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 Sunrise Manor
We dispatch our crews to Sunrise Manor from our Las Vegas office, and we’re familiar with the neighborhood grid from Nellis Boulevard out to Charleston and Lamb. Most calls we get here aren’t from new construction. They’re from homeowners in 1970s and 1980s ranch homes who’ve had their ducts cleaned before, noticed a brief improvement, then watched the dust return within a month or two. That’s usually not a cleaning problem. It’s a sealing problem. If you’re seeing the same fine silt on your furniture after a service, or your back bedroom never cools evenly, the air isn’t moving through the ducts the way it was designed to. Call us at (361) 326-5060 and we’ll inspect the full system, price the sealing work in writing, and show you exactly where the air is escaping.

HVAC Duct Sealing in Sunrise Manor
HVAC Duct Sealing in Sunrise Manor is typically needed when homeowners notice uneven cooling, rising utility bills, or dust that reappears too quickly after a cleaning service. The job involves accessing the duct runs in attic or crawl spaces, inspecting every joint and seam with a camera, then applying professional-grade mastic sealant to close gaps where conditioned air escapes into unconditioned spaces. In Sunrise Manor’s market, a standard residential duct sealing job runs $450 – $850 for a single system, with larger homes or dual-system setups (rooftop package unit plus evaporative cooler) ranging $750 – $1,400. We always write the price down before work begins, and that number does not move at the door.
What We Find in Sunrise Manor Attics
The original mastic on 1970s rigid sheet metal ducts has been baking in Mojave attic heat for forty or fifty years. It doesn’t fail all at once. It hairlines, then spiderwebs, then flakes off entirely. By the time a homeowner calls us, the average system is leaking 20 – 30% of its conditioned air into the attic. We map every leak with a pressure test, then seal accessible joints with fresh mastic rated for the temperature swings these attics see.
Dual-System Complications
Many Sunrise Manor homes run both a rooftop package unit for summer cooling and an evaporative cooler for shoulder-season relief. These share ductwork, which means sealant has to survive both 105°F+ dry heat and monsoon-driven moisture. We use products from Abatement Technologies and Guardsman formulated for exactly this cycle, not the hardware-store caulk some crews carry.
Duct Repair in Sunrise Manor
Duct Repair in Sunrise Manor goes beyond sealing when we find crushed, disconnected, or deteriorated runs that no amount of mastic can fix. This is common in the older housing stock here. Original flex duct gets crinkled by decades of attic traffic. Sheet metal collars separate. A previous homeowner or handyman may have “fixed” a leak with foil tape that peeled off in the first summer. Duct repair in this market typically runs $300 – $600 for localized fixes (single crushed run, reconnection, collar replacement) and $800 – $1,500 when multiple runs need rebuilding or replacement. We photograph the damage, explain the options, and write the repair price before we cut or replace anything.
Disconnected Runs and Hot Rooms
The back bedroom that never cools is often a disconnected supply run, not a failing air conditioner. We camera the line to confirm, then reconnect and seal properly. On a 1972 ranch near Charleston and Nellis, our tech pulled crinkled original flex off a return run in the hallway and found crushed collars and a disconnected supply to the back bedroom. Using a camera inspection and Rotobrush agitation tools, we performed source removal under negative pressure, re-connected the run, and sealed every accessible joint in the attic with mastic; the homeowner noticed the back room finally cooled within minutes.
Monsoon Damage to Evaporative Cooler Ducts
After a July or August storm, evaporative cooler ducts can fill with wet, muddy dust that hardens into cakes. This masks underlying damage. We’ve opened ducts that looked merely dirty and found separated seams, rusted metal, or collapsed flex underneath the mud. We clean first, then repair, then seal. Doing it in that order prevents sealing over trapped moisture that would breed mold.
Trusted Brands We Service in Sunrise Manor
We stock parts and sealant products from Aprilaire, Abatement Technologies, and Guardsman, which means most Sunrise Manor repairs don’t wait on a parts run to a warehouse across town. Our equipment roster includes Rotobrush rotary brush systems for source removal and Nikro negative-air machines for contained cleaning. When we’re sealing ducts that connect to a rooftop package unit or swamp cooler, we use sealants rated for the temperature extremes and moisture cycles these systems see. That matters because a seal that holds in a mild climate may fail in a Sunrise Manor attic that swings from 40°F winter nights to 140°F summer afternoons.
Common Duct Sealing Problems We See in Sunrise Manor Homes
- Original mastic joints dry-cracked from decades of attic heat. The 1970s mastic on rigid sheet metal turns brittle and flakes off. A standard duct cleaning removes dust but leaves these leaks wide open, so the system pulls attic air back in within weeks.
- Evaporative cooler ducts cake with monsoon mud that hides disconnections. After July – September storms, wet silt hardens on metal duct walls. It looks like dirt. Underneath, we often find crushed runs or separated collars that need repair before sealing.
- Leaky return ducts pull desert silt past the filter. When return lines have gaps near a rooftop package unit, they draw in fine Mojave dust and attic debris that overwhelms a standard MERV 8 filter. The air handler and supply ducts re-coat within weeks of cleaning.
- Previous “repairs” with foil tape or spray foam that failed. We’ve peeled off hardware-store solutions that lasted one summer. Proper mastic application, done with the duct dry and clean, outlasts these shortcuts by decades.
Pricing for Duct Sealing in Sunrise Manor, NV
A typical duct sealing job in Sunrise Manor runs $450 – $850 for a single HVAC system in a ranch or low-rise home under 2,500 square feet. Homes with both a rooftop package unit and an evaporative cooler, or larger properties with extensive attic duct networks, generally fall in the $750 – $1,400 range. Duct repair, when needed alongside sealing, adds $300 – $600 for localized fixes or $800 – $1,500 for multiple run replacements. What moves the price: accessibility of attic ductwork, extent of original mastic failure, whether evaporative cooler ducts need pre-cleaning of monsoon caking, and if camera inspection reveals disconnected or crushed runs requiring repair before sealing. We inspect first, photograph what we find, and write the full price on paper before any sealant is opened. Estimates are free. Call (361) 326-5060 to schedule.

FAQs About Duct Sealing in Sunrise Manor
Monsoon moisture from July through September swells and weakens sealant that wasn’t rated for wet-dry cycling, and it washes new silt into gaps that were barely sealed rather than properly repaired. We use sealants formulated for Mojave moisture swings and always clean and dry ducts before sealing, which prevents the trapped moisture that causes premature failure. If you’ve had a seal fail within a year of service, call (361) 326-5060; our 365-Day Done Right Promise covers the rework at no charge.
Most 1960s – 1990s sheet metal in Sunrise Manor can be sealed and remain serviceable for another decade or more if the metal itself isn’t rusted through or structurally collapsed. We camera-inspect to confirm the metal condition before recommending anything beyond sealing. Replacement becomes necessary when we find rust holes, multiple crushed runs, or disconnected sections that can’t be rejoined.
We pressure-test both duct systems, camera all accessible runs, clean evaporative cooler ducts of any monsoon caking, then seal every accessible joint with mastic rated for dual-system temperature and moisture exposure. The written price covers the full scope before we begin, with no per-vent add-ons or trip charges.
Uneven cooling between rooms, a sudden drop in airflow from one register, or dust that returns within two to three weeks of cleaning all point to disconnection or crushing rather than surface contamination. We confirm with camera inspection, show you the footage, and explain whether sealing alone will solve it or if repair is needed first. Call (361) 326-5060 for an exact diagnosis; estimates are free.
Yes, if the silt is entering through leaky return ducts near the rooftop package unit or through gaps in the evaporative cooler ductwork. Sealing those pathways stops the suction of unfiltered attic and outdoor air. It does not stop silt that enters through open windows or doors, which is why we identify the source before we quote so you know what sealing will and won’t fix.
