🛠️ Inspection Find of the Week
Despite the name… duct tape isn’t actually designed for ductwork. 😄
Over time, standard duct tape dries out, loses its adhesive, and can peel away from heating and cooling ducts. That can allow conditioned air to escape, reducing your HVAC system’s efficiency and increasing energy costs.
For sealing metal ductwork, foil HVAC tape or mastic duct sealant are the proper materials because they’re made to withstand the temperature changes found in duct systems.
It’s a small detail, but it’s one of those things we keep an eye out for during a home inspection.
Have you ever noticed duct tape being used where it shouldn’t be?
