Air Duct Cleaning in Belmont, MA
Air duct cleaning in Belmont typically costs $350–$850 for a full residential system, with most jobs completed in a single morning or afternoon. We’re usually on Payson Road, Belmont Hill, or the town center within a day or two of your call. Belmont’s known as “The Town of Homes” for a reason—this zip code, 02478, packs in one of the densest concentrations of pre-WWII housing in Greater Boston, and Scott handles every job personally after 11 years focused on these exact systems. Call (888) 597-5659 for a free estimate.
Why Belmont Homes Are Different
Belmont’s housing stock is dominated by pre-WWII homes—many built 1900–1940—that were originally heated by coal-fired gravity furnaces with large “octopus” plenum duct systems. These converted systems carry 80-plus years of accumulated debris, often including residual coal soot from the pre-oil-conversion era, making Belmont duct cleaning jobs substantially more intensive than work in postwar suburbs like neighboring Waltham or Burlington. Greater Boston’s cold winters mean Belmont furnaces run four to five months continuously, cycling significant volumes of air through aging ductwork; combined with humid summers that promote condensation in uninsulated basement duct runs, the town sees elevated risk of mold and particulate buildup compared to drier inland climates.
Air Duct Cleaning in Belmont
Technicians working older Belmont Hill and Payson Road-area homes regularly encounter original octopus-style trunk plenums with 18-to-24-inch round main ducts—uncommon in postwar construction—where a telescoping brush kit designed for 8-inch rectangular runs is essentially useless, and where the first cleaning in 60-plus years can yield blackened debris consistent with legacy coal combustion residue. We use Rotobrush brush-system technology with extended brush attachments and Nikro HEPA vacuums built for commercial-grade suction. Air Duct Cleaning is our core service, and we clean it, repair it, and seal it so your 1920s system performs like it should.
Residential Duct Cleaning
Belmont’s Colonial Revival and Tudor Revival homes weren’t built for modern forced-air retrofitting. We regularly encounter original large-diameter round sheet-metal ductwork in properties around the town center—18-to-24-inch trunk diameters that standard residential vacuum equipment isn’t rated to handle. A full system cleaning for these pre-WWII homes with oversized ductwork typically runs $550–$850, compared to $350–$550 for postwar homes with standard 8-inch rectangular runs. We serviced a 1920s Colonial Revival on Payson Road where the original octopus plenum had 22-inch trunk ducts caked with coal soot; using a Rotobrush with an oversized brush kit, we extracted over 50 pounds of debris the homeowner hadn’t felt missing in years.
Supply Duct Cleaning
Supply runs in Belmont’s pre-war homes often branch from octopus-style plenums through uninsulated wall cavities and basement soffits. Humid summers promote condensation in these runs, and without aggressive cleaning, mold and particulate buildup recirculates through every room. We map your supply topology before starting—critical in homes where original blueprints were lost decades ago. Video inspection, standalone or bundled, runs $150–$250 and prevents surprises in systems with unknown histories.
Why does my 1920s Belmont home have such large ductwork that seems impossible to clean?
Your oversized ductwork is original to the coal-fired gravity furnace era—18-to-24-inch round trunk plenums were standard before forced-air conversion, designed to move heat by natural convection rather than blower pressure. Standard telescoping brushes rated for 8-inch rectangular runs are essentially useless here; we use Rotobrush equipment with oversized brush kits specifically configured for Belmont’s pre-WWII housing stock. Call (888) 597-5659 and Scott will assess your duct diameters before scheduling.
Dryer Vent Cleaning in Belmont
Dryer vent cleaning in Belmont typically costs $150–$350 depending on vent length and condition, with most jobs completed in under two hours. If you’re on Belmont Hill, near Payson Road, or closer to the town center in 02478, our Dryer Vent Cleaning service addresses the narrow legacy ducting and coal-era debris that make Belmont homes different from newer construction.
Vent Cleaning & Lint Removal
Standard lint removal tools fail in many Belmont homes. Legacy narrow ducting traps lint more aggressively than modern 4-inch runs, and decades of accumulated debris—sometimes including residual coal soot from original gravity furnace systems—can harden into a cake that basic brushes won’t dislodge. We use Rotobrush equipment with small-diameter adapters designed for these exact conditions, paired with Nikro HEPA vacuum extraction. A standard dryer vent cleaning runs $150–$250 for accessible 4-inch ducting in good condition, while homes requiring coal-soot remediation or mold treatment in uninsulated runs may reach $400–$650.
Vent Rerouting
When original vent runs are too narrow, too corroded, or improperly connected to defunct structural elements like old coal chutes, cleaning alone isn’t enough. We reroute to current safety standards using proper 4-inch rigid ducting, sealed joints, and correct termination points. Vent rerouting in older homes with narrow legacy piping typically falls in the $300–$550 range. We handle the full scope so you’re not calling another contractor next year.
What’s the most common dryer vent problem in Belmont Hill homes?
Belmont Hill’s concentration of 1920s–1930s Colonials and Tudors means we most often encounter original narrow ducting that has never been cleaned, combined with uninsulated basement runs that have corroded or separated at joints. The first cleaning in 60-plus years typically reveals significant blockage and often hidden damage requiring repair or rerouting. Call (888) 597-5659 for an inspection—estimates are free.
HVAC Cleaning in Belmont
HVAC cleaning in Belmont typically runs $280–$650 for a full system service and takes three to five hours in the town’s older homes with oversized ductwork. If you’re living in a pre-WWII Colonial Revival near Belmont Hill or a converted gravity-heat home off Payson Road, you already know these systems weren’t built for modern quick-clean methods. HVAC Cleaning from Everest means Scott handles every job personally.
Evaporator Coil Cleaning
Belmont’s humid summers drive heavy condensation across evaporator coils, particularly in homes with aging insulation or basement air handlers. When coils clog with dust and biological growth, airflow drops and your system works harder for less output. We access and clean coils properly—removing the housing when necessary, not just spraying cleaner through a grille. Evaporator coil cleaning typically runs $180–$320, with older Belmont homes trending toward the higher end due to access challenges.
Air Handler Cleaning
The air handler is the heart of your forced-air system, and in Belmont’s converted gravity-heat homes, it’s often been retrofitted into a space never designed for it. We clean blower wheels, housings, and return plenums where decades of sediment accumulate. Our truck-mounted Nikro HEPA vacuum pulls debris that portable units leave behind—critical when you’re dealing with 80-plus years of layered buildup. Full air handler cleaning runs $280–$450, while a complete HVAC system cleaning including coils, blower, handler, and ducts ranges $480–$850.
How long does a full HVAC cleaning take in a typical Belmont residence?
Three to five hours for most Belmont homes, extending to six or more for large properties with extensive octopus ductwork or multiple air handlers. The 02478 zip code’s pre-WWII stock simply takes longer than a 1990s split-level in Waltham—we don’t rush to beat parking restrictions or fit arbitrary time slots. Scott schedules realistic blocks and works until the job is complete. Call (888) 597-5659 to book with accurate time expectations.
Duct Repair & Sealing in Belmont
Most Belmont homeowners pay between $450 and $1,200 for full duct sealing, with spot repairs on flex or metal runs running $180–$400. We know Belmont’s streets well—from the winding roads of Belmont Hill down to the town center near Concord Avenue and out toward Payson Road—and we understand that Duct Repair & Sealing in these homes means working with soot-compromised surfaces that tape simply won’t stick to.
Duct Sealing
Belmont’s converted gravity systems leak air at every joint where original round trunk lines meet newer rectangular branch ducts. These leaks force your furnace to run longer, heat unevenly, and waste fuel during those four-to-five-month New England winters. We seal these conversion joints with fiberglass mesh and mastic, not duct tape—tape fails within months on the soot-laden surfaces common in pre-oil-conversion ductwork. A typical full-system seal in Belmont runs $650–$1,200 depending on accessible linear footage.
Metal Duct Repair
Original round sheet-metal trunk lines in Belmont’s 1900–1940 homes can corrode through at low points where condensation collects, or separate at longitudinal seams after decades of thermal cycling. We repair metal ducts with patch panels, sheet-metal screws, and two-coat mastic application. Where corrosion is extensive—common in uninsulated basement runs near the foundation wall—we’ll show you the damage and discuss repair versus replacement honestly. Metal duct repairs generally fall between $250–$500 per section.
My 1920s Belmont home has original round sheet-metal ducts. Can you still repair and seal those old systems?
Yes. We regularly repair and seal original round ductwork in Belmont’s pre-WWII homes, including the oversized 18-to-24-inch trunk lines common around Belmont Hill. These systems require specialized equipment—standard residential brush kits won’t reach, and telescoping tools designed for 8-inch rectangular ducts are useless here. We use Rotobrush systems with extended attachments and apply mastic with long-handled tools built for large-diameter round metal. Call (888) 597-5659 and we’ll inspect your specific configuration.
Air Quality & Sanitizing in Belmont
Air quality sanitizing in Belmont typically costs $280–$650 depending on home size and contamination level, with most jobs completed in a single visit. We’re familiar with Belmont’s streets—from Belmont Hill down to Payson Road and the town center—and we know the access challenges that come with this dense, historic community. Air Quality & Sanitizing from Everest targets the source, not the symptoms.
Mold Treatment
Belmont’s humid summers and cold winters create ideal conditions for mold in uninsulated basement ductwork. We see this constantly in homes around Belmont Hill, where original gravity-duct conversions leave 18-to-24-inch round mains running through damp, unfinished cellars. Our mold treatment protocol starts with HEPA pre-vacuuming using Nikro equipment—not surface spraying that just pushes spores deeper. A typical mold treatment in Belmont runs $340–$580 for homes under 2,500 square feet.
Odor Removal
Persistent odors in Belmont homes often trace to three sources: legacy coal soot reactivated by furnace heat, pet dander trapped in decades of duct sediment, or mold in uninsulated basement runs. Standard air fresheners mask these; we eliminate them at source. Our odor removal combines source identification, HEPA extraction, and targeted oxidizing treatment, typically running $320–$520 depending on source complexity and depth of duct contamination.
My Belmont home has original octopus ductwork. Can you still sanitize it effectively?
Yes—octopus ductwork can be sanitized effectively, but only with equipment rated for its oversized dimensions and with pre-vacuuming that removes accumulated debris rather than pushing it deeper. We use Rotobrush systems with extendable brush heads and Nikro HEPA vacuums capable of handling 18-to-24-inch round mains. Standard residential equipment often fails to contact the full interior surface, leaving active contamination. Call (888) 597-5659 and we’ll inspect your specific plenum configuration.

What Belmont Customers Say
"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
— Rami Hassan"Found a disconnected run in the crawlspace while they were in there and told me about it rather than cleaning around it."
— Aisha Boyd"Ran a negative air machine on the whole system rather than the shop vac on a stick that the cheap outfit down the road uses. Showed me the before and after photos from inside the trunk line and it was genuinely disgusting."
