One we ran last year
Property manager call, Houston-area duplex. Both units had upstairs always 6-8° hotter than downstairs. We pulled the system apart and found crushed flex duct in attic and 30% leakage. Replaced damaged section, sealed remaining ducts, added zone damper, temperature differential dropped to 1-2° on the same trip — both tenants happy. $1674.
What we cover
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.
Houston-area patterns we see
Climate and housing age in Houston tend to drive specific failure patterns. We see the same handful of issues every season.
