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.

AfterLennox Air Duct Cleaning in Boston, NY | CleanRun Air Duct Cleaning
We provide independent Lennox Air Duct Cleaning - Boston, and the work here looks different than it does anywhere else. Lennox systems in this city are usually retrofitted into triple-deckers and rowhouses built decades before forced air existed, which means the ductwork runs through spaces never designed for it. That changes how debris accumulates, how mold forms, and what a proper cleaning actually requires. Call (806) 606-6902 and we’ll show you what’s inside your ducts before we touch anything.
CleanRun Air Duct Cleaning has worked on Lennox forced-air systems in Boston’s retrofit-heavy housing stock since 2013. We’re an independent Lennox service provider, not manufacturer-affiliated or authorized, which matters in one specific way: we’ll tell you what the camera finds, recommend what actually needs doing, and hand you a written price before a single panel comes off. No exceptions. Our techs know Lennox Elite, Merit, and Signature Collection systems inside out, and they know how those systems fail in Dorchester, Roxbury, Jamaica Plain, and the South End specifically. That combination is why Boston homeowners call us.
Why Boston Residents Choose Us for Lennox Service
Lennox equipment is well built, but it gets installed into some truly unforgiving spaces in this city. Triple-deckers in Dorchester and Roxbury, brick rowhouses in the South End and Back Bay, mid-century ranches in West Roxbury and Hyde Park. Each building type puts different stress on a Lennox system, and our crews see all of it on a weekly basis. Tomas Reyes, our owner and lead technician, grew up in a building where the ductwork hadn’t been touched since the Carter administration, and he’s built CleanRun around a simple principle: camera inspection first, written scope second, no work starts until you’ve seen exactly what’s inside your ducts.
We carry OEM Lennox parts for warranty-year systems and critical components like blower motors and control boards. For duct sealing, insulation, and flex duct replacement, we use high-quality aftermarket materials that outperform the aging fiberglass liner and fittings originally installed in so many Boston homes. Every job ends with a documented photo record of every duct run, inside, before and after. That’s not a marketing promise. It’s a standard deliverable we’ve produced on every job since 2013.
Common Lennox Air Duct Cleaning Problems We Solve in Boston
- Mold on Lennox evaporator coils in basement air handlers. Boston’s coastal humidity means repeated condensation cycles inside ductwork, especially in basement air handlers common to triple-deckers. Lennox coils develop surface mold during the shoulder seasons, and that mold sheds spores into supply ducts throughout the spring and fall. We clean the coil, treat the plenum, and document the before and after.
- Flex duct sagging and separating in retrofitted closets and stairwell chases. Lennox air handlers in older Boston buildings often feed into flex duct routed through spaces never meant for mechanicals. That duct sags, pulls apart at joints, and draws in debris from shared plumbing and electrical cavities. We repair or replace the flex, reseal joints with mastic, and reroute sections when the original path is hopeless.
- Aging fiberglass duct liner shedding particulate onto Lennox blower wheels. Pre-WWII rowhouses in the South End and Back Bay frequently have original fiberglass duct liner that’s deteriorating. That liner sheds fine particulate that accumulates on blower wheels, reduces airflow, and drives up energy use on Lennox systems. We remove deteriorated liner where accessible and seal what remains.
- Dust and grease contamination on Lennox variable-speed blower motors. Long Boston heating seasons, October through late April, push more air through the system than anywhere inland. Control boards and blower assemblies collect a hard, greasy dust that causes intermittent operation by spring. We clean the blower assembly and verify operation before we leave.
- Kitchen grease vapor migrating into Lennox ducts through shared chases. This one is uniquely Boston. In triple-deckers, flex ducts often share vertical chases with kitchen exhaust flues from the units below. Grease vapor drifts upward, coats the inside of ductwork, and bakes on during heating season. A shop-vac cleaning won’t touch it. We use negative-pressure extraction with agitation tools designed for exactly this contamination load.
BeforeAfterLennox Service in Boston: What Local Conditions Mean for Your Equipment
Here’s the thing about Boston that doesn’t show up in a Lennox manual. In triple-deckers throughout Dorchester and Roxbury, Lennox systems are routinely fed by flex duct routed through vertical chases shared with kitchen exhaust flues. The unit below cooks, grease vapor rises through the shared chase, and it coats the inside of the flex duct and the Lennox evaporator coil. Then heating season starts and that greasy film bakes on. You won’t find this contamination pattern in the single-family forced-air stock of neighboring Brookline or Newton. Their ducts were built as ducts. Boston’s were improvised decades later through stairwell chases, closets, and floor cavities, and those improvised runs accumulate debris faster and attract contamination loads unlike anything in purpose-built suburban housing. That’s why our Boston crews carry different agitation tools, different coil cleaning procedures, and a different set of expectations than a crew working a standard ranch house. The photo tells you what’s in there. Everything else is just paperwork.
Lennox Models & Products We Service in Boston
We work on the full Lennox residential range you’ll find in Boston homes. That means the Elite Series, including the EL296V variable-speed gas furnace and the EL16XC1 air conditioner. The Merit Series, like the ML180 furnace and 13ACX condenser, shows up constantly in rental units and owner-occupied triple-deckers. And the Dave Lennox Signature Collection, including the SLP99V modulating furnace, sits in a lot of the newer high-end gut renovations in the South End and Back Bay. For warranty-year systems, we use OEM Lennox parts for critical components. For duct sealing and flex replacement, we stock aftermarket materials locally that outperform the original aging liner and fittings. If a blower or evaporator coil is heavily contaminated or failing, we’ll give you a straight repair-versus-replace estimate, not a clean-only upsell.
Lennox Service Pricing in Boston
Air duct cleaning for a Lennox system in Boston typically runs $450 to $900 for a full single-system job, depending on the number of duct runs, the type of contamination, and whether flex duct repair or coil cleaning is needed. Multi-unit triple-decker work, where shared chases complicate access, lands at the higher end or slightly above. Evaporator coil cleaning adds $150 to $400. Duct sealing runs $600 to $1,500 depending on system size. Flex duct repair or replacement is $250 to $800 per section. Every estimate is written, itemized, and delivered before any work starts under Haven Standard Clause 1. Call (806) 606-6902 and we’ll put a number in writing. Estimates are free.

FAQs - Lennox Air Duct Cleaning in Boston
Boston’s coastal position on Massachusetts Bay means Atlantic humidity settles into basements and air handlers during spring and fall, and Lennox evaporator coils in those basement installations cycle through repeated condensation. That moisture, combined with organic debris already inside the ducts, creates surface mold that sheds spores into your supply air. A proper Boston HVAC Cleaning removes the mold and the debris feeding it, and sealing the flex duct joints reduces what re-enters. Call (806) 606-6902 for an exact quote, free.
Yes, in most cases. We use negative-pressure extraction with rotary agitation tools sized for the narrow flex runs typical in Boston triple-deckers, and we access the ducts through the registers and air handler, not by cutting into walls or ceilings. If a section of flex has separated or collapsed, we’ll show you the camera footage and give you a written price for replacement before any work starts. Call (806) 606-6902 to schedule an inspection.
Every 3 to 5 years for a rowhouse in the South End or Back Bay, and more often if you have pets, if you cook heavily, or if you’ve done renovation work that generated drywall dust. The retrofit ductwork in those buildings was never designed for forced air, so it accumulates debris faster than a suburban system. If you’re noticing dust on surfaces within days of cleaning, that’s a sign the ducts are overdue. Call (806) 606-6902 and we’ll inspect.
Yes. A blower wheel caked with dust and debris moves less air for the same electricity, which means the furnace runs longer to hit the thermostat setpoint. Cleaning the blower wheel and the blower housing restores designed airflow, which shows up as lower energy use over the Boston heating season. We’ll photograph the blower before and after so you can see exactly what was removed. Call (806) 606-6902 for a written estimate.
Usually yes, but it depends on where the grease is. If kitchen vapor from a unit below has migrated through a shared chase and coated the coil or the flex duct lining, a standard cleaning won’t remove it. We use degreasing agents rated for HVAC surfaces and coil-specific cleaning procedures, then seal the duct joints to reduce future migration. The smell goes away when the source is removed. Call (806) 606-6902 for an inspection and a written quote, free.
