Heat and Energy Recovery Ventilators

In recent years, more and more homes have undergone energy efficiency improvements such as upgraded insulation, improved air sealing and the installation of energy-efficient windows, doors and heating systems.

In many of these homes, air infiltration through doors, windows and other openings in the building shell is random and does not always provide adequate ventilation, which is just as important in a conventional home as in a new home.

Even with an acceptable rate of air exchange, the fresh air may not reach the rooms where it is needed. As a result, mechanical ventilation is needed in many conventional homes to distribute fresh air evenly throughout the home and maintain a healthy living environment. An added benefit of mechanical ventilation systems is their capability to filter the incoming outdoor air.
