Controlled ventilation is the process of supplying a house or room continuously with fresh air. Ventilation reduces excess moisture and unhealthy indoor air pollutants. Properly designed and installed ventilation increases home comfort. The best way to ventilate your home is with a Heat Recovery Ventilation (HRV) system. This system consists of four basic parts:
- a means of exhausting stale air and excess water vapor
- a means of supplying fresh air
- a way of distributing the fresh air throughout the house
- controls for operating the ventilation system
To maximize the benefits of your HRV, it is strongly recommended to have it properly installed by an HRAI certified installer.
