Fast, Reliable Air Duct Cleaning Across Exeter
Air duct cleaning in Exeter, NH typically runs $350–$650 for a full residential system and $800–$1,400 for commercial properties, with most jobs completed in a single visit. We’re Titan Air Duct Cleaning Lowell, and we make the drive up Route 125 to Exeter regularly — usually same-day or next-day when you call (877) 517-5646. Thomas Hernandez, our owner and lead technician, has been cleaning air duct and HVAC systems for 14 years, and he’s personally on every Exeter job we book.
Exeter isn’t like the inland New Hampshire towns we serve. The Squamscott River runs right through the historic core, and that tidal estuary moisture changes everything about what we find inside ductwork here. Our Air Duct Cleaning team knows the difference between a routine debris removal job and the mold-remediation-level clean that Exeter’s older homes often need. We’ve worked on Water Street colonials, downtown Federal-style homes near the Phillips Exeter Academy campus, and mid-century ranches out toward Kensington Road — each with its own duct configuration and its own moisture profile.
Why Titan Air Duct Cleaning Lowell Is Exeter’s Preferred Air Duct Cleaning Company
We’ve earned 389 verified reviews averaging 4.7 stars, and a growing share of them come from Exeter homeowners who found us after a bad experience with a low-bid franchise crew. They tell us the same thing: the other company showed up with a shop vac and a brush, spent 45 minutes, and left the mold still growing in their basement supply run. Thomas shows up — as the owner and the technician doing the work — with Rotobrush, Nikro, and Abatement Technologies equipment built for more than a basic residential clean.
Our response time to Exeter is typically same-day or next-day, depending on whether we’re already on a job in Kingston or Seabrook. We know the local roads, the parking situation around the historic district, and the access challenges of working in 200-year-old cellars with stone staircases and low ceilings. That local knowledge saves time and prevents damage.
Exeter customers also get the benefit of our full duct-system scope. We don’t just clean — we repair, seal, and sanitize. In a town where so many ducts were retrofitted into spaces never designed for them, that matters. A cleaning crew that can’t spot a detached connection or a failing seal is a crew that’s leaving the real problem behind.
Our Air Duct Cleaning Services in Exeter
Residential Duct Cleaning
Exeter’s housing stock demands more than a standard residential protocol. In the historic district, we regularly encounter supply and return ducts routed through damp stone cellars, sometimes with original 1950s sheet metal that’s never been properly sealed. Our residential cleaning includes full HEPA-contained debris removal, followed by inspection for the moisture damage and microbial growth that the Squamscott River microclimate promotes. We treat these older systems with the care they require — no aggressive brushes that could detach fragile retrofit connections.
Commercial Duct Cleaning
Exeter’s commercial properties — from the retail spaces along Water Street to the medical and professional offices near the Route 101 corridor — need scheduled cleaning that doesn’t disrupt business hours. We work early mornings and weekends, and we bring the same commercial-grade equipment we use in Lowell’s larger facilities. For restaurants and food service near the river, where humidity control is already a challenge, we pay particular attention to return plenums where grease and moisture combine to create stubborn buildup.
Supply Duct Cleaning
Supply ducts deliver conditioned air to your living spaces, and in Exeter, they’re often the first place we find visible mold. The supply runs in historic homes frequently pass through uninsulated chases in exterior walls or through below-grade cellar spaces that stay cool and damp year-round. We clean supply ducts with Rotobrush contact cleaning plus negative air HEPA extraction, then inspect for post-cleaning integrity. If we find deterioration in the duct liner from long-term moisture exposure, we’ll show you the video and explain your repair options.
Return Duct Cleaning
Return ducts pull air back to your HVAC unit, and they’re the system’s lungs — when they’re clogged with decades of accumulated dust, pet dander, and pollen from Exeter’s dense tree canopy, your entire system works harder. Return plenums in older Exeter homes are often sheet-metal boxes in basements or crawl spaces, and they’re prone to corrosion and microbial growth from ground moisture. We clean these thoroughly and check for air leaks that could be drawing unconditioned, humid basement air into your system.
Full System Cleaning
Our most comprehensive service for Exeter properties — we clean every accessible component of your duct system, from main trunk lines to branch ducts, registers, and grilles. For homes near the Squamscott floodplain, this is often the right starting point, since partial cleaning can leave contaminated sections that re-inoculate the rest. We finish with a full video inspection so you see what we see.
Video Inspection
Before we quote any significant cleaning in Exeter, we offer video inspection of your duct interiors. This is especially valuable for historic homes where the duct routing is unknown or where previous owners may have made modifications. The camera shows us mold, debris accumulation, disconnected sections, and structural deterioration — and it shows you, too, so there’s no guesswork in our recommendations.

Trusted Brands We Service in Exeter
We clean and service duct systems connected to all major HVAC brands, and for air quality and sanitizing work, we install and maintain Honeywell, Aprilaire, and Guardsman products. These aren’t generic units — they’re the same platforms we use in commercial and remediation-grade applications, now sized for residential systems. For Exeter customers dealing with persistent moisture issues, an Aprilaire whole-home dehumidifier integrated with your duct system can address the root cause that cleaning alone won’t fix. We stock common components and can typically return for installation within a few days of your cleaning.
Common Air Duct Cleaning Problems We See in Exeter Homes
- Seasonal storm surge moisture infiltration. When the Squamscott River runs high, older homes in the flood-adjacent neighborhoods see moisture pushed into duct chases through foundation gaps and cellar bulkheads. That moisture doesn’t dry quickly in below-grade stone cellars, and mold blooms in hidden supply runs that homeowners never see until we put a camera in.
- Unsealed retrofit connections in pre-1900 homes. The colonials and Federal-style homes near the historic district often have ductwork that was cobbled into place decades after original construction. Connections between sections are frequently unsealed or supported with failing strapping. Cleaning these systems without first identifying weak points can detach sections entirely.
- Post-storm debris contamination through leaky envelope points. Exeter sees coastal storms that drive rain and debris through roof vents, chimney chases, and attic vents. That material finds its way into return ducts, and standard cleaning protocols may not address the fine particulate that settles in remote branches.
- Biological growth in river-humidified duct liners. The combination of Exeter’s elevated ambient humidity and cool cellar temperatures creates near-ideal conditions for mold colonization on fiberglass duct liner and sheet-metal interiors alike. We see this more consistently in Exeter than in any inland town we serve.

FAQs — Air Duct Cleaning in Exeter
Exeter’s tidal river location means consistently higher humidity that infiltrates older duct systems and promotes mold growth at rates inland towns simply don’t experience. We approach Exeter jobs as moisture-remediation concerns first, debris removal second — using HEPA-contained equipment and post-clean inspection protocols that account for biological growth, not just dust. Call (877) 517-5646 and we’ll assess your specific duct environment.
Yes — our mold-remediation protocol uses Abatement Technologies negative-air HEPA containment and contact cleaning with appropriate antimicrobial application where indicated. In the historic district, we cleaned a 1780s Federal-style home where the supply duct ran through a stone cellar two feet from the Squamscott floodplain. Using Rotobrush and Abatement Technologies HEPA filtration, we removed heavy black mold from the interior liner; the homeowner hadn’t noticed any odor despite visible growth. For Exeter’s river-humidified duct systems, this level of intervention is often necessary rather than optional.
Yes, with the right protocol — we video-inspect first to map duct routing and identify weak connections, then use controlled-contact cleaning rather than aggressive mechanical methods. Pre-1900 Exeter homes have ducts that were never designed into the original structure, so we treat them as fragile retrofit systems that require technician judgment, not automated equipment. Call (877) 517-5646 to schedule an inspection; we’ll show you exactly what we’re working with before we touch anything.
Yes — we offer video inspection for $150–$250, fully credited toward your cleaning if you proceed. For Exeter’s older homes with unknown duct configurations or suspected moisture damage, this step prevents surprises and ensures we quote accurately. Thomas Hernandez performs the inspection personally, and you’ll see the footage in real time. Call (877) 517-5646 to book.
Schedule an inspection immediately — musty odors after high water indicate moisture has entered your duct system and microbial growth is likely active. Don’t run your HVAC continuously; the airflow can spread spores throughout the home. We prioritize post-storm calls from Exeter’s flood-adjacent neighborhoods and can typically inspect within 24 hours. Call (877) 517-5646 — estimates are free, and delaying inspection often makes remediation more extensive.
