Air Duct Cleaning in Andover, MA
Air duct cleaning in Andover typically costs $350–$650 for a standard residential system, with most jobs completed in a single visit. Andover’s housing stock creates unique challenges you won’t find in neighboring towns: early-20th-century Shawsheen Village brick homes with retrofitted forced-air, and large 1970s–1990s colonials with complex multi-zone layouts stretching through unconditioned attic spaces. Scott Gray handles every job personally, bringing 11 years of focused ductwork experience and professional Rotobrush and Nikro equipment to each home. Call (888) 597-5659 for a free estimate.
Why Andover Homes Are Different
Andover sits at the confluence of the Shawsheen and Merrimack rivers, a low-lying valley that traps humidity during spring snowmelt and nor’easter recovery. This moisture dynamic accelerates mold and particulate buildup inside basement air handlers and flex-duct connections that drier inland suburbs simply don’t face. The town splits between two demanding housing eras: the 1917–1924 American Woolen Company brick homes of Shawsheen Village, where forced-air was retrofitted through walls never designed for it, and the dominant 1970s–1990s colonials on wooded lots, often exceeding 3,000 square feet with duct runs through knee walls and unfinished basements. Both demand specialized equipment and patience that generalist crews rarely provide.
Air Duct Cleaning in Andover
We clean it, repair it, and seal it — not just vacuum over the problem. In Andover, that means starting with video inspection to map non-standard routing before selecting attachments, and accounting for river-valley humidity that resurfaces mold if cleaning doesn’t include proper treatment. Air Duct Cleaning is our core service, and Andover’s conditions have shaped how we perform it.
Residential Duct Cleaning
Andover’s residential split demands two distinct approaches. For Shawsheen Village’s 1920s brick homes, we video-inspect first to map retrofitted ductwork through closets and partition walls, then deploy flex-rod extensions where standard rotary brushes fail. For the town’s large colonials, we account for extended runs with numerous branch connections — more access points, more thoroughness required. A typical single-zone Andover home runs $350–$550; multi-zone colonials run $500–$650. Last October, we found a basement air handler in a Shawsheen Village colonial with a return plenum lined with decades of soot and mold — the homeowner had smelled musty air for three heating seasons before calling.
Commercial Duct Cleaning
Andover’s medical offices near Andover Medical Center and professional buildings in the town center face higher occupancy loads and stricter air-quality requirements than residential. We use Nikro HEPA vacuums and Abatement Technologies air scrubbers to minimize disruption, scheduling most commercial jobs for evenings or weekends. Pricing starts at $800 for small office suites and scales with system complexity.
How much does air duct cleaning cost for a typical Andover colonial?
A 3,000-square-foot Andover colonial with multi-zone ductwork runs $500–$650 for full system cleaning. Single-zone homes in the 01810 ZIP code start closer to $350–$450. The complexity of branch connections in knee walls drives the upper end. Call (888) 597-5659 for an exact quote — estimates are free, and Scott will walk your system with you.
Dryer Vent Cleaning in Andover
Dryer vent cleaning in Andover typically costs $149–$289, with extended runs through knee walls or attic spaces at the higher end. Andover’s longer heating season means dryers work harder October through April, and river-corridor humidity causes lint to clump more densely than in drier climates. Dryer Vent Cleaning here requires attention to configurations that trap moisture and restrict airflow.
Vent Cleaning & Lint Removal
We use Rotobrush brush-system technology paired with Nikro HEPA vacuums to remove buildup without damaging flex-duct sections. Andover’s extended heating season produces denser lint accumulation by spring, and we’ve extracted plugs so saturated with river-humidity moisture they resembled felted wool. Standard single-story cleaning runs $149–$219; multi-story knee-wall or attic runs run $219–$289.
Vent Rerouting
Crushed, sagging, or improperly sloped ductwork needs correction, not just cleaning. We serviced a 1985 colonial where a 35-foot knee-wall run terminated in a crushed flex-to-rigid transition, reducing airflow to 30 CFM. We cleared the plug and installed a Guardsman vent cap with bird guard. Rerouting projects typically range $289–$449.
How often should I clean my dryer vent if I live near the Merrimack River in Andover?
Annually for homes within the river-humidity zone, versus every 18–24 months for drier inland locations. The Merrimack corridor’s elevated humidity causes lint to compact more densely, accelerating blockage. If your vent runs through an uninsulated knee wall or basement rim joist — common in Andover’s 1970s–1990s colonials — annual cleaning is the safer interval. Call (888) 597-5659 to schedule.
HVAC Cleaning in Andover
HVAC cleaning in Andover typically runs $280–$650 for full system service, with basement air handlers and multi-zone layouts at the upper end. The Shawsheen and Merrimack river corridors create localized humidity that hits basement equipment hardest, producing mold colonies standard filter changes never reach. HVAC Cleaning here means disassembling housings and treating what vacuuming alone cannot.
Air Handler Cleaning
We disassemble air handler cabinets, clean drain pans and condensate lines, treat coil surfaces with Guardsman antimicrobial, and verify airflow readings against manufacturer specs. For Andover homes near the Shawsheen River basin, this service routinely reveals mold in flex-duct connections that surface cleaning missed entirely. Basement unit cleaning runs $280–$420.
Evaporator Coil Cleaning
A dirty coil in Andover’s extended heating season means your system works harder for longer, and the cold surface attracts Merrimack Valley pollen and road particulate. We use foaming cleaner followed by low-pressure rinse — never high-pressure washing that bends aluminum fins — then apply treatment that resists future buildup. Coil cleaning runs $180–$320; full multi-component system cleaning runs $450–$650.
Why do Andover basements have more duct mold than those in nearby towns?
Andover’s low-lying valley position traps humidity during spring snowmelt and nor’easter recovery, producing moisture levels in basement air handlers that exceed drier inland suburbs. This localized humidity accelerates mold growth specifically inside plenums and flex-duct transitions. We address it with air handler disassembly, antimicrobial treatment, and source identification. Call (888) 597-5659 for assessment.
Duct Repair & Sealing in Andover
Duct repair and sealing in Andover typically costs $180–$650 depending on scope, with most jobs completed in a single visit. Weak vents, whistling basement air handlers, and uneven upstairs heating all signal leaks wasting energy and circulating unfiltered air. Duct Repair & Sealing fixes what cleaning alone cannot.
Duct Sealing
We seal metal trunk lines with mastic sealant and reinforced mesh, then pressure-test to verify. In Andover, the most significant leaks occur at basement air handler connections and attic knee-wall junctions — exactly where river-valley humidity attacks seals over time. Single-zone sealing runs $280–$480; multi-zone colonials run $450–$650.
Flex Duct Repair
Flex-duct in Andover’s unconditioned attics takes a beating from temperature swings between 20°F January nights and 75°F March afternoons. On a Forest Street colonial, we found flex connections at the air handler loose from moisture cycling, bypassing the Aprilaire filter. We resealed with mastic and reinforced with metal collars. Flex duct repair typically runs $180–$340 per run.
Why do duct repairs in Andover often involve flex-duct separation in attic knee walls?
Andover’s 1970s–1990s colonials frequently run flex-duct through unconditioned attic knee walls, where temperature swings cause expansion and contraction that pulls connections loose. River valley humidity weakens tape adhesives further. We reattach with metal collars and seal with mastic for a permanent fix. Call (888) 597-5659 for an exact quote — estimates are free.
Air Quality & Sanitizing in Andover
Air quality and sanitizing in Andover typically runs $275–$650 for residential mold treatment and bacteria sanitizing, with UV light installation adding $400–$850. Musty air when heat kicks on in October or allergy spikes each spring signal ductwork harboring mold or biofilm that vacuuming won’t eliminate. Air Quality & Sanitizing treats problems at the source.
Mold Treatment
Andover’s river-valley humidity creates ideal conditions for mold inside unconditioned duct runs, particularly knee-wall spaces and basement flex-duct connections where temperature differentials produce condensation. We locate sources with borescope inspection, remove contaminated material with HEPA-contained Rotobrush equipment, then apply Abatement Technologies antimicrobial treatment. Localized basement treatment runs $275–$550; whole-system treatment for large colonials runs $450–$850.
Bacteria Sanitizing
After six months of continuous heating-season operation, Andover ductwork accumulates biofilm that standard vacuuming won’t eliminate. We use EPA-registered agents applied through pressurized fogging, reaching branch connections and return plenums that surface cleaning misses. Most residential systems run $225–$475; whole-home treatments for properties over 3,000 square feet reach $550–$750.
How does Andover’s river-valley humidity affect mold in my air ducts?
Andover’s low-lying position produces spring and fall humidity spikes significantly higher than drier inland suburbs, accelerating mold growth in basement air handlers and flex-duct connections where condensation forms. Your ducts become moisture traps during thaw and storm recovery, particularly in unconditioned knee-wall and basement runs. We address this with targeted mold treatment plus humidity-source identification. Call (888) 597-5659.

What Andover Customers Say
"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
— Rami Hassan"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
— Aisha Boyd"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
