Why Lewisville Homeowners Choose Frosty's for Ductwork Services
The elevated humidity near Lewisville Lake creates additional challenges for ductwork in Lewisville homes. When conditioned air leaks out through gaps in the duct system, warm, humid attic air gets pulled in — creating condensation inside the ducts that promotes mold and mildew growth. Frosty's HVAC addresses both the mechanical problem (leaking connections) and the biological consequence (mold risk) during every Lewisville ductwork evaluation.
Lewisville's mix of housing ages means duct conditions vary widely. Castle Hills homes may have relatively modern ductwork, while Highlands and Valley Vista homes from the 1980s-1990s often have deteriorating flex duct that's been baking in 140°F+ attic heat for 30+ years. We assess each home individually and recommend the minimum intervention that solves the problem.
Our approach is honest: if sealing ($350) will fix the issue, we won't push replacement. If multiple runs need replacing ($700/run each), we'll show you the evidence and explain the cost-benefit. We want your trust for the next 20 years, not a single oversized invoice today.

Can ductwork cause mold in my Lewisville home?
Yes. The combination of leaky ducts and Lewisville's lake-proximity humidity creates ideal conditions for mold growth inside duct systems. We inspect for mold during evaluations and recommend remediation if found.
How old is too old for ductwork in Lewisville?
Flex duct in Texas attics typically needs attention at 15-20 years and replacement by 25-30 years. If your Lewisville home was built before 2000, your ductwork likely needs at least evaluation and sealing.
