Benefits of an Air Exchanger
Improved air quality
An air exchanger eliminates excess humidity, odours, smoke, allergens, and other pollutants that accumulate in well-insulated spaces.
Humidity control
By continuously removing humid air, it reduces mold formation and helps prevent condensation issues on windows and walls.
Energy savings through heat recovery
A heat recovery ventilator (HRV) reuses the heat from expelled air to temper incoming air, reducing the load on your heating system.
Ideal for modern, well-insulated homes
The more airtight a home is, the more mechanical ventilation is needed. An air exchanger ensures adequate air renewal in every season without compromising your building envelope's energy efficiency.
What to Consider Before Installation
Choosing the right air exchanger for your home depends on several factors. Our technicians assess your situation on-site before making a recommendation.
Your home's square footage and number of rooms
The capacity of the air exchanger must be matched to your home's square footage and the number of rooms to ventilate. An undersized unit will not renew air adequately; an oversized one can create uncomfortable drafts.
The type of exchanger: HRV or ERV
An HRV (heat recovery ventilator) recovers heat from expelled air to temper incoming air, ideal for cold climates like the Gatineau and St-Isidore region. An ERV (energy recovery ventilator) also transfers humidity, which can be advantageous depending on your situation. Our technicians will help you choose the right type for your home.
Compatibility with your existing ventilation system
Some air exchangers can be integrated into your existing duct network, while others require a standalone installation. The on-site assessment determines the best solution for your configuration.
Your home's airtightness
The more airtight your home is, the more important controlled mechanical ventilation becomes. Recently built homes or those that have undergone significant insulation work benefit particularly from an air exchanger.
Maintenance requirements
An air exchanger requires regular maintenance: filter and heat core cleaning, and duct and airflow verification. Fernand Denis provides air exchanger maintenance as part of its HVAC services.
Your household's specific air quality needs
The presence of allergies, pets, a wood stove, or activities that generate humidity (cooking, bathrooms, basements) influences the type and capacity of exchanger recommended. These factors are taken into account during the on-site assessment.
