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 Lexington
HVAC cleaning in Lexington means working inside homes where the ductwork is often older than the people living in them. Most of Lexington’s residential build-out happened between the 1950s and early 1970s, which means technicians here are rarely cleaning clean systems. We’re talking about original galvanized sheet-metal ducts, decades of accumulated dust, renovation debris from finished basements, and air handlers retrofitted onto runs never designed for them. CleanRun Air Duct Cleaning provides HVAC cleaning across Lexington with a written price before any work starts, a documented photo record of every duct run before and after, and crews who know exactly what to look for in mid-century Colonial, split-level, and ranch homes. Call (806) 606-6902 for a free estimate, and you’ll get a specific number, not a “we’ll see when we get there.”
In Lexington, the work is rarely as simple as a surface wipe. We’ll explain what our crews actually find inside these systems, what it costs to put right in this specific market, and why the sealed dead leg behind your finished basement wall matters more than you’d think.
Why CleanRun Air Duct Cleaning Is Lexington’s Preferred HVAC Cleaning Company
Homeowners in Lexington tend to research before they call. They want to see a written price, a documented process, and a warranty that means something. That’s how we’ve operated since 2013, and it’s why the detail matters here more than in most markets: Lexington homes are expensive, the ductwork is old, and the cost of getting it wrong is a repeat visit six months later with the same problem.
Every job we run in Lexington comes with a Documented Photo Record of every duct run, taken before and after, delivered as part of the standard job record. You see the inside of your own ducts, not a stock photo or a before-and-after from somebody else’s house. The 365-Day Done Right Promise backs that record in writing, not as a policy subject to manager approval. If the work isn’t right, we make it right.
Our technicians are background-checked and uniformed, identified by name before they arrive at your door under Haven Standard Clause 3: Verified Crews. They carry professional equipment from Rotobrush, Nikro, and Abatement Technologies, and they follow NADCA source-removal procedures. In Lexington, they know to check for the abandoned lateral branches that hide behind finished basement walls in 1960s split-levels. That’s the difference between a service that looks at your registers and one that inspects your entire system.
Our HVAC Cleaning Services in Lexington
Air Handler Cleaning
Your air handler is the box that moves conditioned air through your Lexington home, and in many mid-century houses near neighborhoods like Hastings Square, it’s working harder than the original system ever expected. A retrofitted high-efficiency unit on old galvanized trunk lines pulls different pressures than the original equipment. The result is dust, fiberglass liner particulates, and construction debris accumulating inside the handler itself. We remove and clean the blower assembly, housing, and coil cabinet, documenting it all with photos before and after.
Evaporator Coil Cleaning
The evaporator coil sits inside your air handler, and in Lexington homes with undersized or low-MERV filters, it gets coated with pollen, dust, and biological film. We see this constantly in East Lexington ranches and split-levels where spring pollen from the town’s dense tree canopy bypasses the filter. A coated coil reduces heat transfer, makes your system run longer, and drives up energy cost. We clean the coil with professional-grade equipment and document the result. In many cases, we also recommend a higher-MERV filter to keep it from re-coating within a season.
Blower Cleaning
The blower is the fan that pushes air through your ducts. When it’s dirty, it’s less efficient, noisier, and in some cases permanently out of balance. In Lexington’s heavy heating season, which runs October through April, the blower runs for six or seven months straight. That’s thousands of hours pulling air across a dirty coil, through debris-laden returns, and past whatever fell into the old dead-leg branches behind your walls. We clean the blower wheel, motor housing, and vanes, then run it under load to confirm it sounds and performs right.
Condenser Cleaning
The condenser is the outdoor unit. Lexington’s mature tree canopy means heavy leaf litter and pollen landing on the coil fins in spring and fall. We clean the condenser coil, check the fins, and confirm the unit is pulling proper airflow. It’s the only part of the system you can see without a camera, but it still deserves a documented record.

BeforeAfterTrusted Brands We Service in Lexington
CleanRun works on systems from every major manufacturer, but we see a lot of Honeywell air handlers, Aprilaire filtration systems, and Abatement Technologies components in Lexington homes. These are professional-grade brands with engineering specifications we respect, and we don’t make performance claims beyond what the manufacturer documents. What we do offer is the ability to assess whether your specific equipment is compatible with your existing ductwork, especially in century homes near the Battle Green where postwar retrofits often left undersized trunk lines.
Common HVAC Cleaning Problems We See in Lexington Homes
- Abandoned dead-leg branches hiding behind finished basement walls. In 1960s split-levels, an old lateral duct branch gets abandoned during a remodel and sealed with tape. That tape fails, the branch fills with construction debris and fiberglass liner, and every system cycle pulls that material back into the main trunk.
- Crushed or disconnected runs under finished floors. Renovation work in Lexington often means running wire, plumbing, or new framing through old duct chases. A crushed return line or a disconnected supply run now pulls dirt from inside the floor cavity instead of from the room it was meant to serve.
- Filter bypass from undersized or low-MERV filters. Lexington’s spring pollen load is heavy. A low-MERV filter on a high-efficiency air handler lets pollen through and deposits it on the blower motor and evaporator coil, where it bakes on over the cooling season.
- Fiberglass liner particulates shedding into the airstream. Original ductwork in many Lexington homes was lined with fiberglass for insulation. After 50 to 70 years, that liner degrades and sheds microscopic particulates into the air you breathe every time the system runs.

FAQs - HVAC Cleaning in Lexington
How do you find hidden dead-leg duct branches in Lexington split-level homes?
We run a camera through the main trunk and every accessible lateral run, looking for branches that were capped off or taped during past renovations. In a Hastings Square split-level, our crew found an abandoned lateral branch sealed with deteriorated tape, packed with decades of construction debris and fiberglass liner. Using camera inspection and negative pressure with agitation tools, we source-removed the accumulation per NADCA standards and sealed the dead leg, restoring proper airflow to the air handler. Without camera inspection, these branches get missed and keep feeding debris back into the system. Call (806) 606-6902 for an exact quote, and we’ll include camera inspection as part of the written scope.
What does a completed basement remodel mean for my HVAC cleaning in Lexington?
A finished basement remodel in a Lexington split-level or ranch often means old duct runs got buried behind drywall, and the work itself introduced drywall dust, sawdust, and insulation fragments into the system. We photograph every accessible run before and after, and if we find a disconnected or crushed run, we’ll quote sealing or repair as a separate written line item before doing the work. The point is that you see what we see, and you approve the fix before it happens.
Why does my Lexington home’s air handler need cleaning even if ducts look okay?
Because the air handler is where fine particulates settle after bypassing the filter. In Lexington’s October-to-April heating season, the blower runs for thousands of hours, and anything that got past the filter ends up baked onto the blower wheel, the motor, and the evaporator coil. Ducts can look clean to the naked eye at a register while the handler itself carries a visible layer of gray film. Our cleaning removes it, photographs it, and restores proper airflow.
Can you clean ducts in my pre-1900 Lexington home near the Battle Green?
Yes. Homes near the Battle Green often have forced-air systems that were retrofitted into century-old framing, which means non-standard trunk lines, tighter access, and occasionally undersized duct sizing for the equipment they’re now paired with. The cleaning procedure is the same: camera inspection first, written quote, source removal with negative pressure, and a documented photo record. These older systems often need sealing work on the joints, and we’ll quote that separately before any work starts.
How do Lexington’s mature trees affect my HVAC cleaning schedule?
Lexington has a dense, mature suburban tree canopy, and spring pollen loads here are heavy enough to overwhelm return-air filters and push particulates deep into duct interiors. If you’re running a low-MERV filter, a lot of that pollen ends up on the evaporator coil and blower motor. We recommend checking filter condition monthly during April through June, and scheduling an HVAC cleaning if you see visible pollen accumulation or if airflow at registers seems weaker than last season. Call (806) 606-6902 and we’ll walk through what you’re seeing before quoting anything.
