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 HVAC Cleaning Across Chelsea
HVAC cleaning in Chelsea costs $425-$780 for a full system on average, depending on home size and how much debris has accumulated inside the coils and duct runs. That is a whole-system written price, agreed before we remove a single panel, not a per-vent bill that grows once the work starts. Chelsea homes sit under Logan Airport flight paths and beside the petroleum terminals along Chelsea Creek, so the HVAC systems here collect particulate at a rate most suburbs never experience. We clean evaporator coils, blowers, air handlers, and condensers with professional-grade equipment, and we photograph everything before and after so you can see the work was real. Call (806) 606-6902 and we’ll give you a written price on the spot.
Why CleanRun Air Duct Cleaning Is Chelsea’s Preferred HVAC Cleaning Company
We’ve worked in enough Chelsea three-deckers near Bellingham Square and Prattville to know what these systems actually look like inside. The housing stock here is dense, old, and retrofitted – three-deckers built for steam heat that later had forced-air ducts threaded through walls never designed for them. That produces irregular duct runs with extra joints and tight turns, which collect debris faster than clean, straight runs in newer construction. Our technicians understand those systems because we’ve opened hundreds of them. Tomas Reyes, who leads our crews, has spent years working through Chelsea’s specific HVAC problems, from rust scale in interstitial duct runs to coils caked in a mix of residential dust and aviation particulate.
Every Chelsea job includes a documented photo record of the inside of your duct runs, before and after. Not a single photo of a register with a flashlight – actual camera footage from inside the plenum, the trunk lines, and the elbows where debris builds up. Our written price comes before any work starts, per Haven Standard Clause 1, and it covers the entire system. We don’t charge per vent, and we don’t upsell from a low teaser number once the truck is outside. The 365-Day Done Right Promise backs all of it in writing: if the work isn’t right, we make it right.
Chelsea residents have told us they notice the difference in system performance and, more importantly, in what the camera shows them. When a technician can point to a before image showing a 3-inch debris build-up at the first elbow and an after image showing clean galvanized metal, that’s evidence. That’s the CleanRun way. Dispatch is coordinated from our Boston office, and crews serve Chelsea locally, so scheduling is straightforward and response times are measured in days, not weeks.
Our HVAC Cleaning Services in Chelsea
Evaporator Coil Cleaning
Evaporator coils in Chelsea homes are the single most common place we find the aviation-fuel particulate and diesel soot that defines this city’s air quality situation. The coil sits above your furnace or inside the air handler, and it gets wet during normal cooling operation. That moisture makes the coil surface sticky, and in Chelsea the stickiness traps whatever the outside air brings: soot from Route 1 truck traffic, particulate from planes descending into Logan, dust from the petroleum terminals along Chelsea Creek. Evaporator coil cleaning in Chelsea typically runs $150-$275 as part of a full system cleaning. We use negative-pressure extraction and HEPA-filtered equipment to pull the debris away without pushing it deeper into the ductwork.
Blower Cleaning
The blower motor and fan wheel are the workhorses of your HVAC system, and they live right next to the particulate you bring in every time you open a window on a summer night near Broadway. A dirty blower wheel loses efficiency fast – the fan blades get coated, airflow drops, and the system runs longer to hit the same temperature. Blower cleaning as part of a complete HVAC cleaning in Chelsea typically accounts for $100-$180 of the total written price. We remove the blower assembly, clean the wheel and housing, and check the motor for the kind of particulate accumulation that shortens its life in this environment.
Condenser Cleaning
Condenser units in Chelsea sit outside, exposed to everything this city throws at them: salt air from Chelsea Creek and Boston Harbor, diesel exhaust from Route 1 trucks idling at the lights near the Tobin Bridge, and airborne dust from industrial activity along the water. A blocked condenser coil forces the whole system to work harder, which raises your electric bill and shortens the life of the compressor. Condenser cleaning in Chelsea runs $120-$200 depending on access and how compacted the coil fins are. We rinse and treat the coils, clear the debris from the unit base, and verify the refrigerant levels while we’re there.
Air Handler Cleaning
Air handlers in Chelsea’s older multi-family buildings often hide the worst of what accumulates in a forced-air system. When three-deckers near Bellingham Square were retrofitted from steam heat to forced air, the air handlers often went into cramped basements or closets with poor airflow around the unit itself. That’s where we find the sticky, harbor-humidity-driven deposits that simple duct cleaning cannot reach. Air handler cleaning, including the blower, coils, and drip pan, typically runs $180-$320 as a component of the full system price. We also treat the coil surfaces to slow down re-accumulation between cleanings – coil treatment is standard on Chelsea jobs because of how fast particulate builds up here.

BeforeAfterTrusted Brands We Service in Chelsea
We service and clean all major HVAC brands found in Chelsea homes, and our crews carry stocked parts for the most common systems we see in the area’s three-deckers and multi-family buildings. The equipment we use on every job is professional-grade and verifiable: Rotobrush and Nikro for negative-pressure extraction, Abatement Technologies for HEPA filtration. If you’re the kind of homeowner who researches before you call, you can look up exactly what those brands do. They’re industry-standard workhorses, not shop-vacs painted to look professional. When an older unit in Chelsea needs a part, our familiarity with the local housing stock means we’ve probably already seen that system a dozen times this season.
Common HVAC Cleaning Problems We See in Chelsea Homes
- Aviation-fuel soot and diesel particulate in coil surfaces: Chelsea sits directly under Logan Airport approach paths and beside active petroleum terminals along Chelsea Creek. The same particulate that builds up on window sills and car windshields here also gets pulled into HVAC returns and caked onto evaporator coils.
- Rust scale inside older three-decker duct runs: In buildings near Bellingham Square and around City Hall, technicians frequently find that duct runs pass through uninsulated floor cavities where harbor-influenced humidity condenses against metal surfaces. Cleaning only the debris while ignoring rust scale leaves corroded metal shedding particles into the air stream, which defeats the purpose of the job.
- Patchwork retrofitted duct systems with extra joints and abrupt turns: Many Chelsea homes were built for steam or hot-water heat and converted to forced air later. Those retrofit duct runs have more elbows, more joints, and more dead spaces than original forced-air systems, which means they trap debris faster and require a cleaning approach that accounts for those irregular surfaces.
- Sticky, moisture-bound deposits that blow-through cleaning cannot remove: Chelsea’s proximity to tidal Chelsea Creek and Boston Harbor creates elevated ambient humidity. Combined with the city’s heavy particulate load, that humidity turns duct interiors into sticky surfaces. Blow-through cleaning methods simply push air past these deposits; negative-pressure source removal with HEPA filtration is what actually extracts them.

FAQs - HVAC Cleaning in Chelsea
Homes near Bellingham Square and along the Chelsea Creek corridor need HVAC cleaning every 18-24 months, compared to the national recommendation of 3-5 years. The reason is specific to Chelsea’s geography: constant exposure to aviation particulate from Logan Airport, diesel soot from Route 1 and the Tobin Bridge approaches, and industrial dust from the petroleum terminals means systems here accumulate debris at roughly double or triple the rate of homes in Revere or Malden. Humidity from the harbor makes the deposits stickier and harder to remove once they form. If you opened your system up and looked at the coil right now, chances are the camera would show build-up from the last year alone. Call (806) 606-6902 and we’ll show you exactly what’s in there.
Yes, and this is actually one of the most common system types we work on in Chelsea. Retrofitted three-deckers have duct runs that were fitted around existing joists, walls, and staircases, which means more joints, more elbows, and more tight spaces than you’d find in a purpose-built forced-air system. Our cleaning approach accounts for that: we map the duct runs with a camera before we start, then use negative-pressure source removal to extract debris from the irregular surfaces. In a three-decker near Bellingham Square, our tech found rust scale inside the metal supply trunks where they passed through uninsulated floor cavities – condensation from Chelsea Creek humidity had corroded the duct walls. We ran a camera inspection to map the damage, used negative-pressure source removal with HEPA-filtered air to extract the rust and soot, then treated the accessible coils and recommended duct sealing for the worst sections.
By the system. One written price covers the entire HVAC system – evaporator coil, blower, air handler, condenser, and all accessible duct runs – and that price is delivered before any work starts, per Haven Standard Clause 1. We don’t do per-vent pricing, and we don’t do the $79 coupon that turns into a $900 invoice once the technician starts counting registers. On Chelsea’s patchwork retrofitted systems with extra joints and tight turns, per-vent pricing actively incentivizes rushed work, because the technician’s income depends on moving fast rather than cleaning properly. Our pricing rewards thorough work, not speed. Call (806) 606-6902 and we’ll give you a written number for your exact system.
Not always, but rust scale has to be identified and addressed honestly. Light surface rust can often be cleaned and treated, especially if the rust is the result of condensation on the exterior of the duct rather than structural corrosion from the inside. But when rust has eaten through the metal or created holes that leak conditioned air into wall cavities, cleaning alone won’t fix the problem, and we’ll tell you that before you spend money on a cleaning. Chelsea’s harbor-humidity climate makes rust a more common finding here than in drier inland communities. The camera inspection tells us which situation you’re in, and we’ll show you the footage on the spot. No guesswork, no scare tactics, just documentation.
Yes, and this is standard on every Chelsea job, not an add-on. Before we start, we run a camera through your duct runs and photograph the interior surfaces – the plenum, the trunk lines, the elbows, the coil, everything. After the cleaning is complete, we photograph the same locations again. You receive the full documented photo record as part of the standard job, so you can see exactly what the inside of your ducts looked like before and what they look like when we leave. Our Chelsea customers tell us this is the single most convincing part of the whole experience, because they’re not taking anyone’s word for anything – they’re seeing their own ductwork with their own eyes. That’s the CleanRun standard, and it’s been our practice since 2013.
