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 Riverdale
Air duct cleaning in Riverdale, GA typically runs $350 – $650 for a full residential system and is usually completed in one visit. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we’ve been working in homes along the GA-85 corridor and throughout Riverdale long enough to know what these houses hide in their walls.
Our crews dispatch from the Atlanta office and serve Riverdale directly. That means we understand the local housing stock: the brick ranches from 1968, the split-levels from 1974, the townhome clusters built during the 2000s boom near Valley Hill Road. We know the clay dust that filters through return vents in April, the pollen loads that coat blower motors in March, and the crushed flex ductwork our techs find in attics off Church Street and Roberts Drive. When you call (361) 326-5060, a live person answers, and we schedule you inside a window we actually keep.
Riverdale’s position just south of Atlanta puts it in the path of everything: heavy spring pollen, summer humidity that stays above 70% for weeks, and that fine Georgia red clay dust that seems to find every gap in a house. Homes here run their HVAC systems year-round, and the ductwork pays the price. Our Air Duct Cleaning team treats Riverdale as a core service area, not an afterthought.

Our technicians are background-checked and uniformed. You know who’s walking into your home before they arrive. We use professional-grade equipment: Rotobrush rotary brush systems for mechanical agitation, Nikro negative-air machines for source removal, and HEPA filtration from Abatement Technologies to keep what we pull out of your ducts from settling back into your living room.

We’ve been doing this since 2004, and we’ve learned that the only way to run a trade business is to put the standard in writing and then meet it.
Riverdale homeowners aren’t looking for the cheapest coupon in the mail. They’re looking for the bid they can trust, from a crew that won’t turn a $299 special into an $800 invoice once the van is in the driveway. Our prices are flat per system, agreed before work starts, and they don’t move at the door.
Ductwork Cleaning in Riverdale
Ductwork Cleaning in Riverdale means more than pushing a brush through visible vents. In this market, it means dealing with systems that have been accumulating debris since the Johnson administration, often in ductwork that was never designed for the central air that got bolted on later.
A typical residential Ductwork Cleaning in Riverdale runs $350 – $550 for a standard system, with larger homes or systems requiring more extensive restoration work reaching $650. Commercial systems start around $800 and scale with square footage and system complexity. We price by the system, not by the vent, so you know the full cost before we start.
Source Removal and Negative Pressure
We use the negative-air method: a Nikro portable HEPA vacuum attaches to your trunk line, creating suction that pulls dislodged debris toward the collection unit while we agitate the duct walls with rotary brushes. This isn’t shop-vac work. The negative pressure keeps contaminants from escaping into your home during the cleaning, which matters in Riverdale’s older homes where ducts may not be fully sealed.
Supply and Return Duct Cleaning
Many crews clean what they can reach and skip the rest. We separate supply and return runs, cleaning each independently because they carry different debris loads. Returns pull in clay dust, pollen, and pet dander; supplies push conditioned air and can harbor mold in humid conditions. In Riverdale’s 1960s ranches, returns are often undersized and work harder, accumulating more debris per square inch.
Air Duct Inspection in Riverdale
Air Duct Inspection in Riverdale is where we find the problems that cleaning alone won’t fix. Given the age of much of this city’s housing stock, we consider inspection non-negotiable before quoting restoration work. A standard video inspection runs $150 – $250, and we apply that fee toward any cleaning or Duct Sealing in Riverdale work you proceed with.
We feed a camera through your trunk lines and branch ducts, recording what we find: crushed flex runs, disconnected joints, rodent damage, mold growth, or the undersized returns that plague floor-furnace retrofits. You see the footage. We explain what it means for airflow, energy bills, and indoor air quality. Then we quote the fix in writing.
Video Documentation and Written Report
Every inspection includes recorded video and a written report with still images of problem areas. In Riverdale’s older neighborhoods, we typically find original ductwork with R-4 insulation that’s degraded to dust, or flex ducts crushed by decades of attic traffic. The report becomes your baseline for deciding what needs immediate attention and what can be scheduled.
System Performance Testing
We measure static pressure across your system and temperature differential at supply and return registers. Numbers don’t lie. In homes with floor-furnace-era retrofits, we often see static pressure 40% above design limits, which strains the blower motor and drives up electricity bills. The inspection identifies whether cleaning will help or whether duct redesign is the real solution.
Trusted Brands We Service in Riverdale
Our equipment roster includes Nikro negative-air machines and HEPA vacuums, Honeywell and Aprilaire filtration products, and Abatement Technologies containment systems. We don’t use hardware-store gear. These are the same tools specified for commercial and healthcare applications, and we maintain them to manufacturer standards. For Riverdale homeowners, that means we can source replacement filtration media and components without waiting on national supply chains. If your system needs a Honeywell media filter upgrade or an Aprilaire whole-house dehumidifier integration after cleaning, we stock the parts and install them during the same visit.
Common Air Duct Cleaning Problems We See in Riverdale Homes
- Floor-furnace retrofits with undersized returns. In the GA-85 corridor neighborhoods, many duct systems were sized for floor furnaces and later adapted to central air, leaving returns too small to balance airflow. Cleaning the ducts doesn’t fix the pressure imbalance; the return needs to be rebuilt or supplemented.
- Crushed attic flex ducts. The original flex runs in 1960s and 1970s Riverdale ranches weren’t designed for the foot traffic they’ve received. We regularly find sections flattened to half their diameter, choking airflow to back bedrooms and causing the system to run longer.
- Rodent intrusion in unsealed trunks. Older duct sealing has dried and cracked. Mice enter through gaps near the air handler, nesting in insulation and leaving debris that recirculates. We find this most often in homes near wooded lots off Roberts Drive and Valley Hill Road.
- Mold in supply plenums from humidity. Riverdale’s summer humidity stays high for months. When cold supply air meets an uninsulated metal plenum in a hot attic, condensation forms. Over seasons, this becomes mold growth that cleaning alone won’t prevent without addressing insulation and airflow.

FAQs About Air Duct Cleaning in Riverdale
Because the problem usually isn’t dirty ducts; it’s undersized returns from a floor-furnace retrofit. Cleaning removes debris, but it doesn’t enlarge a 10-inch return trying to serve a 3-ton system. We measure static pressure during inspection. If your return is choking the blower, we quote the rebuild separately, in writing, before touching anything. Call (361) 326-5060 and we’ll diagnose it properly.
We find them with camera inspection, then replace damaged sections with new insulated flex duct secured to code, not just taped. On a 1968 brick ranch off GA-85, our tech found a crushed flex run in the attic and a return so undersized that the blower motor was pulling hard; after source removal with negative pressure and HEPA filtration, we resealed the main trunk and rebuilt the return to restore balanced supply and return ducts. The work is part of our standard restoration scope, priced before we start.
A full video walkthrough of trunk lines and branch ducts, recorded footage with still images, static pressure testing, and temperature differential readings at registers. You get a written report with our findings and flat-price recommendations. The inspection fee applies to any work you proceed with. In Riverdale’s older homes, we almost always find something the homeowner didn’t know about.
Every 3 – 5 years for maintenance cleaning, but original 1960s – 70s systems should be inspected first. Decades of accumulation, degraded insulation, and possible rodent damage mean these systems often need restoration, not just maintenance. If you’ve never had your ducts inspected since owning the home, start there. Call (361) 326-5060 to schedule.
Yes. Newer townhomes typically have properly sized ductwork in conditioned space or sealed attics, with fewer access issues. We can often complete these cleanings faster, with less restoration work. Older ranches require more inspection time, careful handling of brittle original materials, and frequently need sealing or return modifications. We adjust our approach to what the house actually needs, not a one-size-fits-all protocol.
