Whole house fans are a ventilation solution typically installed in the attic to circulate air within the home by exhausting stale air through a roof vent system and pulling fresh air in through vents, windows, and natural openings in the home’s exterior.
These fans come in various sizes for different-sized homes and have a range of max airflow capacities from 1,200 to 7,600 CFM. Some models feature specialized controllers and sensors for temperature and humidity and can operate intelligently based on the conditions they sense within the home.
