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.
Air Duct Cleaning Company in Clermont, FL
Air duct cleaning in Clermont typically runs $350 – $650 for a whole-home system, with most jobs scheduled within a few days rather than weeks. We’re Hollis Air Duct Cleaning, and we serve Clermont homes with the same discipline we apply everywhere in our territory: written price before work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise backed in writing. Clermont’s humidity and heat-pump-heavy HVAC landscape mean our crews here spend as much time addressing biological growth and condensation issues as they do ordinary dust buildup. Call us at (361) 326-5060 for a free estimate.
Why Clermont Homes Are Different
Clermont sits on the Lake Wales Ridge, and that elevated, lake-dotted terrain traps humidity against homes in ways flatter inland areas don’t experience. Average summer humidity stays above 70%, so AC systems run nearly year-round here. That constant moisture exposure creates ideal conditions for mold and mildew inside ductwork, especially in unconditioned attics where duct temperatures swing dramatically between the afternoon heat and overnight cooling.
The housing stock splits roughly in two. Mature lakeside cottages, many dating to the mid-20th century, often still have original metal ducts with loose joints that leak conditioned air straight into attic heat. Post-2000 subdivisions, meanwhile, were built with flex duct runs common to Florida construction. Those flex lines can harbor condensation and mold if insulation was skimped or compromised. After a week of Clermont’s typical afternoon thunderstorms, our techs regularly find water stains around ceiling vents in two-story homes. That’s duct condensation dripping onto drywall, a signature issue in newer, tightly built houses where moisture has nowhere to escape.
Homeowners here frequently call us not because they see dust, but because they smell something musty when the heat pump switches to heating mode for the first cool snap. That odor is biological growth waking up, and it’s one of the most common triggers for service calls in Clermont.
Our Main Clermont Services
Clermont homeowners reach out to us most often for these three jobs. Each has its own page with detailed pricing, process, and local considerations.
Air Duct Cleaning in Clermont
We clean supply and return ductwork with a Rotobrush rotary brush system that agitates debris off duct walls, paired with a Nikro negative-air machine that pulls loosened material out of the house entirely. In Clermont, we pay particular attention to flex duct insulation condition, since the humidity here can saturate fiberglass lining and turn it into a mold substrate. Every job gets before-and-after photos of your own ducts, not stock images. Air Duct Cleaning in Clermont

Dryer Vent Cleaning in Clermont
Lint buildup in dryer vents is a fire hazard everywhere, but in Clermont’s humidity, that lint can also hold moisture against the duct and accelerate corrosion of galvanized venting. We run a rotary brush through the full vent line to the exterior cap and measure airflow before and after. Most Clermont jobs take 45 – 90 minutes. Dryer Vent Cleaning in Clermont

Duct Sealing in Clermont
Leaky ducts in Clermont attics waste cooled air into 140-degree summer spaces and pull humid outside air back into the system. We seal accessible joints with mastic and metal tape, then pressure-test to verify the improvement. In older Clermont homes with original metal ductwork, this single job often drops energy bills more than equipment upgrades would. Duct Sealing in Clermont
