A modern ventilation solution for better indoor air quality
In a home located in Villeray–Saint-Michel–Parc-Extension in Montreal , our AirGreen team recently completed the installation of a Lifebreath air exchanger . This type of device is essential in modern homes, particularly those with high-performance insulation, because it ensures constant and healthy air renewal.
The project was carried out in a utility space adjacent to the laundry room, combining technical efficiency with visual discretion. This approach perfectly illustrates our expertise in residential ventilation systems adapted to Montreal's urban context.
Choosing a Lifebreath air exchanger
The Lifebreath brand is renowned for its heat recovery ventilation (HRV) and energy recovery ventilation (ERV) systems . In this project, the installed unit allows:
-
To replace stale air with fresh outside air, while reducing heat loss.
-
Improve indoor air quality by removing humidity, pollutants and odors.
-
To optimize the energy efficiency of the home thanks to the integrated heat recovery system.
-
To meet Quebec standards regarding mandatory mechanical ventilation in new or renovated homes.
Technical details of the installation
The installation of this HVAC system was carefully planned and executed to fit harmoniously into a confined space, here the laundry room.
Main elements of the installation:
-
Wall Mounted : The Lifebreath exchanger has been securely mounted to the wall, above the appliances, to maximize the use of available space.
-
Insulated flexible ducts : connected to the device, they ensure optimal air circulation between the interior and exterior while reducing heat loss.
-
Secure power supply : direct connection to a dedicated outlet, complying with safety standards and facilitating future maintenance.
-
Convenient Access : Positioning allows occupants and technicians easy access to filters and components for simplified maintenance.
Comfort and health for occupants
Thanks to this installation, the customer benefits from:
-
Healthier indoor air , essential in an urban environment like Montreal.
-
A reduction in excessive humidity , limiting the risk of mold.
-
An improvement in energy efficiency , since the heat from the stale air is recovered to preheat the incoming air.
-
A discreet solution, integrated into a space already dedicated to domestic equipment.
Why install an air exchanger in Montreal?
In a city like Montreal, where winters are harsh and homes are often very insulated, natural ventilation by opening windows is rarely sufficient. Installing a Lifebreath air exchanger allows you to:
-
Maintain a balanced humidity level all year round.
-
Meet the requirements of energy efficiency grant programs.
-
Contribute to the overall comfort and health of occupants, particularly in dense urban environments.

What we check on a job like this one
Each number is a point we check on site. Switch between summer and winter to watch air and heat move.

It removes stale air and brings in fresh air. The two airflows cross in the core without mixing.
It recovers part of the heat from the outgoing air to temper the incoming air. Depending on the model, it also manages humidity.
An outdoor hood, kept away from the exhaust so the house does not pull back the air it just removed.
Humid, stale air leaves through its own hood, fitted with a damper.
The ducts that connect to the outside are insulated to prevent condensation inside the house.
Stale air is drawn from humid rooms and fresh air is sent to living areas. The airflows are balanced.
It sets the mode and speed. You use it more when the house is humid or full of people.
Depending on the model and the season, the core produces condensation, removed through a drain with its loop.

Check what applies at your place. A "no" is not a refusal: it is what we sort out during the estimate.
Good habits, once the unit is in place
Six simple habits that keep the unit going. Your list stays on this device.
What to do, season by season
Three habits per season for this unit. They take a few minutes and prevent many calls.
- Clean the filters and core as the manufacturer specifies.
- Check the outdoor hoods: nests, debris, dampers.
- Lower the speed if the outdoor air gets humid.
- Adjust the speed to the humidity in the house.
- Check that the drain flows.
- Keep the outdoor hoods clear.
- Clean the filters before the closed-house season.
- Check the exhaust damper.
- Book a full cleaning if the unit has not had one in a long time.
- Clear snow from both outdoor hoods.
- Raise the speed if condensation appears on windows.
- Let the unit run: with the house closed, humidity builds up.
The right pages, at the right time
Four statements: true or false?
It all comes down to details you have just seen.
1. In an air exchanger, fresh air and stale air mix.
The two airflows cross in the core without mixing.
2. The two outdoor hoods must be kept apart.
Otherwise the exchanger pulls back the air it just removed.
3. An air exchanger can help with condensation on windows.
It renews the air and helps keep humidity in the right range.
4. An exchanger never needs maintenance.
Filters and core get dirty and need regular cleaning.
