‘Tis the warming season! Leaky ducts = an easy fix. Last time you put boxes in the attic, did you feel the cool air leaking from the ductwork? You could be feeling 30% of your air conditioning right there! When the weather cools, buy a can of goopy mastic, and take an old paint brush up to the attic with you. Apply to any seams, over any silver tape, and to any rips in the ductwork. What about the light you saw coming through a crack from the room below? Your best friend is called “Great Stuff” and it comes in a spray can in the insulation aisle. Pull back the insulation from the crack, spray and wait for it to dry, then push back the insulation. Cheap and easy!
