From the books — a recent Las Vegas job
A Las Vegas customer in their 30-year-old home had been chasing upstairs always 6-8° hotter than downstairs for weeks before calling. Crushed flex duct in attic and 30% leakage was the actual cause. We replaced damaged section, sealed remaining ducts, added zone damper, temperature differential dropped to 1-2°; everything stable since. About $540 all in.
What you're paying for
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.
Local context for Las Vegas
