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.
Fast, Reliable Air Duct Repair Across Boston
Air duct repair in Boston typically runs $350 – $900 for a focused repair on one section, and $1,200 – $3,800 when a full replacement of deteriorated flex runs is required across a triple-decker. Most Boston jobs we see involve collapsed or disconnected ductwork in retrofitted pre-war buildings, not simple leaks. We know the layouts, the tight access points, and what these old houses throw at you. Call (980) 447-2498 and we’ll give you a written price before any work starts.
Boston’s housing stock is not like the rest of the country. Triple-deckers, rowhouses, and converted Victorians were built for radiators, not forced air. When central air was retrofitted decades later, the ducts got squeezed into closets, basement ceilings, and wall cavities no one was meant to access. That means the repair work here is different from what a suburban house needs. If you live in Dorchester, Roxbury, Jamaica Plain, or South Boston, you already know the drill: a register blows weak, a bedroom never cools, or a musty smell comes through when the heat kicks on. We fix exactly those problems, and we do it without tearing open more of your house than necessary.

Duct Replacement in Boston
Duct Replacement in Boston is usually the right call when the original flex duct has collapsed, torn, or pulled away from its connections after decades inside uninsulated wall cavities and basement ceilings. In retrofitted triple-deckers across neighborhoods like Dorchester, Jamaica Plain, and Southie, we often find runs that were installed in the 1990s and have since deteriorated to the point where air is pouring into the void behind a closet wall instead of reaching the registers. For a single run, expect to pay roughly $450 – $950. Replacing all the accessible runs on one floor typically lands between $1,200 and $2,800 in Boston.
When a Patch Won’t Do
Some duct damage can be sealed and reinforced. But when the inner liner of flex duct has collapsed, the only real fix is removal and replacement. We show you camera footage of the damaged section so you can see exactly what we saw before you approve the work.
Documented Before and After
Replacement work we do in Boston includes before-and-after photos and a written report of what was changed. If the repair involves a run you can’t see behind a closet wall, you still get documentation of what went in and what came out. No mystery work, no “trust us” line.
Ductwork Installation in Boston
Ductwork Installation in Boston usually refers to adding or extending runs when a homeowner has converted a space or when a previous retrofit never properly served certain rooms. In a three-decker on a tight Cambridge or Somerville side street, we often see second- and third-floor bedrooms that never got adequate supply because the original retrofit simply tapped a trunk line without proper sizing. Adding a properly sized run and balancing it to the air handler in a Boston home typically costs $800 – $2,200, depending on access and run length.
Runs Through Converted Closets and Ceilings
Boston’s pre-war buildings rarely have open basements with easy overhead access to every floor. Runs snake through converted closets, under stair landings, and across basement ceilings. We plan installation around the access that exists, and we tell you before we cut anything where we’re cutting and why.
Retrofitting Old Spaces Correctly
If a previous owner added central air to a triple-decker without balancing the system, you feel it as uneven temperatures floor to floor. We install and replace runs with static pressure in mind, using a manometer to confirm that the air handler isn’t fighting the ductwork. The goal is a system that actually reaches the far bedrooms, not one that just makes noise.
Trusted Brands We Service in Boston
Our Boston crews run professional-grade equipment from Rotobrush and Nikro, and we work with air-quality products from Aprilaire and Abatement Technologies. When we replace a section of duct in a Dorchester triple-decker or a Jamaica Plain single-family conversion, we’re using materials and tools built for the kind of tight, awkward access these buildings demand. We carry common replacement parts and components on the truck, so a single visit can often handle both the diagnosis and the repair. For Boston homeowners with aging systems, we can also recommend and install Aprilaire media filters after the ducts are sealed and balanced.
Common Air Duct Repair Problems We See in Boston Homes
- Trunk lines run through converted closets with 90-degree sweeps at every floor and no cleanout access. These sections often go untouched from the day they were installed, and the only way to see what’s inside is a camera inspection. We find collapsed sections here that never produced a visible symptom at the register.
- Deteriorated 1990s-era flex duct stuffed into basement ceilings and wall cavities. The inner liner separates and collapses inward, restricting airflow without any obvious tear in the outer jacket. The register looks fine, but the room never gets comfortable.
- Disconnected or poorly sealed branch runs in basement ceilings. In Boston’s older wood-frame homes, seasonal expansion and contraction works connections loose. Air leaks into the joist bays instead of reaching the rooms above.
- Mold and biological growth driven by Boston’s summer humidity. Buildings near the Atlantic absorb moisture, and ducts in uninsulated cavities without vapor barriers stay damp longer than they should. When we see growth on an inspection camera, we recommend replacement rather than a surface clean in many cases.

FAQs About Air Duct Repair in Boston
Yes. In a triple-decker with three separate air systems, we price each system separately. A rental unit on the first floor and an owner’s unit on the third floor are different jobs with different pricing. That way a landlord or owner-occupant doesn’t pay for work that only benefits one tenant. Our written price is per system and stays the same from quote to final invoice.
You should get before-and-after photos, a written description of what was repaired or replaced, and a written guarantee covering the work for 365 days. We provide all three on every repair job. If the covered repair fails within that window, we return at no charge under the 365-Day Done Right Promise. Call (980) 447-2498 and we’ll walk you through what our documentation includes.
Often yes. We use extended camera inspection and agitation tools that can be fed through existing register openings, attic hatches, and basement ceiling gaps. In a three-family on Pleasant Street in Dorchester, we reached a collapsed second-floor run by extending our gear down from the attic access because the converted closet had no panel. When new access is truly required, we tell you exactly where and why before any cutting happens.
Cleaning removes debris from the inside of a duct. Repair fixes structural problems: collapsed flex runs, disconnected joints, or sections that were never sealed properly. In Boston’s pre-war buildings, decades of tight retrofits mean the structural problems are more common than heavy dust buildup. If our camera inspection finds a collapsed run, we’ll show you the footage and recommend repair before any cleaning makes sense.
Yes. Boston’s proximity to the Atlantic drives above-average summer humidity, and older buildings without modern vapor barriers hold moisture in wall cavities and basement ceilings. If we find mold colonization inside a duct run during repair, we recommend replacing that section rather than sealing it and hoping for the best. The decision is documented with camera footage so you can see the reasoning yourself. Call (980) 447-2498 to schedule an inspection and we’ll give you an honest assessment of what your ductwork actually needs.
