Unless the ductwork in your home is newly installed by a trusted HVAC company or has been inspected recently, you might be losing energy through your duct system. Ductwork is one of those quiet and largely unseen aspects of our homes that we tend to pay little attention to until the problems they’re causing get big enough to affect our comfort, health and energy bills.
