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 Danvers
HVAC cleaning in Danvers is about more than clearing dust from vents. It’s about correcting what 50 to 70 years of North Shore humidity has been doing inside your ductwork. Most of the ranch homes and split-levels built across Danvers during the 1950s through 1970s still run on their original sheet-metal supply runs, strapped to uninsulated basement ceilings. Every summer, condensation forms inside that cold metal and feeds a mold cycle that repeats year after year. CleanRun Air Duct Cleaning has been documenting exactly this pattern in Danvers homes since 2013. We’re the HVAC Cleaning team that shows you the before photo before asking you to spend a dollar. Call (806) 606-6902 for a written price.
Why CleanRun Air Duct Cleaning Is Danvers’s Preferred HVAC Cleaning Company
Our reputation in Danvers is built on one practice we’ve held since the first job: every duct run is photographed before and after, and the photos are handed to you as part of the standard job record. Not a marketing promise. A deliverable. Homeowners off Maple Street, up toward the Danversport area, and throughout the neighborhoods near Endicott Park have seen what their own supply runs look like on camera, and that’s why they recommend us to neighbors. Led by Tomas Reyes, our crews carry professional-grade equipment from Rotobrush and Abatement Technologies, and every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. When a Danvers homeowner asks what was actually done, we don’t describe it. We show it.
Ductwork here sits in unconditioned basements. That’s not a guess, it’s the construction reality of Danvers’s postwar housing stock. We know where the moisture builds, which runs are most likely to be contaminated, and how to reach equipment in tight mid-century mechanical rooms without tearing your house apart. The 365-Day Done Right Promise backs every job in writing. That’s not subject to a manager’s mood. It’s a warranty you can hold in your hand.
Our HVAC Cleaning Services in Danvers
Evaporator Coil Cleaning
In Danvers’s humid summer climate, the evaporator coil is where condensation and airborne debris meet. A coil caked with dust and mold won’t just run inefficiently, it pushes that contamination through your supply runs every time the blower cycles. We clean the coil with professional-grade solutions, then photograph it before and after so you can see the surface actually changed. For the ranch homes near Locust Street or the colonials around the Danvers High School area, this is the single most underserviced part of the system. A typical evaporator coil cleaning in Danvers runs $180 to $340 depending on access and buildup.
Air Handler Cleaning
The air handler is the lung of the system, and in Danvers’s mid-century homes it’s often crammed into a basement corner or a narrow utility closet. We clean the blower wheel, housing, and surrounding plenum using negative-pressure extraction so debris doesn’t get redistributed through the house. If your air handler hasn’t been opened and documented in years, the camera usually tells the story. Expect $220 to $410 for a full air handler cleaning in Danvers, with the photo record included.
Condenser Cleaning
The condenser sits outside and takes the brunt of North Shore pollen, road dust from Route 1 and Route 128, and whatever your lawn mower throws at it. A clogged condenser forces the whole system to work harder and shortens compressor life. We clean the fins, clear debris, and check airflow across the coil. Most Danvers condenser cleanings run $150 to $280. It’s the most straightforward piece of equipment to clean, and also the most ignored.
Heat Exchanger Cleaning
On a gas furnace, the heat exchanger needs to be clean to transfer heat safely and efficiently. Dust and pet hair accumulate on the exchanger surface and burn off as that faint smell when the heat first kicks on in October. We inspect and clean the accessible surfaces, and we’ll tell you plainly if what we’re seeing warrants further HVAC technician review. This service typically runs $180 to $320 for Danvers homes, depending on furnace access and age.
Coil Treatment
After cleaning, we apply a coil treatment that resists microbial regrowth through the next humid season. For Danvers homeowners whose basement ductwork has already shown condensation-fed mold, this step is the difference between a cleaning that lasts and one that doesn’t. Conservatively budget $120 to $240 for coil treatment as part of a broader cleaning, less when bundled with evaporator coil or air handler work.

BeforeAfterTrusted Brands We Service in Danvers
The equipment in Danvers basements spans five decades of HVAC brands: Carrier, Trane, Lennox, Rheem, York, and plenty of older units that predate digital anything. We service all of them with the same documentation standard. Our techs run Rotobrush agitation tools for source removal and Abatement Technologies negative-pressure units with HEPA filtration. We keep common coil cleaning solutions and access fittings on hand specific to the brands most common in Danvers housing stock, so we’re not spending your time waiting on parts. That matters when your mechanical room is the size of a phone booth and you want us in and out.
Common HVAC Cleaning Problems We See in Danvers Homes
- Condensation-fed mold in uninsulated basement supply runs. Danvers’s mid-century ranches and split-levels route ductwork through unconditioned basements. Each North Shore summer, warm humid air hits cold metal and water forms inside the run. By August, that’s a mold source you can smell but can’t see. Cleaning removes the growth, and sealing or insulating the run prevents the cycle from repeating.
- Fifty-year-old duct seals that have simply failed. The original mastic and tape on 1960s sheet-metal ductwork in Danvers has dried, cracked, and separated. That means conditioned air leaks into the basement, and basement air, with all its dust and humidity, leaks into your system. We test and reseal accessible runs as part of HVAC cleaning when we find failures.
- Collapsed or separated duct sections in ranch crawl spaces. In Danvers’s slab and crawl-space builds, duct runs are often strapped in place and forgotten. Sections separate, sag, and tear. The camera shows it, and then we fix it. Duct repair is part of what makes HVAC cleaning here different from a shop-vac pass in a newer town.
- Shared stack contamination in Danvers condos and apartments. In multi-unit buildings, a single resident’s cleaning doesn’t stop debris from neighboring units pushing back through the stack. We clean the full accessible run and document what came from where, so condo boards and property managers in Danvers have a record that supports building-wide maintenance decisions.
Pricing for HVAC Cleaning in Danvers, MA
A full HVAC cleaning for a typical Danvers ranch or colonial runs $400 to $850, with the photo record included. Add evaporator coil treatment, and you’re in the $550 to $1,000 range. What moves the number is not your neighborhood, it’s the physical condition of the system: how many runs, how much contamination, whether the coil needs work, and whether the ducts need sealing. Nobody on our crew quotes a price over the phone without seeing the system, and nobody starts work without a written number in your hand. That’s Haven Standard Clause 1. Competitor quoted less? Bring it. We’ll put our number next to it in writing, free. Call (806) 606-6902 for a free estimate that doesn’t change when the van shows up.

FAQs - HVAC Cleaning in Danvers
Because the ductwork is strapped to an uninsulated basement ceiling just above a cold concrete slab. Warm, humid North Shore air enters the basement, contacts the cold metal ducts, and condensation forms inside the run. That moisture feeds mold even when the finished living space upstairs feels dry. Cleaning removes the mold; sealing or insulating the runs stops the condensation cycle. Our camera inspection documents the exact point where condensation is happening in your home. Call (806) 606-6902 to schedule a documented inspection.
We use negative-pressure extraction that pulls debris out of the system rather than blowing it into adjacent units. The equipment is HEPA-filtered, and we work from the access point in your unit. We also coordinate with property management in Danvers’s multi-unit buildings, like the larger complexes near Route 1 and 95, to identify which portions of the stack are shared and advise whether a building-wide cleaning is warranted. Your written record shows exactly what was in your portion of the stack before and after.
In most cases, yes. The utility closets in Danvers’s mid-century homes are notoriously tight, but our tools are designed for confined access. We open the blower housing, vacuum the wheel and motor with a brush attachment, and clean the surrounding plenum without pulling the furnace. If the motor is heavily impacted or the access is genuinely unsafe, we’ll show you the camera footage and give you a written scope for what additional work would entail. No surprises.
Cleaning removes the debris and mold causing the smell, and resealing the joints restores much of the airflow lost to leaks. The deciding factor is structural: if the camera shows collapsed sections, rusted-through runs, or severe separation, we’ll tell you plainly. We’ll quote repair versus replacement as separate line items with photos so you can see the condition yourself. Most Danvers split-levels we service need cleaning and sealing, not full replacement.
Every 3 to 5 years for most Danvers homes, and more frequently if you have pets, have done recent renovation, or your basement is chronically humid. Homes near the Danversport waterfront, where humidity runs higher, tend to need the shorter interval. After your first cleaning, we can tell you, based on what the photo record shows, what interval make sense for your specific house. Your written record becomes the baseline for every future cleaning. Call (806) 606-6902 to start that record.
