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 Derry
Air duct cleaning in Derry for a typical single-family colonial or ranch runs $450-$900 for a full system clean, depending on the number of furnace runs, whether flex duct needs support repair, and how much debris has accumulated since the last service. That price includes a written quote before any panel comes off, a camera inspection of the interior, and a before-and-after photo record of every duct run we touch. If you’re in Derry and want to know what’s actually inside your ductwork, call (806) 606-6902 and we’ll start with the camera, not a sales pitch.
Derry’s housing stock has a specific profile: rapid buildout through the 1970s, 80s, and 90s along the Route 28 corridor, thousands of colonials and ranches, and a heating season that runs six-plus months. That means forced-air systems here cycle constantly, pull construction dust and pet dander through the returns, and rarely get the maintenance they need. We know the subdivisions off Tsienneto Road, the older stock near East Derry village, and the new builds around Adams Pond Road. Our crews serve Derry directly, with dispatch coordinated from the brand’s Boston office.
Why CleanRun Air Duct Cleaning Is Derry’s Preferred Air Duct Cleaning Company
We don’t ask Derry homeowners to trust us on faith. Every Air Duct Cleaning job starts with a camera inspection and a written price, so you see the debris before you spend a dollar. Tomas Reyes, who runs CleanRun, has built the company since 2013 on one principle: show the customer what’s in the duct, put the price in writing, and photograph the result. That’s why we carry a 365-Day Done Right Promise, written into every job record, not just printed on a brochure. If it’s not done right, we make it right.
Beyond the written guarantee, our techs are background-checked, uniformed, and identified by name before arrival, per Haven Standard Clause 3. The equipment we run includes Rotobrush agitation systems, Nikro negative-air machines, and Abatement Technologies HEPA filtration. That equipment is professional-grade and you can look up each brand independently to verify what we’re using before we arrive. Derry homeowners who’ve already dealt with the $79-coupon bait-and-switch that plagues this industry tend to notice the difference quickly.
Our Air Duct Cleaning Services in Derry
Residential Duct Cleaning
Most Derry homes we service are colonials and ranches built between 1975 and 1995, with sheet-metal trunks and either insulated flex or rigid branch runs. We source-remove debris from the supply and return sides, the plenum (the box where ducts meet the air handler), the blower motor housing, and every register. In Derry’s older homes near East Derry village, we often find retrofitted systems with ducts running through tight crawl spaces that were never designed for regular access. We clean those too, and we photograph the inside before and after so you can see the difference.
Commercial Duct Cleaning
Derry has small commercial buildings scattered along Route 28 and the industrial pockets near the Manchester line. These systems collect restaurant grease, office dust, and years of deferred maintenance. Our commercial crews work after hours when needed and deliver the same documented photo record we give to residential customers. If you manage a commercial property in Derry, ask to see what’s in your ducts before you sign anything.
Supply Duct Cleaning
Supply ducts in a Derry colonial are the arteries that push conditioned air into the rooms. When they’re coated with dust, the system works harder and blows fine particles into the living space. In new construction around Adams Pond Road, we regularly find drywall dust and sawdust coating supply runs before the family has even moved in. We clean the supply side thoroughly, including the boots and registers, and photograph every run.
Return Duct Cleaning
Return ducts are the neglected half of most systems. They pull air back to the air handler, and if the filter was ever run clogged or the returns were left open during renovation, they carry that debris straight through the system. Builders in Derry sometimes leave return registers open during drywall sanding, which pulls fine gypsum dust into the air handler and slowly grinds down the blower motor. We clean return ducts as carefully as supplies and check the filter housing while we’re there.

BeforeAfterTrusted Brands We Service in Derry
We work on systems built around Honeywell and Aprilaire components, and we keep common replacement parts stocked for quick turnaround on Derry jobs. When a job calls for source-removal extraction, our crews use Rotobrush agitation tools paired with HEPA-filtered negative pressure, which is the same method used in commercial remediation work. If your Derry home has an Aprilaire filter housing or a Honeywell thermostat and zone controller, our techs know how to clean around the install correctly and verify everything is seated back properly when we’re done.
Common Air Duct Cleaning Problems We See in Derry Homes
- New construction dust: In the recent builds around Adams Pond Road and other Derry subdivisions, we find drywall dust and sawdust coating the supply and return ducts at handover. It bakes onto the coils and blower motor during the first heating season and reduces airflow noticeably.
- Sagging flex duct in 1980s attics: Off Tsienneto Road and around Crystal Lake, many homes have flex duct laid across attic floors with minimal support. The duct sags, traps debris and condensation, and in Derry’s freeze-thaw cycles, that moisture promotes mold growth inside the liner.
- Oil-to-gas conversion residue: Many Derry homes built in the 1970s and 80s were originally heated with oil-fired forced air, then converted to natural gas. The original ductwork was rarely cleaned during conversion, leaving decades of oil-combustion soot baked into the system.
- Debris in returns after renovation: When homeowners renovate or builders finish a basement, they often leave return registers open. Fine gypsum and sawdust get pulled into the air handler and wear down the blower motor bearings long before their time.

FAQs - Air Duct Cleaning in Derry
Builders in Derry rarely clean ductwork after construction, even when the build was a full custom job. Drywall sanding produces fine gypsum dust that settles into supply ducts and the air handler, while sawdust from trim work ends up in the returns. If not cleaned before the first heating season, that debris bakes onto the coil and blower motor, reduces airflow, and shortens system life. We recommend a full system clean with video inspection before move-in. Call (806) 606-6902 for a written price.
Yes, and most builders don’t. It’s not a code requirement in Derry, so it gets skipped. The builder’s job is framing, drywall, and finishes; duct cleaning is a separate trade that almost never makes it into the contract. We regularly clean new construction homes around Adams Pond Road and find the same thing: drywall dust and sawdust coating every run. Documenting this with our camera inspection is part of the job record we hand to the homeowner.
Yes. Flex duct laid across attic floors in 1980s Derry homes off Tsienneto Road and around Crystal Lake often sags under its own weight, trapping debris and condensation. Derry’s freeze-thaw cycles worsen this because warm air from the conditioned space condenses inside the cold attic duct, then freezes and thaws repeatedly. That moisture promotes mold inside the liner. We inspect the support straps and replace or re-hang sagging runs as part of the cleaning job when needed.
We source-remove debris from every supply run, boot, and register using Rotobrush agitation tools with HEPA-filtered negative pressure. That means we’re pulling the debris out of the system, not just loosening it and pushing it around. In Derry colonials, the supply plenum above the air handler often holds years of settled dust that never makes it to the registers, so we clean that too. Every run is photographed before and after and included in your job record.
The short answer: run a camera. Returns are where renovation debris gets pulled into the system, and in Derry homes that have had basement finishes, kitchen remodels, or drywall patches, fine dust often coats the return side unseen. If you see a dusty film on the wall near return registers, or if your filter loads faster than it should after a renovation, that’s a signal. We include video inspection before and after every clean, so you see exactly what we found. Call (806) 606-6902 and we’ll start with the camera.
