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.

Why Hollis Air Duct Cleaning Is West Haven’s Preferred Air Duct Cleaning Company
We’ve built our reputation in West Haven on showing up inside the window, pricing in writing, and leaving the site clean. That’s The Garrison Standard, and it applies to every job we run in this city.
Our technicians are background-checked and uniformed, and we use the same equipment commercial crews do: Rotobrush rotary brush systems for agitation, Nikro negative-air machines for containment, and filtration products from Honeywell and Aprilaire. When we clean ducts in a 1920s three-family near Campbell Avenue or a post-war ranch off Sawmill Road, we’re working with the actual layout of that house, not a generic checklist.

Vent Cleaning in West Haven
Vent Cleaning in West Haven means more than brushing off a grille. In this city, supply vents in beach neighborhoods often show black mildew rings where humid, salt-laden air condenses against cooler duct walls, and return vents in basement-level units pull musty air through damp sheet-metal trunks. A proper vent cleaning here removes the visible buildup and the microbial layer behind it.
For a typical West Haven home, vent cleaning as a standalone service runs $180 – $340 for 10 – 15 vents, or it’s bundled into a full system cleaning. We don’t price per vent because that’s how the invoice doubles once the van is in your driveway. One flat price per system, agreed before we start.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms. In West Haven’s older capes and ranches, these often run through unconditioned attics or exterior walls where summer humidity meets winter cold, creating condensation points. We remove each grille, brush the duct throat with rotary tools, and extract debris under negative pressure so nothing drifts into your living space.
Return Vent Cleaning
Return vents pull air back to the handler. In West Haven’s multi-families and subdivided homes, these are where we most often find the real problem: mildew coating the duct walls, fed by basement dampness and poor airflow. Cleaning the return without addressing the source is a temporary fix. We flag it, show you the camera footage, and recommend what actually solves it.
Air Duct Repair in West Haven
Air Duct Repair in West Haven addresses the gaps, disconnects, and corrosion that develop in aging duct systems exposed to coastal conditions. Original sheet-metal trunks in basements and crawlspaces rust at the seams where humidity pools. Flex duct in newer additions sags and tears. We seal with mastic, replace damaged sections, and restore airflow balance so your system doesn’t overwork itself.
Typical air duct repair in West Haven runs $350 – $800 for sealing and sectional replacement, or $1,100 – $2,400 for more extensive trunk line work in older homes with difficult access. Every repair gets a written price upfront and falls under the 365-Day Done Right Promise.
Duct Sealing and Mastic Application
Leaky ducts pull basement air, radon, and moisture into your supply stream. In West Haven’s low-lying areas, that basement air carries mold spores and flood residue. We seal joints and seams with duct mastic, a brush-applied compound that flexes with temperature changes and outlasts tape. A sealed system also improves efficiency, since you’re not heating or cooling your crawlspace.
Sectional Replacement and Access Creation
Some West Haven homes have original ductwork that’s too corroded or too poorly laid to salvage. We cut access panels where needed, replace damaged trunk sections with insulated duct, and close the work properly so it doesn’t leak or rattle. Before-and-after photos show you what was done and why.
Trusted Brands We Service in West Haven
We carry and install filtration and cleaning equipment from Honeywell, Aprilaire, and Abatement Technologies, the same brands used in commercial and healthcare settings. For West Haven homeowners dealing with coastal humidity, we stock Honeywell whole-home dehumidifiers and Aprilaire media filters that capture mold spores and salt particulates before they circulate. Parts are available through our Hartford coordination office, so replacement and follow-up don’t involve long waits. When we recommend a dehumidifier after cleaning your beach-block ducts, it’s because we’ve measured the crawlspace humidity and know what keeps that ductwork clean through the next humid stretch.
Common Air Duct Cleaning Problems We See in West Haven Homes
- Mildew in return trunks after humid summers. In the beach neighborhoods and low-lying areas along the Sound, our technicians routinely find mold and mildew inside return ducts after summer humidity or storm flooding. The damp biofilm feeds on dust and organic material, and it blows musty odor through the house every time the handler cycles.
- Corroded sheet-metal seams in original basement ductwork. Many West Haven homes built before 1960 have original sheet-metal trunks that rust at the joints where condensation collects. The leaks pull unconditioned basement air into the supply stream and reduce system pressure so rooms at the end of the run never heat or cool properly.
- Flooded crawlspaces contaminating flex duct. After nor’easters push water into low-lying areas, flex duct in crawlspaces becomes a reservoir for mold and sediment. Even after the water recedes, the duct liner retains moisture and re-contaminates the air until it’s removed or thoroughly dried and treated.
- Ignored air handlers growing mold on evaporator coils. Coastal humidity lets mold colonize the wet evaporator coil and drain pan inside the air handler. Cleaning only the ducts while ignoring the blower compartment and coil leaves the source intact, so the problem returns within weeks.

FAQs About Air Duct Cleaning in West Haven
West Haven’s location on Long Island Sound means higher humidity, salt-laden air, and more basement dampness than inland towns like Wallingford see. Your sister’s ducts may have dust, but your return trunks are likely growing mildew fed by coastal moisture that condenses inside cool metal ductwork. We see this pattern consistently in West Haven’s beach neighborhoods and low-lying areas. Call (361) 326-5060 and we’ll camera-inspect to confirm.
A genuine cleaning physically removes the biofilm, dust, and spores that feed mold growth, using agitation tools and negative-air extraction. Fogging a sanitiser without source removal only kills surface growth on the duct walls; it leaves the damp biofilm and organic material intact, so the musty smell returns by the next humid stretch. In West Haven’s climate, source removal is the only approach that lasts. We show you the before-and-after camera footage so you know the difference.
If water reached your crawlspace or basement ductwork, you likely need inspection and likely cleaning. Floodwater carries sediment and organic material into duct systems, and even after the water recedes, the damp liner supports mold growth that circulates through the house. We camera-inspect flooded systems, clean and treat what needs it, and recommend dehumidification to prevent re-contamination. Call (361) 326-5060 for a free post-flood duct assessment.
We clean the air handler, blower motor, evaporator coil, and drain pan on every full system cleaning. In West Haven’s humid coastal climate, mold colonizes the wet evaporator coil and drain pan more readily than in drier inland areas. Cleaning only the ducts while ignoring the handler leaves the source of contamination running. Our full system cleaning includes the entire air path, and we document it with before-and-after photos.
Yes. We’ve cleaned original sheet-metal trunks in West Haven’s 1920s capes, 1950s ranches, and subdivided three-families. When access is tight, we cut proper access panels, complete the work, and seal them correctly so the system doesn’t leak or rattle. We show you the camera footage from inside those ducts so you see what we found and what we removed. Call (361) 326-5060 to schedule a free inspection.
