Does HVAC do exhaust fans?

Yes, HVAC systems can include exhaust fans. Exhaust fans are used to remove stale air from a room or building and replace it with fresh air from outside. They are typically used in bathrooms, kitchens, and other areas where odors or humidity need to be removed. Exhaust fans are also used to help reduce the amount of heat in a room or building, as well as to reduce the amount of dust and other airborne particles.
