In many homes in Greater Montreal, indoor air quality is becoming as important as thermal comfort. Between accumulated winter humidity, lingering odors, domestic pollutants (from cooking, cleaning products, and building materials), and increasingly airtight homes, a good ventilation system is no longer an "extra": it's a basic requirement.
In this project carried out in Rosemont–La Petite-Patrie , we handled the installation of a va¦nEE Air Exchanger , with a unit from the Virtuo range. The objective: to ensure constant, efficient and quiet air renewal, while maintaining real control over humidity—summer and winter.
Why an air exchanger is becoming essential in Montreal
In Montreal, we experience long periods of heating. As a result, we close everything up, seal everything, and indoor air circulation is poor. Without mechanical ventilation, we often observe:
-
Recurring condensation in the windows
-
Persistent odors (kitchen, bathroom, basement)
-
"Heavy" air in the rooms
-
Humidity poorly managed (too high or too low depending on the season)
-
A feeling of discomfort despite a correct temperature
A well-chosen and well-installed air exchanger allows for continuous air renewal by removing stale air and introducing fresh air, with an approach designed for the Quebec climate.
The installed system: Air Exchanger va¦nEE — Virtuo model
In this installation, the Air Exchanger va¦nEE ( Virtuo series) is a compact residential format, designed to fit into restricted technical spaces (often a mechanical closet or utility room).
What we typically look for with this type of device:
-
Balanced ventilation (controlled air intake and exhaust)
-
Stable operation in cold weather
-
A system that is well maintained (access to service, filters, drainage)
-
A low noise level, especially in condominiums or houses with open-plan living areas
Installation details observed and important technical points
The photo shows a typical “clean” installation in a confined space, with several key elements that make a difference in performance and durability.
1) Installation in a technical closet: space optimization
The unit is installed high up in a utility space (storage/mechanical cupboard type). In this context, our priority is twofold:
-
Maintain adequate service access (panels, filters, maintenance)
-
Prevent the device from interfering with storage or other equipment
We always plan the positioning so that future maintenance doesn't become a headache. An air exchanger isn't something you "install and forget": to remain efficient, it must be accessible.
2) Connection with insulated flexible conduits
We can clearly see insulated flexible conduits (aluminum-coated type). This is a common and sensible choice in residential settings because it:
-
Limits heat loss
-
Reduces condensation on ducts
-
Reduces some of the noise and vibrations
-
Facilitates passage through complex spaces
A critical point: routing and bending. We avoid crushing, excessively tight bends and unnecessary paths, as all of these increase resistance and decrease the actual flow rate.
3) Presence of a control module and a dedicated power supply
The control box visible on the side is an important element: it allows you to manage the ventilation (modes, speeds, sometimes humidistat/timer).
We always ensure:
-
The compliant power supply
-
Clean and secure connections
-
The control logic adapted to the lifestyle (e.g., temporary increase after showering/cooking)
4) Drainage management (condensation)
Condensation is normal on this type of unit, especially in winter. A translucent drain pipe can be seen connected to the base of the unit.
This is a point we take seriously, because improper drainage can lead to:
-
Water accumulation in the unit
-
Odors
-
Risk of overflow
-
Damage to the cupboard and surfaces
We ensure a correct slope, a reliable connection and a durable solution.
5) Vibration reduction and stability
In enclosed spaces, vibrations propagate quickly (walls, shelves, ducts). A professional installation aims to:
-
A stable attachment
-
Minimizing noisy contact points
-
A network of conduits that does not "pull" on the device
The goal: a discreet system for everyday use.
Balance and performance: the difference between "it ventilates" and "it ventilates well"
The most underestimated point is balancing (flow rate balancing). An air exchanger can be brand new and still perform poorly if the flow rates are not adjusted.
At AirGreen, the goal is:
-
A flow rate consistent with the surface area and occupancy
-
A good compromise between comfort, humidity and energy consumption
-
Effective ventilation without over-drying the air in the middle of winter
Proper balancing also helps to limit pressure problems (air “coming in” too much, or on the contrary, air “coming out” too much), which can influence the feeling of drafts and humidity stability.
Expected results for the occupants
After this type of installation, the quickest benefits are usually:
-
Fresher , less "stifling" air
-
Reduction of lingering odors
-
Improved window fog management
-
Improved comfort in bedrooms and enclosed rooms
-
A more stable humidity level, therefore a healthier environment
And above all: a solution adapted to Montreal's climate, where ventilation must be designed for the cold.
Recommended maintenance (simple, but essential)
To keep your va¦nEE Virtuo Air Exchanger performing at its best, we recommend:
-
Check/clean the filters several times a year (depending on dust levels and season)
-
Drain inspection (no blockage, no odor)
-
Periodic checks of the vents (not blocked)
-
More comprehensive maintenance as needed (depending on usage, pets, renovations, etc.)
A well-maintained air exchanger is a quieter, more efficient, and more durable appliance.
Conclusion: a modern, discreet and perfectly integrated ventilation system
In this project in Rosemont–La Petite-Patrie , the installation of the Air Exchanger va¦nEE , Virtuo model, demonstrates exactly what is sought in residential: clean integration, well thought-out distribution, adequate drainage management and an approach oriented towards real comfort.
At AirGreen, we treat ventilation with the same rigor as heating and air conditioning: because breathing clean, well-renewed air is the basis of comfort at home.
