In many single-family homes in Laval, indoor air quality becomes a real concern as soon as the building envelope is more airtight (renovations, new windows, improved insulation). In Fabreville , we installed a va¦nEE Air Exchanger to ensure constant, controlled, and efficient air renewal—without sacrificing comfort or energy efficiency.
Why install an air exchanger in a house in Laval?
In Quebec, we spend a large part of the year with our windows closed. As a result, humidity builds up, odors stagnate, and certain irritants (fine dust, volatile organic compounds, allergens) remain trapped inside. An air exchanger solves this problem at its source.
-
It extracts stale air (kitchen, bathrooms, utility rooms).
-
It brings in fresh air from outside.
-
It transfers some of the energy from the outgoing air to the incoming air, which helps to reduce heat loss in winter.
It is an ideal solution for achieving a healthier, more comfortable, and better-balanced home in terms of humidity.
The installed system: Air Exchanger va¦nEE (residential)
For this project, we installed a va¦nEE Air Exchanger adapted to a typical Fabreville residence. The size and configuration of the unit are perfectly suited for installation in a technical space (ceiling/attic or mechanical area), with direct access to the ductwork.
When the exact model is not clearly legible in a photo, our approach remains the same: we select and configure the device according to the actual needs of the house (volume of air to be treated, layout of rooms, humidity level, habits of occupants), then we adjust the flow rates for a stable long-term result.
Observable installation details: a clean and durable installation
Several important elements stand out in the installation, demonstrating a design focused on performance and reliability:
-
Insulated ducts (sheathed flexible ducts) connected to the top of the unit: this type of insulation is essential to limit condensation and maintain good thermal stability, especially in winter.
-
Solid mechanical connections on the outlet collars, with a clean finish at the joints.
-
Integrated electrical box and neat low voltage control wiring: good wiring organization simplifies maintenance and reduces the risk of false contacts.
-
Positioning at a height on the structure (ceiling/joists): this frees up floor space, protects the device, and allows for better management of the duct network.
-
Accessibility to the service panel : a key point for maintenance (filters, inspection, periodic cleaning).
At AirGreen, we always emphasize two things: airtight connections and balanced airflow . An air exchanger may look excellent on paper, but it's the quality of the installation and settings that makes the difference in everyday use.
What the customer gains on a daily basis
After commissioning, the impact is generally rapid and very tangible:
-
Fresher indoor air, fewer lingering odors
-
Reduction of excessive humidity (and therefore less fogging, less risk of mold)
-
Improved sense of comfort, especially in the bedrooms and on the upper floors
-
More constant ventilation, without depending on whether the windows are open
-
A house with better pressure “balance” also helps some heating/air conditioning systems to operate more consistently.
Recommended maintenance (simple, but essential)
To maintain stable performance:
-
Check/clean the filters according to the season (often every 3–6 months)
-
Inspect the ducts and grilles as needed
-
Schedule a periodic inspection (especially if the house has a lot of dust, pets, or recent renovations)
A well-maintained air exchanger ensures consistent air quality and significantly improved longevity.
AirGreen in Laval: Residential Ventilation Installation and Optimization
Every house is different: size, number of occupants, level of airtightness, basement humidity, cooking habits, etc. Our role is to configure ventilation for real life , not just “install a box and ducts”.
If you are in Laval (Fabreville, Sainte-Dorothée, Chomedey, Vimont, Duvernay, etc.) and you want to improve air quality, we can offer you a suitable ventilation solution — with a clean installation, precise settings, and a tangible result on a daily basis.
