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.
Fast, Reliable Air Duct Cleaning Across Lexington
Air duct cleaning in Lexington, MA typically costs $450-$850 for a complete residential system and takes three to five hours for a thorough job on a mid-century home. Most Lexington appointments are scheduled within one to two weeks, with dispatch coordinated from our Boston office and crews arriving fully equipped for the town’s specific housing stock. Call (323) 918-4345 for a free written estimate before any work begins.
We’ve been driving the same Lexington streets since 2005, and we know the difference between a ranch on Waltham Street and a split-level off Marrett Road. That matters because the duct systems are different, the failure modes are different, and the fix is different. Our technicians arrive with Rotobrush agitation tools and Nikro HEPA collection systems sized for the pressed-fiberglass plenums and trunk-and-branch layouts common to homes built here during the Route 128 boom. We’re not guessing when we quote your job. We’ve already seen what your house is likely hiding.
Why Morton’s Air Duct Cleaning Is Lexington’s Preferred Air Duct Cleaning Company
Lexington homeowners call us back because we treat the house like it’s our own. That means shoe covers and drop cloths before we touch a floor, quiet tool settings during nap hours, and a written price you approve before we start the truck-mounted vacuum. Every visit is backed by our 365-Day Done Right Promise and the Cedarwell Care Promise, which includes a photo of the clean-up before we leave, so you see exactly what we found and what we fixed.
Our reputation in Lexington is built on specificity. We don’t offer a generic “whole house” price and then discover “unexpected” problems once we’re inside. We ask about your home’s age, renovation history, and whether you’ve noticed temperature imbalances between floors, because those details tell us whether we’re looking at a standard source-removal clean or a system with disconnected crawl-space runs and degrading fiberglass components. Paul Adeyemi and our team have trained our Lexington crews to recognize the town’s mid-century housing patterns and quote accordingly.
Calls are answered by a live person, 24/7, not a voicemail tree. Scheduling to Lexington runs from our Boston office, with crews carrying the full inventory of sheet-metal fittings and sealed plenum materials needed for the repairs we commonly find in 1950s-1970s homes here.
Vent Cleaning in Lexington
Vent cleaning in Lexington addresses the visible endpoint of your duct system, but in many of this town’s mid-century homes, the registers are the least interesting part of the job. A proper vent cleaning removes the accumulated dust, pet hair, and cooking grease that collects at the supply and return grilles, then extends into the boot and first few feet of branch line. In Lexington’s ranch and split-level homes, we typically find vent cleaning necessary every three to five years for households with kids and pets, or sooner after renovations. A standard vent cleaning for a Lexington home runs $180-$340 for supply registers only, or $320-$480 when combined with return vent cleaning and basic trunk-line access.
Supply Vent Cleaning
Supply vents push conditioned air into your rooms, and in Lexington’s older forced-air systems, they’re often the first place you’ll notice fiberglass particulate or black debris collecting on the grille fins. We remove each register, clean the boot with Rotobrush agitation, and HEPA-vacuum the visible branch line. If the boot is connected to a fiberglass duct board plenum, we flag it for you, because cleaning the vent without addressing the plenum is temporary.
Return Vent and Filter Housing Cleaning
Return vents pull air back to the air handler, and in Lexington homes with central hallway returns, these openings collect the most debris. We clean the grille, the filter housing, and the return trunk access point, checking for crushed ductwork or renovation debris that commonly blocks airflow in homes where walls were opened up for kitchen or bath expansions.
Air Duct Repair in Lexington
Air Duct Repair in Lexington is where our visits often end up, because cleaning alone doesn’t fix disconnected branches, crushed returns, or degrading fiberglass duct board plenums that are shedding material into your air stream. We find that roughly half the Lexington homes we inspect need some form of repair beyond source removal, and we quote that work upfront, never as a mid-job surprise. Typical air duct repair in Lexington ranges from $280-$550 for branch reconnection and sealing to $800-$1,400 for full plenum replacement with sealed sheet metal. The investment is specific to what we find, and we show you the camera footage before you decide.
Branch Reconnection and Sealing
Split-level homes along Lexington’s hillier interior corridors frequently route supply ducts through unconditioned crawl spaces beneath upper half-levels. We’ve found disconnected branches at the boot in these homes more times than we can count. The fix is straightforward: reconnect, support properly, and seal with mastic. But you need a crew that recognizes the symptom, typically a cold upper floor or weak airflow to specific rooms.
Fiberglass Duct Board Plenum Replacement
The pressed-fiberglass plenums installed in Lexington’s 1950s-1970s homes were never designed to last fifty-plus years. When they degrade, they don’t just leak, they shed fibers. We replace these with sealed sheet-metal plenums, fabricated to fit your existing air handler, and we insulate externally where needed. It’s a permanent fix for a material that was always going to fail with age.
Trusted Brands We Service in Lexington
Our Lexington crews work with professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, because entry-level rental gear doesn’t handle the dense accumulation in decades-old duct systems. Rotobrush brushes and whips agitate debris from fiberglass-lined trunk lines without damaging the substrate. Nikro HEPA-filtered negative-air machines maintain containment during the most disturbed phases of cleaning. For homes with Aprilaire or Honeywell media filters already installed, we stock replacement cartridges and can integrate upgraded filtration during the same visit. We don’t believe in selling you equipment you don’t need, and we don’t show up with tools too small for the job.
Common Air Duct Cleaning Problems We See in Lexington Homes
- Degrading fiberglass duct board plenums. The pressed-fiberglass supply boxes and plenums in Lexington’s mid-century homes are now 50-70 years old. They shed particulate into the airstream continuously, and a registers-only clean never touches the actual contamination source.
- Disconnected or crushed branch lines in split-level crawl spaces. Homes off Marrett Road, Bedford Street, and Waltham Street corridors frequently route supply ducts through unconditioned crawl spaces where low clearance, moisture, and renovation activity have damaged the runs. The symptoms show up as cold rooms or weak airflow, but the cause is hidden.
- Renovation debris in original trunk systems. Lexington’s high renovation rate means drywall dust, insulation fragments, and construction debris regularly enter existing ductwork during gut projects. Standard negative-pressure cleaning without mechanical agitation leaves this settled debris behind.
- Condensation and biological growth in unconditioned duct sections. Lexington’s humid summers create moisture accumulation inside ducts that pass through attics or crawl spaces, particularly in split-level homes where temperature differentials are extreme. We find this during camera inspection and address it with source removal and improved sealing.

FAQs About Air Duct Cleaning in Lexington
Lexington split-levels frequently route supply ducts through unconditioned crawl spaces beneath upper half-levels, where low clearance and temperature differentials create moisture accumulation, biological growth, and physical damage invisible from the registers. A standard registers-only clean never reaches these failure points. We use camera inspection to document the condition of these hidden runs and quote repair work upfront if needed. Call (323) 918-4345 to schedule an inspection.
Fiberglass duct board is a pressed-fiberglass material used for plenums and supply boxes in homes built from the 1950s through the 1970s, which describes much of Lexington’s housing stock. After 50-70 years of thermal cycling and airflow, this material degrades and sheds fibers into your airstream. Cleaning the visible ductwork without addressing a failing fiberglass plenum leaves the primary contamination source intact. We replace degrading fiberglass components with sealed sheet metal as part of our repair services.
Yes, our source-removal methodology adheres to NADCA guidelines for mechanical agitation, negative-air containment, and HEPA filtration. For Lexington’s older homes, we exceed the minimum where the standard doesn’t address specific failure modes like degrading fiberglass plenums or renovation debris requiring additional agitation passes. Our equipment from Rotobrush and Nikro is sized and maintained to deliver the airflow and filtration these standards require.
Yes, and significantly. Lexington’s renovation rate is high, and gut projects routinely introduce drywall dust, insulation fragments, and construction debris into existing trunk-and-branch systems. We find this even in homes where contractors attempted protection. A post-renovation clean requires mechanical agitation beyond standard negative-pressure pull, and we always inspect for crushed or disconnected runs where walls were opened. Schedule a post-renovation inspection to assess what actually entered your system.
For a typical Lexington household with kids and pets, every three to five years is appropriate. Homes with recent renovations, visible debris at registers, or occupants with respiratory sensitivities may need more frequent service. The 50-70 year old duct systems common in this town also mean that “cleaning” sometimes reveals repair needs that should be addressed regardless of schedule. We don’t push unnecessary visits, we’ll tell you honestly if your system looks fine. Call (323) 918-4345 and we can discuss your specific situation.
