Duct Replacement & Ductwork Services in the East Bay
Your ducts are half your HVAC system — and in many East Bay homes, they're the neglected half. Leaky, crushed, undersized, or badly routed ductwork wastes the air you've paid to condition, pulls dusty attic and crawlspace air into your home, and makes even a brand-new system underperform.

Why Oren's HVAC Services for ductwork & duct replacement
Oren's HVAC Services tests, repairs, seals, redesigns, and fully replaces residential ductwork across Alameda and Contra Costa County. The East Bay's older Oakland, Berkeley, and Alameda housing stock has duct work from every era — and we fix the actual problem instead of selling bigger equipment to push through bad ducts.
The fix equipment can't deliver
A bigger AC can't fix ducts that leak a third of their air into the attic. Duct repair often delivers more comfort per dollar than any equipment upgrade — and we'll tell you when that's your situation.
Testing first, recommendations second
We inspect and assess your duct system before recommending anything — and we show you what we found, in plain photos and plain language.
Sealing, repair, or full replacement
Sometimes sealing and a few repairs solve it. Sometimes decades-old ducts in an older East Bay home need to go. We quote the honest option, not the expensive one by default.
Better air, not just better airflow
Sealed, properly insulated ducts stop pulling dust, insulation fibers, and attic air into your living space — a real air quality upgrade that pairs naturally with filtration work.

Popular service areas
Ductwork & Duct Replacement — common questions
How do I know if my ducts are leaking?
Telltale signs: uneven rooms, dusty vents, and high bills. We confirm with a physical inspection of the duct runs, connections, and insulation — and show you exactly what we find before quoting anything.
Should I replace my ducts when I replace my HVAC system?
It's the right time to evaluate them — the crews are already there. If your ducts are sound, we'll say so. If they'll choke your new system, replacing them protects the bigger investment.
Is duct sealing worth it, or is replacement always better?
Sealing is genuinely effective when the duct material itself is sound — it's a fraction of replacement cost. When ducts are deteriorated, undersized, or badly routed, sealing is a band-aid. Our assessment tells you which side you're on.
Do bad ducts affect air quality?
Significantly. Return-side leaks pull unfiltered attic or crawlspace air — dust, fibers, humidity — straight into your system and your lungs. Sealing those leaks is one of the most effective air quality fixes there is.
