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 New Port Richey
Duct sealing in New Port Richey typically costs $350 – $850 for a whole-home system, and most jobs are completed in a single visit. If your HVAC runs constantly but rooms stay uneven, or your energy bills climb through the humid summer months, the problem is often air leaking from ducts before it ever reaches your vents. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we’ve been sealing ducts in New Port Richey’s coastal neighborhoods since 2004. Our dispatch team operates from our Miami office, but our crews serve New Port Richey directly – no out-of-town delays, no crews who don’t know the local housing stock. Call (361) 326-5060 for a free written estimate.
Why Hollis Air Duct Cleaning Is New Port Richey’s Preferred Duct Sealing Company
We’ve worked in the block ranchers off U.S. 19, the manufactured home communities near the river, and the stucco subdivisions inland toward Ridge Road. That range matters. A tech who only knows one housing type will miss the failure modes that define New Port Richey ductwork.

Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. Phones are answered by a live person 24 hours a day, seven days a week. No voicemail loops. No callback queues.
Duct Sealing Services in New Port Richey
Duct Sealing Services in New Port Richey focus on closing the gaps, disconnected joints, and crushed runs that let conditioned air escape into attics, crawl spaces, and wall cavities. In this market, the work is rarely about installing new ductwork. It’s about reconnecting what’s already there and sealing it properly so your system stops working against itself. A typical whole-home duct sealing job in New Port Richey runs $350 – $850, depending on the number of runs, accessibility, and whether we find storm or pest damage that needs repair before sealing.
Most New Port Richey homeowners call us after noticing hot or cold spots, musty odors when the system runs, or energy bills that spike during the summer humidity marathon. Others schedule sealing after a duct cleaning reveals that dust isn’t the problem – the ducts themselves are pulling unconditioned air from the wrong places.
Leak Detection and Pressure Testing
We start with a pressure test to measure how much air your system is losing before it reaches your vents. In New Port Richey’s older homes, we regularly see 20 – 30% loss through disconnected collars, failed mastic, and crushed flex runs. The test gives us a baseline and shows you exactly where the money is going.
Mastic Sealing and Collar Reconnection
We seal joints, plenums, and connections with duct mastic – a water-based sealant that flexes with temperature changes and holds up in humid conditions. Tape alone fails in New Port Richey’s climate. Mastic doesn’t. We reconnect detached runs and replace crushed flex where needed, then verify the repair with a second pressure test.

Duct Insulation in New Port Richey
Duct Insulation in New Port Richey addresses a separate problem from sealing: thermal loss through duct walls, especially in garage- and closet-mounted air handlers where unconditioned air surrounds the ductwork. Even perfectly sealed ducts will sweat and lose efficiency if the insulation is thin, torn, or missing. In New Port Richey’s climate, where outdoor dew points stay high eight months of the year, sweating ducts are a constant threat. A typical duct insulation job in New Port Richey runs $400 – $950 for a whole system, depending on linear footage and whether we’re wrapping existing ducts or replacing degraded insulation.
Homeowners near the Gulf, especially in older neighborhoods with air handlers in exterior closets or garages, often need both sealing and insulation. The combination stops air loss and thermal transfer at the same time.
R-Value Upgrades for Humid Climates
We install insulation rated for Florida’s humidity, not the dry-climate products you’ll find at hardware stores. Proper R-value means your cold supply air stays cold until it reaches the vent, instead of warming up in a hot attic and forcing your compressor to run longer.
Condensation Control
Sweating ducts damage ceilings, breed microbial growth, and reduce system lifespan. In New Port Richey’s near-constant summer humidity, we see this most in homes with original insulation from the 1970s or 1980s. We remove degraded material, treat the duct surface, and install vapor-barrier-wrapped insulation that handles the dew point difference between your attic and your conditioned air.
Trusted Brands We Service in New Port Richey
We carry professional-grade equipment and materials from Rotobrush, Aprilaire, Abatement Technologies, and Guardsman – the same brands commercial HVAC crews use, not retail-grade substitutes. For New Port Richey homeowners, that means we stock mastic, insulation, and collar fittings locally, so we’re not waiting on a parts run while your system sits open. Our rotary brush systems and negative-air machines are built for the accumulation and humidity conditions we find in Pasco County’s coastal housing. When we seal your ducts, we do it with materials that are rated for this climate and this workload.
Common Duct Sealing Problems We See in New Port Richey Homes
- Disconnected or crushed flex runs at the air handler. In the older coastal blocks and manufactured homes near the Pithlachascotee River, we find flex duct that has been patched after tropical storms or compromised by rodent intrusion from the sandy soil. The runs look intact from outside, but they’re pulling river-marsh air straight into the living space.
- Sealant failure and chronic condensation. New Port Richey’s humidity keeps duct interiors damp year-round, and mastic applied in dry conditions rarely cures out completely here. We remove failed sealant and reapply with products formulated for high-dew-point environments.
- Undersized returns in 1960s – 1980s block ranchers. The original duct layout wasn’t designed for today’s continuous runtime. Sealing helps, but sometimes the real fix is adding return capacity so the system can breathe. We’ll tell you which problem you actually have.
- Sealing over microbial growth without cleaning first. This is the shortcut that costs homeowners twice. If ducts aren’t cleaned to NADCA standards before sealing, trapped moisture and mold recur within a season. We inspect with cameras before we seal.

FAQs About Duct Sealing in New Port Richey
New Port Richey’s coastal location brings salt air, higher sustained humidity, and tropical storm exposure that inland markets don’t face. Ducts here stay damp, mastic degrades faster, and wind-driven rain can force water into attic and closet-mounted air handlers. Sealing is preventive maintenance in this climate, not an occasional repair. Call (361) 326-5060 for a free inspection.
Yes, if the smell is coming from duct leaks pulling in outside air. In the neighborhoods near the Pithlachascotee River, we regularly find disconnected collars and crushed flex runs that are drawing musty air directly into the system. Our field team sealed exactly this problem in a 1970s block rancher where rodent intrusion from the sandy soil had compromised two connections at the air handler. Reconnecting and sealing with mastic eliminated the odor within a day. Call (361) 326-5060 – we’ll camera-inspect to confirm the source before quoting.
Short flex runs, often original or patched after storms, with disconnected collars at the plenum and air handler. Undersized returns are common. The sandy soil in this area means rodent and insect intrusion through crawl space vents or damaged foundation screens. We also see sealant that has failed from decades of humidity exposure. A camera inspection under negative pressure tells us exactly what’s happening inside your specific system. Call (361) 326-5060 to book one.
Sealing stops unconditioned humid air from entering the system, which reduces the moisture load that feeds mold. But sealing alone won’t fix condensation on duct exteriors. For that, you need proper insulation with a vapor barrier, especially on supply ducts in hot attics or garage-mounted air handlers. In New Port Richey’s climate, we often recommend both. Call (361) 326-5060 and we’ll assess whether your problem is air leakage, thermal loss, or both.
Sealing closes gaps and joints so conditioned air reaches your vents instead of leaking into walls or attics. Insulation wraps the duct exterior so the air stays at temperature and the duct surface doesn’t sweat in humid conditions. In New Port Richey’s coastal homes, especially older ones with air handlers in exterior closets or garages, both problems usually exist together. We can do either separately, but the lasting fix is often both. Call (361) 326-5060 for a written estimate on the combination.
