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 Ojus
Air duct cleaning in Ojus typically runs $350 – $650 for a full residential system, and most jobs are scheduled within a few business days. Our dispatch office in Miami coordinates crews who serve Ojus directly, so we’re familiar with the specific duct problems this area throws at homes.
We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we’ve been doing this since 2004. In Ojus, we’re not dealing with ordinary dust buildup. This humid, low-lying pocket of northeast Miami-Dade sees water get into ductwork through slab cracks and saturated soil after heavy rains. That changes everything about how we approach a job. Our Air Duct Cleaning team arrives with moisture meters, camera inspection gear, and the understanding that your call might be about a musty smell that started after last week’s storm, not just dirty vents. Call us at (361) 326-5060. A real person answers, 24 hours a day.
Why Hollis Air Duct Cleaning Is Ojus’s Preferred Air Duct Cleaning Company
Ojus homeowners know the difference between a crew that understands local conditions and one that’s running the same playbook they use everywhere. We’re the former. Our technicians are background-checked, uniformed, and trained to The Garrison Code, which means arriving inside the quoted window, pricing in writing before touching anything, and leaving the site clean.
We don’t do estimates that balloon once we’re inside. The price is written down before work starts, and it doesn’t move at the door. Every job carries our 365-Day Done Right Promise in writing. If the work fails within a year, we come back and make it right at no charge, including a free second visit. That’s not a slogan. It’s on the paperwork.
Our phones are answered by a live person around the clock. No voicemail loops. No callback queues. When you’re dealing with water in your ducts after a storm, you don’t want to wait until Monday for someone to call you back.
We serve Ojus with the same equipment commercial crews use: Rotobrush rotary brush systems, Nikro negative-air machines, and filtration products from Honeywell, Aprilaire, Abatement Technologies, and Guardsman. Professional-grade tools, not hardware-store gear.
HVAC Duct Cleaning in Ojus
HVAC Duct Cleaning in Ojus means something different than it does in drier climates. Here, the job often starts with identifying whether the problem is dust, moisture, or microbial growth, and whether the ductwork can be cleaned or genuinely needs replacement. A typical residential HVAC duct cleaning in Ojus runs $350 – $550 for a standard single-family home or duplex, with larger systems or homes requiring antimicrobial treatment running toward the higher end.
We use a negative-air method, which means we hook a powerful vacuum to your trunk line and maintain suction throughout the cleaning so dislodged debris doesn’t escape into your living space. Then we agitate the interior surfaces with a Rotobrush rotary system to break up buildup. In Ojus, we almost always follow with an antimicrobial treatment because the humidity here means mold spores will resettle if we don’t.
When Ducts Can Be Cleaned
Surface mold, loose debris, and moderate dust accumulation respond well to proper cleaning. If moisture readings come back normal and the insulation is dry, we’ll clean, treat, and seal. We document everything with before-and-after photos and moisture readings for your records.
When Ducts Must Be Replaced
Standing water inside a duct run, saturated insulation, or galvanized steel that’s rusted through means cleaning won’t last. The moisture source remains. In those cases, we write up exactly what needs replacement and why, with photo documentation your insurer can use.
Vent Cleaning in Ojus
Vent Cleaning in Ojus addresses the supply and return registers where air enters and exits your rooms, but it also includes the short duct runs behind each vent that collect the most visible debris. A standalone vent cleaning for a typical Ojus home runs $150 – $250, though most homeowners bundle it with full system cleaning for better value.
The vent covers themselves often show the first signs of Ojus’s moisture problems. Black spotting on the grille, rust stains on the surrounding drywall, or a persistent musty smell right at the register usually points to a duct run behind the wall that’s holding moisture. We pull every cover, inspect the boot and first few feet of duct, and check with a moisture probe.
Supply Vent Focus
Supply vents push conditioned air into your rooms. When they’re partially blocked by debris or coated with microbial growth, your system works harder and your air quality drops. We clean the full run from trunk to grille, not just wipe the visible part.
Return Vent Inspection
Return vents pull air back to the handler. They’re your system’s breathing point, and in Ojus they often pull in humid air through gaps in the building envelope. We check the seal around the return box and note any air leakage that could be driving moisture into the system.
Trusted Brands We Service in Ojus
We stock parts and filtration products from Honeywell, Aprilaire, and Guardsman, so Ojus customers don’t wait on special orders when a component needs replacement mid-job. Our equipment roster includes Rotobrush rotary brush systems for mechanical agitation and Nikro negative-air machines for containment. These are the same tools we use on commercial sites. For filtration upgrades after cleaning, we carry Aprilaire media filters and Honeywell electronic air cleaners. If your Ojus home needs a filtration solution that handles the local humidity load, we’ll size it to your system and explain exactly what MERV rating makes sense for your setup. No guesswork. No hardware-store compromises.
Common Air Duct Cleaning Problems We See in Ojus Homes
- Moisture intrusion through slab cracks. Ojus sits on some of the lowest ground in northeast Miami-Dade. After heavy rain, water wicks up through cracks in slab-on-grade foundations and enters under-slab or attic duct runs. We see this regularly near Highland Lakes Boulevard and in the older ranch-style duplexes built in the 1960s.
- Microbial growth in galvanized steel trunk lines. The original ductwork in Ojus’s 1950s – 1970s housing stock is often galvanized steel with deteriorated internal insulation. Once moisture hits, black growth colonizes the rough interior surface within days.
- Saturated flex duct in crawl spaces. Homes with slab-on-grade construction sometimes have flex duct routed through tight crawl spaces or attics where roof leaks or condensation soak the outer jacket. The insulation becomes a sponge that never fully dries.
- Leaky joints pulling in humid outside air. Original duct seams in older Ojus homes were sealed with tape that has long since failed. Every gap pulls in unconditioned, humid Miami-Dade air, raising the dew point inside the duct and promoting condensation.

FAQs About Air Duct Cleaning in Ojus
It depends on what we find inside. If there’s standing water or saturated insulation, cleaning alone won’t solve it and the microbial growth will return within weeks. We run a camera inspection and take moisture readings first. If the duct material is intact and dry after source control, we can clean and treat. If the insulation is waterlogged or the metal is rusted through, we document the damage for replacement and help you present that to your insurer. Call (361) 326-5060 for an inspection – estimates are free.
Yes. We photograph the interior condition before any work, record moisture content percentages with calibrated meters, and note the specific locations and extent of damage. Our field report includes timestamped photos, moisture readings, and a written assessment of whether each section is cleanable or requires replacement. This documentation has been accepted by insurers handling post-storm claims in Ojus. We do this standard on every water-intrusion call.
Most Ojus homes need duct inspection every two to three years, and full cleaning more often than inland Miami-Dade because of the humidity load. The combination of older housing stock, slab-on-grade construction, and the area’s low elevation means moisture issues develop faster here. If you smell mustiness when the A/C cycles, that’s your signal to call, regardless of the calendar.
Yes. Given Ojus’s tropical monsoon climate and year-round humidity, we apply an EPA-registered antimicrobial treatment after every cleaning that involves visible microbial growth or moisture history. Skipping this step leaves spores in the system that will recolonize. The treatment is included in our antimicrobial service tier, not sold as an add-on.
It will if the smell is coming from debris or surface growth inside the ductwork. But if the source is ongoing moisture intrusion through a slab crack or a roof leak that’s wetting the insulation, cleaning alone won’t last. We identify the source before quoting any work. If the ducts are cleanable and we treat them, the smell should dissipate within 48 hours of service. If the problem is structural, we’ll tell you that upfront so you don’t spend money on a temporary fix. Call (361) 326-5060 and we’ll sort out which situation you’re in.
