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 Duct Sealing Across Brooksville
Duct sealing in Brooksville typically runs $450 – $1,200 for a whole-home system, with most single-family homes falling in the $550 – $850 range. We dispatch crews from our South Florida scheduling office and serve Brooksville homeowners with the same written pricing and 365-Day Done Right Promise we’ve operated under since 2004. If your ducts are leaking conditioned air into your attic, crawl space, or behind walls, you’re paying to cool or heat air that never reaches your living space, and in Brooksville’s humid subtropical climate, those leaks also pull in moisture that feeds mold growth inside your system.
We’re familiar with the ductwork quirks that show up across Brooksville’s neighborhoods. In Timber Pines, we regularly find flexible ductwork that’s been chewed through by rodents during the summer months when snowbird homes sit empty. Around historic downtown Brooksville, the 1920s bungalows with retrofit central air often have undersized supply runs that were never properly sealed at the boot connections. Out toward Hernando Beach and the Spring Lake area, manufactured homes from the 1990s frequently have sagging flex duct that’s pulled away from the plenum. These aren’t hypothetical scenarios. They’re what our technicians encounter on Brooksville jobs week after week.
Call (361) 326-5060 to schedule a free estimate. We’ll inspect your duct system, show you exactly where the leaks are with a smoke test or thermal camera, and give you a written price before any work starts.
Why Hollis Air Duct Cleaning Is Brooksville’s Preferred Duct Sealing Company
We’ve built our reputation in Brooksville on showing up when we said we would and pricing the job in writing before we touch anything. That shouldn’t be unusual in this trade, but it is. Homeowners in Brooksville tell us they’ve had other duct companies quote one price over the phone and present a bill 40% higher once the crew is inside. We don’t operate that way. The Garrison Standard requires the price to be written down and agreed to before work begins, and our Brooksville customers get the same guarantee.
Our technicians are background-checked and uniformed, and you’ll know who’s arriving before they knock. We use professional-grade equipment from Rotobrush and Nikro, the same negative-air machines and rotary brush systems that commercial crews rely on, and we explain what we’re doing in plain terms while we work. If you’re in Timber Pines, Hernando Beach, or the historic district near Main Street, we’ve likely sealed ducts on your street or the next one over.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops, no callback queues, no waiting until Monday to get on the schedule.
Every duct sealing job we complete in Brooksville is backed by our 365-Day Done Right Promise. If the seal fails, the leak returns, or you’re not satisfied with the result, we come back and make it right at no charge, including a free second visit if needed. That’s in writing on every job, not a verbal assurance that disappears when the van leaves your driveway.
Duct Repair in Brooksville
Duct Repair in Brooksville covers the physical fixes that go beyond sealing: replacing torn flexible ductwork, reattaching collapsed runs, repairing rusted metal plenums, and addressing damage from pests or water intrusion. Most Brooksville homeowners need duct repair when they can feel weak airflow from certain vents, hear whistling or rattling from the attic, or notice one room stays 5 – 10 degrees warmer than the rest despite the AC running constantly. In this market, duct repair typically runs $300 – $800 depending on how many runs need replacement and whether we need to access a crawl space or attic.
Flexible Duct Replacement
Brooksville’s housing stock includes thousands of homes built between 1980 and 2005 with original flexible ductwork that has become brittle, torn, or detached at the collars. We remove the damaged runs and install new insulated flex duct with proper support straps and sealed connections. In manufactured homes near Hernando Beach, we often find flex duct that’s sagged and kinked, choking airflow to the back bedrooms.
Metal Duct Patching and Plenum Repair
Older homes in Brooksville’s historic district sometimes have galvanized metal ductwork that’s rusted through at the seams or developed holes from condensation pooling. We cut out the damaged section and weld or mechanically fasten a replacement piece, then seal with mastic rated for high-velocity systems. This is more durable than tape repairs that fail within a season or two in our humidity.
Air Duct Sealing in Brooksville
Air Duct Sealing in Brooksville is the process of closing gaps, cracks, and disconnected joints in your duct system so conditioned air reaches your rooms instead of leaking into your attic, crawl space, or wall cavities. We use duct sealing mastic, a thick, fiber-reinforced compound that remains flexible after curing, applied with brushes and professional tools to ensure complete coverage at every joint and seam. A typical whole-home sealing job in Brooksville runs $550 – $850 for a single-family home up to 2,500 square feet, with larger homes or systems with extensive damage running toward the higher end.
Mastic Sealing at Joints and Boots
Every connection point in your duct system, where a branch line meets the main trunk or where the duct attaches to the vent boot in your ceiling or wall, is a potential leak. We apply mastic to these joints after cleaning the surface, creating a permanent seal that won’t dry out and crack like foil tape does after a few Brooksville summers. In homes near Spring Lake, we’ve found that original construction seals on 1990s-era homes have almost completely failed, with gaps large enough to slide a pencil through.
Smoke Testing and Thermal Verification
Before we seal, we pressurize your duct system and use a smoke pencil or thermal imaging camera to locate every leak, including the ones hidden behind insulation or in inaccessible corners of your attic. After sealing, we test again to verify the improvement. Brooksville homeowners typically see a 15 – 25% reduction in their cooling runtime after proper duct sealing, which matters when your AC runs eight months a year.
Trusted Brands We Service in Brooksville
Our Brooksville crews carry professional-grade equipment and materials from Rotobrush, Nikro, and Guardsman on every van. Rotobrush rotary brush systems let us clean and prep duct surfaces before sealing so the mastic bonds properly instead of adhering to dust and debris. Nikro negative-air machines maintain proper containment during the process, and Guardsman filtration products help us protect your home’s air quality while we work. We stock common duct diameters, boot sizes, and mastic compounds locally so we’re not waiting on parts shipments that delay your job. Whether your system uses standard 6-inch flex duct or an older metal configuration, we have the fittings and expertise to seal it correctly the first time.
Common Duct Sealing Problems We See in Brooksville Homes
- Snowbird duct deterioration in Timber Pines and Hernando Beach. Homes that sit closed up for 6 – 8 months while Canadian owners are up north develop leaks where rodents have chewed through duct insulation and where temperature cycling has loosened tape seals. When owners return in November and blast the heat for the first time, they smell musty air and notice weak flow to the master bedroom.
- Humidity-driven mastic failure in 1980s – 2000s single-family homes. Brooksville’s hot, rainy summers create attic temperatures above 130°F and relative humidity that stays elevated for months. Original duct seals applied with inferior tape or thin mastic dry out, crack, and separate. We remove the old material and apply fresh, fiber-reinforced mastic rated for our climate.
- Undersized and unsealed retrofit ducts in historic downtown bungalows. The 1920s – 1950s homes near Main Street and Broad Street weren’t built for central air, and the retrofit ductwork installed decades ago often has gaps at the plenum connection where the new system meets old construction. These leaks pull in attic air that’s 30 degrees hotter than your living space in July.
- Manufactured home flex duct collapse near Spring Lake. Mobile and manufactured homes in Brooksville frequently use thin, poorly supported flex duct that sags between joists, creating low points where condensation collects and where the duct eventually tears away from the collar. We replace with properly supported, insulated runs and seal every connection with mastic.
Pricing for Duct Sealing in Brooksville, FL
A typical whole-home duct sealing in Brooksville runs $550 – $850 for a single-family home up to 2,500 square feet. Larger homes or those with multiple HVAC systems range from $900 – $1,200. Partial sealing of a specific problem zone, such as a leaking return plenum or a disconnected branch line, typically falls in the $300 – $500 range.
What moves the price: accessibility of your ductwork (crawl space vs. walk-in attic), the condition of existing seals (removing failed tape adds labor), whether we need to repair or replace damaged duct sections before sealing, and the number of HVAC zones in your home. We do not charge per vent or per linear foot. We price by the system, in writing, before we start.
Every estimate is free. We’ll inspect your ducts, identify the leaks, and give you a flat price with no obligation. Call (361) 326-5060 to schedule.
