air quality, controlled humidity, and efficient airflow are essential to prevent structural damage, preserve construction materials, and maintain consistent temperatures year-round. Through this exclusive testimonial, we take you inside a project recently completed on the North Shore of Montréal, where our team transformed a family’s daily life by installing a high-performance air exchanger.
Project background: a home in distress
When the Tremblay family from Blainville contacted us, their home was already showing signs of premature wear. Excess condensation on the windows, budding mold in the basement corners, and stagnant odors in certain rooms—all clear signs of inadequate ventilation. Built in the early 2000s, the home was only equipped with a basic ventilation system, without a heat recovery ventilator (HRV). The result: stale, trapped air and constant humidity that were compromising the integrity of the structure.
Technical diagnosis: a customized analysis by AirGreen
Our HVAC specialists visited the site to conduct a complete ventilation assessment. We measured humidity levels, airflow in each room, and observed the home’s thermal behavior at various times throughout the day. The diagnosis was clear: to halt the deterioration, improve quality of life, and extend the building’s lifespan, a high-performance mechanical ventilation system was essential.
The selected equipment: a highly efficient air exchanger
We recommended and installed a VENMAR AVS N SERIES 120 CFM HRV, a unit renowned for its reliability and ability to maintain optimal indoor air quality, even in harsh climates like that of Greater Montréal. This unit offers several advantages:
-
Controlled airflow of 120 CFM, ideal for single-family homes up to 2000 sq. ft.
-
Heat recovery technology with 75% efficiency, allowing for preheating of incoming air in winter.
-
Washable MERV 8 filters, perfect for capturing fine particles, dust, and allergens.
-
Quiet operation, ENERGY STAR certified.
-
Eligible for Hydro-Québec’s LogisVert subsidies, with up to $600 in this specific case.
Installation process: a no-compromise approach
The installation took two days. Our team integrated the system into the existing ductwork, optimizing it to ensure balanced airflow between living spaces and humid zones (bathroom, laundry room, basement). Special attention was given to soundproofing, placing the central unit in the crawl space, and programming the wall-mounted control panel at the main entrance.
Immediate results and long-term effects
Within the first 48 hours, the Tremblay family noticed a radical change:
-
Stagnant odors disappeared
-
Relative humidity dropped to 45%
-
Better sleep quality, thanks to cleaner air
-
Visible reduction of condensation on windows
But the benefits go far beyond these immediate improvements. Controlled and continuous ventilation reduces material wear, prevents infiltration, limits mold growth, and significantly extends the lifespan of the structure. Wood remains dry, walls breathe, and heating systems operate more efficiently.
Customer testimonial: peace of mind restored
“We tried multiple dehumidifiers, but nothing worked long-term. Thanks to AirGreen, our house breathes again. The comfort is unmatched, and now we know our property is in good hands for years to come.”
— Isabelle Tremblay, Blainville, North Shore
Why mechanical ventilation is essential in Québec
In a climate like Montréal’s, where homes are often super-insulated to retain heat, air renewal is frequently overlooked. However, without a high-performance air exchanger, humidity builds up, indoor pollutants stagnate, and surfaces quietly deteriorate. Regular HVAC maintenance and the installation of ENERGY STAR-certified systems help maintain the balance between thermal comfort and building health.
