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 Bermuda Dunes
Your ducts are leaking. In Bermuda Dunes, that means cooled air escaping into your attic while your AC runs overtime against 110-degree Coachella Valley heat. Duct sealing in Bermuda Dunes typically runs $450 – $1,200 for a whole-home seal, and most jobs finish in a single visit. Call (361) 326-5060 for a free written estimate.
We’ve worked on homes along Washington Street, in the Bermuda Dunes Country Club area, and throughout the neighborhoods near Fred Waring Drive. Our crews dispatch from the Inland Empire office and serve Bermuda Dunes directly. We know the ranch-style homes built in the 1970s with rigid metal ducts that have never been touched, and we know the Mediterranean-style retirement properties near the golf course with flex duct that squirrels have chewed through. That local familiarity means we spot problems faster and fix them right the first time.
Why Hollis Air Duct Cleaning Is Bermuda Dunes’s Preferred Duct Sealing Company
Bermuda Dunes homeowners call us back because we show up inside the window, price the job in writing before we touch anything, and leave the site clean. That’s The Garrison Standard, and it’s how every Hollis crew operates.
Our technicians are background-checked and uniformed. You’ll know who’s arriving before they pull into your driveway. Phones are answered by a live person 24 hours a day, 7 days a week, no voicemail loops, no callback queues.
The 365-Day Done Right Promise covers every duct sealing job we do in Bermuda Dunes. If the seal fails within a year, we return and make it right at no charge, including a free second visit. That promise is backed in writing on every invoice, not something we mention verbally and forget.
We understand how Bermuda Dunes homes age. The single-family detached houses built from the 1960s through the 1990s, many originally second homes or retirement properties, often have ductwork that hasn’t been inspected in decades. Our Duct Sealing team knows where to look for the leaks that develop in these systems.
Air Duct Sealing in Bermuda Dunes
Air Duct Sealing in Bermuda Dunes means finding and closing every gap, joint separation, and corrosion hole in your forced-air system so cooled air reaches your rooms instead of your crawl space. In this desert resort community, where central AC runs nearly year-round and the surrounding Coachella Valley’s dust storms force systems to work harder, leaking ducts can add 20 – 30% to your cooling bill. Most Bermuda Dunes homeowners need sealing when they notice hot rooms, excessive dust, or utility bills that climb despite thermostat settings staying flat. A typical whole-home seal in Bermuda Dunes runs $450 – $1,200 depending on system accessibility and leak severity.
How We Find the Leaks
We pressurize your duct system and use a calibrated fan to measure airflow loss, then trace escaping air with smoke pencils and thermal imaging. In Bermuda Dunes homes near the country club, we often find original metal ductwork with separated seams that have been leaking since the Reagan administration.
What We Seal With
We use duct sealing mastic, a thick water-based compound that brushes onto joints and hardens into a permanent flexible seal, plus metal-backed tape rated for high temperatures. For larger gaps in older Bermuda Dunes systems, we may install custom-cut sheet metal patches before sealing. This isn’t hardware-store foil tape that peels off in the attic heat.
Duct Sealing Services in Bermuda Dunes
Duct Sealing Services in Bermuda Dunes address the specific failures that desert climate and aging housing stock produce here. The extreme heat, constant AC operation, and fine sand infiltration from surrounding dunes stress duct joints and connections year after year. When we seal a system in Bermuda Dunes, we’re not just stopping air loss, we’re preventing that fine desert silt from being pulled into gaps and recirculated through your home. A typical residential job runs $450 – $1,200, with larger homes or systems requiring attic crawl work toward the higher end.
Evaporative Cooler Conversion Sealing
Parts of Bermuda Dunes share a high water table with the broader Coachella Valley, and homes that once ran evaporative coolers often have mineral dust and scale buildup in ducts. When we seal these systems, we first remove that residue so the mastic bonds to clean metal, not to crumbling calcium deposits.

Return Air Path Repair
Many Bermuda Dunes homes have return air pathways that were never properly sealed during original construction, pulling hot attic air directly into the system. We close those pathways and verify with pressure testing so your AC breathes only conditioned indoor air.

Trusted Brands We Service in Bermuda Dunes
Our equipment comes from Rotobrush, Nikro, and Abatement Technologies, the same brands commercial HVAC crews specify. We stock sealing mastics, metal-backed tapes, and replacement duct sections locally so Bermuda Dunes customers aren’t waiting on parts from Los Angeles. For filtration upgrades after sealing, we carry Honeywell and Aprilaire products. That local inventory means when we find a separated main trunk on a home near Adams Street, we can fix it that visit instead of scheduling a return trip.
Common Duct Sealing Problems We See in Bermuda Dunes Homes
- Santa Ana wind sand infiltration. After major spring wind events, we find fine silt packed into duct joints and around register boots. The grit accelerates corrosion and prevents tape adhesion, so we clean before we seal.
- Original 1970s metal duct with separated longitudinal seams. These rigid ducts were built to last, but the locking seams weren’t designed for fifty years of thermal expansion in 110-degree attics. We re-crimp and mastic-seam them.
- Flex duct crushed by homeowners storing holiday decorations. In Bermuda Dunes homes with attic storage, we regularly find flex duct flattened in sections, creating turbulence and leaks at the crimp points. We replace damaged sections and reroute where possible.
- Evaporative cooler residue blocking seal adhesion. The mineral dust left by decades of swamp cooler use in parts of Bermuda Dunes acts like a powder barrier. Our crews scrape and solvent-clean before applying mastic so the seal actually holds.
Pricing for Duct Sealing in Bermuda Dunes, CA
A typical whole-home duct sealing in Bermuda Dunes runs $450 – $1,200. Smaller homes with accessible ductwork and minor joint separation fall at the lower end. Larger homes, systems requiring attic crawl space navigation, or extensive corrosion repair push toward the higher end. We do not price per vent or per linear foot. You get one flat price per system, agreed in writing before any work starts.
What affects your specific cost: how many leaks we find during pressure testing, whether duct sections need replacement versus sealing only, and attic accessibility. Homes near the Bermuda Dunes Country Club with original 1960s ductwork often need more extensive repair than 1990s construction near the newer developments off Fred Waring Drive.
Every estimate is free. We’ll pressure-test your system, show you the leak locations, and write the price on the invoice before we begin. Call (361) 326-5060 to schedule.

Yes, we work throughout Bermuda Dunes including the Bermuda Dunes Country Club area, homes along Washington Street, and neighborhoods near Fred Waring Drive and Adams Street. The housing stock varies by area, ranch-style 1970s homes near the golf course versus 1990s construction closer to the commercial corridor, and we adjust our approach accordingly.
We do not classify duct sealing as an emergency service, but we prioritize appointments for homeowners whose AC has failed or whose indoor air quality has degraded sharply, such as after a major sandstorm. Phones are answered by a live person 24/7, and we’ll get you scheduled as quickly as possible.
Bermuda Dunes pricing falls in line with Coachella Valley rates, typically $450 – $1,200 for whole-home sealing.

Where we differ is in pricing structure: one flat price per system, written before work starts, with no per-vent add-ons that inflate the final bill.
Every duct sealing job is covered by our 365-Day Done Right Promise. If the seal fails within one year, Hollis returns and makes it right at no charge, including a free second visit. That promise is printed on your invoice, not a verbal assurance. For exact terms on your specific job, call (361) 326-5060 and we’ll walk through the written guarantee before you book.
