In many homes in Fabreville, Laval , indoor air can quickly become too humid in winter (condensing windows, lingering odors, a feeling of stuffiness) or too dry/uneven depending on the use of the bathroom, kitchen, and basement. This is exactly the kind of situation where a properly sized and installed air exchanger makes all the difference.
At AirGreen , we recently installed a va¦nEE Air Exchanger , a residential unit designed to provide continuous and stable mechanical ventilation , while improving indoor air quality and everyday comfort. In this project, the unit (from the VIRTUO range, as identified on the device) was seamlessly integrated into the air distribution system via a duct network, with particular attention paid to accessibility, airtightness, and actual performance in the field.
Why install an air exchanger in a house in Laval?
Greater Montreal's climate is demanding: doors and windows remain closed for long periods, limiting the supply of fresh air. As a result, CO₂ , humidity, odors, fine particles, and household pollutants accumulate. An air exchanger acts like a "lung" for the home:
-
Constant air renewal (stale air exiting / fresh air entering)
-
Humidity reduction in sensitive areas (basement, bathrooms)
-
Improved stability of indoor comfort (less stagnant air, fewer odors)
-
Health support (particularly for allergies, irritations, and headaches related to stuffy air)
The installed system: Air Exchanger va¦nEE (VIRTUO series)
The photo clearly shows a suspended metal box with its ventilation connections. This format corresponds to a typical residential air exchanger installation (HRV/ERV depending on the configuration), designed to operate efficiently for several years with simple maintenance.
Even when a device performs well on paper, it's the quality of the installation that determines the result: noise, actual flow rate, balance between incoming and outgoing air, condensation, pressure losses, etc. This is precisely where our AirGreen approach makes the difference.
Visible installation details and technical choices (which makes for a “clean” installation)
1) Unit suspended on chains: stability + vibration reduction
The Air Exchanger va¦nEE is installed in a suspended position , which helps to:
-
to limit the transmission of vibrations to the structure,
-
preserve access to the ducts and the casing,
-
facilitate maintenance (filters, periodic cleaning, inspection).
2) Mixed conduit network (rigid + insulated flexible) for efficient distribution
We observe:
-
sections of rigid galvanized conduit (robust, good performance),
-
insulated flexible conduits (often used for certain sections to absorb vibrations and manage more complex routes).
The key here is to avoid common mistakes: excessively long flexible hoses, tight elbows, crushing, or poorly sealed transitions. An air exchanger needs to breathe properly: every restriction increases noise and reduces airflow.
3) Sealing and joints: a critical point often overlooked
We see sealed joints and tight fittings. Good sealing allows for:
-
to maintain actual throughput at the expected level,
-
to reduce performance losses,
-
to avoid air leaks that create noise, dust, and imbalance.
4) Wall control/command (blue display): simple daily operation
A dedicated control (visible on the side) makes it easy to:
-
the choice of speeds,
-
supplementary modes (e.g., boost after shower/cooking),
-
a stable and logical use for the occupants.
Expected result: a healthier, more comfortable home, better protected in winter
In an area like Fabreville , where many properties have basements, enclosed technical areas, and intensive heating use in the cold season, a properly installed air exchanger quickly provides tangible benefits:
-
less condensation on the windows
-
reduction of persistent odors,
-
Indoor air is "lighter" and more breathable.
-
better humidity management (therefore less risk of mold in the long term),
-
more consistent overall comfort from one floor to another.
Our AirGreen method: real performance, not just “plugged in and done”
For each Air Exchanger va¦nEE installation, we aim for three objectives:
-
Flow rates consistent with the reality of the house (and not theoretical values)
-
Durable installation : sturdy supports, easy access, clean and airtight conduits
-
Comfort and discretion : reduced noise, optimized ductwork, meticulous finish
Recommended maintenance (simple, but essential)
To keep your air exchanger in top condition:
-
Check/clean the filters periodically.
-
inspect the ducts (dust, condensation),
-
Ensure that the outside air inlets/outlets are unobstructed.
-
perform preventative maintenance when necessary (especially before or during winter).
