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 Air Duct Cleaning Across Muscoy
Air duct cleaning in Muscoy typically runs $350 – $650 for a full residential system, with post-storm or flood-damaged ductwork requiring camera inspection and moisture documentation before we can tell you whether cleaning or replacement is the right call. We dispatch from our Inland Empire office and serve Muscoy directly, so you’re not waiting on a crew driving out from Los Angeles or Orange County. Call (361) 326-5060 and a live person will pick up, day or night, to schedule your free estimate.
We’ve been working in the pocket of unincorporated San Bernardino County that is Muscoy long enough to know the local housing stock: modest ranch homes built from the 1940s through the 1970s, many with original flex duct routed through unconditioned attics and under-floor crawlspaces, plus the occasional unpermitted addition or mobile home where duct routing turns into a puzzle. That matters because you can’t price what you can’t see, and you can’t clean what you can’t access. Our Air Duct Cleaning team runs video inspection before quoting any job in Muscoy, especially after the Santa Ana wind events that funnel desert grit straight through the Cajon Pass and into your return grilles.
Why Hollis Air Duct Cleaning Is Muscoy’s Preferred Air Duct Cleaning Company
We’re part of the Garrison Partners family, and we’ve been doing this since 2004. In Muscoy, that longevity means something. Homeowners here have watched fly-by-night outfits roll through with coupon prices that balloon once the van is in the driveway. We don’t work that way. The price is written down before any tool comes out of the truck, and it doesn’t move at the door.
Our technicians are background-checked and uniformed, and they arrive inside the quoted window. That’s The Garrison Standard, and it applies to every job we run in Muscoy, from a routine cleaning off Highland Avenue to a post-flood assessment near the lower end of Cajon Blvd. The 365-Day Done Right Promise backs every repair in writing: if the work fails within a year, we return and make it right at no charge, including a free second visit.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail loops. No callback queues. When Muscoy’s Santa Ana winds kick up and you’re staring at reddish-brown dust on your return grilles, you don’t want to leave a message and hope someone calls back Monday.
Vent Cleaning in Muscoy
Vent Cleaning in Muscoy means pulling every supply and return register, agitating the duct walls with a rotary brush system, and extracting debris under negative pressure so nothing escapes into your living space. In this town, the job is rarely routine. The same wind funnel that makes Muscoy’s summers bearable, the Cajon Pass, also deposits silica-heavy desert grit that standard vacuum attachments won’t touch. We see it caked inside vent boots and coating the first few feet of flex duct behind every return grille.
When to Schedule Vent Cleaning
If you’re wiping reddish-brown film off your return grilles every few days after a Santa Ana event, your vents are telling you the duct system behind them is loaded. Same if you smell dust every time the AC cycles on, or if a room never cools evenly despite good airflow at the register. We use Rotobrush rotary systems and Nikro negative-air machines to dislodge that grit and pull it out of the house entirely, not just push it deeper.
What Vent Cleaning Costs in Muscoy
A standard vent cleaning for a Muscoy single-family home runs $180 – $340 for register and boot cleaning as part of a larger system service, or $350 – $650 for a full supply and return duct cleaning with video inspection. Homes with unpermitted additions or irregular routing may need additional access points, which we discuss and price in writing before starting.
Air Duct Repair in Muscoy
Air Duct Repair in Muscoy is often a replace-or-clean decision, especially after water intrusion. The older flex duct in this area’s 1940s – 1970s housing stock soaks up crawlspace moisture like a sponge, and once the insulation layer is wet, no amount of cleaning restores it. We document everything on video with moisture readings so your adjuster can see what we see.
Post-Storm Duct Assessment
After a wind-driven rain event or crawlspace flooding, we run camera inspection down every affected run before quoting. Dry trunk lines get cleaned under NADCA standards with negative pressure and HEPA filtration. Water-logged flex gets replaced. We don’t pressure-wash or fog soaked duct and call it good. That insulation never dries in Muscoy’s low-lying crawlspaces, and it becomes a mold reservoir that the next AC season blows straight into your bedrooms.
Insurer-Ready Documentation
We provide video footage, moisture readings, and written findings formatted for insurance submission. Phone snapshots don’t cut it with adjusters anymore. Our documentation shows pre-existing condition, water staining, microbial growth where present, and the exact runs that require replacement versus those that qualify for cleaning. That specificity gets claims approved faster and protects you from paying out of pocket for work your policy should cover.
Trusted Brands We Service in Muscoy
Our equipment roster includes Rotobrush rotary brush systems for agitation, Nikro negative-air machines for source removal, and filtration products from Honeywell, Aprilaire, and Guardsman. We don’t show up with hardware-store vacuums and call it professional. For Muscoy homeowners dealing with post-wildfire ash or Santa Ana grit, that distinction matters. The same tools we use on commercial jobs in San Bernardino County run on your residential system, and we stock common fittings and flex duct sizes so repairs don’t wait on parts orders. When we find a collapsed or water-damaged run during inspection, we can often replace it same visit because we carry the inventory.
Common Air Duct Cleaning Problems We See in Muscoy Homes
- Silica-heavy dust accumulation from Cajon Pass wind events. The fine reddish-brown grit that coats Muscoy return grilles within days of a Santa Ana wind is abrasive and re-aerosolizes every time the AC kicks on. Standard filters don’t catch it, and it accelerates wear on blower motors and coils.
- Collapsed flex duct in unconditioned crawlspaces. Original 1950s – 1970s flex duct sags at low points, collecting moisture and debris. In Muscoy’s older homes, these runs are often buried under decades of dust and inaccessible without cutting access panels, which we locate and price before starting.
- Unpermitted additions with improvised duct routing. We regularly find bedroom additions off the original structure where a previous owner tapped into the trunk with flex duct that’s undersized, uninsulated, or routed through an exterior wall cavity. That “ductwork” can’t be cleaned effectively and usually needs proper replacement to meet code and perform.
- Post-storm water intrusion with no visible signs. Homeowners smell musty air but see dry registers. We find standing water in the low point of under-floor runs, sometimes weeks after the rain stopped, because Muscoy’s clay-heavy soil drains slowly and crawlspaces stay damp.
Pricing for Air Duct Cleaning in Muscoy, CA
A full residential air duct cleaning in Muscoy runs $350 – $650 for a typical single-system home with 8 – 15 registers. That includes supply and return ductwork, register and boot cleaning, blower motor compartment vacuuming, and video inspection of accessible trunk lines. Commercial systems or homes with multiple HVAC units start around $800 and scale with square footage and access complexity.
Post-storm or flood-damaged jobs require a separate assessment phase: $150 – $250 for camera inspection, moisture mapping, and written documentation. If replacement is needed, we quote that separately after documentation, with flex duct replacement running $45 – $85 per linear foot depending on diameter and insulation R-value. Dryer vent cleaning, which we strongly recommend alongside duct cleaning in Muscoy’s dust-heavy environment, adds $120 – $180.
Every price is written down before work starts. No per-vent pricing. No teaser coupon that jumps at the door. We agree on one flat price per system, and that’s what you pay. Call (361) 326-5060 for a free estimate.

FAQs About Air Duct Cleaning in Muscoy
It depends on what the camera and moisture meter show. Dry trunk lines can be cleaned under NADCA standards with negative pressure and HEPA filtration. Water-logged flex duct with soaked insulation must be replaced; cleaning it traps moisture and creates a mold reservoir. We document everything on video with moisture readings so your adjuster can approve replacement where it’s needed. Call (361) 326-5060 to schedule the assessment.
Muscoy sits directly in the Cajon Pass wind funnel, so Santa Ana events push silica-heavy desert grit and wildfire ash straight into your HVAC system. That grit is finer and more abrasive than typical household dust, and it bypasses standard filters. We see it coating return grilles within 48 – 72 hours of a strong wind event, measurably more than in neighboring San Bernardino just a few miles west. A full system cleaning with rotary brush agitation and negative-air extraction removes it from the duct walls, not just the visible registers. Call (361) 326-5060 for a free estimate.
We provide video inspection footage, dated moisture readings with specific humidity percentages, written findings describing water staining and microbial growth where present, and a line-item scope separating cleanable dry runs from water-damaged runs requiring replacement. This documentation is formatted for insurance submission and includes our technician’s observations under NADCA assessment standards. Adjusters deny claims based on phone snapshots; they approve them based on this level of specificity. Call (361) 326-5060 and we’ll walk you through what your policy likely covers.
Yes, frequently. We find improvised duct taps, undersized flex runs, and routing through exterior wall cavities that wasn’t designed for airflow or access. Those conditions don’t meet current code and often can’t be cleaned effectively because the duct isn’t properly supported or sealed. We locate these issues during video inspection, explain what we found, and quote proper replacement where it’s the only solution that will actually work. The written price covers whatever access we need to cut and whatever proper materials we need to install. Call (361) 326-5060 for an inspection.
In Muscoy’s dust-heavy environment, yes. The same Santa Ana grit that loads your supply and return ducts also packs into dryer lint pathways, restricting airflow and creating fire risk. We pull 2 – 4 pounds of compacted lint and grit from Muscoy dryer vents on a typical job, especially on homes where the vent run is long or has multiple bends. Dryer vent cleaning runs $120 – $180 and we bundle it with full duct cleaning at a flat combined price. Call (361) 326-5060 to add it to your estimate.
