An essential installation for optimal air quality
At AirGreen , we know that indoor air quality is as crucial as thermal comfort. That's why our teams regularly install and maintain ventilation and air exchange systems in residences across Greater Montreal. We recently completed the installation of a Lifebreath air exchanger in a single-family home in Sainte-Julie , on Montreal's South Shore .
The homeowner had just completed a basement renovation and wanted to improve air circulation throughout the house. Their previous ventilation was inadequate, leading to moisture buildup and lingering odors after showering and cooking. After a comprehensive home assessment, we recommended a Lifebreath HRV air exchanger —a model known for its reliability, energy efficiency, and compact design.
Installation diagnosis and planning
Before any installation, we carry out an analysis of the existing duct network to optimize air distribution. In this specific case:
-
The basement had an ideal technical space for hanging the device.
-
The return air ducts were accessible through the open joist ceiling.
-
The main heating system, an electric hot water tank coupled with a network of metal ducts , allowed for simple and efficient integration.
After validating the plan, our technician chose a suspended installation on chains , a method which ensures better absorption of vibrations and facilitates future maintenance.
Lifebreath Air Exchanger Installation Steps
The installation took place in several precise technical stages:
-
Fixing the suspension system with galvanized chains anchored to the ceiling joists.
-
Connection of insulated flexible ducts (supply and extraction of outside air) using waterproof collars and aluminized tape.
-
Connection of interior conduits to connect the main areas: living room, bedrooms and bathroom.
-
Installation of the condensation drain , essential for evacuating the recovered humidity.
-
Electrical connection and configuration of the wall control panel.
The device was then tested according to AirGreen protocols:
-
Airflow measurement (CFM) at the inlet and outlet.
-
Checking the direction of rotation of the fans.
-
Testing the defrost bypass built into the Lifebreath.
Everything worked perfectly from the first start-up.
Results: healthier air and lasting comfort
The client noticed an immediate improvement :
-
The air in the house is fresher, without feeling heavy.
-
Humidity levels stabilized, even after showering or cooking.
-
The system operates silently, a sign of a precisely calibrated installation .
In addition, thanks to the Lifebreath model's heat recovery, ventilation does not cause any significant energy loss , which translates into long-term savings on heating costs.
