On the South Shore, concerns about indoor air quality are becoming increasingly important for homeowners and condo dwellers. Poor ventilation can not only affect comfort but also harm the respiratory health of occupants. At AirGreen, we understand that not every family has the budget for a complete overhaul of their HVAC system. That’s why we’re presenting 5 affordable ventilation solutions that can truly make a difference—without breaking the bank.
Why invest in indoor ventilation?
The air inside a home can be up to five times more polluted than the outdoor air. On the South Shore, where residential density is high and humidity levels fluctuate with the seasons, poor ventilation leads to a buildup of mold, dust, and volatile organic compounds (VOCs). These contaminants are invisible, but their effects are very real: allergies, headaches, chronic fatigue, and respiratory irritation.
Our ventilation service calls on the South Shore have proven that you don’t need a major overhaul to significantly improve indoor air quality. Here are five effective and accessible upgrades you can consider starting today.
1. Installing a High-Efficiency Air Exchanger (HRV or ERV)
Estimated budget: between $1,200 and $2,500 (including installation)
This is one of the best ways to improve indoor air quality without replacing your entire system. A Heat Recovery Ventilator (HRV) or Energy Recovery Ventilator (ERV) removes stale indoor air and brings in fresh outdoor air. It retains heat in the winter and moisture in the summer, helping to lower energy bills.
What we do at AirGreen:
On the South Shore, we recently installed a Venmar EVO5 700 HRV air exchanger in a home in Brossard. The family was dealing with excessive humidity in the bedrooms, especially during winter. After the installation, their windows stopped fogging up and cooking odors were more effectively eliminated.
2. Adding High-Performance Ventilation Outlets in Closed Rooms
Estimated budget: between $150 and $400 per room
Closed rooms or basement bedrooms are often poorly served by central ventilation systems. Installing modern air vents with adjustable flow control improves airflow balance throughout the home. This helps better distribute fresh air and reduce stale air buildup.
Field example:
In Longueuil, a client had persistent odors in a basement office. We installed a directional Zephyr air vent with a backdraft damper. The result: improved airflow and the odors were gone within the first week.
3. Full Professional Duct Cleaning Service
Estimated budget: between $400 and $800 for a standard home
Ducts collect dust, allergens, pet hair, bacteria, and mold. A complete cleaning helps restore smooth and healthy airflow. This service should be done every 5 to 7 years.
What we observed:
During a service call in Saint-Jean-sur-Richelieu, our technicians removed over 3 kg of dust and debris from a 20-year-old house. After our cleaning, the residents reported an immediate improvement in air quality and fewer allergy symptoms.
4. Integrating UV-C or HEPA Air Purifiers into Existing Systems
Estimated budget: between $500 and $1,200 depending on the model
These purifiers are installed directly into the central ventilation system. UV-C lamps destroy bacteria, mold, and viruses, while HEPA filters trap fine particles and allergens.
A model project:
In Saint-Lambert, a family with a child suffering from asthma reached out to us to install a Lennox PureAir purifier in their HVAC system. Since then, nighttime asthma attacks have significantly decreased.
5. Optimizing the Ventilation System through Rebalancing
Estimated budget: between $250 and $600
Often overlooked, this service consists of measuring and adjusting air pressure and flow in each room to ensure a more even and efficient distribution. It’s a simple way to optimize an existing system without replacing it.
AirGreen service call:
In La Prairie, a client complained about an overly hot living room in summer and a freezing bedroom in winter. After a full rebalancing done by our certified technicians, we corrected the imbalance by adjusting airflow in each vent. Immediate comfort, with no major expenses.
