Proper ventilation is an important factor in maintaining air flow and humidity levels throughout your home. Home ventilation systems transfer musty, contaminated air from your home to the outdoors. Whole-house ventilators constantly remove the entire volume of polluted indoor air from your home, replacing it with fresh, outdoor air. Ventilators act as a solution to tightly sealed, energy efficient homes, which do not allow much air to escape in order to keep heated or cooled air where it belongs.
Whole-house ventilators are typically sold as heat-recovery ventilators (HRVs) or energy-recovery ventilators (ERVs). Both types of ventilators extract the heating or cooling you have put into your home’s climate before sending the air outdoors. This ensures that your home isn’t wasting energy in the ventilation process.
