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 Mason
HVAC cleaning in Mason, OH means getting deep into the coils, blower, and air handler of a system that runs almost year-round in southwest Ohio’s humidity. Costs for a full HVAC cleaning in Mason typically range from $450 to $1,100 depending on system size and how much buildup has accumulated, and a proper job includes photographic documentation of what was actually inside. Every CleanRun visit starts with a written price before a single panel comes off. Call (806) 606-6902 to schedule.
We know Mason not as a dot on a map but as a set of specific neighborhoods: Kings Mill, Kingsgate, Heritage Oak, and the other 1990s and 2000s planned communities that now hold thousands of original duct systems approaching 25 to 30 years old. That age matters for HVAC cleaning in Mason, because what looks like a failing air conditioner is often a duct problem that a basic maintenance visit never finds. Our crews serve Mason directly, with scheduling coordinated from our Cleveland office.
Why CleanRun Air Duct Cleaning Is Mason’s Preferred HVAC Cleaning Company
Mason homeowners call us because we show them what we found. Not a summary. Not a vague report. Photographs from inside every duct run we clean, before and after, delivered as part of the standard job record. That practice has been in place since our first job in 2013, and it separates documented work from shop-vac noise.
Our technicians are background-checked, uniformed, and identified by name before they arrive at your door under Haven Standard Clause 3: Verified Crews. We carry professional-grade equipment from Rotobrush, Nikro, and Abatement Technologies, with HEPA filtration on source-removal jobs where it matters most. Mason customers consistently tell us the same thing: the photo record is the reason they recommend us to neighbors.
We also handle the repair and sealing work that other cleaning companies either miss or won’t touch. In Mason, that distinction matters more than it does in most cities, because of what 25 years of attic heat does to flex duct. More on that below.
Our HVAC Cleaning Services in Mason

HVAC cleaning is not one service. It is a set of specific tasks, each one addressing a different point in the system where buildup causes measurable problems: reduced airflow, longer run times, uneven temperatures, and higher utility bills. Here is what we actually do in Mason homes.
Evaporator Coil Cleaning
The evaporator coil sits inside the air handler and is the point where cold refrigerant absorbs heat from your air. In Mason’s humid summers, that coil stays wet while the system runs, and wet coils collect dust like flypaper. A 2,500 to 4,500 square-foot Mason home with a single system often runs the air conditioning 1,500 to 2,000 hours a year, and over three or four seasons that is enough to coat the coil in a dense mat that cuts airflow dramatically. Our techs photograph the coil before cleaning, remove the buildup without chemical damage to the aluminum fins, and photograph again after.

Blower Cleaning
The blower motor and fan wheel pull air across the coil and push it into the ductwork. A dirty blower wheel loses its aerodynamic profile, which means the motor spins faster to move less air. In Mason homes with second-floor bonus rooms, the blower is already working against long flex runs and multi-zone dampers, so a fouled wheel compounds an existing problem. Blower cleaning in a typical Mason two-story runs $180 to $340 as part of a full HVAC cleaning package.

Condenser Cleaning
The outdoor condenser coil rejects heat to the outside air, and in Mason it collects grass clippings, cottonwood seed, and the fine dust that blows through the subdivisions off the wooded creek corridors. A condenser that cannot reject heat makes the system run longer and hotter, which shortens compressor life. We clean the condenser coil, straighten bent fins, and check the refrigerant line insulation, which degrades faster in Ohio’s freeze-thaw cycles. Condenser cleaning in Mason typically runs $150 to $250.

Air Handler Cleaning
The air handler cabinet houses the blower, the evaporator coil, and the return-air plenum. When you open one in a Mason home that has never had the air handler serviced, you find what we call a stratified mess: construction dust from the original build, pet hair, and a fine gray powder that is actually carpet fiber and dead skin cells, all glued to surfaces by condensed humidity. Cleaning the air handler properly means removing and washing the blower wheel, hand-wiping the cabinet interior, and vacuuming the return plenum with HEPA filtration. We do this as a standard part of our HVAC Cleaning service, not as an add-on line item.

AfterTrusted Brands We Service in Mason
The equipment in Mason homes spans the major residential brands, and our techs work on all of them: Honeywell controls, Aprilaire air quality products, and the full range of Goodman, Carrier, Trane, and Lennox systems common in local subdivisions. Because Mason’s housing stock is so consistently sized and configured, we keep the components and materials our crews need for typical jobs on the truck: blower wheel pullers, coil cleaning solutions graded for aluminum fins, mastic, and replacement flex duct in standard diameters. When a failed component needs replacement, we install OEM or equivalent parts and photograph the old part next to the new one for our records.
If you live in Mason and you are not sure what brand your system is, the photo record from your first cleaning is usually the quickest way to find out. We document equipment labels as part of the job.
Common HVAC Cleaning Problems We See in Mason Homes

- Sagging flex ducts above second-floor bonus rooms. Mason’s 1990s planned communities, especially Kings Mill and Kingsgate, were built with long flex-duct runs to serve bonus rooms above garages. After 25 years of southwest Ohio attic heat, those runs sag between truss junctions, and the sag becomes a debris trap that starves the bonus room register. Homeowners often replace the blower motor before anyone looks at the duct run itself.
- Stuck or leaking multi-zone dampers. Original 1990s zone dampers stick or leak after decades of thermal cycling. During a source-removal cleaning, a leaking damper means we cannot fully isolate one zone for negative-pressure extraction, so the zone does not get the cleaning it needs. We test damper function as part of the job and document what we find.
- Condensation and mold in finished-basement ceiling ducts. Finished basements are common in Mason, and the ducts running through those ceiling cavities collect condensation from humid southwest Ohio summers. Over time, that moisture supports mold growth on the inner duct liner. Brush-only cleaning does not remove it. We use HEPA-filtered negative-pressure extraction and, where the liner is compromised, we recommend replacement rather than coating over mold.
- Original construction debris still trapped in supply runs. We regularly find drywall scraps, sawdust, and even stray fasteners in the supply runs of Mason homes built in the late 1980s and 1990s, especially in the runs that were connected before the drywall crews finished. The builder’s final walkthrough never looked inside the ducts. It is still there 25 years later, recirculating dust into the house every time the fan runs.

FAQs - HVAC Cleaning in Mason

Because the cleaning never addressed the real problem: a collapsed or kinked flex run. In Mason’s 1990s planned communities like Kings Mill, bonus rooms were commonly served by long flex-duct runs routed through hot attic spaces. After 20 to 30 years, those runs sag at truss junctions or kink on sharp turns, which restricts airflow far more than any amount of dust inside the duct. A camera inspection identifies the kink; a repair replaces the crushed section and seals it with mastic. If your bonus room still gets weak airflow after a cleaning, the issue is structural, not cosmetic. Call (806) 606-6902 and we will show you the camera footage.
It depends on the condition of the run, which we determine by camera inspection before making any recommendation. Flex duct that is clean, intact, and properly supported usually does not need replacement. Flex duct that has sagged between supports, developed pinholes, or collapsed at a bend will continue to trap debris and restrict airflow no matter how many times it gets cleaned, and in those cases replacement is the honest answer. We photograph what we find and show you before recommending replacement. A typical flex-run replacement in a Mason attic runs $250 to $600 per run depending on length and accessibility.
Through the register openings and accessible branch points. Most finished basements in Mason were built with standard floor registers or wall registers that give us access to the supply runs, and we use a combination of negative-pressure extraction and agitation tools to reach the full length of the run from that access point. We do not cut into drywall. If a specific run is inaccessible from any register, we will tell you in writing before the job starts and work with you on the least invasive access point. The photo record includes images from every run we serviced.
Because the conditions that caused the mold were never corrected. Mold in attic ducts is typically driven by condensation, which forms when warm, humid air from the living space meets a cold duct liner in the attic. If the duct insulation is insufficient, damaged, or missing, or if the attic has a ventilation problem, the condensation persists and the mold returns. Cleaning removes the existing growth, but after the clean, the fix is addressing airflow, insulation, and humidity, not another round of cleaning alone. We document the cause in our photo record and give you a written explanation of what needs to change so the cleaning actually holds.
Plan on 4 to 7 hours for a full HVAC cleaning on a 3,500 to 4,500 square-foot Mason two-story with multiple zones. The time is driven by the number of duct runs, the number of zones, and how much buildup has accumulated over 20 to 30 years. A rushed job cannot deliver source removal properly, and we will not rush one. The written price you receive before work begins includes that time, and the photo record we hand you at the end proves what was done in it.
