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 Air Duct Cleaning Across Clermont
Air duct cleaning in Clermont typically runs $350 – $650 for a full residential system, with most jobs completed in a single visit. We dispatch crews to Clermont from our South Florida coordination office, and we’ve worked in enough homes from the older lakeside cottages near Lake Minneola to the newer subdivisions off Highway 27 to know what hides in this city’s ductwork. Call us at (361) 326-5060 for a free estimate with a written price before any work starts.
Clermont’s humid subtropical climate keeps AC systems running nearly year-round, and that constant moisture exposure creates conditions you won’t find in drier parts of the state. Our Air Duct Cleaning team has cleared biological growth from flex duct that sagged in unconditioned attics, sealed loose joints in original metal ductwork from the 1970s, and traced water stains around ceiling vents back to condensation issues that homeowners assumed were roof leaks. We don’t guess. We inspect first, price in writing, then clean and seal by the book.

We serve Clermont and the surrounding Lake County area from our South Florida dispatch office, with crews that understand local building patterns: the flex duct common in post-2000 construction, the original metal runs in lakeside cottages, and the humidity-driven failure modes that show up differently here than inland.
Ductwork Cleaning in Clermont
Ductwork Cleaning in Clermont starts with understanding what kind of ductwork you actually have. In this city, that varies dramatically by neighborhood and era of construction. Mature lakeside cottages and post-2000 subdivisions dominate Clermont’s housing stock, and they fail in nearly opposite ways.
In the newer homes, flex duct runs common in Florida construction can harbor condensation and mold if not properly insulated. The material sags over time, creating low spots where moisture collects. A surface wipe at the register never reaches that growth. In older homes, original metal ducts with loose joints leak conditioned air into the attic heat, wasting energy and pulling humid attic air back into the system. Cleaning without Duct Sealing in Clermont just re-leaks air and moisture into the attic.
A typical residential Ductwork Cleaning in Clermont runs $350 – $550 for a standard system, with larger homes or heavily contaminated systems reaching $650. Commercial systems are priced by square footage and complexity.
Rotary Brush and Negative-Air Methods
We match the method to the duct material. For metal ductwork, our Rotobrush rotary brush system scrubs the interior walls while a Nikro negative-air machine maintains suction, pulling dislodged debris out of your home rather than pushing it into your living space. For flex duct, we reduce agitation intensity to avoid tearing the material, relying more on controlled negative pressure and soft-bristle contact.
Sealing After Cleaning
Cleaning disconnected or crushed duct runs without sealing them is incomplete work. We inspect every joint with a camera after agitation, then seal gaps with mastic, a thick, flexible compound that remains airtight through Florida’s temperature swings. The price for sealing is included in your written quote if we identify leaks during inspection.
Air Duct Inspection in Clermont
Air Duct Inspection in Clermont is where we earn the trust of homeowners who’ve been burned by bait-and-switch pricing before. We run a video camera through your supply and return lines before quoting any cleaning work. You see what we see: disconnected joints, crushed flex runs, biological growth, or decades of accumulation in original metal ductwork.
This inspection matters especially in Clermont because of how local conditions accelerate specific failures. Average summer humidity above 70% keeps systems running constantly, and that moisture exposure creates ideal conditions for mold and mildew inside ductwork. In unconditioned attics, duct temperatures swing dramatically between the cooled air inside and the attic heat outside, causing expansion and contraction that loosens joints over years.
An Air Duct Inspection in Clermont typically costs $150 – $250, which is credited toward your cleaning if you proceed with the work. The inspection takes 45 – 60 minutes, and you’ll receive video documentation of what we found.
What We Document
Our technicians record footage of every accessible duct run, noting material type, condition of joints, evidence of moisture intrusion, and any biological growth. We mark timestamped locations so you can reference specific problem areas. This documentation becomes part of your written quote, with each recommended service line-itemed.
When to Schedule an Inspection
Call for an inspection if you notice musty odors when switching from cooling to heating, uneven temperatures between rooms, visible dust accumulation around vents, or water stains on ceiling drywall. In Clermont, we also recommend inspection before purchasing older lakeside homes, where original ductwork may have decades of unaddressed accumulation.
Trusted Brands We Service in Clermont
Our equipment roster includes Rotobrush rotary brush systems and Nikro negative-air machines for the mechanical cleaning work, plus filtration products from Honeywell, Aprilaire, and Guardsman. These are the same tools commercial crews use, not hardware-store gear. We stock common filtration components locally for Clermont customers, so if your inspection reveals that your return grille filters are undersized or your media cabinet needs an upgrade, we can often complete that work during the same visit rather than ordering parts and rescheduling.
Common Air Duct Cleaning Problems We See in Clermont Homes
- Musty odors when heat first kicks on. In Clermont’s older lakeside cottages, duct cleaning calls spike in the first cold snap – not because of visible dust, but because heat-pump systems that have been cooling all year suddenly blow a musty odor through original metal ducts with loose joints, sending attic-heat leaks and mold spores into living rooms.
- Flex duct sagging and condensation in newer subdivisions. Post-2000 homes with flex duct runs in unconditioned attics often develop sagging low points where condensation pools. The insulation wrapping degrades, and mold establishes in the core where no register wipe can reach.
- Water stains around ceiling vents after storms. After a week of afternoon thunderstorms, techs often find water stains around ceiling vents in Clermont’s two-story homes – a sign that duct condensation is dripping onto the drywall, a common issue in the area’s newer, tightly built houses. Homeowners frequently misdiagnose this as a roof leak.
- Disconnected joints wasting energy and pulling in attic air. Original metal ducts in older Clermont homes develop loose joints from years of attic heat swings. The system works harder, energy bills climb, and the air you breathe mixes with whatever is in your attic. Cleaning without sealing just re-leaks air and moisture into the attic.

FAQs About Air Duct Cleaning in Clermont
That odor usually comes from biological growth in your ductwork that has been dormant or slow-growing during cooling season, then gets reactivated and distributed when the heat pump switches to heating mode. In Clermont’s humid climate, with systems running nearly year-round, moisture accumulates in duct low points and on loose joint surfaces. When heated air flows through, it releases those musty compounds into your living space. We were called to a 1970s cottage near Lake Minneola after the homeowner noticed exactly this smell. Our tech ran a camera inspection and found the original metal supply and return ducts had disconnected at a joint above the air handler, dumping conditioned air into the humid attic. We used negative pressure and agitation tools to remove decades of biological growth, then sealed the joint with mastic – the odor was gone and static pressure dropped enough to ease strain on the blower motor. Call (361) 326-5060 if you’re experiencing this; an inspection will pinpoint the source.
Most Clermont homes benefit from professional duct cleaning every 3 – 5 years, though homes with older metal ductwork, visible mold history, or residents with respiratory sensitivities may need service every 2 – 3 years. The humid subtropical climate here, with average summer humidity above 70%, accelerates biological growth compared to drier regions. If you’ve never had your ducts inspected and your home was built before 2000, we recommend starting with a camera inspection to establish a baseline condition. Call (361) 326-5060 to schedule.
Probably not. After a week of afternoon thunderstorms, techs often find water stains around ceiling vents in Clermont’s two-story homes – a sign that duct condensation is dripping onto the drywall, a common issue in the area’s newer, tightly built houses. The temperature differential between your cooled duct air and the humid attic air causes moisture to form on the duct exterior, then drip at the vent penetration point. A roof leak would typically show staining farther from the vent center or in multiple locations unrelated to duct runs. Our inspection can confirm the source with a camera check of the surrounding ductwork and attic conditions. Call (361) 326-5060 for an inspection.
Yes. A complete residential cleaning addresses both supply ducts (which deliver conditioned air to your rooms) and return ducts (which pull air back to the air handler). In Clermont, return ducts often show heavier accumulation because they’re pulling unfiltered air from your living space, while supply ducts may show more biological growth if moisture is entering from loose joints. We inspect and clean both systems, and we verify airflow balance after sealing any leaks. The written quote itemizes what is included so you know exactly what you’re paying for. Call (361) 326-5060 for details.
We use professional-grade Rotobrush rotary brush systems and Nikro negative-air machines for the cleaning work itself, plus filtration products from Honeywell, Aprilaire, and Guardsman for any component upgrades. These are the same tools commercial crews use, not hardware-store gear. We explain what each piece does and why we’re using it on your specific duct material before we start. If your inspection reveals that your return grille filters are undersized or your media cabinet needs an upgrade, we can often complete that work during the same visit. Call (361) 326-5060 with questions about our equipment or to schedule an inspection.
