In Boston, a typical air-duct cleaning job runs between $225 and $550. The single biggest price driver is the total length of ductwork plus how much buildup we find inside—more than any single room count or square footage. Because every home’s system is different, we always provide a free, written on-site estimate so you know the exact scope and price before we start.
What exactly are we cleaning—and why does it matter in Boston?
Your ductwork is the circulatory system of your home: supply and return ducts, trunk lines, branch runs, registers, and the blower/furnace compartment. Over time, Boston’s damp winters and summer pollen load these passages with dust, mold spores, rodent dander, and even fine soot from older oil-heating systems. Cleaning removes that debris, lowers indoor-particle counts, and helps your HVAC work safely and efficiently. Think of it as a lung flush for your house. Learn what’s inside your ducts and how often Boston homes need this service.
Three cost factors that change the bill in Boston homes
First is total lineal duct length—measured in feet, not rooms. A compact triple-decker in the North End with short trunk runs may run 150 ft, while a large Victorian in Back Bay can exceed 800 ft. Second is contamination level: a light film of household dust costs less to remove than heavy mold growth or decades of oil-soot accumulation common in pre-1980s Boston homes. Third is accessibility: vaulted ceilings, finished basements, or multi-story layouts require extra equipment or staging, adding labor. Boston’s historic housing stock often pushes labor higher than newer builds in the Seaport. See how we handle tricky Boston layouts.
Typical air-duct cleaning price ranges for Boston neighborhoods
Below are realistic ranges we see across Boston and nearby towns. Remember, these are starting points; a free on-site inspection is the only way to lock in your exact price. Request your written estimate before booking. For Cambridge, Brookline, and Somerville homes, expect similar ranges due to comparable housing stock and duct layouts.

A typical Boston single-family home (3 beds, 2,000–2,800 sq ft) with 300–500 ft of ductwork and moderate dust costs $225–$425. If your system has longer runs, vaulted ceilings, or finished basements, budget closer to $450–$550. We use negative-air machines, rotary brushes, and HEPA vacuums to capture debris without spreading it through your home. See our full service list.
Adding EPA-registered sanitizer to the blower compartment, coils, and ducts tacks on roughly $125–$225 depending on square footage. This step is especially valuable in older Boston homes where mold or musty odors linger after cleaning. We document spore counts before and after to prove the improvement. Learn why Boston homes need full sanitization.
Condo owners in Boston’s Back Bay or South End often share trunk lines. Cleaning just your branch run costs $150–$275. Whole-building common trunk cleaning starts around $400 and scales with floor count. We coordinate with condo boards to minimize disruption and provide a written scope for the association.

What a fair written estimate should include in Boston
A reputable Boston company will itemize: total lineal duct footage, number of supply/return runs, contamination level (light/moderate/heavy), sanitization add-ons, and any crawl-space or attic access fees. It should also list licensing numbers (Massachusetts requires a Home Improvement Contractor license), proof of liability insurance, and a start/end date. Avoid any bid that quotes by square footage alone—duct length is the real driver. Check our credentials.
Why the cheapest air-duct cleaning bid in Boston can be risky
Some Boston-area companies cut corners by skipping HEPA containment, using shop-vacs instead of negative-air machines, or outsourcing crews with minimal training. In older homes, improper agitation can dislodge mold spores into living spaces or even damage fragile ductboard. Worse, an unlicensed crew may miss carbon-monoxide hazards around the furnace. Always verify license status on the Massachusetts Office of Consumer Affairs site Massachusetts Home Improvement Contractor License Lookup. See how we protect your home.

Value add-ons and financing options for Boston homeowners
Beyond cleaning, consider adding dryer-vent service ($85–$150) to reduce lint fires, or coil cleaning ($95–$175) to restore cooling efficiency. We also offer flexible payment plans and accept most major credit cards to help spread the cost. Ask about seasonal discounts for spring or fall appointments when demand is lower. Explore all our services.
After the cleaning: keeping your Boston ducts cleaner longer
Replace HVAC filters every 60–90 days (MERV 8–11 for most Boston homes), schedule annual furnace tune-ups, and keep supply registers clear of furniture or rugs. In high-pollen seasons, run the fan on “circulate” mode to flush particles. For homes near the harbor or major roads, consider an inline electronic air cleaner to capture finer soot.

Frequently Asked Questions
My 1920s brownstone in Beacon Hill has original oil ducts—will cleaning cost more?
Yes. Oil-soot is sticky and often requires specialized brushes and extra containment, adding roughly $100–$250 to the base price. We’ll photograph the buildup before and after to show the improvement. Learn about oil-soot risks.
Why does my Arlington condo’s air still smell musty after a $199 duct cleaning?
A $199 “basic” clean often skips sanitization and coil cleaning. Musty odors usually come from mold in coils or drip pans. Adding sanitizer and coil treatment typically costs $125–$225 but eliminates the source. See why sanitization matters.
Can I skip cleaning the return ducts if I only clean the supply side in my Quincy home?
No. Return ducts pull air—and dust—back to the furnace. Skipping them leaves a major contamination reservoir. Whole-system cleaning ensures balanced airflow and prevents recontamination. Understand duct system balance.
Does Boston’s building code require air-duct cleaning for rental properties?
Boston’s rental code doesn’t mandate duct cleaning, but landlords must provide habitable air. Heavy mold or pest debris can violate the state sanitary code. We recommend cleaning every 3–5 years or after turnover. Check local rental rules.
I’m selling my Newton home—will a duct cleaning receipt help at inspection?
Yes. A dated receipt from a licensed company shows proactive maintenance, which reassures buyers and inspectors. Include it in your seller’s disclosure to avoid last-minute delays. See our maintenance documentation.
