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 Zephyrhills South
We’re the crew that handles Duct Sealing for homeowners from Crystal Springs Road down to the manufactured-home communities off Chancey Road. Our dispatch team operates from our South Florida office, and we’ve got technicians running routes through Pasco County regularly. That means when you call (361) 326-5060, you’re talking to a live person who knows where Zephyrhills South sits relative to the SR-39 corridor, not a call center guessing at Florida geography. We’ve sealed ducts in the block-built ranches near the Zephyrhills Municipal Airport and in the crossover systems under manufactured homes off Eiland Boulevard. The housing stock here is specific, the climate is specific, and the way ductwork fails after twenty-plus years of Florida humidity is specific. We know what to look for because we’ve already looked.
Why Hollis Air Duct Cleaning Is Zephyrhills South’s Preferred Duct Sealing Company
Our reputation in Zephyrhills South was built one written estimate at a time. Homeowners here talk, especially in the tighter-knit communities off Morris Bridge Road, and we’ve found that doing what we said we’d do earns more calls than any coupon ever could. The 365-Day Done Right Promise backs every seal we apply. If a mastic joint fails or a flex-duct connection opens up within a year, we come back and make it right at no charge, including a free second visit if needed.
Response time to Zephyrhills South typically falls within our standard Pasco County routing window. We don’t promise impossible dispatch speeds, but we do promise you’ll know exactly when we’re arriving, and our background-checked, uniformed technicians will show up inside that window. Roy Castellanos built this operation on The Garrison Standard: arrive when you said, price it before you touch it, leave the site clean. That’s the code our crews live by in Zephyrhills South and everywhere else we serve.
Air Duct Sealing in Zephyrhills South
Air Duct Sealing in Zephyrhills South means closing the gaps, cracks, and separated joints that let your conditioned air leak into attics, crawl spaces, and wall cavities before it ever reaches your rooms. In this market, we typically see whole-home duct sealing running $850 – $1,400 for site-built homes with accessible attic ductwork, and $450 – $750 for manufactured homes needing crossover duct repairs and main trunk sealing. The price is written down before we start, and it doesn’t move at the door.
What the Job Actually Involves
We pressurize the system to locate leaks, then seal with mastic compound and reinforced mesh at joints, connections, and penetrations. For Zephyrhills South’s aging flex-duct runs, we often find the inner liner has separated from the insulation jacket, especially near plenum connections where attic heat has degraded the adhesive over two decades.
When Sealing Beats Replacement
Not every leaky duct needs tearing out. If your metal trunk lines are sound and the flex runs show localized failure, targeted sealing restores efficiency without the cost of full replacement. We’ll tell you straight which path makes sense after we inspect.
Duct Sealing Services in Zephyrhills South
Duct Sealing Services in Zephyrhills South cover everything from spot repairs after lightning damage to whole-system sealing for homes with utility bills that keep climbing despite the thermostat never moving. Our crews carry professional-grade mastic, foil tape rated for Florida attic temperatures, and replacement flex duct in standard diameters so most jobs finish in a single visit. Typical pricing for partial system sealing starts around $350, with full-home sealing in the $850 – $1,400 range depending on accessibility and the extent of deterioration.
Post-Storm Damage Assessment
After a lightning strike in the Crystal Springs area, we often get calls about burning smells and dead air handlers. The hidden damage frequently extends to ductwork in wall cavities, and our technicians are trained to locate and seal these runs without unnecessary drywall demolition.

Manufactured-Home Crossover Specialists
The crossover ducts under Zephyrhills South’s manufactured homes take a beating from ground moisture and pest intrusion. We seal and wrap these vulnerable runs with materials that hold up to Florida’s wet seasons, not the hardware-store tape that peels off in six months.

Trusted Brands We Service in Zephyrhills South
We stock sealing materials and filtration components from Aprilaire, Abatement Technologies, and Guardsman, plus we carry Rotobrush rotary systems for jobs where duct cleaning precedes sealing. For Zephyrhills South homeowners, this means no waiting on parts shipments from Atlanta or Dallas. If your system needs a specific collar, boot, or mastic type, we’ve likely got it on the van. Our technicians train on the same equipment commercial crews use in hospitals and schools, and we bring that standard to your laundry room and attic. When we recommend a product by name, it’s because we’ve watched it hold up through Florida’s brutal attic heat cycles, not because a distributor offered us a spiff.
Common Duct Sealing Problems We See in Zephyrhills South Homes
- Failed flex-duct insulation in 1990s block homes. The original flex runs in neighborhoods off Chancey Road and Eiland Boulevard have hit or exceeded their 20-year lifespan. The outer vapor barrier cracks, the fiberglass sags, and the inner liner pulls away from collars, dumping conditioned air into the attic.
- Lightning-induced damage in wall cavities. Zephyrhills South’s position in Lightning Alley means nearby strikes can surge through grounding systems and damage air handlers, sometimes blowing joints apart in duct runs hidden behind drywall. We locate these with pressure testing and seal them with minimal intrusion.
- Crossover duct separation under manufactured homes. The ductwork bridging the two halves of a double-wide sits close to the ground in Zephyrhills South’s sandy, sometimes wet soil. Tapes degrade, seams open, and suddenly half the house won’t cool. We seal with mastic and mechanical fasteners, then wrap for moisture protection.
- High humidity degrading attic mastic. Florida’s year-round cooling demand keeps attics hot and humid. Original builder-grade sealing compounds dry out and flake away. Our resealing uses products rated for sustained 180°F exposure, which matters when your attic hits 140°F in August.
Pricing for Duct Sealing in Zephyrhills South, FL
Whole-home duct sealing in Zephyrhills South typically runs $850 – $1,400 for site-built homes with attic-accessible ductwork. Manufactured-home crossover and main trunk sealing usually falls between $450 – $750. Spot repairs for isolated leaks or post-storm damage start around $350. What moves the number: how much of the system is accessible without cutting drywall, whether flex duct needs replacement versus just reconnection, and how many return air pathways need sealing. We don’t quote per-vent or per-linear-foot teaser prices that balloon once we’re inside. One flat price per system, agreed in writing before work starts. Call (361) 326-5060 for a free estimate. We’ll inspect, explain what we found, and give you a written number you can compare without pressure.
