Heating And Cooling Distribution If you have hot air heating, it is a good idea to make sure the vents are not blocked or covered by rugs. In most duct systems there are dampers that can be adjusted in the basement trunk lines (see video). These dampers control the amount of air going to different rooms. You can adjust them seasonally if you have central air. What I mean by this is in the summer, you can turn down the dampers that send air downstairs and open up the dampers that send air upstairs (see video). If you live in an older home where the basement is dirty, damp and moldy, you need to seal off the duct penetrations in the basement ceiling (see video) and in basements like this duct sealing becomes more important.
