Air Duct Cleaning in Lexington - One Flat Price, Before-and-After Photos

Fast, Reliable Air Duct Cleaning Across Lexington

Air duct cleaning in Lexington typically costs between $450 and $900 for a full system on a mid-century home, and most jobs are completed in a single visit. We treat Lexington’s 1955-1975 housing stock differently than newer construction because the original ductwork demands a different inspection protocol. If you’re seeing dust settle on furniture within days of cleaning, or a register is blowing visible particles, the issue usually sits deeper in the branching runs than a standard vacuum pass can reach.

Why CleanRun Air Duct Cleaning Is Lexington’s Preferred Air Duct Cleaning Company

Lexington homeowners tend to research before they call. They want to know what’s actually inside their ducts, what it costs in writing, and what proof they’ll have when the crew leaves. That’s the conversation we’re set up to have.

Tomas Reyes, who runs our operations, has made a point of this since 2013: every job in Lexington gets a documented before-and-after photo record of each duct run, and every price is delivered in writing before work begins under Haven Standard Clause 1. No “call for a quote” games. We photograph the plenum, the main trunk, and the branch runs with a camera that shows exactly what’s there, whether it’s three inches of construction debris at the first elbow or a dead-leg branch that’s been quietly filling with sawdust since a basement remodel.

Our crews serve Lexington from the Boston office, but the technicians you’ll see at your door are background-checked, uniformed, and named before they arrive. The equipment list includes Rotobrush and Nikro agitation tools paired with HEPA-filtered negative-pressure extraction, not a shop vac bolted to a van. When we finish, you receive the photo record and the written warranty as standard deliverables, not add-ons.

Lexington’s Mid-Century Ductwork Problem

Lexington experienced its dominant residential build-out between 1955 and 1975, when Colonial Revival, split-level, and ranch homes went up with original galvanized sheet-metal ductwork. That ductwork is now 50 to 70 years old. It has never been fully replaced because Lexington property values make renovation far more common than teardown, and each renovation shakes decades of accumulated dust, fiberglass liner particulates, and construction debris directly into the existing duct system.

Here’s what this means in practical terms. A gut remodel on a 1963 split-level in East Lexington doesn’t just create drywall dust. It sends fine gypsum powder into returns that were never sealed for this kind of load. The original duct runs were designed for gravity-era heating assumptions and undersized by modern standards, so they’ve never handled the airflow of today’s high-efficiency air handlers well. That’s the specific combination we see repeatedly: mid-century ducts, renovation debris, and a modern blower pushing it all through the house.

Video Inspection is the first step on nearly every Lexington job. Before we quote a full cleaning, we run a camera through the main trunk and branch runs. This tells us whether we’re dealing with normal dust accumulation or something structural like a failed dead-leg branch or a disconnected return. Lexington’s split-levels are especially prone to abandoned lateral branches. A finished basement conversion or HVAC swap leaves a stub of duct sealed with tape, and when that tape fails over years of thermal cycling, the dead leg becomes a hidden pocket that collects debris and then dumps it back into the main trunk every time the blower cycles.

We cleaned a 1963 split-level in East Lexington where exactly this had happened. The camera found a dead-end branch packed with sawdust and old fiberglass liner that was feeding directly back into the trunk on every blower cycle. After source removal with HEPA-filtered negative pressure and agitation, the return-air register stopped blowing visible dust onto the first floor. The homeowner kept before-and-after photos from our camera feed as part of the job record.

Heavy Pollen and Long Heating Seasons in Lexington

Lexington’s climate does two things that accelerate duct contamination. The cold winters drive forced-air heating from October through April, which means seven months of continuous particulate circulation. The town’s mature tree canopy then drops a heavy spring pollen load onto every return filter, and once that filter saturates, the pollen passes through and deposits deep inside the branch runs.

This isn’t a cosmetic issue. Pollen caked inside duct interiors becomes a food source for dust mites and a trigger for allergy symptoms that persist even after the outdoor bloom ends. The warm air from the furnace then re-suspends those particles into living spaces in a cycle that a standard filter replacement won’t break. A full duct cleaning removes the source, not just the symptom.

Our Air Duct Cleaning Services in Lexington

Residential Duct Cleaning

For Lexington’s mid-century Colonials, split-levels, and ranches, we clean the full system: supply ducts, return ducts, main trunk, and plenum. Each run gets a camera pass first, then mechanical agitation to dislodge caked-on dust and debris, then HEPA-filtered negative-pressure extraction to pull it out. A typical Lexington home with original galvanized ductwork takes a full day because the branch runs were often sealed into finished walls during successive remodels and require more careful access than newer rectangular duct.

Commercial Duct Cleaning

Lexington’s commercial spaces, from offices near the Battle Green to retail and medical suites along Massachusetts Avenue, need a different scheduling reality. We work around occupied hours, clean in phases so one zone stays operational, and document every run for compliance and maintenance records. Commercial systems in Lexington are frequently retrofitted into older buildings that predate modern HVAC standards, which means undersized trunks and flexible branch lines that collect debris faster than they should.

Supply Duct Cleaning

Supply ducts are the pressurized side of the system, the runs that deliver conditioned air to each room. In Lexington homes with original galvanized sheet metal, these are the runs most likely to have accumulated a crust of dust and fiberglass liner particles over 60 years. We clean each supply run individually, never just the main trunk, and the before-and-after camera feed shows the interior of every branch run you can’t see from a register.

Return Duct Cleaning

Return ducts pull air back to the furnace, which means they see everything that settles in your home: carpet fibers, pet dander, renovation dust, and the fine road dust that drifts in from Lexington’s residual unpaved roads near conservation land and open space. We see return ducts with a quarter inch of compacted gray material that never moves unless mechanically dislodged. Cleaning returns is not optional on a full system job; it’s where the accumulated load actually sits.

Full System Cleaning

A full system cleaning in Lexington covers the supply and return runs, the main trunk, the plenum, and the air handler cabinet. Depending on what the camera finds, we may also sanitize with a mechanically applied treatment designed for porous duct surfaces. The point is that a partial pass doesn’t solve the problem in mid-century systems; the whole network has to be treated as one connected system.

Trusted Brands We Service in Lexington

Most Lexington homes have one of a handful of common furnace and air handler configurations, and we service all of them. The equipment we use on the cleaning side includes Rotobrush and Nikro agitation and extraction systems, paired with HEPA filtration. For homes with Aprilaire or Honeywell filtration installed on the return side, we inspect the filter housing and blower cabinet during the same visit, because a high-efficiency filter can’t do its job if the ducts upstream and downstream of it are carrying decades of accumulated dust. We carry Guardsman sanitizing treatment for systems that show biological growth on the camera feed.

Common Air Duct Cleaning Problems We See in Lexington Homes

• Renovation dust pulled into returns after gut remodels. Lexington’s mid-century homes get renovated rather than torn down, and fine gypsum and fiberglass particles get pulled into return ducts during demolition and finish work. This material stays in the system and re-circulates for months unless mechanically removed.
• Dead-leg branches left from HVAC swaps or finished basements. A 1960s split-level in Lexington that had a basement finished in the 1980s often has a sealed-off duct stub somewhere in the system. When the tape or cap fails, it becomes a debris accumulator that spills back into the trunk on every blower cycle.
• Spring pollen loading from the mature tree canopy. Lexington’s dense tree cover pushes heavy pollen loads into return filters every spring, and once the filter saturates, the pollen migrates into branch runs. This leads to premature blower motor wear because the motor works against a partially restricted system.
• Fiberglass liner degradation in original galvanized ducts. Many 1955-1975 ducts in Lexington were lined with fiberglass that has since begun to shed. The camera typically shows a fine white or gray particulate trail along the bottom of the run, and that material ends up in the air stream either through normal airflow or when renovations disturb the ducts.
