While all vents in your house move air, vent types differ according to function and location. The HVAC system in a typical residence moves more than 1,500 cubic feet of air per minute. This airflow passes through a variety of vent types as air volume is continuously circulated throughout the house and then back to the furnace or air conditioner. Here’s how to tell the difference between the various vent types in your home:
These are vent types that deliver heated or cooled air to individual rooms through supply ductwork.
Return vents are under negative air pressure to draw conditioned air out of a room. Return air is pulled through return ductwork back to the furnace or air conditioner to be filtered, then heated or cooled again.
Typically installed in the ceiling of bathrooms and kitchens and controlled by a timer, exhaust ventilation is a one-way process that incorporates a powered fan to pull humidity and odors out of a single room. Exhaust airflow goes through a dedicated exhaust duct to the exterior of the house.
