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 Casselberry
HVAC cleaning in Casselberry runs $340-$620 for a full system on a typical ranch home, with evaporator coil cleaning adding $180-$290 when performed separately. Lake-adjacent homes around Lake Howell and Lake Triplet often need antimicrobial coil treatment on top of mechanical cleaning, which brings the total to $520-$810. If you’re seeing dust on registers shortly after the AC kicks on, or smell something musty when the blower starts, call CleanRun Air Duct Cleaning at (806) 606-6902. We give you a written price before a single panel comes off, and we photograph every duct run before and after.
Why CleanRun Air Duct Cleaning Is Casselberry’s Preferred HVAC Cleaning Company
We’ve worked enough homes off Red Bug Lake Road, along Semoran Boulevard, and through the neighborhoods around Wirz Park to know what Casselberry HVAC systems actually look like inside. Most are attic-mounted units in 1960s-1980s ranches with fiberglass duct board that’s been absorbing Florida humidity for four decades or more. Our HVAC Cleaning crews don’t show up with a shop vac and a coupon. They show up with Rotobrush and Nikro equipment, a camera, and a written scope of work. Tomas Reyes, who runs our crews, insists on photographing the inside of every duct run before and after, because the evidence is the only thing that separates real source removal from noise. Every technician is background-checked, uniformed, and identified by name before they step onto your property, per Haven Standard Clause 3.
Our customers in Casselberry consistently tell us the same thing: they’d rather see proof than hear promises. That’s why the Documented Photo Record is standard on every visit, not an upsell. We’ve been doing it that way since 2013, across more than 52,000 homes. Every one of those jobs started with a written price under Haven Standard Clause 1. No exceptions.
Our HVAC Cleaning Services in Casselberry

Air Handler Cleaning
In Casselberry’s lake-dense subdivisions, the air handler sits in an attic that routinely exceeds 150°F in July. Fiberglass duct board inside the unit absorbs moisture from the ambient air, and that moisture never fully burns off. We pull the blower assembly, clean the housing, and photograph the interior so you can see what was actually in there. In a 1978 ranch on Lake Howell Drive, our tech found black mold colonization on the duct board liner within three feet of the supply plenum. That’s not unusual here. We performed source removal with negative pressure and HEPA-filtered vacuuming, then applied an antimicrobial coil treatment to stop regrowth. That’s the protocol, not the exception.

Evaporator Coil Cleaning
A dirty evaporator coil in Casselberry costs you more than comfort. It forces your compressor to run longer, and that shows up on your FPL bill. We clean coils with professional-grade equipment from Abatement Technologies and Guardsman, then photograph the before and after. If your coil sits in a lakefront home near Lake Triplet, we’ll check for the microbial growth that sustained humidity encourages, and we’ll tell you plainly whether mechanical cleaning is enough or whether coil treatment is warranted. You’ll see the photo either way.

Condenser Cleaning
The condenser outside your Casselberry home deals with pollen from live oaks, pine needles, and the fine dust that blows off Seminole County roads. We clean the coil fins with the right pressure and the right chemistry, not a garden hose cranked to full blast. A condenser that can’t reject heat makes your whole system work harder, and in Casselberry’s climate, that’s a year-round problem, not a seasonal one.

Coil Treatment
For homes within a few hundred feet of open water, mechanical cleaning alone often isn’t enough. Condensation on supply ducts during cooling season creates the exact environment mold needs to return. We apply an antimicrobial coil treatment after cleaning when the photos show organic growth, and we document that application in the job record. If someone quotes you a coil cleaning in Casselberry and doesn’t mention whether the coil will be treated afterward, ask them how they’ll prevent regrowth. Then call us for a second opinion on their written estimate. That second opinion is free.

Common HVAC Cleaning Problems We See in Casselberry Homes

- Mold on fiberglass duct board in lakefront subdivisions. Homes around Lake Howell and Lake Triplet hold moisture longer than homes in Longwood or Oviedo, and 40-year-old duct board absorbs that moisture. The result is visible microbial growth within feet of the air handler. Mechanical cleaning alone won’t fix this; you need source removal plus antimicrobial treatment.
- Skipped camera inspection on aging duct systems. A positive-pressure cleaning method can blow dislodged mold spores into the living spaces of a tightly built Casselberry ranch. We use negative pressure and HEPA filtration to contain what we remove. If a contractor won’t show you a camera inspection before quoting, that’s a red flag.
- Condensation on supply ducts during cooling season. The sustained humidity near Casselberry’s lakes pushes supply ducts below dew point, and water accumulates. That water carries dust, creates mold conditions, and degrades duct board faster. Air handler cleaning is not optional in these homes.
- Shared duct systems in condo buildings. Multi-building lakefront communities often have supply and return ducts that serve multiple units. If one unit’s HVAC cleaning doesn’t account for the shared portions, the problem migrates right back. We schedule around HOA access windows and limited parking at these properties, and we document every section we clean.

FAQs - HVAC Cleaning in Casselberry

Homes within a few hundred feet of Lake Howell or Lake Triplet experience meaningfully higher ambient moisture than homes in Longwood or Oviedo, because the open water keeps attic and crawlspace humidity elevated even when the AC runs constantly. That moisture drives condensation on supply ducts during cooling season, which accelerates mold growth on fiberglass duct board. In practice, this means lake-adjacent Casselberry homes need antimicrobial treatment after mechanical cleaning far more often than homes a few miles inland. If you’re on Lake Howell Drive or any of the smaller lake streets, expect your HVAC cleaning to include a moisture and mold assessment as standard, not as an add-on. Call (806) 606-6902 and we’ll walk you through what we typically find in your specific neighborhood.
Most Casselberry homes built between 1965 and 1985 used fiberglass duct board that absorbs moisture and degrades in Florida’s attic heat. That liner sheds fibers and creates porous surfaces that trap mold spores and debris. Newer Oviedo construction typically uses insulated flex duct or sheet metal with exterior insulation, which is far less likely to harbor microbial growth. If your Casselberry home still has original duct board, plan on air handler cleaning every 2-3 years, and expect camera evidence of what’s growing in there. We’ll show you the photos before we recommend anything further. Call (806) 606-6902 for a written price on your system.
Yes. Shared dryer vent stacks in Casselberry condo buildings are one of the most neglected HVAC-adjacent systems we see. Lint accumulates at bends and junctions, reduces airflow, and creates a fire hazard. We coordinate with your HOA to schedule access, then clean the shared stack with professional equipment and document the before and after. One unit’s laundry habits affect the whole stack, so this isn’t a job to defer. Call (806) 606-6902 and we’ll work out a time that fits your building’s access window.
The most likely cause is that a previous cleaning used positive-pressure methods that dislodged mold spores from the duct board and blew them into your living space instead of containing them with negative pressure and HEPA filtration. This is exactly why we photograph every duct run before and after, and why we insist on source removal rather than surface agitation. If this is happening in your Casselberry home, we need to re-clean the affected runs properly and treat the source. A free second opinion on the previous contractor’s written estimate is available to you. Call (806) 606-6902 and we’ll schedule a camera inspection first.
In lakefront Casselberry homes, mechanical cleaning alone is rarely enough. The sustained moisture near Lake Howell, Lake Triplet, and Lake Concord creates condensation that re-establishes microbial growth on the coil and duct board within weeks if the surface isn’t treated. We photograph the coil before cleaning, and if the images show organic growth, we include antimicrobial treatment in the written scope. You’ll see the evidence with your own eyes, and you’ll decide with that evidence in front of you. Call (806) 606-6902 for a written price on your lakefront system.
