AfterAir Duct Cleaning in Lexington, MA
Dryer vent cleaning in Lexington runs $149 to $289 for most single-family homes, depending on vent length and access. What changes the job here is the housing stock: mid-century Colonials and split-levels with original galvanized ductwork that has spent 50 to 70 years collecting whatever the forced-air system pushed through it. Lexington’s heating season runs from October through April, which means six to seven months of continuous air movement through ducts that were never designed for today’s high-efficiency air handlers. Call (806) 606-6902 for a written price before any work begins.
Why Lexington Homes Are Different
Lexington experienced its dominant residential build-out between 1955 and 1975, when the town’s Colonial Revival, split-level, and ranch-style homes were constructed with original galvanized sheet-metal ductwork. That ductwork is now 50 to 70 years old. Because Lexington property values are among the highest in Middlesex County, these homes are routinely gutted and renovated rather than torn down. Each renovation stirs decades of accumulated dust, fiberglass liner particulates, and construction debris directly into existing duct systems. The ducts were never designed for the modern high-efficiency air handlers now being retrofitted into them.
The town’s dense, mature tree canopy adds another layer. Heavy spring pollen loads overwhelm return-air filters and push particulates deep into duct interiors. Technicians working in neighborhoods like Hastings Square and East Lexington repeatedly encounter 1960s split-levels where a finished basement conversion or HVAC swap left an abandoned lateral duct branch sealed with tape that has since failed. That hidden dead leg feeds debris back into the main trunk every time the system runs. Near the Battle Green, a smaller share of homes predate 1900 and were retrofitted with forced-air systems in the postwar era, often with non-standard or undersized trunk lines that complicate Air Duct Cleaning in Lexington.
Our Main Lexington Services
Two jobs account for most of the calls we take from Lexington homeowners: full air duct cleaning and HVAC cleaning. Both involve the same mid-century ductwork challenges, but they follow different scopes.
Air Duct Cleaning in Lexington
Full air duct cleaning in Lexington addresses the entire duct system: supply runs, return runs, plenums, and registers. On a 1960s split-level in East Lexington, that often means navigating original branching runs hidden inside finished walls added during successive remodels. We photograph the inside of every duct run before and after, so you see exactly what was removed. The job is quoted with a written price before a panel comes off. Learn more about Air Duct Cleaning in Lexington.
HVAC Cleaning in Lexington
HVAC cleaning in Lexington focuses on the mechanical components: blower motor, evaporator coil, condensate pan, and the air handler cabinet. In Lexington’s October-through-April heating season, these components accumulate a fine film of dust that reduces airflow and forces the system to work harder. Cleaning them restores efficiency and reduces what gets pushed into the ducts afterward. We use equipment from Rotobrush and Honeywell for this work. See HVAC Cleaning in Lexington for full scope and pricing.

BeforeAfterDryer Vent Cleaning in Lexington
Dryer vent cleaning in Lexington typically runs $149 to $289 for a standard single-family home. The job matters more here than in milder climates because Lexington’s long heating season keeps dryers running heavily from October through April, which accelerates lint accumulation inside the vent run. In mid-century Colonials and split-levels around Hastings Square and East Lexington, dryer vents are often long, multi-elbow runs hidden inside finished walls, which trap lint faster than short, straight runs. Dryer Vent Cleaning is the single most effective step you can take to reduce dryer run times and fire risk.
Dryer Vent Inspection
Signs you need it
Clothes taking longer than 45 minutes to dry or a burning smell while the dryer runs.
What it costs in Lexington
A camera-based dryer vent inspection in Lexington runs $89 to $149 when done as part of a cleaning.
How we do it
We run a camera through the full vent run, measure total length, count elbows, and document every restriction with photographs.
Vent Cleaning
Signs you need it
The dryer runs hot, the outside vent flap barely moves, or you see lint building up around the exterior vent cap.
What it costs in Lexington
Full dryer vent cleaning in Lexington runs $149 to $289 depending on vent length and access.
How we do it
We use a Rotobrush rotary brush system with negative-pressure extraction to dislodge and remove compacted lint from the entire vent run, followed by a camera verification pass.
Lint Removal
Signs you need it
Visible lint at the exterior vent opening or a dryer that shuts off mid-cycle and restarts minutes later.
What it costs in Lexington
Targeted lint removal inside the vent run is included with full vent cleaning; as a standalone job it runs $99 to $169.
How we do it
We dislodge packed lint from elbows and straight sections using air whips and rotary brushes sized to your specific vent diameter.
Bird Guard Installation
Signs you need it
Nesting material visible at the exterior vent cap or chirping sounds near the vent opening.
What it costs in Lexington
Bird guard installation in Lexington adds $49 to $89 to a vent cleaning visit, including the guard itself.
How we do it
We install a stainless steel Guardsman bird guard over the exterior vent cap, sized to your existing vent opening, after removing any nesting material.
What Dryer Vent Cleaning Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Dryer Vent Inspection | $89 - $149 |
| Full Vent Cleaning | $149 - $289 |
| Bird Guard Installation | $49 - $89 |
How often should a dryer vent be cleaned in Lexington?
Every 12 to 18 months for most Lexington households. Homes with long vent runs inside finished walls, multiple elbows, or heavy winter dryer use may need annual service. Your written quote includes our recommendation based on what the camera shows. Call (806) 606-6902 to schedule.
Will dryer vent cleaning make my dryer last longer?
A restricted vent forces the dryer’s blower to work harder, which shortens motor life and overheats the heating element. Removing the restriction reduces runtime and heat stress. Call (806) 606-6902 for a written price.
Duct Repair & Sealing in Lexington
Duct repair and sealing in Lexington addresses the leaks, failed tape joints, and abandoned branches that bleed conditioned air into wall cavities and crawl spaces. A typical mid-century home here loses 20 to 30 percent of its heated air through duct leaks before it ever reaches a register. Duct Repair & Sealing restores that loss by finding and closing every leak path in the system.
Duct Sealing
Signs you need it
Some rooms never reach temperature, heating bills climb each winter, or dust re-appears within days of cleaning.
What it costs in Lexington
Whole-system duct sealing in Lexington typically runs $450 to $1,100 depending on the number of accessible joints and the size of the home.
How we do it
We locate leaks with a pressure test, then seal every accessible joint, seam, and plenum connection with fiber-reinforced mastic applied to code.
Flex Duct Repair
Signs you need it
A flex duct is kinked, crushed, or separated at a connection, causing low airflow to one room or one floor.
What it costs in Lexington
Flex duct repair or replacement in Lexington runs $150 to $400 per section depending on diameter and run length.
How we do it
We remove the failed section, size the replacement to your system’s airflow requirements, and connect it with mastic-sealed metal collars.
Duct Insulation
Signs you need it
Ducts running through unconditioned spaces like attics or exterior-wall chases sweat in summer or lose heat in winter.
What it costs in Lexington
Duct insulation in crawl spaces and attics in Lexington runs $300 to $800 for a typical five-to-eight-run system.
How we do it
We wrap exposed duct runs with fiberglass insulation and seal the vapor barrier with tape, then photograph the completed work.
What Duct Repair & Sealing Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Whole-System Duct Sealing | $450 - $1,100 |
| Flex Duct Repair (per section) | $150 - $400 |
| Duct Insulation | $300 - $800 |
How do I know if my Lexington ducts are leaking?
A pressure test quantifies the leak rate in CFM, and our camera work shows exactly where the leaks are. You get that documentation as part of the job. Call (806) 606-6902 for a written quote.
Can you repair the abandoned duct branches common in Lexington split-levels?
Yes. We locate dead legs with camera inspection, then seal them at the trunk with metal caps and mastic so they cannot feed debris back into the system. Call (806) 606-6902 to discuss your system.
Air Quality & Sanitizing in Lexington
Air quality and sanitizing in Lexington targets the biological debris and particulate buildup that accumulates inside ducts during the town’s long heating season. In homes with original galvanized ductwork, decades of dust, fiberglass liner particulates, and renovation debris create an environment where mold and bacteria can establish themselves. The same mature tree canopy that pushes heavy spring pollen into Lexington return-air systems also carries organic matter that sustains biological growth inside the duct interior. Air Quality & Sanitizing addresses that layer after the mechanical cleaning is done.
Mold Treatment
Signs you need it
You can see mold on register grilles, smell mustiness only when the system runs, or the camera shows growth inside the ductwork.
What it costs in Lexington
Mold treatment for a typical Lexington duct system runs $500 to $1,400, with the final number set by the affected surface area.
How we do it
We apply an EPA-registered antimicrobial treatment to affected surfaces using Abatement Technologies fogging equipment, then document the post-treatment condition with photographs.
Bacteria Sanitizing
Signs you need it
A persistent odor that cleaning alone did not remove, or a household member with ongoing respiratory irritation when the heat or AC runs.
What it costs in Lexington
Full-duct bacteria sanitizing in Lexington runs $350 to $800 including the inside of supply and return runs.
How we do it
We fog the entire duct network with a sanitizing agent, dwell-tested to manufacturer specification, then run a fresh-air purge before handing the system back.
UV Light Installation
Signs you need it
Recurring mold or bacterial growth at the evaporator coil, especially in newer high-efficiency air handlers that retain more coil moisture.
What it costs in Lexington
A coil-mounted UV light installation in Lexington runs $650 to $1,100 including labor and the lamp itself.
How we do it
We install a Honeywell UV lamp focused on the evaporator coil, wired to run continuously, and verify lamp output with a UV meter.
What Air Quality & Sanitizing Costs in Lexington
| Item | Typical range in Lexington |
|---|---|
| Mold Treatment | $500 - $1,400 |
| Bacteria Sanitizing | $350 - $800 |
| UV Light Installation | $650 - $1,100 |
Does sanitizing replace duct cleaning in Lexington?
No. Sanitizing is a follow-up to cleaning. You cannot sanitize what is still buried under debris. We clean first, photograph the result, then apply the treatment. Call (806) 606-6902 for a written price.
Will air quality treatment help with Lexington’s spring pollen season?
Combined with sealing duct leaks and keeping a clean return-air filter in place, sanitizing and cleaning reduce the particulate load that Lexington’s mature tree canopy pushes into your system each spring. Call (806) 606-6902 to discuss your home.
