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 Air Duct Cleaning Across Moreno Valley
Air duct cleaning for a typical Moreno Valley home runs $350 – $650 for a full system, and our crews are usually on-site within a few days of your call. We’re the local Air Duct Cleaning team serving Moreno Valley from our Inland Empire dispatch office, not a call center three states away. Roy Castellanos and our crew know the difference between a 1985 Sunnymead Ranch tract home with original flex duct and a newer two-story build in the east end with complex attic runs. That matters because the problems we find, and what it takes to fix them, are not the same. Call (361) 326-5060 for a free estimate with a written price before any work starts.
Why Hollis Air Duct Cleaning Is Moreno Valley’s Preferred Air Duct Cleaning Company
We’ve been in business since 2004 as part of the Garrison Partners family, and our reputation in Moreno Valley is built on showing up inside the window, pricing in writing, and leaving the site clean. That’s The Garrison Standard. Our technicians are background-checked and uniformed, and our phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues.
Moreno Valley homeowners call us because they’ve been burned before: a low teaser price that doubled once the van was in the driveway, a crew that scattered dust through the living room and left, or a “cleaning” that was 20 minutes with a shop vacuum. We do not work that way. The price is written down before any work starts, and it does not move at the door. Every job is covered by our 365-Day Done Right Promise: if the work fails within a year, we come back and make it right at no charge, including a free second visit.
We know the local roads, the neighborhoods, and the housing stock. Dispatch and scheduling are coordinated from our Inland Empire office, but crews serve Moreno Valley locally. That means we understand why calls spike after a Santa Ana wind event, and we know what to look for in the original flex duct that still runs through thousands of local homes.
Commercial Air Duct Cleaning in Moreno Valley
Commercial Air Duct Cleaning in Moreno Valley covers office buildings, retail spaces, medical clinics, and multi-unit properties where code compliance, employee health, and HVAC efficiency are on the line. The job involves source-removal of accumulated debris from supply and return ductwork using negative-air machines and rotary brush agitation, with HEPA filtration to contain what we pull out. A typical commercial system in Moreno Valley runs $800 – $2,500 depending on square footage, duct complexity, and access. Most commercial clients schedule every 2 – 3 years, or after renovation work.
Code Compliance and Documentation
Moreno Valley commercial properties often need post-cleaning documentation for insurance, property management, or municipal requirements. We provide written scope-of-work summaries and before/after photo documentation from our video inspection system. The price for that documentation is included in the written quote, not added later.
After-Hours and Weekend Scheduling
We schedule commercial work to avoid disrupting your operations. Our crew can run negative-air equipment overnight or through a Saturday without shutting down your business. The Garrison Code requires us to arrive squared away, work quietly, and leave no trace beyond cleaner air.
Air Duct Cleaning Services in Moreno Valley
Air Duct Cleaning Services in Moreno Valley start with a camera inspection of your supply and return ducts, followed by source-removal using either a rotary brush system or negative-air method depending on duct type and contamination level. A typical residential full-system cleaning in Moreno Valley runs $350 – $650, with older homes needing additional sealing work sometimes pushing toward $800 – $1,200 if we find disconnected or crushed flex duct. We clean what we can access, report what we cannot, and never charge for work you did not approve in writing.
Supply Duct and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the air handler. In Moreno Valley’s 1980s – 2000s tract homes, we often find return ducts loaded with Santa Ana dust and supply boots leaking into the attic. We clean both sides and seal what we find. No per-vent pricing, no surprises.

Video Inspection and Duct Sealing
Our camera shows you the inside of your ducts before and after. In many Moreno Valley homes, the real problem is not dirt but breaks: sagging flex duct, disconnected boots, or crushed runs dumping conditioned air into the attic. We can seal those with mastic and mechanical fasteners, often improving efficiency more than cleaning alone.

Trusted Brands We Service in Moreno Valley
We run professional-grade equipment, not hardware-store gear. Our rotary brush systems come from Rotobrush, our negative-air machines from Nikro, and our filtration products from Honeywell, Aprilaire, and Abatement Technologies. For duct sealing and protection, we use Guardsman products where appropriate. We stock common fittings and filtration media so Moreno Valley customers are not waiting on parts. When your system needs a specific component, we source it fast and install it right. The brands matter because they determine what we can actually remove from your ducts and what we can keep out afterward.
Common Air Duct Cleaning Problems We See in Moreno Valley Homes
- Sagging original flex duct. The 1980s – 2000s boom built thousands of Moreno Valley homes with cheap flex duct that collapses in attic heat over 20 – 30 years. We regularly find runs sagging below the insulation line, collecting debris and restricting airflow.
- Disconnected or crushed supply boots. After a fall Santa Ana event, our crew pulled up to a 1994 two-story in Moreno Valley Ranch where the upstairs registers were puffing visible dust; camera inspection showed a crushed flex run behind the air handler and a disconnected supply boot in the attic. We set up negative pressure with HEPA filtration, ran agitation tools through the supply and return ducts, and source-removed decades of accumulation, then reconnected and sealed the crushed run. The homeowner said the difference was immediate – no more dust clouds when the blower motor kicked on.
- Santa Ana dust and wildfire ash loading. Moreno Valley’s inland position – without the marine layer that settles dust in coastal Orange County or LA – means duct systems here load up with Santa Ana-blown desert dust and wildfire ash far faster, so a 1990s Sunnymead Ranch tract home can carry heavier particulate in its original flex duct than a similarly aged coastal home. That loading, plus 20-30 year old sagging flex duct, is why post-Santa Ana calls spike across Moreno Valley Ranch and Sunnymead Ranch.
- Undersized retrofitted ductwork near downtown. In the older ranch-style homes near downtown Moreno Valley, retrofitted ductwork runs undersized and leaky, letting attic condensation and dust mix into the supply side. Cleaning helps, but sealing and proper sizing are often the real fix.

FAQs About Air Duct Cleaning in Moreno Valley
Moreno Valley’s inland location means no marine layer to settle dust, so Santa Ana winds push fine desert particulate and wildfire ash directly into outdoor HVAC intakes. A typical Moreno Valley home accumulates heavier duct loading in 3 – 5 years than a coastal home does in 7 – 10. Call (361) 326-5060 for a free estimate – estimates are free.
We typically find sagging flex duct, dust-packed return plenums, and disconnected or crushed supply boots that dump conditioned air into the attic. The camera shows it clearly, and we explain what needs cleaning versus what needs sealing before any work starts. Call (361) 326-5060 for a free estimate – estimates are free.
Yes. We use source-removal methods consistent with NADCA guidelines: negative-air machines from Nikro to contain debris, rotary brush agitation from Rotobrush to dislodge buildup, and HEPA filtration to capture what we pull out. We explain the method to you on-site before we start. Call (361) 326-5060 for a free estimate – estimates are free.
Yes. Dryer vent cleaning is a separate service we can schedule the same day. It runs $120 – $200 for a typical Moreno Valley home, and we price it in writing before we touch it. A clogged dryer vent is a fire hazard, and combining the two services saves a trip charge. Call (361) 326-5060 for a free estimate – estimates are free.
Longer runs take more time and sometimes require additional access points, but the price is still flat per system, not per vent. We inspect the full layout with our camera and quote accordingly before any work starts. Two-story homes in Moreno Valley Ranch and east Moreno Valley often have complex attic runs that reveal surprises; we find them and fix them. Call (361) 326-5060 for a free estimate – estimates are free.
