HVAC DUCT PENETRATIONS

Your HVAC system heats and cools your home. But if it's not sealed properly, it might be working a lot harder than it needs to. Check the areas where the HVAC ducts enter your living space. Typically, these ducts extend from the basement through the first floor. Seal between penetrations and ductwork from the basement.

Remember: anytime you're working overhead, position yourself in such a way that you are not applying directly above your head.
