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 Keystone
HVAC cleaning in Keystone costs between $420 and $780 for a typical single-system home, with larger estate properties running $900 to $1,400 depending on the number of zones and the condition of original flex duct runs. We schedule most Keystone jobs within five to seven business days, and every visit starts with a written price before a single panel comes off. Keystone isn’t a tract-home market. The houses here sit on acreage, many built between the 1980s and early 2000s, with duct systems that have been circulating stable dust, hay fiber, and Florida humidity for decades. We know what that does to a coil, a blower, and a flex run. Call us at (806) 606-6902 and we’ll walk through what your system likely needs before anyone gets in a truck.
Why CleanRun Air Duct Cleaning Is Keystone’s Preferred HVAC Cleaning Company
Keystone homeowners tend to do their research. They want to see the inside of a duct before they pay to have it cleaned. That’s exactly how we work. Since 2013, CleanRun has served more than 52,000 homes, and every one of those jobs produced a Documented Photo Record: the inside of every duct run, photographed before and after, delivered to the homeowner as part of the standard job record. No other company serving Keystone makes that promise in writing, on every job, without being asked.
We also put our price in writing before work starts. That’s H.A.V.E.N. Standard Clause 1, and it isn’t a courtesy, it’s the operating rule Tomas Reyes built this company around. Bring us a competitor’s written estimate and we’ll put our number next to it, line by line, at no charge. That’s the Free Second Opinion. Keystone homeowners have used it to catch inflated coil-cleaning quotes, misdiagnosed mold claims, and one memorable quote that included “hay removal” as a separate line item. We just call that cleaning.
Our crews dispatch from our Miami coordination office, but the technicians on your property are assigned to the Keystone area and know the roads: Gunn Highway, Patterson Road, Nine Eagles Drive. They know what to expect when a return-air grille on Race Track Road has been pulling barn air for a decade.
Our HVAC Cleaning Services in Keystone
We clean the entire air pathway, not just the parts you can see from the living room. On most Keystone jobs, that means source removal on the return side, coil and blower work at the air handler, and camera inspection of every supply run before we seal anything back up. Here’s what that looks like in practice.
Evaporator Coil Cleaning
Keystone’s equestrian properties put a load on evaporator coils that most HVAC contractors never see. Horse dander and hay fiber are fine enough to pass through a standard 1-inch filter, and once they hit a wet coil, they bind to it. The coil becomes a damp mat of organic material. We clean coils with professional-grade equipment and coil-safe treatments, then photograph the result. If your coil has been running dirty for years, cleaning it can restore a measurable amount of static-pressure drop, which on a multi-zone system is the difference between balanced airflow and one bedroom that never cools.
Air Handler Cleaning
The air handler is where Keystone’s specific problems converge: equestrian dust from the return side, attic heat degrading the cabinet seals, and wet-season humidity encouraging biological growth on the blower wheel. We pull the blower, clean the housing, clean the wheel, and inspect the secondary drain pan for the standing water that feeds mold. On older Keystone homes with original 1980s air handlers, we also check for rust at the blower motor mounts, a common failure point on systems that have been pulling damp, particulate-laden air for 35 years.
Condenser Cleaning
The outdoor condenser doesn’t care whether you own horses, but it does care about oak pollen, pine needles, and the fine dust that settles across Keystone’s semi-rural lots. A clogged condenser coil drives up head pressure and shortens compressor life. We clean condenser coils with water and non-corrosive coil cleaner, clear the surrounding drainage, and check the pad for the sinking that happens on large, soft-ground lots. It’s the least glamorous part of HVAC cleaning and one of the most consequential for system longevity.
Coil Treatment
After the evaporator coil is clean, we apply a coil treatment that slows re-soiling and inhibits microbial growth. For Keystone homes with stables upwind of the air handler, this treatment is doing real work between visits. We use products from manufacturers that publish their specifications, not mystery chemicals. Ask us which treatment we’re using on your coil. We’ll tell you, and we’ll show you the label.

BeforeAfterTrusted Brands We Service in Keystone
Keystone homes run on every major equipment brand: Carrier, Trane, Lennox, Rheem, Goodman, and a fair number of older York and Bryant systems still holding on. We service all of them. Our equipment roster includes Rotobrush air-jet agitation tools, Nikro HEPA-filtered negative-air machines, and Abatement Technologies containment systems. Those brand names matter because they’re verifiable. You can look them up before we arrive. If the house has a multi-zone system, which many Keystone estate homes do, we bring zone-by-zone pressure readings and camera inspection equipment so you can see the condition of each run, not just a summary. HVAC Cleaning at this level requires gear that a shop vac and a drill brush can’t approximate.
Common HVAC Cleaning Problems We See in Keystone Homes
- Original flex duct from the 1980s and 1990s, sagging in the attic. Keystone attics hit 130 to 140°F in summer, and that heat degrades the plastic liner inside flex ducts. The liner tears, the duct sags, and attic air (plus whatever’s in the attic) gets pulled into the supply stream. We find disconnected or crushed flex runs on a significant share of older Keystone homes.
- Barn and stable particulate loading on the return side. Homes along Keystone Road and Race Track Road with barns upwind of the air handler pull hay fiber and horse dander into the return-air grilles at rates that clog filters in two to three weeks. This isn’t a filter problem. It’s a source-load problem, and it requires mechanical removal of the material packed against the coil and inside the return plenum.
- Wet-season mold in supply ducts, especially on multi-zone systems. Keystone’s June-through-September humidity means any dead zone in a multi-zone supply run becomes a condensation point. When airflow slows in a rarely-used zone, the interior of that duct stays damp. Add organic dust from the equestrian environment, and you have the conditions for mold colonization inside the ductwork, not just on the coil.
- Blower motor overheating from filter neglect. On equestrian properties, filters clog so quickly that homeowners often can’t keep up with monthly changes. A loaded blower motor runs hot, the windings degrade, and the motor fails years early. We clean the blower and we tell you, in writing, what we found and what filter schedule your specific environment actually requires.
Pricing for HVAC Cleaning in Keystone, FL
Here are the numbers, in writing, because that’s the only way we quote. A single-system evaporator coil and air handler cleaning in Keystone typically runs $220 to $350. A full HVAC cleaning (coil, blower, air handler interior, and accessible supply and return runs) on a standard single-zone home runs $420 to $680. On a larger estate home with multiple zones and longer duct runs, expect $780 to $1,200. If we find disconnected flex runs, sealing adds $40 to $90 per connection, and we’ll show you the camera footage that justifies that line item before we do the work. If we find mold requiring source removal and sanitizing, that’s quoted separately, in writing, before anything starts. No per-vent pricing. No coups. One written price per system, agreed before work begins. That’s the whole point of HVAC Cleaning in Keystone done right.

FAQs - HVAC Cleaning in Keystone
Homes with stables upwind of the air handler, or with paddocks close to the house, typically need HVAC cleaning every 12 to 18 months instead of the 3-to-5-year interval common in non-equestrian neighborhoods. The reason is simple: hay fiber and horse dander load the coil and returns at rates that overwhelm standard filtration. If you’re changing filters every month and they’re coming out brown with fine organic material, your system is telling you it needs attention. Call (806) 606-6902 and we’ll camera-inspect the coil and return plenum to show you exactly what’s accumulated.
It depends on what the camera shows. Flex duct from the 1980s and 1990s can often be cleaned if the inner liner is intact and the duct is still properly suspended. But if the liner has torn, which we frequently find in Keystone attics that hit 130°F-plus, cleaning won’t fix the real problem. Torn flex pulls attic air and contaminated particulate into the supply stream before the duct ever gets dirty from normal use. We’ll show you the footage and recommend cleaning, sealing, or replacement based on what we actually see, not on a sales script.
That odor comes from organic material that has already passed through the filter and is now packed against the evaporator coil or lining the return plenum. A new filter doesn’t remove what’s already inside the system. The coil holds moisture, the organic material decomposes, and the blower pushes that smell through every register. The fix is mechanical source removal, a coil cleaning, and typically a coil treatment to slow re-soiling. Call (806) 606-6902 for a free estimate and we’ll show you the before photos of what’s actually in there.
Yes, it’s very common. Keystone’s custom homes on one to five acres are typically larger than standard tract houses and use multi-zone systems to control separate wings or floors. Multi-zone systems have longer, more complex duct networks with more connection points and more dead-end supply runs. Cleaning them takes longer, costs more, and requires more camera work to verify every zone was actually serviced. We price per system, not per vent, and the written quote reflects the actual duct layout of your house.
Yes, but only if the source of the moisture is addressed. Duct cleaning removes existing mold from the duct interior, the coil, and the blower, but if a dead zone in a rarely-used supply run continues to condense moisture every June through September, mold will return. That’s why we include a moisture assessment with every HVAC cleaning in Keystone. We’ll identify which runs are condensing, explain why, and recommend sealing or airflow adjustments where needed. The cleaning removes what’s there; the diagnosis prevents it from coming back. Call (806) 606-6902 to schedule an inspection.
If your Keystone home has equestrian particulates cycling through an aging duct system, you don’t need a coupon, you need documentation. We’ll show you the inside of your ducts before and after, put every price in writing before work starts, and back the work with the 365-Day Done Right Promise.
