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 Sun Village
Duct sealing in Sun Village typically costs $850 – $2,400 for a whole-home job on a single-story ranch, and most projects are completed in one day. We’re the Sun Village crew from Hollis Air Duct Cleaning, and we know the older stucco homes here – the ones built in the 1950s and 1960s on large lots off the main roads – because we’ve been inside enough of them to recognize the patterns. Dispatch and scheduling run through our Los Angeles office, but our technicians live and work in the Antelope Valley, so we’re not driving three hours to reach you. Call (361) 326-5060 for a free estimate.

We’ve built our reputation in Sun Village on showing up inside the window, pricing in writing before we touch anything, and leaving the site clean. That’s The Garrison Standard, and it’s how every Hollis location operates.
Our technicians are background-checked and uniformed – you know who’s walking into your home before they arrive.

No negotiation, no runaround.
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 for a scheduling question.
We know Sun Village’s housing stock – the post-war ranch homes with original or minimally retrofitted ductwork, the evaporative coolers on roofs, the well water that leaves mineral scale in humidifier lines. That local knowledge means we diagnose faster and quote accurately the first time.
Duct Sealing Services in Sun Village
Duct Sealing Services in Sun Village start with understanding what you’re actually breathing. Our Duct Sealing team doesn’t just chase leaks – we identify why the leaks formed and what’s sitting inside the duct before we seal anything closed.
A typical whole-home duct sealing job in Sun Village runs $850 – $2,400, depending on accessible linear footage, the condition of existing mastic, and whether we find disconnected or crushed runs that need reconnection or replacement. We price by the system, not by the vent. The price is written down before any work starts, and it does not move at the door.
Most Sun Village homeowners call us when rooms stay hot despite the AC running, when dust blows from registers after cleaning, or when the evaporative cooler season ends and grit keeps circulating. These are symptoms of leaky supply and return ducts pulling unfiltered air from attics, crawl spaces, and wall cavities.
Leak Detection and Mastic Sealing
We pressurize the duct system and use a calibrated fan to measure total leakage against the conditioned floor area. Leaks get sealed with duct mastic – a water-based sealant that flexes with temperature swings better than tape alone. In Sun Village’s 100°F summers, that flexibility matters. Mastic stays put when foil tape dries and curls.
Disconnected Run Reconnection
In older Sun Village ranches, we regularly find supply runs that have separated behind knee walls or in attic spaces where original supports failed. We reconnect, support, and seal these runs so conditioned air reaches the back bedroom that never cooled properly.

Duct Insulation in Sun Village
Duct Insulation in Sun Village addresses a problem most homeowners don’t know they have: attic ductwork losing 20 – 30% of its cooling capacity to 140°F attic air before it ever reaches the register. In a climate where summer highs routinely exceed 100°F and HVAC systems run almost year-round, that’s wasted money every hour the blower spins.
A typical duct insulation job in Sun Village runs $1,200 – $3,000 for a full attic system, depending on linear footage, existing insulation condition, and accessibility. We use professional-grade materials from Honeywell and Abatement Technologies – not the hardware-store wrap that compresses and loses R-value within a season.
Most Sun Village homes need insulation when the original fiberglass wrap has degraded, when rodents have disturbed attic runs, or when a new air handler is pushing more CFM than the old system and the ducts sweat condensation into the attic. Sweating ducts rot ceiling drywall and grow mold. Insulation stops both.
R-Value Assessment and Upgrade
We measure existing insulation depth and condition, then quote an R-8 or R-11 upgrade where the original R-4 or R-6 has compressed or degraded. In Sun Village’s arid heat, higher R-value means the 55°F air from your coil arrives at 53°F instead of 62°F.
Vapor Barrier Repair
Original duct insulation in 1950s Sun Village homes often lacks an intact vapor barrier. We install new wrap with a sealed facing that prevents attic dust from adhering to wet duct surfaces and stops mineral-laden condensation from wicking into the fiberglass.
Trusted Brands We Service in Sun Village
We stock parts and materials from Honeywell, Aprilaire, and Abatement Technologies for Sun Village jobs – no waiting on a warehouse run to Los Angeles while your attic sits open. We also offer our Dryer Vent Cleaning in Sun Village using the same professional approach. Our Nikro negative-air machines and Rotobrush rotary systems are the same tools commercial crews use in hospitals and schools, and we bring them to your ranch home because your air matters as much as any institution’s. Fast turnaround means we diagnose, quote, and often complete sealing work same-day on standard Sun Village single-story layouts.
Common Duct Sealing Problems We See in Sun Village Homes
- Crushed runs behind knee walls. The original 1950s flex duct was thin-walled and poorly supported. Decades of attic traffic or storage compression collapse the airway. Sealing the ends doesn’t fix it – the run has to be reconnected or resized for modern static pressure.
- Mineral grit caked along seams. Sun Village’s well water and evaporative coolers leave a scale-and-dust film inside ducts. Seal over that grit and the mastic bonds to dust, not metal. It fails within a season. We remove the source first, then seal.
- Undersized supply runs for new air handlers. Original ductwork was sized for 3-ton blowers, not the 4- or 5-ton units homeowners install to fight Mojave heat. Sealing can’t overcome choked static pressure – we resize the critical runs or the system short-cycles forever.
- Wind-driven infiltration through return leaks. High desert winds pull fine soil into attic return plenums through gaps around filter racks and platform seams. The HVAC system becomes a dust pump. We seal the return side as carefully as the supply side.
Pricing for Duct Sealing in Sun Village, CA
Whole-home duct sealing in Sun Village typically runs $850 – $2,400. Duct insulation runs $1,200 – $3,000. What moves you within that range: accessible linear footage (crawl space versus slab-on-grade with attic-only access), whether we find disconnected runs needing reconnection, and if the job requires source removal of mineral grit before sealing can begin.
We do not quote per-vent pricing. That’s the bait-and-switch game – a low per-vent teaser that balloons once the technician is inside. Hollis gives one flat price per system, agreed in writing before work starts. The price on the paper is the price at completion.

FAQs About Duct Sealing in Sun Village
Sun Village’s combination of 100°F-plus summers, high-wind desert soil infiltration, and evaporative cooler mineral scale means leaky ducts pull far more unfiltered, abrasive particulate into your system than in a coastal climate where mild temperatures and ocean air keep ducts cleaner. Sealing here is source protection, not just efficiency. Call (361) 326-5060 for a free estimate.
Yes, most 1950s Sun Village ranch ductwork can be sealed effectively after source removal of accumulated grit and scale, though we sometimes find crushed or disconnected runs that need reconnection or resizing for modern air handlers. We inspect with a camera before quoting so you know exactly what needs sealing versus replacement. Call (361) 326-5060 for a free estimate.
Yes – evaporative coolers introduce mineral-laden moisture into ducts that standard forced-air systems never see, leaving scale that prevents mastic from bonding properly. We clean and dry affected sections before sealing, and we check whether the cooler supply is properly isolated from the furnace return to prevent cross-contamination. Call (361) 326-5060 for a free estimate.
If rooms stay unevenly heated or cooled after cleaning, if dust returns within weeks, or if your blower short-cycles, you likely have leaks that cleaning alone won’t fix. We measure duct leakage with a calibrated fan test – 15% or more of total airflow leaking outside conditioned space means sealing will pay for itself in efficiency and air quality. Call (361) 326-5060 for a free estimate.
We pressurize the system to locate leaks, remove mineral grit and scale from seams, seal all accessible joints with duct mastic, reconnect any separated runs, and retest to verify leakage reduction. On a typical 1,200-square-foot Sun Village ranch, the job takes four to six hours. Call (361) 326-5060 for a free estimate.
