Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Repair Across Pleasant Hill
Air duct repair in Pleasant Hill usually means one of three things: sealing leaks in aging attic ductwork, reconnecting joints that have pulled apart, or replacing crushed or deteriorated sections. Most jobs in this area run between $350 and $900, depending on how much of the system needs work. Our crews know the exact failure patterns in Pleasant Hill’s 1960s and 70s ranch homes because we see them every week. Call (980) 447-2498 for a written estimate before any work begins.
Why Linden Air Duct Cleaning Is Pleasant Hill’s Preferred Air Duct Repair Company
We’ve been repairing duct systems in the Diablo Valley long enough to know what the original builders left behind. Homeowners off Contra Costa Boulevard, Golf Club Road, and up into the Reliez Valley foothills call us when rooms won’t heat evenly or when a smoke smell returns every fall. The work we do holds up because we fix the actual problem: failed seals, disconnected flex joints, crushed runs. Not a fogging treatment that masks the symptom for a month.
Every technician who comes to a Pleasant Hill home is background-checked, identity-verified, and photo-badged under the Threshold Standard. You get the tech’s name and photo before the visit. At the door, they show a photo ID badge. Marcus Veale leads our team, and the standing rule is simple: written price before work starts, written guarantee on every repair, and a free second visit if the repair fails within 365 days.

Ductwork Installation in Pleasant Hill
Ductwork Installation in Pleasant Hill typically means replacing sections of original sheet-metal duct that have corroded, collapsed, or been so thoroughly compromised by 50-plus years of Diablo Valley temperature swings that sealing alone won’t fix them. A partial replacement in a ranch home here commonly runs $800 to $1,600, while a full system replacement can reach $3,000 to $6,000 depending on the home’s layout and the run length through the attic. We’ll quote the exact figure in writing before any material gets ordered.
Attic Run Replacement
In a split-level off Oak Park Boulevard, the supply trunk running through an unconditioned attic has spent decades baking at 130°F in summer and chilling near freezing on winter nights. Sheet metal fatigues. Joints separate. When we replace these runs, we use sealed flex connectors and mastic at every joint, sized to the blower’s static pressure. That’s the difference between a repair that lasts and one that fails again in two years.
Supply and Return Trunk Rebuilds
The return side matters just as much as the supply. A crushed return trunk starves the blower, drives up utility bills, and pulls attic air into the system. We rebuild return trunks with the same sealed-connection standard we use on supply lines. In Pleasant Hill ranch homes, this work usually runs $900 to $2,200.
HVAC Duct Installation in Pleasant Hill
HVAC Duct Installation in Pleasant Hill goes beyond replacing old sections; it’s the full installation of new duct runs when the existing system can’t be economically repaired. Homeowners choose this path when ductwork has collapsed entirely, when renovation changes the home’s layout, or when fiberglass duct liner has absorbed so much wildfire smoke that odor keeps returning. Expect $3,500 to $7,000 for a complete system in a typical 1,400 to 1,800-square-foot ranch.
New Flex Duct Runs
Replacing old rigid runs with new insulated flex duct is common in Pleasant Hill’s low-clearance attics. Flex duct follows the existing chase, seals tight at every connection, and carries an R-value that the original un-insulated sheet metal never had. This work is done under negative pressure with HEPA filtration running, so attic dust and insulation particles don’t get pushed into your living space.
Whole-System Duct Replacement
When a furnace or AC replacement is happening anyway, it’s often the right moment for whole-system duct replacement. We coordinate with your HVAC contractor, or handle the duct side entirely. You get a written price, a written guarantee, and a system that holds static pressure on day one and five years later.
Trusted Brands We Service in Pleasant Hill
We work on duct systems connected to all major furnace and air handler brands in Pleasant Hill homes, including Carrier, Trane, Lennox, Rheem, and Goodman. That matters when a repair has to match an existing plenum or fan-coil connection. We keep common fittings in our Bay Area dispatch, so most Pleasant Hill jobs don’t wait on parts. Where air quality improvements are part of the repair, we install products from Aprilaire, Abatement Technologies, and Guardsman. Our extraction and agitation equipment comes from Rotobrush and Nikro.
Common Air Duct Repair Problems We See in Pleasant Hill Homes
- Failed foil-tape seals. Original tape on 1960s and 70s attic ductwork dries out and peels back. Once that seal fails, the supply side pulls attic air (insulation dust, smoke particles, whatever’s up there) straight into your rooms.
- Disconnected flex joints. Split-level layouts require long flex runs through tight attic spaces. Over decades, connectors slip or get knocked loose, and airflow drops hard. That’s why one bedroom is freezing while the living room is fine.
- Smoke-absorbing fiberglass liner. Pre-1980 ducts often have fiberglass interior lining. After Diablo wind events push wildfire smoke through the valley, that liner holds the odor and re-releases it every time the heat cycles on.
- Crushed attic runs. Storage boxes, holiday decorations, a careless contractor. We find crushed duct runs in nearly every older Pleasant Hill home we open up. The fix is replacement, not duct tape.

FAQs About Air Duct Repair in Pleasant Hill
Pleasant Hill’s inland Diablo Valley position means summer temperatures routinely hit 95 – 100°F, so AC runs hard for months. That accelerates debris accumulation and thermal stress on 45 – 65-year-old attic ductwork. Add fall Diablo wind events pushing wildfire smoke through the valley, and these systems take a beating that coastal homes 15 miles west simply don’t experience at the same intensity. Call (980) 447-2498 for a system assessment.
Only if the cleaning includes source removal with agitation and HEPA filtration, not just vacuuming. Fiberglass duct liner in pre-1980 ranch homes absorbs smoke odor and re-releases it on every heating cycle. On a 1968 ranch off Golf Club Road, our tech found exactly this after the 2020 fire season. A camera inspection showed a disconnected flex joint and failed foil-tape seal near the air handler. We resealed both with mastic under negative pressure, then performed source removal with agitation tools and HEPA filtration. The smoke smell on startup was gone. A cheap fogging treatment won’t do that.
You’ll see the signs: rooms that never reach the thermostat setting, dust appearing on surfaces within days of cleaning, and utility bills higher than they should be for the square footage. A blower-door duct test or a camera inspection confirms the leak’s location. We camera every repair we quote. Leaks this old don’t heal, and the blower overtime cost adds up faster than the repair.
Yes. When summer highs sit in the high 90s, a leaking duct system wastes cooled air into the attic. The AC runs longer, the blower works harder, and the system degrades faster. What’s a comfort issue in spring becomes a real utility bill problem by July. Repairing leaks before the heat peaks is the cheapest time to do it. Our written quotes hold for 30 days.
Sealing. Not fogging. A real repair finds the physical failure (failed seal, disconnected joint, crushed run) and fixes it with mastic, new flex connectors, or replacement duct sections. A fogging sanitizer sprays a chemical into the duct that masks odor but does nothing for airflow or leakage. In Pleasant Hill’s aging attic systems, that’s a month of nice smell followed by the same problems. Our repair includes source removal, physical sealing, and a written 365-day guarantee. Call (980) 447-2498 for an honest quote.
