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.

AfterFast, Reliable Air Duct Cleaning Across Wilmington
Air duct cleaning in Wilmington, DE typically costs between $380 and $720 for a full system on a rowhouse, and most jobs take half a day. If you’re looking for Wilmington HVAC Cleaning, we bring the same documented approach to every job. That’s the honest range before any work starts, in writing, under Haven Standard Clause 1. We serve every Wilmington neighborhood, from the East Side to Trolley Square, with crews who know what’s actually inside these older systems. Call (806) 606-6902 for an exact written price.
Why CleanRun Air Duct Cleaning Is Wilmington’s Preferred Air Duct Cleaning Company
Wilmington’s housing stock doesn’t fit a franchise playbook. The pre-WWII brick rowhouses concentrated on the East Side, West Side, and Forty Acres were built for coal heat, then retrofitted with forced-air ductwork in the 1950s through 70s. Those ducts were shoehorned into basements and chases never designed for them. We’ve seen enough of these systems to know that a 30-foot duct run in a Wilmington rowhouse can have four elbow turns, two diameter changes, and a low-clearance basement plenum that most crews won’t even bother to open.
Our Air Duct Cleaning team includes technicians who have worked hundreds of rowhouse systems in this city. We don’t send a crew that’s never seen a 1920s galley basement or a galvanized return drop corroded by river humidity. Every job ends with a Documented Photo Record: inside every run, before and after, delivered to you as part of the standard job record. Since 2013, Tomas Reyes has built CleanRun on the idea that you should see what was actually done, not take a technician’s word for it.
Wilmington homeowners call us because we name the price in writing before a single panel comes off, and we photograph the inside of the ductwork before and after. No verbal estimates. No “we’ll see what we find.” Just a documented record you can keep, show your insurer, or compare against a competitor’s quote.
Our Air Duct Cleaning Services in Wilmington
Residential Duct Cleaning
A full residential system in a Wilmington rowhouse includes the supply and return sides, the plenum, and every reachable register. Older retrofitted systems here often have debris packed into irregular runs that a standard vacuum-only pass won’t touch. We use negative-pressure extraction with source removal contact, meaning the Rotobrush or Nikro agitation head physically contacts the duct walls instead of just stirring air around. The before and after photos show the difference.
Commercial Duct Cleaning
Wilmington’s commercial buildings along Market Street, the Riverfront, and the office corridors near Rodney Square carry higher occupant density and longer runtime hours than residential systems. That means more skin cells, more carpet fiber, and more recirculated particulate. We schedule commercial work around your operating hours and document every run we clean. The photo record gives building managers something concrete to file for tenant inquiries or health department questions.
Supply Duct Cleaning
Supply ducts move conditioned air into your rooms. In Wilmington rowhouses, these runs are frequently the ones that were retrofitted in the 1950s and 60s, meaning galvanized steel or flex duct crammed through low-clearance basement spaces. Dust, pet hair, and construction debris from decades of renovations pack into these runs, especially at the first elbow after the plenum. The camera inspection we run first shows you exactly what’s sitting in there before we touch anything.
Return Duct Cleaning
Return ducts pull air back to the furnace. In Wilmington, return drops in older homes are often oversized or undersized for the forced-air systems retrofitted into them, which creates uneven airflow and lets debris settle in low spots. Corrosion inside galvanized return drops is common near the river, especially in Riverside and South Wilmington where groundwater proximity keeps basement humidity high. We document that corrosion on camera, because it determines whether cleaning is enough or whether a section should be replaced and sealed.

BeforeAfterTrusted Brands We Service in Wilmington
We run professional-grade equipment from brands you can look up independently: Rotobrush, Nikro, Honeywell, and Guardsman. We don’t own a shop-vac with a hose attachment. For Wilmington’s older systems, we stock replacement flex duct, mastic sealant, and galvanized fittings locally so a repair found during cleaning doesn’t stall the job. If your system uses Honeywell air cleaners or Guardsman-rated components, we’re familiar with the install patterns and can work around them without damaging the equipment.
Common Air Duct Cleaning Problems We See in Wilmington Homes
These aren’t hypothetical. These are what we actually find when the camera goes in:
- Mildew-smelling basement plenums without visible flood lines. Wilmington’s uninsulated slab and dirt-floor basements, combined with the humidity off the Christina River, create chronic moisture inside original galvanized plenums. The smell is there long before any standing water.
- Debris packed into retrofitted runs that positive-pressure blowing can’t remove. A blower-only pass won’t break loose years of compacted dust in a 1950s retrofit with four elbows. Source removal contact is the only thing that works.
- Corroded galvanized return drops after Brandywine flood events. Once the metal rusts through or the seams separate, cleaning won’t fix it. That’s a replacement, and we document it with photos your Delaware insurer can accept.
- Disconnected or poorly seated flex duct in low-clearance basements. The original retrofits in Wilmington rowhouses often used flex duct that’s since pulled loose at the collars, pulling basement air into the system. We find and seal those during the cleaning.

FAQs - Air Duct Cleaning in Wilmington
The answer depends on whether the duct material is still structurally sound. If the galvanized metal is intact but has mud or debris inside, cleaning with HEPA filtration and antimicrobial treatment is usually sufficient. If the metal is rusted through, the seams have separated, or the flex duct was waterlogged and collapsed, no amount of cleaning restores it. We run a camera inspection before we recommend anything, and we document what we find. If replacement is warranted, that photo record is what your Delaware insurer needs to process the claim. Call (806) 606-6902 and we’ll put the camera in before any cleaning decision is made.
Because Wilmington’s older basements hold moisture year-round. Forty Acres homes sit on uninsulated slab or dirt floors, and the humidity off the Brandywine and Christina keeps the air damp. The original galvanized plenum metal sweats, gathers condensation, and eventually develops surface mold and that characteristic mildew odor. It doesn’t take a flood. We address this with source removal inside the plenum, HEPA filtration during the cleaning, and sealing the plenum seams to stop recontamination. Call (806) 606-6902 for a written price on the full service.
We photograph every duct run before and after, with a camera that shows the interior condition, the corrosion or waterline inside the metal, and the specific section that’s failed. We include a written scope that states what was found, what was cleaned, and what was replaced, with corresponding photos. That’s the documentation insurance adjusters accept because it shows the condition, not just a claim about it. Our Documented Photo Record is a standard deliverable on every job, not an add-on you have to request. Call (806) 606-6902 for an inspection.
Yes. We’ve worked in East Side basements where the duct runs through spaces under 30 inches of clearance. The job takes longer and costs a bit more because access is difficult, but the equipment we use, including Rotobrush and Nikro agitation heads, is designed for tight access. We’ll show you the before and after photos so you know the run was actually reached, not skipped because it was inconvenient. Call (806) 606-6902 and we’ll give you a written price that accounts for the access difficulty up front.
It reduces the dust that’s already collected inside the ductwork from being recirculated into your rooms. Trolley Square Victorians have oversized, multi-story duct chases from 1920s and 30s conversions, and those big runs hold more dust than a modern build. If the system has leaks pulling attic or basement air into the return side, some dust will still come in until those gaps are sealed. We identify those during the cleaning and seal what we can reach. The photo record shows you what was there before and what’s left after. Call (806) 606-6902 for a written price.
