Duct sealing works best in homes where conditioned air is escaping before it reaches your rooms, and most homes along the Wasatch Front qualify. Utah's older housing stock and extreme temperature swings between winter and summer put extra strain on ductwork, widening gaps and cracks over time. If some rooms run hot while others stay cool, or your energy bills climb even with a well-maintained system, sealing your ducts is the fix that stops you from paying to heat or cool air that never makes it inside.
