Ductwork Cleaning, Sealing & Repair — Long Beach, CA
Most Long Beach ductwork cleaning, sealing & repair jobs we see fall into 3 or 4 categories — common stuff, common fixes. Less of a mystery than the marketing makes it seem. Three things you can count on: we show up when we say we will, we quote before we work, and we don't pad the bill.
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.
Local context for Long Beach
From downtown Long Beach to the outer subdivisions, we cover the metro on standard pricing. No travel surcharge inside the service radius.
If you're calling from a property management company, we have separate scheduling and billing for that.
A recent ductwork cleaning, sealing & repair call
Recent Long Beach 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 $1450 — pretty middle-of-the-road for that fix.
