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 Air Duct Cleaning Across New Haven
Air duct cleaning in New Haven typically runs $350 – $650 for a full residential system and $800 – $2,400 for commercial jobs, with most homes completed in a single visit. Our crews are dispatched from the Hartford office and serve New Haven neighborhoods directly, carrying the same Rotobrush and Nikro equipment we use on commercial sites throughout the state. We’ve worked in the three-deckers of Fair Haven, the bungalows of Westville, and the post-war ranches of West Rock enough to know that New Haven’s housing stock doesn’t respond to a one-size-fits-all approach.

Why Hollis Air Duct Cleaning Is New Haven’s Preferred Air Duct Cleaning Company
We’ve been part of the Garrison Partners family since 2004, and our Air Duct Cleaning in New Haven crews have built a reputation by showing up inside the window, pricing in writing, and leaving the site clean. New Haven homeowners don’t need another coupon in the mailbox promising a $79 whole-house special that balloons to $600 at the door. They need a crew that treats a Fair Haven three-decker with the same discipline as a commercial job downtown.
Our technicians are background-checked and uniformed, and they work to The Garrison Code: arrive squared away, explain what the camera shows, quote the full job before touching a tool, and finish with before-and-after photos of your own ducts. The 365-Day Done Right Promise covers every job in writing. If the work fails within a year, we return and make it right at no charge, including a free second visit. Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
HVAC Duct Cleaning in New Haven
HVAC Duct Cleaning in New Haven means source removal from the entire forced-air system: supply trunks, return plenums, branch lines, and the air handler cabinet, using negative-air machines and rotary brush systems designed for the kind of accumulation these older homes hold. A typical residential HVAC duct cleaning in New Haven runs $350 – $650, with multi-zone systems or heavy contamination toward the upper end. Most single-family jobs take 3 – 5 hours. We see the worst buildup where original gravity-furnace ducts were converted to forced-air in the 1950s and 60s, leaving low-velocity trunk lines that never moved enough air to self-clean.
Full System Source Removal
We connect a Nikro negative-air machine to your trunk line and run a Rotobrush rotary system through each branch, pulling dislodged debris back through a HEPA-filtered vacuum rather than blowing it into your living space. In New Haven’s pre-war multi-families, this matters because decades of coal dust and soot have compacted into porous seams that compressed air alone won’t touch.
Camera Inspection Before and After
Our techs feed a duct camera through the system before quoting and again after cleaning. Homeowners in Westville and West Rock have used these images to document crushed flex-duct runs or disconnected branches that explained why certain rooms never heated evenly. The camera doesn’t lie, and we don’t quote sealing work you don’t need.
Vent Cleaning in New Haven
Vent Cleaning in New Haven focuses on the registers, grilles, and the immediate boot connections where visible dust accumulates and where exterior debris first enters the living space. A standard vent cleaning as part of a full system job runs $75 – $150 for register-level work, though we don’t price per-vent. The full-system quote covers every supply and return point. Homeowners often notice vent cleaning matters most in July, when elm seeds and maple helicopters have clogged exterior intake screens and airflow drops enough to freeze the evaporator coil.
Exterior Intake and Vent Cap Clearing
New Haven’s street-tree program keeps the canopy thick over streets like Whitney Avenue and Orange Street. That greenery drops seeds into high side-wall vents faster than most systems can filter. We clear these intakes as standard practice before interior work begins. It’s not an upsell. It’s part of doing the job by the book.
Register and Boot Detailing
We remove each register, clean the boot and the first few feet of branch line, and inspect for mold staining or rust that indicates moisture intrusion from the humid New Haven summer. In homes near the shoreline or tidal rivers, we also check for salt corrosion on metal components that accelerates faster here than inland.
Trusted Brands We Service in New Haven
Our trucks stock filtration and sealing products from Aprilaire, Abatement Technologies, and Guardsman, the same brands commercial HVAC contractors specify for schools and medical buildings in the New Haven metro. We don’t run to a supply house mid-job. If your system needs a new vent cap in West Haven or a sealed return plenum in East Rock, the parts are on the van. That keeps the job moving and the price locked to what we wrote down before starting.
Common Air Duct Cleaning Problems We See in New Haven Homes
- Crushed or disconnected flex-duct in student rentals. In Fair Haven and Wooster Square, tenant turnover renovations often leave flex runs cracked or completely separated in ceiling cavities. A camera inspection finds the break; cleaning alone won’t fix it, but our duct sealing with mastic restores airflow and keeps the system from overworking.
- Coal-dust and soot residue in pre-war supply runs. In East Rock and Fair Haven Heights, we still find original coal-furnace deposits coating the inside of galvanized ducts. Surface wiping won’t remove it. We use negative-air source removal with HEPA containment so the debris doesn’t redistribute through your home.
- Rust and condensation in uninsulated attic and crawlspace runs. New Haven’s cold winters cause moisture to condense on cold metal ducts, especially where foundation vents are blocked. Rust scale flakes into the air path and loads up filters. We document the damage and can recommend insulation or sealing if the metal is structurally sound.
- Elm and maple seed clogging of exterior intakes. The city’s dense canopy fills side-wall and soffit vents with organic debris that restricts airflow, raises static pressure, and leads to frozen coils in summer. We clear these intakes and install better screening where the original cap has failed.
Pricing for Air Duct Cleaning in New Haven, CT

In New Haven’s market, a typical residential full-system air duct cleaning runs $350 – $650 for a single-family home up to about 2,500 square feet.

Commercial duct cleaning in New Haven starts around $800 and scales with system complexity, typically $800 – $2,400 for small to mid-size buildings.
What moves the price: the number of air handlers, accessibility of trunk lines in crawlspaces or attics, whether camera inspection reveals disconnected runs requiring sealing, and the level of contamination.

FAQs About Air Duct Cleaning in New Haven
Your coil froze because restricted airflow dropped the temperature below 32 degrees at the evaporator. In New Haven, the most common cause is elm and maple seeds clogging exterior intake vents, a problem we see every summer from East Rock to Westville. We clear those intakes and clean the blower assembly as part of our standard full-system work. Call (361) 326-5060 if your system is freezing now; restricted airflow can damage the compressor.
We typically find a mix of original galvanized trunk lines from a 1950s forced-air conversion, later flex-duct branches that have cracked at joints, and accumulation from decades of tenant turnover without cleaning. The camera often shows disconnected runs in ceiling cavities where a renovation crew cut corners. We quote sealing work separately if the disconnection is beyond what cleaning can address, always with a written price before we start.
Yes. In homes built before the 1940s that still have original supply runs, we regularly find compacted coal soot and dust residue from furnaces removed 60 or 70 years ago. It requires source removal under negative pressure with HEPA filtration, not a surface wipe. Without proper removal, a new MERV-rated filter will load up within weeks of installation.
Humid summer air condenses on cool metal surfaces in below-grade ducts and crawlspaces, promoting mold and rust. Winter cold causes condensation on the interior of uninsulated attic runs, especially where warm moist house air meets freezing metal. The freeze-thaw cycle at exterior penetrations, combined with ponding ice, accelerates corrosion. We inspect for these conditions during every job and document what we find.
The EPA states that duct cleaning has never been shown to prevent health problems, and no research conclusively proves that particle levels in homes increase because of dirty air ducts. However, the EPA does recommend cleaning if there is substantial visible mold growth, rodent or insect infestation, or if ducts are clogged with excessive debris and particles actually releasing into the home. We show you what the camera sees and let you decide, with no pressure to proceed.
