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.
Fast, Reliable HVAC Cleaning Across Braintree
HVAC cleaning in Braintree means removing the debris, soot, and biofilm that accumulates inside your furnace, evaporator coil, blower, and air handler over years of New England heating and cooling cycles. For most Braintree homes, a full system clean runs $425-$880 depending on system size and what’s actually coating the components, and we provide a written price before any panel comes off. If you’ve never had your system opened up, you’ll want to know what’s in there. Call (806) 606-6902 and we’ll schedule a walkthrough with a camera inspection included.
We work throughout Braintree weekly, from Braintree Highlands to South Braintree to East Braintree near the Weymouth Back River. The housing stock here is specific: 1950s and 1960s split-levels, raised ranches, and Capes with original trunk-and-branch duct systems that have been moving air for sixty years. That history shapes what we find, and it shapes how we clean.
Why CleanRun Air Duct Cleaning Is Braintree’s Preferred HVAC Cleaning Company
Our HVAC Cleaning team operates on a straightforward principle: we document what we find, we price the work in writing before starting, and we photograph every component before and after. Homeowners around Braintree tell us the same thing: they’ve had companies come through, run a vacuum for an hour, and leave no record of what was actually done. CleanRun has been doing this since 2013, and every one of our 52,000+ jobs ends with a documented photo record of the inside of the system. You see the difference. We don’t ask you to take our word for it.
Tomas Reyes leads our crews, and every technician who arrives at a Braintree home is background-checked, uniformed, and identified by name before setting foot inside. Our license number is published on the page, not hidden in a footer. That matters when you’re letting someone open up the equipment that moves the air your family breathes.
Braintree homeowners also get the 365-Day Done Right Promise on every job, in writing. If the work isn’t right, we make it right. That’s Haven Standard Clause 4, and it’s not subject to a manager’s approval. It’s a written guarantee on the work order.
Our HVAC Cleaning Services in Braintree

Evaporator Coil Cleaning
Your evaporator coil sits in the air handler and pulls heat out of the air during summer. In Braintree’s coastal humidity, that coil is wet for weeks at a time. Dust sticks to it. Then pollen. Then it becomes a mat that blocks airflow and feeds microbial growth. A typical evaporator coil cleaning in Braintree runs $180-$320, and we remove the coil or access it in place to clean both the inlet and outlet faces. You’d be surprised how often the side facing away from the technician never gets touched.

Blower Cleaning
The blower wheel moves air through the system. When its curved blades are caked with dust and oily residue, it moves less air and pushes your system to work harder. In homes that converted from oil to gas heat, we often find the blower carries the same sticky petroleum film that coats the ductwork. Blower cleaning in Braintree typically runs $140-$240. It’s the component most likely to be skipped by a company in a hurry.

Condenser Cleaning
The outdoor condenser is exposed to everything Braintree weather throws at it: salt air drifting from Massachusetts Bay, pollen from spring, leaves from the mature oaks that line streets throughout South Braintree. We clean the fins, remove debris from the housing, and check the coil for corrosion. Condenser cleaning runs $130-$220. If you live within a mile of the Weymouth Back River estuary, that salt exposure is worth addressing at least every other year.

Air Handler Cleaning
Air handler cleaning is the deepest level of service, and it’s what most Braintree split-levels and raised ranches actually need. We open the cabinet, clean the blower assembly, evaporator coil, condensate pan and drain, and the internal insulation surfaces where mold tends to establish. Air handler cleaning in Braintree runs $350-$600 depending on access. Long horizontal runs beneath subfloors and low-clearance plenum areas make access harder here than in newer construction, but that’s exactly why the work matters.

We service all major residential equipment: Carrier, Trane, Lennox, Rheem, Goodman, Bryant, and York, plus older brands still running in Braintree’s 1970s homes. When components need replacement, we carry common parts for most residential systems and can source the rest quickly. For coil cleaning and microbial encapsulation work, we use trade-recognized equipment from Rotobrush, Abatement Technologies, and Nikro. These are professional-grade tools you can look up independently before agreeing to a price.
Common HVAC Cleaning Problems We See in Braintree Homes

- Sticky fuel-oil soot on original galvanized ductwork. Homes in Braintree Highlands and South Braintree that converted from oil to gas still carry a tacky, petroleum-based film on their trunk lines. Standard vacuum cleaning won’t remove it. It requires agitation tools and encapsulation.
- Microbial growth from coastal humidity. Proximity to the Weymouth Back River estuary and Boston Harbor’s air mass means interior coils stay damp longer. Biofilm forms faster here than in inland Norfolk County towns, and it doesn’t respond to fogging sanitizers alone.
- Asbestos-containing duct tape on pre-1978 systems. Many of Braintree’s original trunk lines were sealed with asbestos tape. We identify it before beginning work, not after agitating it. Haven Standard Clause 2: Documented Assessment before any equipment touches the system.
- Compacted debris in low-clearance plenums. Split-level designs with horizontal runs under subfloors trap debris at elbows and transitions. A camera inspection shows the build-up before cleaning begins, so we know where the problem is, not just that one exists.

FAQs - HVAC Cleaning in Braintree

The smell is coming from residual fuel-oil soot that remains on the interior surfaces of your original galvanized ductwork from the decades when the home ran an oil-fired furnace. When your gas furnace heats those ducts, the oily residue re-volatilizes, producing that petroleum smell that lingers even years after conversion. Standard vacuum-only cleaning will not remove this. It requires mechanical agitation, negative-pressure extraction with HEPA filtration, and a low-VOC encapsulation of the interior surfaces. Last fall we opened up a split-level in South Braintree that had been converted in the late 1990s; the original supply trunk still carried a tacky, petroleum-based soot film the homeowner thought was gone after conversion. Our crew ran a camera inspection to locate the heaviest deposits, then used Rotobrush agitation tools under negative pressure with HEPA filtration to break the oily residue off the duct walls before it could re-volatilize each time the gas furnace cycled. We treated the accessible interior surfaces with a low-VOC encapsulation after source removal so the odor wouldn’t creep back during the next heating season. Call (806) 606-6902 to have us inspect your system; the camera will show exactly what’s still in there.
Yes, it does. Homes built before 1978 in Braintree Highlands and similar neighborhoods commonly have asbestos-containing duct tape or duct board on original trunk lines. Before any agitation begins, our technicians visually inspect accessible duct surfaces for asbestos-containing materials. If we identify it, we stop and provide written guidance on abatement options before any cleaning work proceeds. We never agitate a surface that might release fibers into a tight split-level plenum. That’s a documented step in our process, not an optional add-on. Call (806) 606-6902 to schedule an inspection.
No. Fogging sanitizers treat the air passing through the system, but they do not remove the biofilm and microbial growth attached to duct surfaces, coil fins, and plenum walls. In Braintree’s coastal humidity, any organic material left on those surfaces provides a substrate for regrowth within weeks. The only effective approach is mechanical source removal first: physically cleaning the surfaces, extracting the debris under negative pressure, and then applying an EPA-registered antimicrobial if microbial growth is confirmed. Fogging without source removal is a temporary cosmetic measure. If a company proposes fogging as the primary solution for mold in your South Braintree ductwork, ask what they’re doing about the film on the surfaces. Call (806) 606-6902 for a camera-based assessment.
Expect to find significant accumulation at every elbow and transition point. In a home of that era with original trunk-and-branch ducting, we typically see a 2- to 4-inch debris bed at the first elbow of the supply trunk, dust caked onto the blower wheel blades, and a visible coating on the evaporator coil. If the home ran oil heat for decades, expect the sticky petroleum film mentioned above. We document all of it with a camera before cleaning, and photograph every run after cleaning so you can verify the work. The standard job record includes both before and after images. Call (806) 606-6902 for a free estimate with camera inspection.
Homes within a mile or two of the estuary experience persistently elevated summer humidity and some salt-laden air. That humidity keeps interior system components damp for extended periods, accelerating mold and biofilm growth inside duct runs and on coil surfaces. Salt in the air also accelerates corrosion on outdoor condenser units, especially fins and fasteners. Practically, this means Braintree homeowners near the water should plan on evaporator coil and air handler cleaning more frequently than people further inland: every 2 to 3 years rather than every 3 to 5. Call (806) 606-6902 to discuss what your specific system needs based on where you live.
