We’ve worked in Boston for over 42 years. That means we’ve cleaned systems in the brick row houses along Beacon Street, the converted lofts near Fort Point, and the triple-deckers in South Boston. We know the difference between a purpose-built duct system and one that was shoehorned into a 130-year-old wall cavity. And we know that in this city, a standard cleaning rig often isn’t enough.
Why Bellows Air Duct & Vent Co. Is Boston’s Preferred HVAC Cleaning Company
Ray Castillo has led Bellows Air Duct & Vent Co. since its founding in 1984, and our reputation in Boston is built on returning until the job is right. Our 90-Day Done Right Promise means no paperwork, no arguing - if something isn’t right, we come back at no charge. That promise is stamped on every job, and it’s why homeowners in Boston call us back when they move to a new place.
We answer our phones with a live person, 24/7. Not a voicemail tree, not an app. When a Back Bay homeowner calls at 6 p.m. because their vents are blowing dust after a humid August day, someone picks up and schedules the visit. Most Boston appointments are available within 24-48 hours, and emergency service moves faster.
Our technicians are background-checked and uniformed, and they carry equipment from Rotobrush and Abatement Technologies - the same brands serious HVAC contractors specify. Before any cleaning begins, we run a camera through your ductwork. After we’re done, we run it again. You see the record, not just our claim.
We don’t use bait coupons or scare tactics. The price we quote on the phone is the price on the invoice. That’s been our practice for 42 years, and it’s not changing.
Our HVAC Cleaning Services in Boston
Evaporator Coil Cleaning
Boston’s coastal humidity - running 60-70% through July and August - forces air conditioners to work harder and longer than inland systems. The evaporator coil sits in that moist airflow for months, collecting biofilm and microbial growth that standard filters miss. In older Boston buildings with retrofitted ductwork, the coil often sits in a basement air handler with inadequate return filtration, accelerating the problem. We remove the coil assembly when accessible, clean it with pressurized foaming agents, and verify with a camera that the fins are clear. A typical evaporator coil cleaning in Boston runs $180-$340.
Blower Cleaning
The blower motor and squirrel cage are the lungs of your system. In Boston’s Victorian-era housing stock, blowers often run in dusty basement environments with irregular return pathways that pull debris from wall cavities and floor voids, not just filtered indoor air. We remove the blower assembly, clean the housing and wheel blades, and check motor amp draw before reassembly. A dirty blower can reduce airflow by 30% or more, and in Boston’s tight building envelopes, that means uneven heating, longer run times, and higher gas bills through winter. Blower cleaning in Boston typically costs $160-$290.
Condenser Cleaning
Outdoor condenser coils in Boston take a beating. Winter road salt, spring pollen from the Charles River basin, and cottonwood fluff through June all clog the fins. We clean condenser coils with foaming detergent and low-pressure rinse, straighten damaged fins, and check refrigerant pressures. For Back Bay and South End homeowners with rooftop or courtyard units, we bring portable equipment where truck-mounted rigs won’t reach. Condenser cleaning in Boston generally runs $140-$260.
Air Handler Cleaning
The air handler is where your conditioned air begins its journey, and in Boston’s retrofitted systems, that journey often starts in a cramped basement closet or former coal bin. We clean the entire air handler cabinet, including the drain pan, filter rack, and internal surfaces, then treat with an EPA-registered sanitizer where appropriate. For buildings with smart-home integrated zoning systems, we verify damper operation and sensor calibration before closing up. Air handler cleaning in Boston typically runs $200-$380 depending on access and system complexity.
Coil Treatment
After mechanical cleaning, we apply a coil treatment that inhibits microbial regrowth on evaporator and condenser surfaces. This is particularly valuable in Boston, where seasonal moisture swings create ideal conditions for mold recurrence. Our coil treatment is compatible with all major equipment brands and does not leave a residue that affects heat transfer. We recommend it for any system that has shown prior biofilm growth, and for homes with occupants sensitive to indoor air quality. Coil treatment in Boston runs $90-$150 as a standalone service, or $60-$100 when bundled with full cleaning.

Common HVAC Cleaning Problems We See in Boston Homes
- Irregular retrofitted duct runs that standard rigs can’t reach. In Back Bay brownstones and Beacon Hill row houses, ducts often route through closet cavities, dropped ceilings, and floor voids never intended for airflow. Standard cleaning brushes and vacuum heads can’t navigate these convolutions. We use flexible-drive Rotobrush systems and custom extension tooling to reach debris that other services leave behind.
- Abandoned gravity or steam system connections trapping stagnant debris. When forced air was retrofitted into Boston’s 19th-century housing, original distribution systems were often partially removed and capped, not fully sealed. These dead branches remain connected to live plenums, collecting years of debris and occasionally harboring asbestos-wrapped insulation. We identify these connections with camera inspection before cleaning begins.
- Seasonal moisture swings accelerating mold and biofilm growth. Boston’s humid summers and dry, heated winters create condensation cycles inside ductwork, particularly in basement-level runs. Without proper cleaning and treatment, this moisture feeds microbial growth that recirculates through the living space every time the fan runs.
- Absent or inadequate return-side filtration in retrofitted systems. Many Boston brownstones were fitted with supply ductwork but minimal return infrastructure, relying on building cavities and door undercuts for air path. This bypasses filtration entirely, loading blowers and coils with unfiltered household dust. We identify these deficiencies and recommend appropriate upgrades.

What moves the price? Access difficulty is the main variable in Boston. A basement air handler in a South End loft with a standard stairwell is straightforward. A rooftop condenser on a Beacon Hill four-story walk-up, or a blower tucked behind a built-in bookcase in a renovated brownstone, takes more time and specialized equipment. We assess access during our free estimate and give you the exact price before we start. No changes at the door.
We also offer a permanent 5% Senior and Veteran discount, and our $89 Seasonal Tune-Up is available for systems that need inspection and light maintenance rather than full cleaning. Call (844) 685-6342 for an exact quote - estimates are free.

FAQs - HVAC Cleaning in Boston
Yes. We clean retrofitted duct systems in Boston’s Victorian-era housing regularly, and we’ve developed specialized tooling and techniques for the non-standard runs common in Back Bay, Beacon Hill, and the South End. Our technicians use flexible-drive Rotobrush systems and camera-guided inspection to navigate convoluted pathways through closets, dropped ceilings, and floor voids that standard cleaning rigs cannot reach. Call (844) 685-6342 to schedule a free inspection - we’ll show you exactly what your system looks like inside.
Call us for a camera inspection before any cleaning work begins. In Boston’s inner neighborhoods, we regularly encounter abandoned gravity warm-air or steam distribution branches that remain connected to modern forced-air plenums, and these can contain decades of stagnant debris or asbestos-wrapped insulation. Our technician will identify these connections with a pre-cleaning camera run, document what we find, and recommend the appropriate protocol before disturbing anything. Call (844) 685-6342 - estimates are free.
Yes. North End buildings often have unit-to-unit variation in duct routing that reflects decades of piecemeal renovations and owner modifications. We inspect each unit individually with a camera, adapt our equipment to the specific access points and pathway geometry we find, and clean accordingly. No two units are identical, and we don’t treat them as if they are. Call (844) 685-6342 to schedule service for your building.
Yes, and our coil treatment is compatible with all major smart-home and zoning configurations, including Honeywell and Aprilaire systems common in Boston’s renovated properties. We verify that our cleaning agents and treatment products will not affect sensor calibration or damper operation before application. Coil treatment can be bundled with full system cleaning or added to any service. Call (844) 685-6342 for pricing specific to your system.
We identify suspected asbestos-containing materials during our pre-cleaning camera inspection and stop work until proper abatement protocol can be followed. We do not disturb asbestos-wrapped insulation. If we encounter it, we’ll document the location, advise you on next steps, and can refer you to licensed abatement contractors in the Boston area. Our priority is your safety and the safety of our technicians. Call (844) 685-6342 if you have concerns about your building’s duct insulation.
