Installing a central air purifier in a Laval home is far from just a techy gadget or luxury item. It’s a real commitment to better living, enhanced protection against airborne pollutants, and long-term indoor comfort. At AirGreen, we recently completed an exemplary project in a bungalow located in the Chomedey neighbourhood, where the primary goal was to improve indoor air quality for a couple—one of whom suffers from chronic asthma. This type of intervention perfectly illustrates how we tailor every HVAC solution to the real needs of our clients.
Why install a central air purifier in a home in Laval?
In a densely populated area like Laval, where allergens, air pollution, humidity, and fine particles can significantly impact health, installing a central air purification system makes perfect sense as a preventive health measure.
Unlike small portable devices, the central air purifiers we install are directly connected to the home’s central ventilation system. This ensures full-home air treatment, guaranteeing even air quality without dead zones.
Project overview in Laval: Installation of a Lennox PureAir S purifier
For this project, our team recommended and installed the Lennox PureAir S, a high-performance model fully compatible with existing central ventilation systems. This central air purifier stands out for its three-stage filtration technology: a MERV 16 filter to capture particles, a charcoal filter for odours and VOCs, and a UVA lamp to neutralize biological contaminants.

Installation steps and challenges
The installation was scheduled after a full inspection of the existing HVAC system. The client already had a Goodman central heat pump previously installed by AirGreen. This made the purifier integration easier, as it was placed in the plenum of the system.
However, one challenge was the limited space in the mechanical room. Our technicians had to develop a custom solution to fit the PureAir S casing without affecting airflow. Thanks to our expertise in custom HVAC installations, the purifier was seamlessly integrated with easy access for future maintenance.
Immediate results after installation
Two weeks after installation, the client reported noticeably easier breathing at night and a reduction in allergy symptoms. The PureAir S system also successfully neutralized persistent odours coming from the kitchen and basement.
This positive feedback clearly demonstrates the true added value of a built-in air purifier: it’s not a gadget, it’s an investment in wellness.
Comparison with other air quality solutions on the market
Our clients in Laval often ask about the difference between a portable air purifier, an air exchanger (HRV), and a central air purifier. Here’s a comparison table we often share:
| Criteria | Portable Air Purifier | HRV Air Exchanger | Lennox Central Air Purifier |
|---|---|---|---|
| Covered area | One room | Whole house | Whole house |
| Effectiveness against viruses/bacteria | Low to moderate | Low | High (99.9%) |
| HVAC Integration | None | Integrated | Fully integrated |
| Maintenance | Frequent | Moderate | Minimal (annual MERV 16 filter replacement) |
| Noise level | Variable | Silent | Silent |
| Cost | Low | Medium | High, but long-lasting |
What to know before installing a central air purifier
AirGreen’s advice for residents of Laval, Montréal, Longueuil, North Shore and South Shore:
-
HVAC evaluation is mandatory: The HVAC system must be in good condition to accommodate a central purifier.
-
Model selection matters: There are several brands (Lennox, Honeywell, Trane). The model must suit your current setup.
-
Strategic placement: The purifier must remain accessible for regular maintenance.
-
Recommended upkeep: One annual maintenance check is enough to keep the system performing well.
-
Realistic budgeting: Expect a cost of $2,500 to $3,200 including installation, depending on your system’s layout.
