Existing home vent a hood, little one fan thing, that is ducted to the outside.
about 14 yr old house.
I feel the nice cold artic air coming in when it is not running.
Not being a mechical person, what do they do now a days to prevent the cold air from entering the house.
I know on bathroom exhaust there is a one way flap.
thanks
