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 Cleaning Across Delaware
Air duct cleaning in Delaware, OH typically runs $350 – $650 for a standard whole-home system, and the work itself takes about 3 – 5 hours. We serve every neighborhood in Delaware, from the historic streets near the Delaware County Courthouse to the newer developments along the US-23 corridor. Call (737) 727-2314 for a written quote before any work begins. You’ll get one flat price per system, not a per-vent quote that shifts once the van is in your driveway.
Why Cardinal Air Duct Cleaning Is Delaware’s Preferred Air Duct Cleaning Company
Delaware homeowners call us because we answer the phone, show up when we say we will, and hand over a written price before a single duct is touched. The Relay Standard booking experience means you get a live trackable arrival window, a technician whose name and background you know before the door opens, and before-and-after photo documentation of your own ducts. No voicemail loops. No four-hour windows. No mystery invoice at the end.
Our techs work on Delaware’s mix of housing every week. That matters because cleaning ducts in a 1920s two-story near Ohio Wesleyan University is not the same job as cleaning a 2018 build off Glenn Parkway. Older flex and galvanized runs behave differently under agitation than newer sheet metal. We know what to look for in each. Omar Haddad leads our crews with a simple rule: if the work isn’t right within 365 days, we come back and correct it at no charge. That’s the 365-Day Done Right Promise, and it applies to every booking without exception.
Air Duct Inspection in Delaware
Air Duct Inspection in Delaware is a video camera walkthrough of your supply and return runs before any cleaning starts. It costs $95 – $150 as a standalone service in Delaware and is waived when you book a full cleaning. We run the camera through your trunk line and every accessible branch, and you see the footage on the spot.
When Inspection Catches What Cleaning Would Miss
In Delaware’s older housing stock, inspection frequently turns up disconnected flex runs, crushed sections, or gaps where the return plenum meets the trunk line. Cleaning those systems without looking first pushes dust around but never fixes the path it travels. Our techs map what they find, show you the footage, and quote any repair as a separate line item you approve before we touch it.
What You Actually Get
You get digital before-and-after captures of the same duct sections, not stock photos. If we find a collapsed run, we show you the screen. If we find mold-like growth, we tell you what it is and where, and recommend testing if you want it. The camera doesn’t lie, and neither do we.
Residential Air Duct Cleaning in Delaware
Residential Air Duct Cleaning in Delaware is source removal under negative pressure: we agitate the debris bonded to duct walls, then extract it directly into a Nikro HEPA-filtered vacuum so nothing recirculates into your living room. A standard single-system home in Delaware runs $350 – $650. We’ve cleaned ranch homes off West William Street, colonials near Mingo Park, and new builds in the Terra Alta subdivision off US-36.
The Process in Plain Terms
We seal off each register one at a time, connect a high-powered vacuum to the trunk line, and feed Rotobrush agitation tools through every run under NADCA standards. The agitation breaks loose the fiber, lint, and dust caked onto the walls; the negative pressure pulls it straight into the HEPA unit outside or in the truck. What we don’t do is run a shop-vac hose in one vent and call it done.
One Flat Price, Not Per-Vent Math
Duct cleaning in Delaware gets quoted two ways: per vent or per system. Per-vent rewards a quick pass over ten grilles and punishes anyone with a small house having many runs. We quote one flat price per system, agreed in writing before work starts, and it does not change at the door. That’s the only way a price means anything.
Trusted Brands We Service in Delaware
We service and work around the filtration and HVAC equipment already installed in Delaware homes: Honeywell media cabinets, Aprilaire whole-home units, and Guardsman air cleaners. When your Aprilaire filter housing sits downstream in the return and the duct cleaning must not disturb its seal, our techs remove and reinstall it properly instead of taping around it. We stock common replacement filters and access panels for these brands on the truck, so a Delaware job rarely needs a second visit for parts. That keeps turnaround tight and the invoice predictable.
Common Air Duct Cleaning Problems We See in Delaware Homes
- Collapsed flex runs in supply and return branches. Delaware homes from the 1950s through 1980s often have original flex ducting that sags, kinks, or tears behind drywall. We find it during camera inspection, and we show you the footage before recommending repair or replacement.
- Return-side leakage in older downtown homes. Houses near the Courthouse commonly pull unconditioned attic or basement air through gaps in the return plenum. That means dust keeps coming back even after a thorough cleaning, because the system is drawing it in from outside the envelope.
- Dryer lint migration into adjacent ducts. In tight mechanical rooms around Ashley and Troy Roads, we often see dryer exhaust sharing a chase with the supply trunk. A loose dryer vent connection pushes lint straight into the supply stream, and you breathe it.
- Construction dust from the US-23 growth corridors. Newer builds off Glenn Parkway and Sawmill Parkway settlement dust lingers in ducting for months after move-in. The drywall and trim dust doesn’t settle on surfaces only; it packs into trunks and branches and circulates every time the blower runs.
Pricing for Air Duct Cleaning in Delaware, OH
Most standard whole-home air duct cleanings in Delaware run $350 – $650, depending on home size, number of systems, and condition of the existing ductwork. A 1,200-square-foot single-story home typically lands at the lower end; a 2,800-square-foot two-story with two air handlers sits at the upper end. Video inspection adds $95 – $150 if booked alone and is waived with full cleaning. If you have an Aprilaire or Honeywell unit, there is no extra charge to service around it; we remove and reinstall the filter housing as part of the job. Written price first, always.

FAQs About Air Duct Cleaning in Delaware
Every 3 – 5 years for most Delaware homes. You can stretch that longer if you have no shedding pets, run a good media filter, and changed the filter on schedule. You should shorten it to every 2 – 3 years if you have multiple pets, smoke indoors, or just finished a renovation near the US-23 corridor. If you bought an older Delaware home and the previous owners had carpet installed over original ducts, get it cleaned once at move-in and then decide based on what the camera shows. Call (737) 727-2314 and we’ll tell you honestly if you can wait.
Per system, always. One flat price for your entire duct network, written down before any work starts, and it doesn’t change at the door. Per-vent pricing is how Delaware homeowners get quoted low and billed high. We don’t play that.
Yes. Every job includes before-and-after photographs of your own trunk line, branches, and the debris collected. You see the same sections of your own ducting, not a stock image. If we find a collapsed flex run off West William Street like we did on a 1960s ranch recently, you’ll see the camera footage of that too.
Yes. If your Aprilaire media cabinet or Honeywell electronic air cleaner sits inline with the duct system, we remove the filter housing, clean around it properly, and reinstall it as part of the same job. There is no separate equipment fee. You don’t need a second HVAC contractor for that portion.
We don’t book same-day duct cleaning, and you should be wary of anyone who does. A proper cleaning requires sealing registers, running full-length agitation through every branch, and maintaining negative pressure for hours. Rushing that means debris left in the trunk line and no proof it was ever removed. We schedule within a normal window, confirm the price in writing before the crew leaves the shop, and show you the work when it is done.
You know your Delaware home better than any contractor. We just bring the camera, the HEPA vacuum, and the flat price. Call (737) 727-2314 for a free estimate, or book online and get your written quote before we arrive.
