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.

Why CleanRun Air Duct Cleaning Is St. Johns’s Preferred HVAC Cleaning Company
St. Johns homeowners deal with a specific problem: the house is new, but the ducts are not. Builders in Northeast Florida rarely clean ductwork after the drywall phase, so the first owner inherits a system already coated in construction debris. That is the job we do most often here.
Every crew member is background-checked and uniformed, and they arrive carrying equipment from Rotobrush and Nikro. Before work starts, you get a written price under Haven Standard Clause 1. That means no one opens a panel and “discovers” an upcharge. When the job is done, you receive a documented photo record of every duct run, before and after, inside the supply and return lines. If anything is not right, the 365-Day Done Right Promise is in writing on your job record, not something you have to argue for later.
Tomas Reyes runs our HVAC Cleaning team, and he holds crews to the same standard on every St. Johns job: photograph what you find, write down what you will do, and do exactly that.
Our HVAC Cleaning Services in St. Johns
Evaporator Coil Cleaning
In St. Johns, the evaporator coil sits inside the air handler and does most of the humidity work. When drywall dust from construction coats the coil, it insulates the fins and blocks the condensation that removes moisture from the air. A coil caked with debris makes the system run longer, pulls more power, and leaves the house clammy. We clean the coil in place when the layout allows, or pull it for a deeper chemical treatment when the buildup is heavy. In a Durbin Crossing two-story with dual zones, we typically clean both coils in a single visit.
Blower Cleaning
The blower wheel moves air across the coil and through every duct run. In St. Johns homes built since 2010, the blower often carries a layer of fine drywall particulate from the original build. That reduces airflow and forces the motor to work harder. We remove the blower assembly, clean the wheel and housing, and photograph the before and after. A clean blower wheel in a two-zone RiverTown home usually shows an immediate change in airflow at the registers on the far end of the house.
Condenser Cleaning
The condenser lives outside and faces a different enemy in St. Johns: dust, pollen, and landscaper debris. Northeast Florida’s long cooling season means the condenser runs nine to ten months of the year. Grass clippings and construction soil from active subdivision builds collect on the coil fins and choke the heat exchange. We wash the condenser coil, clear the debris around the unit, and check the fan motor and capacitor while we are there. It is quick, but it matters more here than in places with shorter summers.
Air Handler Cleaning
The air handler cabinet in a St. Johns home often holds the worst of it: drywall dust settled in the bottom, insulation fibers caught on the internal panels, and sometimes the first signs of microbial growth where moisture condensed on dust. We open the handler, vacuum and wipe every surface, sanitize where warranted, and replace the filter with a fresh one as part of the job record. You get photos of the inside of the cabinet, not just a promise that it looks better.

BeforeAfterTrusted Brands We Service in St. Johns
Most St. Johns production homes run on a predictable set of systems: Carrier, Trane, Lennox, Rheem, and Goodman, with Honeywell controls on the higher-spec builds in Beachwalk and Julington Creek Plantation. We service all of them and keep common filters and coil cleaners in the truck. Our crews use Guardsman coil treatment and Rotobrush agitation tools, plus HEPA filtration from Abatement Technologies for negative-pressure extraction. If your system has an Aprilaire filter cabinet or a Honeywell zone controller, the crew will know it before they walk in because you will have described it over the phone, and we will have the right parts staged.
Common HVAC Cleaning Problems We See in St. Johns Homes
- Drywall dust inside the registers. This is the dominant issue in St. Johns. In Durbin Crossing and RiverTown, we regularly pull registers on homes that are three to five years old and find drywall dust compacted against the boot collars. The system has been running its entire life on debris from the original build.
- Insulation fibers in the return ducts. Builders cut return openings in the ceiling before the attic insulation is fully settled. Loose fibers get pulled into the return side and coat the blower and coil. If the returns in your St. Johns home have never been cleaned, they are almost certainly collecting insulation.
- Musty smell when the system first kicks on. That odor is usually organic debris inside the air handler or duct runs, holding moisture from St. Johns’s humidity. Once dust and drywall particulate sit damp for a few months, the smell becomes a fixture of the house.
- Reduced airflow to second-floor rooms. Dual-zone systems in large two-story production homes rely on every register flowing near design spec. Debris in the duct runs and on the coil slowly starves the far rooms. Homeowners notice hot upstairs bedrooms and assume the AC is undersized. Often the problem is a restricted system, not a weak one.

FAQs - HVAC Cleaning in St. Johns
Why would a new construction home in St. Johns need HVAC cleaning?
Because the ducts were never cleaned after the drywall and insulation phases, and the debris left inside has been there since the day you closed. St. Johns’s housing stock is overwhelmingly post-2010 production builds, and builders do not clean ductwork before handover as a standard practice. The system you are running today is pulling air through drywall dust and insulation fibers from the original construction. We recommend having a camera inspection done within the first year of ownership. Call (806) 606-6902 and a crew can pull a register in five minutes and show you what is inside.
What is that white dust around my registers in Durbin Crossing?
That white dust is almost always drywall particulate or blown insulation that was left in the duct runs during the build and is now being pushed out by the blower. It collects at the register edges because that is where the air velocity drops. It is not a sign that your system is failing. It is a sign that the ducts were never source-removed. A proper cleaning removes the debris at the source, not just at the visible register face. Call (806) 606-6902 for a free estimate, and we will photograph the inside of the duct run before and after.
How does St. Johns humidity affect my HVAC system if the ducts were never cleaned?
Northeast Florida’s humidity keeps the inside of the ductwork consistently moist during the long cooling season. If the ducts hold organic debris like drywall dust and insulation fibers, that moisture creates a perfect environment for mold and mildew. Clean ducts do not eliminate humidity, but they remove the food source that mold needs. That is why the post-construction cleaning matters more here than in a dry climate. Call (806) 606-6902 for a written scope and price.
Do I need to clean the evaporator coil in a new St. Johns home?
Yes, if the ducts were never cleaned, the coil is almost certainly coated in construction dust by now. The coil is the first surface the return air hits, so it catches a significant share of the drywall particulate before it enters the supply side. A coated coil restricts airflow, reduces dehumidification, and shortens the system’s life. We clean evaporator coils in St. Johns homes with a combination of compressed air, coil cleaner, and Guardsman treatment when the buildup is heavy. Call (806) 606-6902 for an exact quote.
Can I check for construction debris in my ducts myself before calling a professional?
You can do a basic check: remove a register cover on the second floor and look at the boot collar with a flashlight. If you see dust caked around the edges or fine white powder inside the duct run, that is debris from the build, and it extends beyond what you can see. Do not try to clean duct runs yourself with a shop vac; the debris is embedded along the entire run, and you will only pull what is directly at the opening. A camera inspection from a trained professional maps the full extent of the buildup. We include the camera inspection as part of the written estimate, and you keep the photos either way.
