Older Sacramento neighborhoods often have galvanized service lines or clay sewer laterals from the original build. Different prep, different tools.
Recent service example
Recent Sacramento job: upstairs always 6-8° hotter than downstairs in a original to home home. We replaced damaged section, sealed remaining ducts, added zone damper, temperature differential dropped to 1-2° after diagnosing crushed flex duct in attic and 30% leakage. Cost ran $540 — pretty middle-of-the-road for that fix.
What this service includes
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.
