Air Duct Cleaning in Medford - One Flat Price, Before-and-After Photos

Air Duct Cleaning in Medford, MA

Dryer vent cleaning in Medford usually costs $129-$189 for a standard single-family home, and the city’s pre-1940 triple-deckers often need it more urgently than newer construction. Those Victorian-era homes in Hillside and West Medford were built for radiator heat, so every dryer vent installed later was retrofit through finished walls with sharp bends that trap lint fast.

Why Medford Homes Are Different

Medford’s residential stock runs heavily toward pre-1940 triple-deckers and late-Victorian single-families, concentrated in Hillside, West Medford, and South Medford. The overwhelming majority were originally built with steam or hot-water radiator systems, which means there was no original ductwork anywhere. When owners retrofitted forced-air heat or central AC from the 1970s onward, contractors threaded ducts through finished plaster walls, cramped attic chases, and uninsulated basement runs in configurations no modern builder would tolerate.

These retrofit systems have spent decades accumulating debris, including fine particles from disturbed horsehair plaster, in duct geometries that standard cleaning equipment struggles to reach. Technicians working in Medford triple-deckers routinely encounter duct runs installed beside original interior stairwells and through kitchen closets, creating inaccessible 90-degree bends and dead-leg branches. Add the Mystic River valley’s elevated humidity in South Medford, and older systems with unsealed sheet-metal joints become prime locations for mold colonization. Boston-area winters force these systems to run continuously for five or more months, loading flex-duct liners with fine particulates at a rate newer suburbs simply don’t see.

Our Main Medford Services

Most Medford homeowners call us first about two things: air duct cleaning and HVAC cleaning. Both jobs are shaped by the city’s retrofit-heavy housing stock and river-valley humidity.

Air Duct Cleaning in Medford

Whole-system air duct cleaning in Medford typically runs $425-$650 for a single-family home with up to 12 duct runs. The camera we snake through your plenum, which is the main distribution box, before we start tells us what we’re actually dealing with. In triple-deckers with converted radiator heat, that often means decades of horsehair plaster dust packed into bends no brush can reach without disassembly. We photograph every run before and after, so you see exactly what came out. Air Duct Cleaning in Medford

HVAC Cleaning in Medford

HVAC cleaning in Medford runs $225-$480 for the blower, coils, and accessible components. The continuous five-month heating season loads blower wheels with fine dust that drops efficiency and pushes allergens through the house. In Medford’s older systems with unsealed joints, we frequently find the blower pulling in attic or basement air that was never filtered in the first place. That’s a fixable problem, and one we document in the photo record you receive with every job. HVAC Cleaning in Medford

Dryer Vent Cleaning in Medford

Dryer vent cleaning in Medford addresses a specific problem: retrofit vent runs through finished plaster walls and tight chases that accumulate lint faster than the short, straight vents in newer construction. In triple-deckers and Victorians where the laundry hookup was added decades after the house was built, the duct path is often 15 to 25 feet long with three or more elbows, and every bend is a lint trap. This is the service we recommend Medford homeowners schedule most frequently, because the alternative is a dryer that runs longer, works harder, and in the worst case, starts a fire. We’ve written about this service in detail on our Dryer Vent Cleaning page.

Dryer Vent Inspection

Signs you need it

Your dryer takes two or more cycles to dry a normal load, or the laundry room feels humid while the machine runs.

What it costs in Medford

A standalone dryer vent inspection in Medford runs $89-$149, and that’s credited toward cleaning if we find a blockage.

How we do it

We run a camera through the full vent run, photograph every elbow and termination point, and show you exactly what’s inside before quoting any work.

Lint Removal

Signs you need it

You see lint accumulating around the dryer base or the outside vent flap doesn’t open fully during a cycle.

What it costs in Medford

Lint removal as part of a full vent cleaning in Medford runs $129-$189 for a standard single-family home with an accessible vent.

How we do it

We use negative-pressure extraction with a Rotobrush system, pulling lint out from the interior termination point while brushing the full run, then photograph the before and after.

What Dryer Vent Cleaning Costs in Medford

Medford’s retrofit-heavy housing stock pushes prices toward the higher end when vent runs are long, have multiple sharp elbows, or terminate at a second or third-story exterior wall. The written price you get before work starts is the price you pay, no matter what we find once the camera goes in.

How often should dryer vents be cleaned in Medford?

Every 12 months for most Medford homes, and every 6 to 9 months in triple-deckers with long retrofit runs or households that do 4 or more loads per week. The city’s older housing stock simply accumulates lint faster than newer construction.

Why does my dryer vent clog so fast in Medford?

Retrofit vent runs through finished walls and tight chases are longer, with more elbows than modern installations. Every bend is a lint trap, and in Medford’s converted triple-deckers, runs of 15 to 25 feet are common. Call (806) 606-6902 for a written assessment.

Duct Repair & Sealing in Medford

Duct repair and sealing in Medford addresses a problem that shows up consistently in the city’s retrofit systems: unsealed sheet-metal joints and flex-duct runs that leak conditioned air into attics, basements, and wall cavities. In a pre-1940 home retrofitted for forced air decades ago, the original installer rarely sealed connections properly, and decades of thermal cycling have made the gaps worse. The result is higher heating bills and rooms that never quite reach temperature. You can read the full scope of this service on our Duct Repair & Sealing page.

Duct Sealing

Signs you need it

Some rooms in your house are noticeably colder in winter or hotter in summer, even with the vents fully open.

What it costs in Medford

Duct sealing in Medford runs $550-$900 for a typical retrofit system with 8 to 12 accessible runs.

How we do it

We locate every leak with a pressure test or visual inspection, then seal joints with mastic and foil tape, photographing each repaired connection.

Flex Duct Repair

Signs you need it

You see crushed, sagging, or disconnected flex duct in your attic or basement, or certain registers barely push any air.

What it costs in Medford

Flex duct repair or replacement in Medford runs $250-$475 per run, depending on access and run length.

How we do it

We replace damaged sections with new insulated flex duct sized to the original specification, then seal both connections with mastic.

What Duct Repair & Sealing Costs in Medford

Medford’s non-standard retrofit layouts often require opening finished walls or ceilings to reach a connection, which pushes cost toward the higher end. You get the written price before any panel comes off, and it doesn’t change based on what we find.

Is duct sealing worth it in an old Medford house?

Yes, especially in pre-1940 homes retrofitted for forced air with unsealed sheet-metal joints. Sealing reduces energy loss into unconditioned spaces and can even out room temperatures. Most Medford systems we test leak 20% to 30% of their air.

Can you repair ducts without opening walls in Medford?

Sometimes. Accessible attic and basement runs can usually be sealed without opening walls. Runs threaded through finished plaster walls may require a small access panel. We’ll tell you in writing what’s needed before any work starts. Call (806) 606-6902.

Air Quality & Sanitizing in Medford

Air quality and sanitizing work in Medford focuses on a specific local condition: elevated humidity in the Mystic River valley, especially in South Medford, which accelerates mold colonization inside ductwork with unsealed sheet-metal joints. Homes near the river and lower-lying sections of the city see this more than anywhere else in Medford. We apply antimicrobial treatments and, where warranted, install UV light systems that address the source, not just the symptom. Full details are on our Air Quality & Sanitizing page.

Mold Treatment

Signs you need it

You smell a musty odor when the heat or AC kicks on, or visible mold appears around vent registers.

What it costs in Medford

Mold treatment for ductwork in Medford runs $350-$600, depending on the extent of the affected area and the system’s accessibility.

How we do it

We photograph the affected areas, apply an EPA-registered antimicrobial treatment to interior duct surfaces, and document the post-treatment condition.

Odor Removal

Signs you need it

A persistent smell, from cooking, pets, or previous occupants, returns shortly after cleaning the house.

What it costs in Medford

Duct odor removal in Medford runs $200-$375 for most single-family systems, with activation typically completed in one visit.

How we do it

We clean the accessible interior surfaces, then apply an odor-counteracting treatment to the full duct run, with before and after photos of the work.

What Air Quality & Sanitizing Costs in Medford

In South Medford, where river-valley humidity is highest, we commonly recommend combining mold treatment with duct sealing to prevent the problem from returning. Every treatment includes a documented photo record with written pricing provided before work begins.

Does mold in Medford ducts come back after treatment?

It can if the underlying moisture problem isn’t addressed. In South Medford’s higher-humidity zones, unsealed joints pull in damp air continuously. Treating the mold without sealing the system often leads to recurrence within a year.

Can UV lights help with mold in older Medford homes?

Yes, UV light installations can reduce mold and bacteria growth inside the coil and ductwork, particularly in systems that run constantly during Medford winters. Installation runs $650-$1,125. Call (806) 606-6902 for a written quote.
