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.

AfterFast, Reliable Duct Sealing Across Zephyrhills
We’re the crew Hollis Air Duct Cleaning sends when Zephyrhills homeowners call about musty air, uneven cooling, or energy bills that climb every summer. Dispatch runs through our Miami office, but our techs live in the area and know the difference between a 1990s manufactured home off Chancey Road and a ranch near Zephyr Park. We arrive inside the quoted window, price the job in writing before we touch anything, and back every seal with our 365-Day Done Right Promise. Call (361) 326-5060 for a free estimate.
Why Hollis Air Duct Cleaning Is Zephyrhills’s Preferred Duct Sealing Company
We’ve been sealing ducts in Pasco County since 2004, and Zephyrhills accounts for a big share of our calls. The Garrison Standard means we don’t compete on teaser coupons; we compete on showing up, pricing it straight, and leaving the site clean. Our technicians are background-checked and uniformed, and you’ll know who’s arriving before they knock.
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 when your underbelly duct is leaking water into the insulation.
Every job gets a written price before work starts. That price does not move at the door. If the seal fails within a year, we come back and make it right at no charge, including a free second visit. That’s the 365-Day Done Right Promise, backed in writing on every invoice.
We know Zephyrhills’s housing stock: manufactured homes from the 1980s through the 2000s, RV park models, and older site-built ranches with ductwork buried in floor cavities and underbelly spaces. Our equipment includes Rotobrush rotary brush systems and Nikro negative-air machines, the same tools commercial crews use, explained in plain terms on every job.
Air Duct Sealing in Zephyrhills
Air Duct Sealing in Zephyrhills means closing the gaps, separations, and punctures in your ductwork so the air you paid to cool actually reaches your rooms instead of leaking into your attic, crawlspace, or manufactured-home underbelly. In this market, we see two distinct jobs: sealing accessible metal trunk lines in site-built homes, and repairing flexible duct runs in manufactured homes and RV park models where flooding, rodent damage, and sagging have compromised the connections. A typical Air Duct Sealing job in Zephyrhills runs $350 – $850 for standard residential work; manufactured homes with underbelly access issues or flood damage start around $500 and can reach $1,200 if extraction and disinfection are needed first.
When Sealing Comes After Extraction
Because Zephyrhills’ manufactured-home and RV park-model underbelly ducts sit above a high water table in sandy soil, sections routinely flood after heavy summer storms. Sealing over standing water or mold growth traps moisture and feeds microbial problems. We extract and disinfect first, then seal. That’s the sequence that lasts.
Verifying the Seal
After we apply mastic and mesh to compromised connections, we verify with a blower motor amp draw and negative pressure check. The system has to hold. We document the before and after readings on your invoice so you have proof the job was done, not just promised.
Duct Sealing Services in Zephyrhills
Duct Sealing Services in Zephyrhills cover everything from spot repairs on separated flex runs to full-system mastic sealing of metal trunk and branch lines. We use professional-grade duct sealing mastic, not hardware-store tape that dries and fails within a season. For manufactured homes with rodent intrusion in the underbelly, our Duct Sealing Services include rodent-proofing the repaired sections with metal mesh barriers before sealing, so the fix outlasts the next pest season. Duct Sealing Services in Zephyrhills typically range from $350 for straightforward spot work to $1,200 for manufactured homes requiring extraction, disinfection, rodent-proofing, and full resealing of multiple compromised runs.
Mobile Home and RV Park Model Specialists
Flexible duct in belly boards is a different animal from rigid metal. It sags. It punctures. Rodents chew it. Our techs carry the right mastic, mesh, and reinforcement straps for these systems, and we know how to access them without tearing apart your skirting.
Outbuilding and Secondary Systems
Zephyrhills properties with workshops, guest cottages, or converted outbuildings often have separate duct runs fed from the main handler. We seal those too, and we check whether they’re pulling return air from unconditioned spaces, which wastes energy and invites humidity.

Trusted Brands We Service in Zephyrhills
We stock parts and filtration products from Honeywell, Aprilaire, and Guardsman, so Zephyrhills customers aren’t waiting on a Miami warehouse shipment for standard repairs. Our equipment roster includes Rotobrush rotary brush systems for mechanical cleaning and Nikro negative-air machines for extraction jobs. When we seal your ducts, we use the same mastic and mesh products commercial HVAC contractors specify, not the tape you’ll find on the shelf at the hardware store on Gall Boulevard. Fast turnaround matters here because once a Zephyrhills underbelly duct floods in July, every day of delay means more microbial growth.
Common Duct Sealing Problems We See in Zephyrhills Homes
- Flooded underbelly ducts after summer storms. Zephyrhills’ sandy soil and high water table mean heavy rain floods manufactured-home belly cavities fast. We extract standing water and disinfect before sealing; sealing over moisture traps mold inside the run.
- Rodent-chewed flex duct in mobile home parks. Mice and rats access underbelly runs through gaps in skirting or foundation vents. We rodent-proof with metal mesh, then seal with mastic; tape alone fails when the next pest arrives.
- Sagging flex runs causing separations at collars. Age and humidity weaken the straps holding flexible duct in manufactured homes. We re-support and seal, or replace collapsed sections when re-support isn’t enough.
- Unpaved road dust and pollen clogging masked leaks. Rural Zephyrhills properties on dirt roads see heavy particulate loading that fills registers and filters, hiding duct leaks that sealing was supposed to fix. We clean the system first, then seal, so you know the real problem is solved.
Pricing for Duct Sealing in Zephyrhills, FL
A typical duct sealing job in Zephyrhills runs $350 – $850 for site-built homes with accessible metal ductwork. Manufactured homes and RV park models with underbelly access issues, flood damage, or rodent intrusion start around $500 and can reach $1,200 when extraction, disinfection, and rodent-proofing are required before sealing. What moves the price: the number of compromised runs, whether we can access them without removing skirting or decking, the extent of water or mold damage, and whether the system needs mechanical cleaning before sealing. We give you one flat price per system, agreed in writing before any work starts. No per-vent pricing, no add-ons at the door. Call (361) 326-5060 for a free estimate; we’ll inspect the system and quote it on the spot.

FAQs About Duct Sealing in Zephyrhills
Every 5 to 7 years for rural Zephyrhills manufactured homes, or sooner if you notice uneven cooling, musty odors when the AC runs, or visible black soot around vents. Unpaved road dust and heavy spring pollen accelerate wear on flex duct connections. Call (361) 326-5060 and we’ll inspect for free.
Sometimes, but not always. Black soot in Zephyrhills is usually mold and dust mixed with humidity, and it often signals a flooded or leaking underbelly duct pulling contaminated air. Sealing alone won’t fix it if the duct still holds standing water or mold; we extract and disinfect first, then seal. Call (361) 326-5060 for a camera inspection.
Yes. We seal RV park model underbelly ducts and outbuilding systems fed from main handlers. These jobs often require rodent-proofing and re-supporting sagging flex runs before sealing. We price by the system, not by the vent, and we quote in writing before starting. Call (361) 326-5060 to schedule.
Every 3 to 4 years for Zephyrhills homes running AC year-round, and every 2 to 3 years for manufactured homes on rural lots with unpaved road exposure. Year-round cooling keeps ducts damp, which accelerates microbial growth; rural properties see extra dust loading that clogs returns and masks leaks. Call (361) 326-5060 for a free assessment of whether cleaning or sealing should come first.
Because manufactured-home underbelly ducts in Zephyrhills sit in accessible cavities that mice and rats routinely enter through gaps in skirting or foundation vents. Sealing with mastic and mesh over chewed flex duct without a metal barrier means the next pest season destroys your repair. Our Duct Sealing crews rodent-proof first, then seal, so the fix lasts. Call (361) 326-5060 for an estimate.
We were called to a 1987 manufactured home on Dean Dairy Road where the homeowner complained of a musty smell only when the AC ran; our tech ran a camera inspection of the underbelly supply and return ducts, found a flooded flex run with standing water and mold growth, extracted and disinfected it, then sealed the compromised connections with mastic and mesh. After sealing, we verified with a blower motor amp draw and negative pressure check that the system held, and the odor cleared within a day.
