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 HVAC Cleaning Across Nashua
HVAC cleaning in Nashua means opening up a 30-to-50-year-old forced-air system and dealing with what decades of Merrimack River valley humidity actually left inside. We clean the full system: evaporator coil, blower assembly, air handler, and the condenser outside, on raised ranches, split-levels, and capes across Nashua’s south and west-side subdivisions. If you’re noticing musty air when the furnace kicks on, dust blowing from registers, or a system that runs longer than it should, call CleanRun Air Duct Cleaning at (806) 606-6902. Every job gets a written price before any panel comes off, and a documented photo record of every duct run when we leave.
Why CleanRun Air Duct Cleaning Is Nashua’s Preferred HVAC Cleaning Company
We built our reputation in Nashua by showing homeowners what’s actually inside their systems before recommending anything. Not a sales pitch. A camera inspection on the first visit, with photos you keep. Tomas Reyes, who leads our crews, has spent years opening return grilles in Nashua’s west-side tract developments and finding the same thing: raw stud bays repurposed as return chases, packed with fiberglass fragments and construction debris from the original build. That’s not a talking point. It’s what the camera shows.
Our HVAC Cleaning crews work in Nashua weekly. Dispatch and scheduling run from our Boston metro office, but the technicians who show up at your door know Nashua’s housing stock: the 1970s-1980s raised ranches off Broad Street, the split-levels near Exit 5, the capes in the north end. That local knowledge changes how we diagnose a job. A 1980s tract home in southwest Nashua has different duct realities than a pre-WWII mill-worker house downtown. We plan around that before the first tool comes off the truck.
Every Nashua customer gets the same three things in writing: a price, a scope, and a 365-Day Done Right Promise. If the work isn’t right, we make it right. That’s Haven Standard Clause 7, and it’s printed on every job record, not just repeated on a website.
Our HVAC Cleaning Services in Nashua
Air Handler Cleaning
The air handler is the part most Nashua companies skip. It sits in the basement or a utility closet, pulling air across the coil and pushing it through the house. After decades of Nashua’s long heating season, the blower wheel caked with dust, the housing coated in fine particulate, and the drain pan holding moisture that feeds microbial growth. We remove the blower assembly, clean the housing, clear the condensate drain, and reassemble with the unit photographed before and after. In Nashua’s humidity, a skipped air handler means the first furnace cycle redistributes dust right back into the ducts you just paid to clean.
Evaporator Coil Cleaning
The evaporator coil sits above or beside the air handler, and in Nashua’s muggy summers it turns into a wet filter. Condensation collects, dust sticks to the fins, and within a few seasons you’ve got a mat of sludge insulating the coil and restricting airflow. We clean the coil with professional-grade equipment, not a garden sprayer. The coil treatment we apply afterward slows re-soiling and inhibits biological growth. If your coil hasn’t been cleaned in a decade, you’re paying to push air through a wall of grime every single cycle.
Blower Cleaning
Blower wheels in Nashua homes accumulate a fine gray paste: dust, pet dander, and humid air binding everything together. Once the blower wheel is loaded, it moves less air per rotation, which means longer runtimes, higher electric bills, and uneven temperatures room to room. We remove the wheel, clean each blade, and rebalance if needed. On a split-level off Broad Street last fall, the blower on a 1987 system was so loaded it was drawing 2.3 amps over spec. Cleaning brought it back within manufacturer range. That’s a real energy cost, not a hypothetical.
Condenser Cleaning
The condenser outside takes a beating in Nashua. Cottonwood fluff from the river corridor, maple keys, grass clippings, and winter road salt all work into the fins. A dirty condenser drives up head pressure, which shortens compressor life and makes every cooling dollar less efficient. We clean the coil fins, clear the interior, and check the clearance around the unit. If the fins are crushed flat from years of hail and the weed whacker, we’ll tell you straight and show you the photo.
Coil Treatment
After cleaning, we apply a coil treatment that slows re-soiling and inhibits biological regrowth on the evaporator. In Nashua’s Merrimack River valley humidity, that matters. A clean coil with no treatment re-fouls faster than most homeowners expect. This is a maintenance step, not a substitute for cleaning. We document the application in the photo record.

BeforeAfterTrusted Brands We Service in Nashua
Nashua homes run on everything from original 1970s oil-fired furnace retrofits to modern high-efficiency heat pumps. Our crews work on all of them, and we use equipment from brands you can look up independently: Rotobrush for source-removal agitation and negative-pressure collection, Nikro for HEPA-filtered air scrubbing, and Guardsman for coil cleaning and treatment applications. We don’t use shop-vacs and we don’t cut corners on filtration because the dust we pull out of a Nashua duct system doesn’t belong back in your living room. When a blower motor or coil component needs replacement, we source factory-matched parts and have them on the truck before the job starts.
Common HVAC Cleaning Problems We See in Nashua Homes
- Fiberglass in return-air chases. Many 1970s-1980s tract homes on Nashua’s west side used framed stud bays as return chases instead of sheet-metal ductwork. Open the grille and you’ll often find raw wood, fiberglass insulation fragments, and construction debris from the original build. Standard rotating brush equipment cannot reach into raw framing cavities, which is why so many Nashua homeowners have paid for duct cleaning and still smell must. The debris is still there.
- Microbial growth in duct liner from valley humidity. Nashua sits in the Merrimack River valley where summer humidity and seasonal fog push moisture into duct systems, particularly where AC condensate drainage is marginal. That moisture feeds biological growth in the interior duct liner. This is not a surface issue: fogging a sanitizer onto the liner masks it for a few weeks but never removes the source. The liner has to be cleaned to the substrate or replaced.
- Partially cleaned systems. We routinely see evidence of previous “cleanings” in Nashua where the crew cleaned the supply ducts but never touched the air handler or blower motor. The first heating cycle after the visit redistributed the accumulated dust right back into the supply and return. Cleaning only half the system is not cleaning. It’s a partial invoice with a full price.
- Deteriorating duct board in original forced-air systems. Nashua’s 1970s-1990s housing boom left thousands of homes with original duct-board plenums and supply runs. After 40 years, the fiberglass lining breaks down, releasing fibers into the airstream and holding moisture that supports biological growth. We document this on camera during the inspection so you can see the condition before deciding on a repair or replacement path.
Pricing for HVAC Cleaning in Nashua, NH
A full HVAC cleaning in Nashua, including air handler, blower wheel, evaporator coil, and the supply and return ducts, typically runs $895-$1,450 depending on system size and access. A partial service (air handler and coil only, for example) starts around $425. Homes with stud-bay return chases that require remediation-level source removal fall on the upper end because the work is more involved: negative pressure, agitation, and HEPA filtration, not a rotating brush pass. We give every Nashua homeowner a written price before any work begins, Haven Standard Clause 1. No per-vent pricing, no coupon that turns into an invoice three times larger. The price on paper is the price you pay. Call (806) 606-6902 for an exact quote on your system.

FAQs - HVAC Cleaning in Nashua
Builders in that era used framed stud-bay cavities as return-air chases instead of running sheet-metal ductwork, a cost-cutting practice that left raw wood and fiberglass insulation exposed to the airstream. Over decades, the insulation breaks down and fragments get pulled into the system. Standard brush cleaning cannot reach into these cavities, which is why a camera inspection is the only way to confirm whether a previous “cleaning” actually addressed the debris. Call (806) 606-6902 and we’ll show you the inside of your return chase before we touch a tool.
Yes. Nashua sits in the Merrimack River valley where localized fog and humidity hold moisture in the air longer than Manchester’s higher, less sheltered terrain, and that moisture finds its way into marginal AC condensate drainage and then into duct liner. The growth is inside the liner itself, which is why fogging sanitizers don’t solve it. Source removal or liner replacement does. We document what’s there on camera so the decision is based on evidence, not a sales script.
No. A fogging sanitizer coats the surface of the duct liner but cannot penetrate or remove biological growth that has colonized the liner itself. The spores and hyphae remain embedded in the material and regrow once humidity returns. Source removal means physically removing the contaminated liner or cleaning it to the substrate with HEPA-filtered negative-pressure extraction. We follow the NADCA standard for source removal on every Nashua job where microbial growth is confirmed.
Every 2-3 years for the evaporator coil and blower wheel if the system runs a full Nashua heating season plus summer cooling. Homes with pets, smokers, or renovation history should go more often. If you’ve never had it done on a house built in the 1980s, assume it needs it now. The coil on a 40-year-old system isn’t a maintenance item; it’s a restriction. We clean it, document it, and show you the before and after photos.
The NADCA standard (from the National Air Duct Cleaners Association) requires that cleaning remove the debris and contaminants from the duct system itself, not just dislodge them or coat them with a chemical. That means negative-pressure containment, agitation tools that reach the duct walls, and HEPA-filtered exhaust so nothing escapes into the home. The stud-bay return chases common in Nashua’s west-side subdivisions fall under this standard when the debris requires agitation and removal beyond a standard brush pass. We align every Nashua job with NADCA source-removal practice and document the process in the photo record.
