How a new HRV system helped several Montréal businesses transform their indoor comfort and cut their energy bills
Across the city of Montréal, several commercial businesses have recently turned to AirGreen to modernize their heat recovery ventilation (HRV) systems. This strategic decision allowed them to boost their energy efficiency while providing a healthier environment for both employees and customers. Here's a detailed look at the significant savings and tangible improvements made possible thanks to these professionally executed HVAC installations by our team.
Why replacing an outdated HRV system can dramatically improve your building’s performance
Old ventilation systems found in many commercial buildings throughout Montréal are often outdated, noisy, inefficient, and no longer capable of maintaining optimal air quality. As these systems age, they tend to consume more energy while delivering less comfort to occupants. By replacing them with a high-efficiency HRV unit, businesses benefit from better temperature control, improved air filtration, reduced heat loss, and, of course, major operating cost savings.
Case Study #1: A care center in Ahuntsic upgrades its HRV with a Venmar E15 ECM
The challenge: A senior care center in Ahuntsic was using a 20-year-old HRV system that no longer met modern ventilation standards. The indoor air was humid and stale, and the energy bills during winter months exceeded $3,000 monthly.
Our solution: We recommended and installed a Venmar E15 ECM, a compact HRV unit with an ultra-efficient ECM motor, delivering a maximum airflow of 160 CFM. With its high-efficiency core and silent operation, this unit is ideal for sensitive environments.
Result: From the first month after installation, the energy bill dropped by 28%, indoor air quality drastically improved, and the staff reported consistent thermal comfort. The business also received a $1,200 grant through the LogisVert program for the North Shore.
Case Study #2: An artisanal bakery in Rosemont improves air quality for its staff
The challenge: In this neighborhood bakery, oven heat, steam, and odors were building up, causing daily discomfort and complaints from staff. Their old rooftop fan offered no real air exchange.
Our solution: We installed a Lifebreath RNC155 HRV unit, known for its efficiency in humid environments. This model handles up to 159 CFM and delivers a 70% sensible recovery efficiency, perfect for removing contaminants and controlling humidity.
Result: After 3 months, excess humidity disappeared, odors were significantly reduced, and employees reported a clear improvement in comfort. In addition to 22% energy savings, the bakery saw a reduction in staff absences related to respiratory discomfort.
Case Study #3: A small office building in Laval boosts its system with a Fantech VHR150
The challenge: A commercial building housing several small businesses in Laval was using an outdated HRV that no longer served the entire building. Complaints about poor air circulation and inconsistent temperatures were becoming frequent.
Our solution: Our team proposed the Fantech VHR150, a highly efficient central HRV unit equipped with two independent motors that adjust airflow based on demand. The unit was installed on the rooftop with a redesigned duct network to efficiently serve every office.
Result: Even temperature throughout the building, continuous airflow, and a 31% drop in heating costs were recorded in the first winter after installation. The projected return on investment is under 3 years.
