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 Derry Village
HVAC cleaning in Derry Village usually means more than running a brush through ducts. In this part of town, the job often includes sealing gaps in fieldstone foundations, pulling decades of birch pollen out of return plenums, and photographing every duct run before and after so you can see the work was actually done. CleanRun Air Duct Cleaning serves Derry Village homeowners with written pricing before any work starts and a documented photo record when the crew leaves. Call (806) 606-6902 to schedule.
Why CleanRun Air Duct Cleaning Is Derry Village’s Preferred HVAC Cleaning Company
We approach HVAC Cleaning in Derry Village differently than most companies do. Our technicians know what lives inside the ductwork of a 1790s colonial off Thornton Avenue versus a 1978 ranch near Pinkerton Street. The systems are not the same, and the cleaning should not be either. Every job starts with a written price under Haven Standard Clause 1, so there is no bait-and-switch moment when the van pulls up. You know the number before a single panel comes off.
As Derry Village residents ourselves, we understand the town’s split personality: two-hundred-year-old center homes with fieldstone basements and retrofitted forced air, sitting minutes from tract subdivisions built during the I-93 commuter boom. That local knowledge means we check what actually matters here: unsealed wall penetrations, crawlspace duct sections, and radon pathways in stone foundations.
Tomas Reyes founded CleanRun in 2013, and the brand has served 52,000+ homes since, every one with written pricing and a photo record. That consistency is why Derry Village homeowners bring us back when it is time for the next cleaning or sealing job.
Our HVAC Cleaning Services in Derry Village
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler and is where the system actually cools air. In Derry Village, summer humidity in the Merrimack Valley corridor means coils here run wet for weeks at a time, collecting a layer of dust, pollen, and occasionally biological growth. A fouled coil raises energy use and reduces cooling output. We clean coils with a non-acidic treatment matched to the coil material, then photograph the result.
Blower Cleaning
The blower motor and wheel move conditioned air through your ducts. When the blower is caked with debris, it works harder, moves less air, and shortens motor life. In older Derry Village homes where return ducts pull air through stone foundations, the blower often collects fine stone dust, soot, and pollen. We remove the blower assembly, clean it with professional-grade equipment, and reinstall it balanced and tested.
Condenser Cleaning
The condenser is the outdoor unit. Derry’s dense mixed hardwood and pine canopy drops a lot of material: cottonwood seed, maple samaras, pine needles. These collect on the coil fins and restrict airflow, which drives head pressure up and makes the compressor run hotter than it should. We clean condenser coils with a low-pressure wash and fin-safe method, and we check the surrounding clearance so the unit can pull air properly.
Air Handler Cleaning
The air handler houses the blower, evaporator coil, and often the filter rack. In a retrofitted Derry Village cape, the air handler may be wedged into a closet or attic space never designed for it. Cleaning the ducts while skipping the air handler leaves the source of most airborne debris untouched. We clean the cabinet interior, coil, drain pan, and condensate line, then seal any gaps that let attic or crawlspace air bypass the filter.

Common HVAC Cleaning Problems We See in Derry Village Homes
- Unsealed penetrations through stone or concrete foundation walls. Older Derry Village homes often have duct runs pushed through fieldstone basements with gaps around the duct. These gaps pull in soil gas, radon, cold air, and crawlspace dirt, loading the duct with debris even after a fresh cleaning.
- Debris loosened but not extracted. Agitation tools that shake debris loose without proper negative-pressure extraction send dust back into supply and return ducts, where it settles and re-enters the living space. We use HEPA-filtered negative-pressure capture during source removal so debris leaves the home.
- Moisture in crawlspace duct sections. Summer humidity across the Merrimack Valley encourages condensation inside uninsulated ducts that pass through crawlspaces. A cleaning that ignores this leaves the conditions for future mold regrowth in place.
- Decades of original ducts in 1970s and 1980s ranches. Many Derry Village ranches built during the I-93 commuter expansion still run original galvanized or early flex ductwork that has never been cleaned. In homes on unpaved roads, a significant share of what we pull out is road dust and fine granite grit.
Pricing for HVAC Cleaning in Derry Village, NH
HVAC cleaning in Derry Village typically runs from $425 to $1,100 depending on system size, access difficulty, and whether sealing or sanitizing work is included. A straightforward blower and evaporator coil cleaning on a 1970s ranch runs $400 to $650. A full air handler cleaning with duct sealing in a multi-run colonial runs $750 to $1,100. Homes with heavily retrofitted systems and stone wall penetrations often fall at the higher end because the sealing step cannot be skipped. Every price is written before work begins. No per-vent pricing, no pressure-sale add-ons, and no number that changes once we are inside. Call (806) 606-6902 for an exact written quote.

FAQs - HVAC Cleaning in Derry Village
Older Derry Village homes need sealing as part of any HVAC cleaning because retrofitted ducts were often pushed through fieldstone or poured-concrete basement walls without proper seals. Those penetrations let radon, soil gas, and crawlspace air enter the duct system and get distributed through the living space. Cleaning removes accumulated debris, but without sealing the pathway, the system pulls the same material back in within days. We cleaned a forced-air system in a 1790s colonial off Thornton Avenue where the return duct had been squeezed through a fieldstone wall with a gap big enough for a fist. Our camera inspection showed birch pollen and crawlspace dirt packed around a Honeywell air handler, so after source removal with HEPA filtration, we sealed the penetration and treated the evaporator coil; the home’s radon levels dropped below 4 pCi/L within a week. That is the difference between a surface job and a real fix. Call (806) 606-6902 to schedule a look at your system.
Homes on unpaved roads in Derry Village should schedule HVAC cleaning every 24 to 36 months, compared to the 3-to-5-year interval that works for many homes in paved subdivisions. Road dust from unpaved surfaces is finer than household dust and carries granite grit that abrades blower bearings and clings to coil fins. Pine pollen adds to the load each spring. If the home also runs a wood stove or wood furnace, the interval drops closer to 18 to 24 months, because wood smoke particulates accumulate faster and combine with road dust in the return plenum. Call (806) 606-6902 for a written quote.
Cleaning alone does not reduce radon, but cleaning combined with sealing the duct penetrations through the fieldstone basement wall often does. Radon enters a living space through unsealed gaps in basement walls, and when a duct passes through such a wall without a proper seal, it acts like a conduit. Sealing around the duct penetration as part of the cleaning job closes that pathway. The result depends on the home, but the 1790s colonial we worked on off Thornton Avenue measured below 4 pCi/L within a week after we sealed the return duct penetration. That is the radon-related step most generic cleaning services skip, and it is one reason we make duct sealing part of the job scope whenever a camera inspection shows an unsealed wall pass-through. Call (806) 606-6902.
The most common problem with 1970s and 1980s ranch ducts in Derry Village is dust and debris accumulation on top of aging galvanized or early flex duct sections that have never been cleaned. Many of these homes were built during Derry’s I-93 commuter expansion, and their duct runs are original. Over 40 to 50 years, that means layers of road dust, pet dander, and pollen compacted inside the ducts, especially on homes near unpaved roads. We also find early flex duct that has sagged, separated, or collapsed in crawlspaces, creating air gaps that pull damp air into the system during humid summers. Our process includes removing the accumulated debris with HEPA-filtered negative pressure, then checking for moisture damage and resealing separated duct sections.

Yes, the air handler should be cleaned when the ducts are cleaned, not treated as an afterthought. In a Derry Village cape with retrofitted central air, the air handler is usually tucked into a tight closet or attic space, and it collects the same pollen, dust, and debris that accumulate in the ducts. Cleaning ducts while skipping the air handler leaves the blower wheel coated and the evaporator coil fouled, which means the system still moves dirty air and works harder than it should. Our air handler cleaning removes the blower, cleans the cabinet interior and coil, flushes the condensate drain, and reassembles everything. The photo record shows the inside of the air handler before and after, not just the ducts. Call (806) 606-6902.
Derry Village homes are not all the same, and your HVAC cleaning should not be either. Whether you are in a 1790s colonial with a fieldstone basement or a 1980s ranch off East Broadway, we will give you a written price before any work starts, a documented photo record of every duct run when we are done, and a 365-Day Done Right Promise in writing that holds long after the truck leaves.
