AfterLennox Air Duct Cleaning in Las Vegas, CA | Hollis Air Duct Cleaning
Air Duct Cleaning in Las Vegas for your Lennox system typically runs $350 – $650 for a full system, and we complete most jobs in a single visit. We’re an independent shop, not a Lennox-authorized dealer, and we service every Lennox model family across the valley. The difference here is simple: we know how Lennox ductwork behaves when it bakes in a 140°F attic for six months straight. Call (361) 326-5060 for a written quote before any work starts.
Why Las Vegas Residents Choose Us for Lennox Service
Roy Castellanos runs Hollis Air Duct Cleaning, and he grew up in Boyle Heights before spending years in the mechanical trades across Los Angeles County. He learned HVAC fundamentals through the sheet metal and air conditioning program at Los Angeles Trade-Technical College, then put in years of hands-on duct work before starting this company. That background matters when a Lennox system in Las Vegas is underperforming because the return chase is packed with caliche dust and the flex runs have collapsed in attic heat.
We’ve pulled, sealed, and repaired thousands of feet of Lennox ductwork across the Las Vegas valley, from 1990s Summerlin tract homes to 1970s Huntridge ranches. As an independent shop, we answer to the homeowner, not to a manufacturer’s program. That means we stock OEM-equivalent Lennox flex-duct, mastic, and coil-cleaning chemicals, and we use genuine Lennox replacement parts only when the model calls for them, like iComfort sensors or specific coil sizes. Every job gets a written price before work begins, and every job is covered by the 365-Day Done Right Promise. If the work fails within a year, we come back at no charge. That’s the Garrison Standard, and we don’t waver from it. For more on our Lennox coverage, see our Lennox sales & service page.
Common Lennox Air Duct Cleaning Problems We Solve in Las Vegas
- Sagging flex-duct runs in 140°F+ attics. Lennox systems installed in Summerlin and Henderson during the 1990s – 2010s commonly used flexible duct in attic spaces. After enough Mojave summers, the inner liner softens, sags between trusses, and chokes airflow. The system runs longer, the rooms stay warm, and the compressor takes a beating. We replace the crushed runs with insulated flex and mastic-seal the connections.
- Caliche dust caking the evaporator coil. July through September, monsoon winds push fine PM10 dust through return-air chases across Las Vegas. On Lennox systems, that dust lands on the evaporator coil and drops static pressure across the air handler. We see airflow drop 15 – 25% within days of a big dust storm. Cleaning the return and coil restores it.
- Formicary corrosion on Lennox aluminum evaporator coils. Low desert humidity combined with dust at the coil face creates the exact conditions for formicary corrosion, especially on Lennox coils running hard from July through September. Pinpoint leaks show up as slow refrigerant loss. We flag it during duct cleaning so you don’t discover it in August.
- Undersized metal duct in older Downtown and Huntridge homes. Original 1950s – 70s metal duct was often sized for 3-ton equipment. When a homeowner retrofits a 4 – 5 ton Lennox condenser onto that old duct, the return starves the system and the compressor runs hot. We measure static pressure and tell you plainly if the duct is the bottleneck.
- Collapsed return chases in master-planned communities. In Las Vegas tract homes from the 2000s, return chases built with drywall and framing can pull apart at the seams. Dust and attic air get sucked in, bypass the filter, and coat the coil. We seal those chases and clean the return path so the air actually goes through the filter.
Lennox Service in Las Vegas: What Local Conditions Mean for Your Equipment
Las Vegas runs roughly 300 sunny days a year with summer highs routinely above 105°F. A Lennox system here cycles more hours than in nearly any other U.S. metro. That changes the math on duct cleaning entirely. In a humid city, a dirty return duct means slightly dusty air. In Las Vegas, a dust-clogged return or a sagging flex run shows up as a measurable cooling-capacity loss within days, not months. The July – September monsoon winds that drive caliche dust into return-air chases make duct cleaning an efficiency job here, not just a dust job.
Techs who work this valley for years know the “Summerlin filter effect.” After a July dust storm, whole neighborhoods see AC airflow drop because return ducts pull in fine caliche dust that cakes the evaporator coil. That doesn’t happen in humid, less windy cities. In a 2003 Summerlin tract home off Town Center Drive, we opened a Lennox Signature SL280V air handler after the homeowner reported the second floor never cooling below 82°F. The return chase was packed with caliche dust from a July monsoon, and two flex-duct runs in the attic had collapsed against the trusses. We cleaned the return and evaporator coil, replaced the crushed flex with insulated runs, and mastic-sealed the plenum. The system pulled 18°F across the coil on the next visit. That’s the kind of result that only comes from knowing how Lennox equipment behaves under Mojave conditions. Clean ducts, straight answers – that’s the whole job.
Lennox Models & Products We Service in Las Vegas
We work on the full Lennox lineup, and we know which models show up most often in Las Vegas homes. The Dave Lennox Signature Collection (SL280V, SL297NV) appears in higher-end Summerlin and Henderson builds, usually paired with iComfort-enabled controls. The Elite Series (EL296V, EL18XCV) covers a wide swath of mid-2000s tract homes. The Merit Series (ML14XC1, ML180) is common in newer developments and rental conversions. Older Lennox CompleteHeat systems, which combined heating and hot water in one chassis, still turn up in 1990s homes across the valley.
On 15-plus year-old Lennox systems with failed coils or crushed flex runs, we price out honest repair versus a Lennox or comparable-brand replacement. No upsells, no scare tactics. You get the numbers, and you decide. Our full coverage area is listed on the Las Vegas service area page.
Lennox Service Pricing in Las Vegas
Here’s what Lennox air duct cleaning actually costs in Las Vegas right now. Whole-home duct cleaning on a typical 2,000 – 2,800 square foot valley home runs $350 – $650. That includes the full supply and return duct network, the plenum, and the air handler cabinet. Adding evaporator coil cleaning runs $150 – $350 depending on coil access and condition. Flex duct repair or replacement runs $12 – $18 per linear foot, which includes the insulated duct, mastic, and hangers. Return chase sealing, which we recommend on most pre-2010 Las Vegas tract homes, runs $200 – $500 depending on how far gone the chase is. Commercial systems or homes over 3,500 square feet run higher, and we quote those after a walkthrough.

FAQs – Lennox Air Duct Cleaning in Las Vegas
Las Vegas homes run their Lennox systems harder and longer than almost any other metro, with roughly 300 sunny days a year and summer highs routinely above 105°F. Add the July – September monsoon winds that blow fine caliche dust into return-air chases, and your ducts accumulate debris at a rate you simply don’t see in humid or less windy cities. Most Las Vegas homeowners with a Lennox system should have ducts inspected every 2 – 3 years, and cleaned when airflow or dust levels justify it. Call (361) 326-5060 for a free assessment, and we’ll tell you honestly if cleaning is worth it right now.
Yes, and it’s one of the most common issues we find in Summerlin and Henderson homes built between 1990 and 2015. Flexible duct installed in attic spaces softens under sustained 140°F heat, and over time the inner liner sags or collapses between trusses. That chokes airflow to the rooms furthest from the air handler. On a Lennox system, the result is longer runtimes, uneven cooling, and extra strain on the compressor. We replace collapsed runs with properly supported insulated flex and seal every connection with mastic as part of our Dryer Vent Cleaning in Las Vegas service.
Directly, yes. In Las Vegas, the dust that clogs your coil comes through the ducts. Caliche dust from monsoon winds gets pulled through the return path and lands on the coil face, where it drops static pressure and cuts cooling capacity. If we clean the ducts but skip the coil, you’ve only solved half the problem. We clean both together, and on Lennox systems with formicary corrosion risk, we inspect the coil carefully during the process. Call (361) 326-5060 for a quote that covers the full return-to-coil path.
The tell is when a newer, larger Lennox condenser gets paired with original 1950s – 70s metal duct. Those ducts were often sized for 3-ton equipment, and a 4 – 5 ton Lennox condenser needs more return air than the old duct can deliver. You’ll notice weak airflow at the registers, a system that runs constantly on hot days, and higher utility bills. We measure static pressure across the system and tell you plainly if the duct is starving the equipment. Some older metal duct can be sealed and retained; some should be replaced. You’ll get the numbers either way.
No. Hollis Air Duct Cleaning is an independent service provider, not a Lennox-authorized dealer or manufacturer-affiliated shop. That independence means we recommend what’s right for your system, not what a manufacturer program requires us to sell. We use OEM-equivalent flex-duct, mastic, and coil-cleaning chemicals, and we use genuine Lennox replacement parts only when the model calls for them, like iComfort sensors or specific coil sizes. You get straight answers, not a sales pitch.
