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 Merrimack
Air duct cleaning in Merrimack typically runs $420-$780 for a full system on a 1,800-2,400 sq ft colonial, and most jobs are completed in a single visit. If you’re in a 1970s-era home off Daniel Webster Highway or a condo near the Souhegan River, your ductwork has been moving air for four or five decades, and the question isn’t whether it needs cleaning. It’s what the camera will show once we open the first access panel. CleanRun has worked Merrimack’s housing stock long enough to know the answer before we start. Call (806) 606-6902 for a written price before a single panel comes off.
Why CleanRun Air Duct Cleaning Is Merrimack’s Preferred Air Duct Cleaning Company
Merrimack homeowners ask for two things: a price in writing and proof the work happened. We do both on every job. Tomas Reyes set the standard in 2013 when he started CleanRun with a rule that still holds: no work begins without Haven Standard Clause 1, a written price for the entire scope. That’s not a marketing line. It’s the document you sign before our crew opens the first register. And when we finish, you get a Documented Photo Record of every duct run, inside before and after. Not a summary. The photos.
We’re independently owned and operated under the Haven Standard, and our background-checked, uniformed technicians arrive with Rotobrush and Nikro equipment you can look up yourself. We don’t ask you to take our word on anything. We hand you the evidence. That approach is why Merrimack customers keep our number, and why our 365-Day Done Right Promise sits in writing on your invoice rather than on a brochure.
Our Air Duct Cleaning Services in Merrimack
Residential Duct Cleaning
Single-family homes on Merrimack’s winding side streets off Continental Boulevard and Baboosic Lake Road need more than a surface vacuum. Our residential crews perform negative-pressure extraction through the full duct run, from return registers to supply plenum, and camera-verify every section before closing. For a 1970s split-level off Back River Road, that means documenting whether the original sheet metal has separated at the seams, which changes the scope and the price. You’ll see it in the written quote before work starts.
Commercial Duct Cleaning
Offices and retail spaces along the Daniel Webster Highway corridor cycle air continuously through rooftop units during southern New Hampshire’s long heating season. CleanRun handles commercial supply and return systems without shutting down your whole operation. We schedule access in sections, show the property manager what the camera found at each plenum, and deliver the same Documented Photo Record we give a homeowner. No different equipment. No different standard. Same written price first.
Supply Duct Cleaning
Supply ducts carry conditioned air from your furnace to every room. In Merrimack’s older colonials, those supply runs are often original 1970s sheet metal with accumulated debris at the register boots and first elbows. We clean supply runs under negative pressure with mechanical agitation, then photograph each register from the inside. If we find a disconnected or collapsed flex duct, which is common in Merrimack’s early construction, the photo goes in your job record and the repair gets quoted separately in writing.
Return Duct Cleaning
Return ducts are where we find the most problems in Merrimack, and it’s not even close. Homes along the Route 3 corridor often have return-air chases that run through garage-adjacent walls, pulling exhaust and fine particulates directly into the system. Cleaning the supply side while skipping the return side means you’re still breathing whatever the garage has to offer. Our Air Duct Cleaning process treats return runs as a distinct scope, with camera inspection before and after and written documentation of any compromised pathways we seal.

BeforeAfterTrusted Brands We Service in Merrimack
Merrimack homes run on equipment from a specific era, and we maintain familiarity with the Honeywell air cleaners and Aprilaire media cabinets that builders installed through the 1980s and 1990s. Our technicians service and integrate cleaning around those components rather than working around them. We use Guardsman, Rotobrush, and Nikro equipment on site, and our crews carry the filters, gaskets, and access fittings needed to reseal duct runs after cleaning without ordering parts and leaving your system open overnight. That’s standard operating procedure, not an upsell.
Common Air Duct Cleaning Problems We See in Merrimack Homes
- Garage-adjacent return air chases. In homes built along the Route 3 corridor in the 1970s and 1980s, return ducts often run through walls shared with attached garages. The camera regularly shows exhaust residue and fine particulate entering those returns. Sealing the chase is part of a correct cleaning job here, not an optional add-on.
- Collapsed or disconnected flex duct in early construction. Merrimack’s first wave of flex duct installations from the early 1980s has reached end of life. We find sections that have slipped off boots or collapsed under insulation weight, and a brush-and-vacuum-only approach would miss all of it.
- Musty odors from river-valley humidity. The Merrimack River creates a moisture corridor that pushes higher ambient humidity into ductwork seasonally. Those conditions accelerate dust-and-mold accumulation in the plenum and first few feet of the duct run, even when the rest of the system looks clean.
- Shared dryer vent stacks in condo complexes. Merrimack’s multi-unit buildings off Continental Boulevard and near the river often route dryer vents through common stacks. One unit’s restricted lint pathway creates backpressure for every unit on the line. We clean and camera-verify the entire shared run, and advise the association when we see a design problem that will keep coming back.
Pricing for Air Duct Cleaning in Merrimack, NH
A full system cleaning for a typical Merrimack single-family home runs $420-$780, depending on the number of duct runs, access difficulty, and whether you’re including return-duct sealing.

Video inspection is $95 when ordered as part of a cleaning and $150 as a standalone diagnostic. Commercial pricing ranges $0.18-$0.35 per square foot depending on system accessibility. Every quote is one flat price for the whole system, written before work starts under Haven Standard Clause 1. Bring a competitor’s written estimate and we’ll put our number next to it, free.

FAQs - Air Duct Cleaning in Merrimack
In Merrimack’s 1970s-era colonials, the smell usually comes from return ducts pulling air through garage-adjacent wall cavities or from moisture accumulation in the main return plenum caused by river-valley humidity. We camera-inspect the return pathway and show you the exact entry point and condition before recommending sealing or cleaning. Whether the fix is a full return-duct cleaning or a targeted pathway seal, you’ll see it in writing first. Call (806) 606-6902 to schedule a video inspection.
Yes, in Merrimack you need return ducts addressed separately. Supply-only cleaning leaves the return side of the loop exactly as it was, and in homes along the Route 3 corridor, the return side is usually the dirtier and more problematic half. Our return-duct scope includes camera inspection, mechanical agitation, negative-pressure extraction, and written documentation of any compromised pathways we seal. We’ll quote the two scopes separately so you see exactly what each costs.
Every 4 to 6 years. Homes closer to the Merrimack River and its tributaries experience higher ambient humidity that accelerates particulate buildup inside ductwork, especially in the return plenum and first sections of the run. If your system has never been cleaned and the home was built between 1970 and 1995, schedule a video inspection now rather than guessing. The camera either shows a problem or it doesn’t.
Yes. We work in Merrimack condo complexes regularly, and we isolate each unit’s duct system before applying negative pressure so we’re not pulling air through connected runs or disrupting a neighbor’s unit. If your building has a shared dryer vent stack, we’ll note whether the blockage is in your segment or the common line and give you written documentation to share with the association if needed.
We clean shared dryer vent stacks from the roof access point, camera-verify the entire run, and document where the lint buildup sits. If the restriction is in your unit’s branch, we clean that section and photograph the result. If the buildup is in the common riser, we provide the association with a written scope and photo evidence so the shared portion gets addressed. One clogged lint pathway in a stacked system affects every unit on the line, so we document it clearly enough for the board to act on.
