Ductwork Cleaning, Sealing & Repair — Arlington, TX
Two things matter when you call a ductwork cleaning, sealing & repair: how fast they show up, and whether they fix it the first time. We try hard at both. Our pricing's flat-rate, our techs are state-licensed, and our trucks have parts on them. Most jobs done the same visit.
Local context for Arlington
Most weeks we run 12–18 calls inside Arlington alone. Different houses, similar fixes — we've seen yours before.
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.

One we ran last year
A Arlington customer in their original to home 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 $496 all in.
