FAQ

Can I reuse my old ducts with a new system? Often, yes, if they're the right size and in good shape. We check them during the estimate.

Can you add ducts to a house that doesn't have any? Sometimes, depending on attic, basement and closet space. If not, a ductless mini split is usually the better route.

Will new ductwork make my home quieter? Properly sized ducts usually reduce air noise and whistling.
