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 HVAC Cleaning Across Woburn
HVAC cleaning in Woburn, MA typically runs $385 – $685 for a standard single-system home when the job includes the supply ducts, return ducts, air handler, blower motor, and evaporator coil. Most Woburn homes we service fall into that range, and we hand you a written price before any equipment comes off the truck. Call (737) 727-2314 and you’ll talk to a live person, not a voicemail tree. From the Horn Pond area to West Woburn and over by the Winchester line, our crews know these houses: older capes with retrofitted duct runs, colonials with finished basements hiding the trunk lines, and the occasional newer build where the builder-grade flex has already sagged. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, and we’ve built our whole operation around one idea: you should know exactly what you’re paying and what you’re getting before we touch a single vent.
Why Cardinal Air Duct Cleaning Is Woburn’s Preferred HVAC Cleaning Company
Woburn homeowners call us because the price we quote is the price on the invoice. No per-vent games, no “discovered issues” once the tech is in your basement. That matters here more than most places because Woburn’s housing stock is heavy on 1950s capes and colonials where duct systems were patched and extended across decades, not designed cleanly from day one. A tech who quotes per-vent on those layouts is quoting you a number that can swing wildly once he sees what’s actually behind the walls. We quote per system, always, and we mean it.
Every booking runs on HVAC Cleaning through the Relay Standard: a live arrival window you can track from your phone, a background-checked uniformed technician whose name you know before he rings the bell, and before-and-after photos of your own ducts delivered by the time we pack up. Omar Haddad leads our crews, and he’s the kind of person who will tell you straight when a cleaning will genuinely help and when it won’t. That honest read is why homeowners around Woburn Center, North Woburn, and the Shaker Glen neighborhood keep our number saved.
Our reputation in Woburn is built on the 365-Day Done Right Promise. If the work isn’t right within a full year, we return and correct it at no charge. That’s not a limited warranty on select jobs. It’s every booking, every time.
Evaporator Coil Cleaning in Woburn
Evaporator coil cleaning in Woburn means pulling the access panel on your air handler, inspecting the coil for the gray mat of dust and pet hair that builds on these things, and cleaning it so your AC actually moves cold air. In Woburn’s older capes, the evaporator coil sits inside a furnace or air handler that may have been installed twenty years ago and not opened since. Coil cleaning here runs $180 – $320 as part of a full system cleaning, or as a standalone job when the coil is accessible and the rest of the system is in decent shape.
How a Dirty Coil Punishes Woburn Homes
A coated evaporator coil forces your compressor to run longer, which pushes your electric bill up and shortens the life of the system. In the humidity we get from late May through September, a dirty coil also condenses more water than it should, and that water carries dust into the drain pan and down the condensate line. That’s how you end up with a pan that overflows onto the basement floor by mid-August.
What Coil Cleaning Involves Here
We remove the access panel, inspect the coil with a camera, and apply a coil-specific cleaner that breaks down the mat without corroding the aluminum fins. Then we flush and extract with HEPA filtration running, so the loosened debris goes into the vacuum, not into the airstream. If the coil is on a furnace that’s seen years without maintenance, we’ll tell you honestly whether a cleaning can restore airflow or whether the coil’s too far gone and a replacement is the smarter money.
AC Duct Cleaning in Woburn
AC duct cleaning in Woburn is the full system treatment: supply and return ducts, trunk lines, branch runs, the air handler, blower motor, and evaporator coil, all cleaned under negative pressure with HEPA filtration running the entire time. For a standard Woburn home, that job runs $385 – $685. The range depends on how many returns your system has, whether the ductwork is accessible from the basement or hidden behind finished sheetrock, and whether the blower needs to be pulled for a thorough cleaning.
What We Find in Woburn’s Older Duct Systems
Houses near the Winchester line and off Cambridge Road frequently have original sheet-metal trunks that were adequate for a 1950s oil furnace but undersized for the central AC retrofitted decades later. Dust, construction debris, and decades of pet dander pack into those returns. When we camera-inspect those systems, we often find disconnected flex runs and returns that have been pulling air from wall cavities, not from the rooms they’re supposed to serve.
The Right Way to Clean AC Ducts
Negative-pressure extraction means the vacuum runs on the system while agitation tools loosen debris inside the ducts. The loosened material flows toward the vacuum, not back into your living room. We run Rotobrush agitation tools and Nikro HEPA filtration on every AC duct cleaning in Woburn, and you see the before-and-after of your own ducts before you sign anything.
Trusted Brands We Service in Woburn
Our techs work on every major system Woburn homes run: Carrier, Trane, Lennox, Goodman, Rheem, Bryant, and the older York and Heil units still heating plenty of capes around town. We keep Aprilaire and Guardsman filtration products on the trucks for homeowners who want better air quality after a cleaning, and our containment and extraction setup runs on Abatement Technologies equipment. If you need a specific filter replacement or a filtration upgrade for a system near Horn Pond or off Main Street, we can usually handle it the same visit. Call (737) 727-2314 and tell us what you’re running; we’ll tell you straight what we can do and what it costs before anyone shows up.
Common HVAC Cleaning Problems We See in Woburn Homes
- Undersized trunk lines in 1950s capes. The original ductwork was sized for a furnace, not for central AC. When AC was added later, the same undersized trunk now has to move cold, dense air uphill to second-floor registers, and every bit of dust and restriction makes that worse.
- Collapsed flex runs behind finished basements. We see this constantly in Woburn’s colonials where someone finished the basement twenty years ago and sealed the ductwork behind sheetrock. The flex run sags or collapses, the second floor starves for air, and nobody knows until we put a camera in the duct.
- Returns pulling from wall cavities. On older retrofits, the return side often wasn’t ducted at all. It’s just a cavity between studs pulling air from wherever it can, and that air carries dust, insulation fibers, and whatever’s been living in the wall. Camera inspection shows this in minutes.
- Construction debris in the trunk from decades of renovations. Woburn homeowners renovate. Drywall dust, sawdust, screws, and bits of old lath end up in the return side during demo, and then the system blows that fine dust into every room every time the fan kicks on.
Pricing for HVAC Cleaning in Woburn, MA
A standard single-system HVAC cleaning in Woburn runs $385 – $685. If you add evaporator coil cleaning on its own, expect $180 – $320. If your system has multiple returns, a second air handler, or ductwork that requires significant disassembly to access, the price moves toward the top of that range, and we’ll show you exactly why before we start. What drives cost up in Woburn specifically is layout: finished basements that hide trunk lines, older sheet-metal ductwork that’s harder to access, and systems retrofitted across decades with odd branch configurations. We give you one written price per system before work begins. That price does not change at the door. Call (737) 727-2314 for a free estimate; you’ll get a real number, not a range designed to get a foot in the door.

FAQs About HVAC Cleaning in Woburn
We charge one flat price per system, never per vent. Per-vent pricing on Woburn’s older trunk-and-branch layouts is how homeowners get quoted a low teaser number that balloons once the tech counts every register, return, and branch run. Our written price covers the entire system: supply ducts, return ducts, air handler, blower, and evaporator coil. Call (737) 727-2314 and we’ll quote your whole system for one price before any work starts.
Every 3 to 5 years for most Woburn homes, and sooner if you’ve done renovations, have pets that shed heavily, or live near a busy road where fine dust comes through open windows and settles into the returns. If your system is less than three years old, you don’t have allergies or respiratory issues, and no one’s remodeled recently, you can typically wait. We’ll tell you straight if a cleaning would help or if you’re better off spending money elsewhere. That’s part of how we operate, and it’s why homeowners around Shaker Glen and off Washington Street keep calling us back.
We start with a camera inspection of the trunk lines and branch runs to see what’s actually in your ducts and whether any flex has collapsed or disconnected. Then we set negative pressure with Abatement Technologies HEPA filtration so nothing escapes into your living space, run agitation tools through every supply and return, clean the air handler and blower motor, and finish with the evaporator coil. Before we pack up, you get before-and-after photos of your own ducts. Our crew was in the Reeves Elementary area off Washington Street on a 1950s cape where the second-floor registers barely moved air and the return pulled dust off the wall. Camera inspection showed a collapsed flex run and a buildup of lint and construction debris in the trunk; we set negative pressure, cleaned the supply and return ducts, cleaned the air handler and blower motor, and the homeowner had before-and-after photos of their own ducts before we left.
Yes. A full HVAC cleaning in Woburn includes the supply and return ducts, trunk lines, air handler, blower motor, and evaporator coil. We don’t sell a duct cleaning that skips the coil, because the coil is where airborne dust condenses and cakes up, and cleaning the ducts without it leaves the most important restriction in place. If your coil needs a standalone cleaning and the rest of the system is in good shape, we’ll quote that separately and tell you which approach makes sense for your money.
We don’t promise same-day service. Proper HVAC cleaning in Woburn takes time: camera inspection, negative-pressure setup, agitation, coil cleaning, and documentation. We schedule each job so the tech can do it right, not rush it to fit a same-day slot. That said, a live person answers our phone 24/7, so call (737) 727-2314 and we’ll get you on the calendar for the soonest available slot and give you a written price before we confirm the booking.
