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.

AfterFast, Reliable Air Duct Cleaning Across Waltham
Air duct cleaning in Waltham typically costs between $450 and $1,100 for a full system, depending on home size, duct configuration, and how much debris has accumulated. Most Waltham homes we service fall in the $550-$750 range. We know the difference between a routine clean and a retrofit duct system that needs sealing work before cleaning can even begin. That distinction matters in Waltham more than almost anywhere else in the metro area, because so many of the city’s older homes have ductwork that was never part of the original construction. Call (806) 606-6902 and we’ll give you a written price before a single panel comes off.
Our crews know Waltham’s streets: Moody Street, Main Street, Lexington Street, and the winding side roads off Trapelo and Bacon. We know the triple-deckers, the capes in Warrendale, the converted mill lofts along the Charles. When you describe your home, we already have a mental picture of what your duct system likely looks like.
Why CleanRun Air Duct Cleaning Is Waltham’s Preferred Air Duct Cleaning Company
Waltham homeowners don’t need another vague promise. They need a written price, photographic proof the work was done, and a company that stands behind it. That’s how CleanRun Air Duct Cleaning has operated since 2013: 52,000+ homes served, every one with a written price before work started and a documented photo record when the crew left.
Tomas Reyes, our owner, built the business on a simple principle: show the customer what’s inside their ducts, explain what we found in plain language, and put the fix in writing. No urgency, no pressure, no bait pricing. The 365-Day Done Right Promise backs every job we do in Waltham. If something isn’t right, we make it right – in writing, not subject to a manager’s mood.
Our technicians are background-checked, uniformed, and identified by name before they arrive at your door. Equipment on the truck includes Rotobrush and Nikro negative-pressure systems, the same professional-grade tools used in commercial HVAC work. You can look up every machine we bring into your home before you agree to a price.
Our Air Duct Cleaning Services in Waltham
Residential Duct Cleaning
Waltham’s housing stock runs from 1890s two-families to mid-century capes in Cedarwood and newer construction near 02453’s western edge. Each type presents different ductwork challenges. We clean the entire system – supply, return, and air handler cabinet – using negative-pressure extraction that pulls debris out rather than pushing it deeper into the runs. Our Air Duct Cleaning team documents every run with before-and-after photos, so you see exactly what was removed.
Commercial Duct Cleaning
Waltham’s commercial properties along Main Street, Moody Street, and the office parks near Winter Street include restaurants, medical offices, and retail spaces. Commercial systems accumulate grease-laden dust in kitchen exhaust runs and construction debris in freshly renovated spaces. We schedule around business hours and provide the same documented photo record and written scope that residential customers receive.
Supply Duct Cleaning
Supply ducts in Waltham’s older homes are where we find the most dramatic problems. In retrofit systems, supply runs often lie disconnected inside wall cavities or sagging below uninsulated crawlspaces. We clean supply ducts from the air handler to each register, identify disconnections during video inspection, and flag runs that need sealing before cleaning is worthwhile. A supply duct that’s pulling air from a crawlspace will re-contaminate within weeks unless it’s sealed.
Return Duct Cleaning
Return ducts act as the lungs of your HVAC system, pulling air from living spaces back through the filter and air handler. In Waltham’s triple-deckers and converted mill units, return paths often run through unsealed framing cavities that draw dust, insulation fibers, and crawlspace air into the system. We clean return ducts thoroughly and identify bypass paths that need sealing so the system stops ingesting debris.
Video Inspection
Before we clean, we inspect. A camera run through each duct shows disconnected runs, crushed flex, and debris accumulation you’d otherwise never see. In Waltham’s retrofit ductwork – where installers threaded flex through wall cavities and dropped ceilings never designed for it – video inspection is not optional. It’s how we know what the real job is before any price is written.
Full System Cleaning
Full System Cleaning covers the entire HVAC system: supply and return ducts, air handler cabinet, blower fan, evaporator coil, and plenum. Waltham homes with retrofit systems almost always need full-system work, not just register-to-register cleaning. Debris collects in the plenum and blower cabinet where flex runs terminate poorly, and it recirculates through every register until it’s removed.

We service what’s already in your home and clean it properly, regardless of who installed it.
Common Air Duct Cleaning Problems We See in Waltham Homes
Waltham’s older housing stock creates a specific set of duct problems we see repeatedly. Here’s what we find most often:
- Sagging flex duct in retrofitted wall cavities. Waltham’s triple-deckers were built for radiator heat, so flex duct was threaded through spaces never designed for airflow. Runs sag, trap condensation near the Charles River’s humidity load, and become mold and biofilm reservoirs.
- Disconnected or crushed duct runs behind original plaster walls. Installers rarely cut adequate access panels during retrofits. Duct runs get crushed by framing or pull apart at connections, dumping conditioned air into wall cavities and pulling debris into the air handler.
- Mill-conversion condo ducts without insulating sleeves. The former Waltham Watch Factory complex and other Charles River mill buildings converted to residential lofts contain HVAC retrofitted into uninsulated 19th-century brick cavity walls. These ducts sweat heavily, collecting construction dust, rust flakes, and mold.
- Deep construction debris in gut-renovation systems. Waltham’s mill-conversion boom left behind drywall dust, plaster particles, and wood splinters inside duct runs. Standard cleaning with a shop vac won’t extract it. Negative-pressure extraction with HEPA filtration will.
Pricing for Air Duct Cleaning in Waltham, MA
Here are actual price ranges we write for Waltham homes:
- Full system cleaning, single-family home (1,200-1,800 sq ft): $450-$700
- Full system cleaning, larger home or retrofit with difficult access: $700-$1,100
- Supply duct cleaning only: $250-$400
- Return duct cleaning only: $180-$300
- Video inspection (standalone or included with full clean): $150-$250 when purchased separately
- Duct sealing (per run, where needed): $75-$150 per run, quoted before work starts
What moves the price in Waltham specifically: retrofitted systems with long flex runs and limited access panels take more time to clean properly. Mill-conversion units with ducts inside brick cavity walls require specialized equipment and careful maneuvering. A 1,200 sq ft ranch in Cedarwood will cost less than a Moody Street triple-decker with four separate apartment systems or a loft unit that requires working around original brick. You get one flat price per system, in writing, before any work starts. Bring us a competitor’s written estimate and we’ll put our number next to it – free second opinion, always.

FAQs - Air Duct Cleaning in Waltham
Your Waltham triple-decker was built before ductwork existed, so every duct run was retrofitted through wall cavities, dropped ceilings, and crawlspaces never designed for it. Cleaning those runs takes more time, more access work, and often more sealing than cleaning a purpose-built duct system in Weston. The 1890s-1930s construction, long flex runs, and limited access panels mean our technicians spend more labor hours on your system than on a comparably sized modern home. We quote the real price for the real job, in writing, before work starts. Call (806) 606-6902 to get your specific number.
Yes. We clean ducts in Waltham’s mill-conversion condos – including the former Watch Factory complex – without touching your original brick. Our technicians access duct runs through existing register openings and access panels. We don’t cut into walls or brick. The main challenge in these units is the HVAC retrofitted into uninsulated cavity walls, which traps condensation. We inspect first, identify where debris and mold are concentrated, and clean using negative pressure and HEPA filtration. We also flag ducts that need insulating sleeves to prevent the problem from recurring. Call (806) 606-6902 for an exact scope and written price.
A damp smell from your vents in Waltham’s South Side usually means condensation is pooling somewhere in your duct system, often in sagging flex duct or an uninsulated crawlspace run. Duct cleaning removes the mold and biofilm that has already formed, but if the underlying condensation problem isn’t fixed, the smell returns. That’s why we inspect during cleaning: if we find a disconnected or sagging run pulling moisture and debris into the system, we quote sealing as a separate line item before any work begins. The cleaning removes what’s there. The sealing stops it from coming back. Call (806) 606-6902 for a free estimate on a full inspection and clean.
Yes. Dryer vents and air ducts are separate systems with different failure modes. Your air ducts circulate conditioned air through your home. Your dryer vent carries hot, moist, lint-laden air from your dryer to outside. Cleaning one does not clean the other. In Waltham’s older homes, dryer vents often run long distances through walls and ceilings, accumulating lint at bends and restrictions. Lint is highly flammable, and a blocked dryer vent is a fire hazard. We offer dryer vent cleaning as a separate service, quoted separately, with its own photo documentation. Call (806) 606-6902 to schedule both.
Every 3 to 5 years for a retrofit system in Waltham, more frequently if you have pets, recent renovation work, or notice visible dust accumulation at registers. Waltham’s retrofit ductwork – installed in wall cavities and crawlspaces not designed for it – collects debris faster than purpose-built systems because runs are longer, often uninsulated, and frequently disconnected. If your home is a triple-decker or mill conversion near the Charles River, the added humidity accelerates mold and debris accumulation. We recommend an inspection every 2 years for these systems. Call (806) 606-6902 to schedule a video inspection and get a written recommendation based on what the camera actually shows.
Our owner Tomas Reyes built CleanRun on a simple idea: show you what’s inside your ducts, tell you what it costs to fix, and stand behind the work. That’s the whole promise. For Waltham homeowners with retrofit ductwork, a documented clean with photo proof is not a luxury. It’s the only way to know the job was actually done.
