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.
Air Duct Cleaning Company in Riverside, CA
Air duct cleaning in Riverside, CA typically costs $350 – $650 for a whole-home system and is scheduled by appointment with a written price locked in before work begins. Riverside’s inland climate and Santa Ana wind patterns create dust conditions that differ sharply from coastal Southern California, which changes both how often ducts need cleaning and what equipment is required to do the job properly. At Hollis Air Duct Cleaning, our crews are dispatched from the Inland Empire office and work Riverside neighborhoods daily. Call us at (361) 326-5060 for a free estimate.
Why Riverside Homes Are Different
Riverside sits in a dust corridor. The Santa Ana River wash and surrounding dry scrubland generate fine particulate that gets pulled into HVAC systems year-round, but especially during Santa Ana wind events that can drop a visible layer of silt into ducts in a single afternoon. Unlike coastal Orange County, Riverside has no marine layer to settle dust, so airborne particles stay suspended and circulate until they deposit inside ductwork.
The housing stock here compounds the challenge. Early-1900s Craftsman bungalows in the Wood Streets and Northside neighborhoods often have retrofitted ductwork squeezed through attics or crawlspaces, with tight turns that trap debris. The 1980s-2000s tract homes in Orangecrest and Mission Grove use flexible duct runs that collect dust at joints and sag points. Mid-century homes in the Eastside and University neighborhoods frequently run original metal ducts with decades of buildup and leak points. Summer temperatures over 100°F from May through October mean systems run constantly, recirculating whatever is inside the ducts.
After a Santa Ana wind event, technicians in Riverside regularly find ducts coated with fine silt from the wash and nearby hills. Homes near the Santa Ana River bottom or in Alessandro Heights see this most acutely. Standard residential vacuuming does not remove this gritty layer; rotary brush systems and negative-air equipment are required to dislodge and extract it.
Our Main Riverside Services
Most Riverside homeowners who call Hollis need one of these three services. Each has its own page with detailed pricing, process, and neighborhood-specific notes.
Air Duct Cleaning in Riverside
We clean supply and return ducts, registers, and the main trunk lines using a Rotobrush rotary brush system paired with Nikro negative-air collection. In Riverside, the combination of fine silt and long summer runtimes means we often find a compacted layer of dust that requires more contact time per vent than in moister climates. We photograph the interior of your ducts before and after so you see what came out. Air Duct Cleaning in Riverside.

Dryer Vent Cleaning in Riverside
Dryer vent cleaning removes lint buildup from the transition duct, wall run, and exterior termination. Riverside’s dry heat and Santa Ana winds accelerate lint accumulation at exterior vents, and many older homes in the Wood Streets area have long, convoluted vent runs through unconditioned attic space that are prone to partial blockages. A cleared vent dries clothes faster and reduces fire risk. Dryer Vent Cleaning in Riverside.

Duct Sealing in Riverside
Duct sealing closes leaks in the duct system using mastic sealant and metal-backed tape at joints and connections. In Riverside, leaking ducts in attics pull in 140°F summer air, forcing your AC to work harder than necessary. Many Orangecrest and Mission Grove homes with flexible duct runs have gaps at joints that were never properly sealed during original construction. We test with a pressure gauge and show you the before-and-after leakage numbers. Duct Sealing in Riverside.
