Nashville ductwork cleaning, sealing & repair
About a third of ductwork cleaning, sealing & repair calls in Nashville turn out to be something the homeowner could fix in 10 minutes with a $12 part. We'll tell you which third. Free dispatch in business hours. After-hours fee folded into the job price if you accept the quote.
The actual work
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 Nashville
Nashville's housing market has us seeing a lot of move-in inspections and "the previous owner did what?" calls. We sort them out.
On bigger jobs we'll bring two techs. On simpler ones, just one — fewer hands, faster billing.
Recent service example
Last spring we got a call from a homeowner near the south Nashville. Upstairs always 6-8° hotter than downstairs. Diagnosis: crushed flex duct in attic and 30% leakage. We replaced damaged section, sealed remaining ducts, added zone damper, temperature differential dropped to 1-2°, ran the test, and were out the door in the same visit. Total: $1334 including parts.
