FAQ
How do I know if my ducts are leaking?
Common signs include uneven temperatures room to room, higher bills than expected, dust buildup, or musty odors when the system runs. A pressure test gives a definitive answer rather than guessing.
Does duct sealing help with mold-sensitive homes?
Yes — leaky return ducts are one of the most common hidden contamination paths, pulling unconditioned air (and whatever's in it) directly into your living space. Sealing is often one of the first things we check as part of a mold/CIRS-aware assessment.
