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, CA | Hollis Air Duct Cleaning
Air Duct Cleaning in Boston for Lennox systems typically runs $450 – $900 for a full system, depending on how many returns and the condition of the flex duct. We’re Hollis Air Duct Cleaning, and we’ve worked on Lennox systems inside Boston’s triple-deckers since 2004. The thing that makes our Lennox work different here comes down to one fact: older Boston homes weren’t built for central air, so the ductwork is almost always a retrofit, which means leaks, crushed runs, and shared returns between units. Call (361) 326-5060 for a written estimate before any work starts.
Why Boston Residents Choose Us for Lennox Service
We know how a Lennox EL296V behaves when it’s fed by flex duct snaked through a closet chase in Dorchester or a rowhouse in South Boston, and our Boston Dryer Vent Cleaning team understands the same tight spaces. That’s not knowledge you get from a manual. Roy Castellanos, our owner, learned the mechanical trades through the sheet metal and air conditioning program at Los Angeles Trade-Technical College and spent years doing hands-on duct work before starting Hollis. He’s the one who sets the standard our techs follow: price it in writing, do it by the book, leave the site clean.
We’re an independent Lennox service provider. Not authorized, not affiliated, just experienced. For critical components like blower motors and control boards, we use OEM Lennox parts. For wear items like flex duct and mastic, we use aftermarket equivalents that meet or exceed spec. That stance keeps your costs honest without cutting corners on what matters. Our techs arrive background-checked and uniformed, and every job carries the 365-Day Done Right Promise in writing. If it fails within a year, we return and make it right, no charge.

Common Lennox Air Duct Cleaning Problems We Solve in Boston
- Crushed flex duct in closet chases. Boston triple-deckers often route flex duct through narrow chases built into plaster walls. Over time, that duct kinks or collapses, especially behind a Lennox EL296V furnace jammed into a hallway closet. The result is reduced airflow and rooms that never quite reach temperature. We replace the crushed run and clean the rest during the same visit.
- Musty odors from evaporator coil fouling. Humid Boston summers push condensation across Lennox air handler coils for months at a stretch. That moisture traps dust and organic matter, which turns into exactly the smell you’re noticing when the AC first kicks on. We clean the coil and the surrounding plenum, not just the ducts.
- Rusted condensate drain pans. Freeze-thaw cycles and coastal humidity are brutal on older Lennox furnaces in Boston basements. A rusted drain pan leaks onto the floor or into the blower cabinet. We flag it during cleaning and can replace it, usually with the part on hand.
- Shared return cross-contamination between units. This is the Boston-specific one. In triple-deckers, Lennox systems often pull return air through a common chase serving multiple units. One neighbor’s cooking odors, pet dander, or cigarette smoke migrates into your unit. We seal and reroute returns to stop it.
- Undersized, leaky ductwork in pre-war buildings. Homes built between 1880 and 1930 weren’t built for forced air. The retrofit ductwork is frequently undersized and leaking at the joints. We use duct sealing mastic, not tape, because mastic actually holds in a Boston freeze-thaw cycle.
Lennox Service in Boston: What Local Conditions Mean for Your Equipment
Here’s what you won’t read on a generic Lennox page. Boston’s triple-deckers frequently share return ducts between units, which means one neighbor’s cigarette smoke, fried food, or cat dander enters your apartment through your own Lennox system’s return path. You can’t clean your way out of that problem with a rotary brush alone, because the issue is the return plumbing itself. We’ve seen it on Pleasant Street in Dorchester, where a third-floor tenant smelled the second floor’s Pall Malls every time the blower kicked on. The fix was sealing the shared trunk joint with mastic and rerouting the return to a dedicated chase. If you’re in a triple-decker and you smell things you didn’t cook, the ductwork is the messenger. We trace it with a video inspection and seal it at the source. That’s the difference between cleaning ducts and fixing a system, and in Boston, you usually need both.
Lennox Models & Products We Service in Boston
We service the full Lennox lineup you’re likely to find in Boston homes. The Elite Series (EL296V, EL296UH) shows up in plenty of mid-range retrofits. The Merit Series (ML180, ML193) is common in budget-conscious triple-decker flips. The Dave Lennox Signature Collection (SL280V, SLP98V) sits in the high-end rowhouse conversions. We also still work on legacy Lennox Complete Heat units, which appear in older Boston buildings that haven’t seen a major HVAC overhaul since the 1990s.
For critical components, we use OEM Lennox parts. For flex duct, mastic, vent caps, and similar wear items, we use high-quality aftermarket equivalents. We stock enough locally that most Boston jobs don’t wait on a parts shipment.
Lennox Service Pricing in Boston
Expect $450 – $900 for a full Lennox duct cleaning in Boston, depending on system size, number of returns, and how much flex duct needs replacing.

FAQs – Lennox Air Duct Cleaning in Boston
Yes. We replace crushed or kinked flex runs as part of the cleaning visit. The replacement duct is on the truck, so we don’t need a second appointment. Call (361) 326-5060 and we’ll include the replacement in your written estimate.
Almost certainly, especially in a Boston triple-decker. Shared returns between units pull air from neighboring apartments into your Lennox system and push it through your registers. We trace the return path with a video camera, find the failed joint, and seal it with mastic. When the return can’t be salvaged, we reroute it to a dedicated chase.
Every 3 to 5 years for most Boston homes, more frequently if you’re in a triple-decker with shared returns or you’ve done a renovation that kicked drywall dust and plaster into the system. Boston’s humid summers and long heating seasons mean your Lennox system runs hard in both directions, accumulating more material than a system in a milder climate.
For critical components like blower motors, control boards, and heat exchangers, yes. For wear items like flex duct, mastic, and vent caps, we use aftermarket parts that meet or exceed OEM specs. That keeps the bill honest without compromising the repair. Call (361) 326-5060 for a written price on any repair we flag during cleaning.
That depends on what the video inspection shows. If the heat exchanger is rusted through or the blower motor is on its last legs, cleaning the ducts is putting a fresh coat of paint on a failing system. We’ll give you a straight repair-vs-replace assessment based on what we find, not what we want to sell. The estimate is free, and it’s in writing. Call (361) 326-5060.
