Breathing clean air inside your home is a basic need that’s often underestimated. Yet indoor air quality can be up to five times more polluted than outdoor air, according to several environmental studies. At AirGreen, we understand that this issue directly impacts well-being, respiratory health, and even the energy performance of your HVAC system. That’s why we offer precise indoor air diagnostics, combined with real solutions like air exchangers, to provide a healthy environment for families across Montreal, Laval, Longueuil, the North Shore, and the South Shore.
An Invisible but Very Real Problem: Indoor Air Pollution
Household pollutants are everywhere: chemical cleaning products, fine particles, excessive humidity, mold, radon, cooking fumes—even construction materials. In a well-insulated home, these particles don’t escape… they accumulate.
The consequences?
-
Chronic fatigue
-
Allergies or asthma attacks
-
Eye and respiratory irritation
-
Frequent headaches
-
Disturbed sleep
In particular, children, the elderly, and sensitive individuals are the first to be affected.
Why Take an Indoor Air Quality Test with AirGreen?
At AirGreen, we’ve developed a comprehensive air quality test, available upon request for all homes served by our team. This test identifies:
-
CO₂ levels (carbon dioxide)
-
The presence of volatile organic compounds (VOCs)
-
Relative humidity (a key source of mold)
-
Fine particles (PM2.5 and PM10)
-
Natural air exchange rate
-
Persistent odors due to poor ventilation
Our certified HVAC technicians use calibrated, industry-standard instruments to establish an accurate diagnosis, then offer a tailored solution.
The Air Exchanger: A Concrete Answer to Household Pollution
The air exchanger is one of the most effective systems for sustainably improving indoor air quality. It continuously refreshes a home’s air while maintaining warmth or coolness depending on the season.
How Does an Air Exchanger Work?
An air exchanger removes stale air (loaded with CO₂, odors, humidity) from areas like the kitchen, bathroom, or laundry room, while introducing fresh outdoor air into living spaces. The system includes a heat recovery core, allowing you to maintain thermal comfort without energy loss.
Concrete Advantages:
-
Elimination of lingering odors
-
Significant reduction of humidity and mold
-
Lower risk of respiratory illness
-
Year-round thermal comfort
-
Improved overall performance of your HVAC system
Case Study: Air Exchanger Installation in Rosemère, North Shore
Recently, we completed an air exchanger installation for a family of four in Rosemère who had been dealing with persistent mold and condensation problems, especially in winter. After conducting an AirGreen test, we found indoor humidity levels above 70% and virtually no natural air exchange.
Our team installed a Venmar EVO5 700 HRV air exchanger, capable of handling 108 CFM with a 75% heat recovery efficiency. The unit includes a MERV 8 filter, ideal for capturing dust and allergens.
Results:
-
Humidity dropped to 48% within the first week
-
Odors disappeared within 48 hours
-
Noticeable nighttime breathing improvement for one of the asthmatic children
-
Heating savings thanks to better thermal distribution
Air Exchanger Maintenance: A Crucial Step Too Often Overlooked
A poorly maintained air exchanger can quickly become ineffective—or even harmful. At AirGreen, we offer annual professional maintenance, which includes:
-
Full duct cleaning
-
Airflow checkups
-
Heat recovery core inspection or cleaning
-
Unit calibration
-
Filter replacement
Our clients in Montreal, Longueuil, Boisbriand, and Boucherville call us back year after year to keep their systems running optimally. A high-performing air exchanger means guaranteed clean air.
Available Grants for Installing an Air Exchanger
You may be eligible for government grants when installing or replacing a high-efficiency air exchanger. For example:
-
Hydro-Québec’s LogisVert Program: for primary residences in Quebec
-
Rénoclimat: up to $650 for improved ventilation
-
Tax credits for energy-efficient renovations
We handle all administrative steps, from technical documentation to submitting applications. Our installations comply with Novoclimat and CSA-F326 standards, ensuring full eligibility.
Our Professional Tips for a Healthier Home Environment
Even without an air exchanger, here are some steps you can take right now:
-
Air out each room at least 10 minutes daily, year-round
-
Use exhaust fans in the kitchen and bathroom
-
Avoid solvent-based cleaning products
-
Never block ventilation grilles
-
Prevent moisture buildup by installing a dehumidifier in basements
But only a properly installed mechanical system ensures constant air renewal—even during Quebec’s coldest winter days.
