What's typical for this job
Most homes have leaky ducts losing 20-30% of conditioned air to attics and crawl spaces. Sealing the duct system is the highest-ROI HVAC improvement most homeowners can make.
We test ducts with a blower door + duct blaster, identify leaks, and seal them with mastic (better than tape long-term) or aeroseal injection.
Full duct replacement is rare — only on systems with collapsed flex-duct, severe pest damage, or major redesign needs. More common: targeted replacement of damaged sections plus sealing of the rest.
Louisville-area patterns we see
Newer Louisville construction tends to be on slab foundations with PEX. Easier access in some ways, more code-current in others.
That said, newer construction in Louisville has its own set of typical issues. We see both.

Got a call last month from a the outskirts Louisville home — 20-year-old build. Symptom: upstairs always 6-8° hotter than downstairs. Cause: crushed flex duct in attic and 30% leakage. Replaced damaged section, sealed remaining ducts, added zone damper, temperature differential dropped to 1-2°, all done in the same visit, billed flat-rate at $312.
