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.

Call (361) 326-5060 for a free written estimate.
Colton’s older housing stock isn’t a footnote for us. It’s the main event. The 1950s-70s slab-floor tract homes in neighborhoods like Rancho West and the blocks south of the 10 were built with sheet-metal trunks and early flex branch runs sized for a lighter dust load than what the Cajon Pass delivers today. Santa Ana winds and prevailing westerlies funnel fine desert grit straight into return-air systems, and homes near the 215/10 interchange get a second layer of freeway brake particulate on top of that. Our Air Duct Cleaning team knows what to look for because we’ve cleaned hundreds of these systems. We don’t just vacuum the trunk and call it done.
Why Hollis Air Duct Cleaning Is Colton’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Colton on The Garrison Standard: arrive inside the quoted window, price in writing before any work starts, complete the job by the book, and leave the site clean. That standard is backed by our 365-Day Done Right Promise. If the work fails within a year, we return and make it right at no charge, including a free second visit.
Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. And when you call (361) 326-5060, a live person answers the phone 24 hours a day, 7 days a week. No voicemail loops. No callback queues. No waiting until Monday for a scheduling question.
We don’t compete on the lowest teaser price. We compete on discipline. The price we write down before work begins is the price you pay. No per-vent add-ons. No equipment charges that appear once the van is in your driveway. That approach matters in Colton, where working-class budgets don’t have room for moving targets.
HVAC Duct Cleaning in Colton
HVAC Duct Cleaning in Colton means more than removing visible dust from registers. It means addressing decades of accumulation in sheet-metal trunks and flex branch runs that were never designed for today’s particulate load, then verifying the system actually moves air where it’s supposed to go. A typical residential HVAC duct cleaning in Colton runs $350 – $550 for a single-story home with 10 – 15 registers, and $450 – $650 for larger two-story homes in the north and northeast developments with longer attic duct runs.
We clean under negative pressure using Nikro equipment and HEPA filtration, with rotary brush agitation for the stubborn grease-and-grit film that standard vacuuming won’t touch. Before we start, we run a video inspection so you see what we’re seeing. After we finish, we show you the before-and-after. The price is written and agreed before any tool enters your home.
Full System Cleaning
Full system cleaning covers supply ducts, return ducts, the plenum, and the trunk lines. In Colton’s pre-1980 homes, this often reveals crushed or disconnected branch runs that have been dumping conditioned air into wall cavities for years. We flag those issues during the video inspection and handle the reconnection and sealing as part of the job, priced separately if the repair is extensive.
Video Inspection
Our camera goes down every accessible run before and after cleaning. In east-side Colton homes near the 215/10 interchange, we’ve found flex duct collars crushed by decades of vibration, rodent damage in attic chases, and registers sealed with paint or caulk by previous owners. The camera removes the guesswork and gives you a record of what was actually in your system.
Vent Cleaning in Colton
Vent Cleaning in Colton targets the supply and return registers, the boot connections, and the first few feet of branch line where debris concentrates. A standard vent cleaning for a Colton home with 10 – 15 registers runs $180 – $320 as a standalone service, though most homeowners bundle it with full system cleaning for better value. The register itself is often the tip of the iceberg.
We remove each vent cover, clean the boot and visible ductwork, and treat the surrounding finish work with care. In Colton’s older homes, register screws are often painted over or corroded; we handle that without damaging your walls or ceilings. If the dark film on your east-side registers won’t wipe off with a cloth, it’s likely the greasy freeway-and-brake particulate that needs agitation and solvent cleaning, not surface wiping.
Supply Duct Cleaning
Supply ducts push conditioned air into your rooms. When they’re partially blocked by collapsed flex duct or decades of packed dust, you get weak airflow and hot spots on triple-digit afternoons. We clean with rotary brushes and negative-air extraction, then verify flow at each register.
Return Duct Cleaning
Return ducts pull air back to the HVAC unit. In Colton, these run especially dirty because they’re the entry point for Cajon Pass wind grit and, near the freeways, brake particulate. A clogged return forces your system to work harder, run longer, and filter less effectively. Cleaning the return often improves system performance more than cleaning supplies alone.
Trusted Brands We Service in Colton
Our equipment roster includes Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, and Abatement Technologies. These are the same tools commercial crews use, not hardware-store gear. We stock common replacement parts for Colton homeowners so we’re not ordering components and making you wait. If your system needs a filter upgrade after cleaning, we’ll recommend the right MERV rating for Colton’s dust load, not oversell you on filtration your blower can’t handle.
Common Air Duct Cleaning Problems We See in Colton Homes
- Dark, greasy register film near the 215/10 interchange. Homeowners assume it’s ordinary dust. It’s not. It’s brake particulate and freeway film that bonds to duct surfaces and needs agitation with rotary brushes and proper solvent cleaning, not a vacuum hose and a prayer.
- Disconnected or crushed flex branch runs in slab-floor homes south of the 10. These separations dump conditioned air into wall cavities and pull unfiltered make-up air from attics or crawl spaces. Vacuuming the trunk without fixing the branch leaves the real problem untouched.
- Sagging flex duct in 1990s-2000s north Colton two-stories. Long attic runs with inadequate support create low spots where dust and moisture collect, tearing the inner liner over time. We support and seal these runs during cleaning service.
- Dryer vent buildup in older homes with long or routed exhaust paths. The lint trap catches a fraction of the load. The rest packs into the duct, restricting airflow and creating a fire hazard. We clean the full run, not just the accessible sections.

FAQs About Air Duct Cleaning in Colton
They collect a greasy, bonded film of freeway brake particulate mixed with Cajon Pass wind grit that standard vacuuming won’t remove. We use rotary brush agitation and solvent cleaning to break that bond, then extract under negative pressure with HEPA filtration. Call (361) 326-5060 if your east-side registers show dark buildup that won’t wipe clean.
Yes. In Colton’s pre-1980 slab homes, we’ve found crushed or disconnected flex branch runs dumping conditioned air into wall cavities instead of rooms. We verify this with camera inspection, then reconnect and seal the source with mastic and foil tape. The cleaning follows. Call (361) 326-5060 for a video inspection and written estimate.
Yes. Our negative-air method, containment protocols, and agitation techniques meet NADCA guidelines for source removal. We use professional-grade Nikro and Rotobrush equipment, not shop vacs with jury-rigged hoses. The 365-Day Done Right Promise covers our work in writing.
Colton’s heavy particulate load from the Cajon Pass means filters load up faster than in coastal cities. We typically recommend MERV 8 – 11 for standard residential systems; higher ratings can restrict airflow on older Colton blowers not designed for the pressure drop. We assess your system during the cleaning and recommend accordingly.
Dryer vent cleaning is priced separately unless bundled in your written estimate. In Colton’s older homes, the dryer run is often long, routed through walls, or packed with lint beyond the accessible sections. We clean the full run and verify airflow at termination. Call (361) 326-5060 to bundle both services.
