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 Rialto
Air duct cleaning in Rialto typically costs between $350 and $650 for a full residential system, and the job usually takes three to five hours. Most Rialto homeowners book because they’re seeing dust settle on furniture right after cleaning, noticing weaker airflow from vents, or smelling something stale that won’t go away. We know Rialto’s housing stock, and we know exactly what builds up inside its duct runs. Omar Haddad leads our local Cardinal Air Duct Cleaning team, and you can reach us at (737) 727-2314 for a free estimate that actually reflects the work your house needs.
Why Cardinal Air Duct Cleaning Is Rialto’s Preferred Air Duct Cleaning Company
Rialto homeowners tend to ask the same three things before they book: what the job costs, how long it takes, and whether we can actually show them the work was done. We answer all three before the van even pulls up. Every job starts with a written price per system, not per vent. You approve that number before we touch a single register, and it does not change at the door. That’s our no-hassle upfront pricing, and it’s the reason most of our Rialto bookings come from referrals, not ads.
Our technicians are background-checked, uniformed, and you’ll know their name before they arrive. We run Rotobrush rotary brush systems for agitating debris, Nikro HEPA-filtered negative-pressure vacuums for extraction, and Abatement Technologies containment equipment where the job calls for it. When Omar Haddad dispatches a crew to Rialto, the truck carries professional-grade gear, not a shop vac. Part of the Relay Home Co. family, founded in 2005, we operate under The Relay Visibility Guarantee: a live trackable arrival window, before-and-after photo proof, and a digital invoice payable by link. Every booking, without exception. And the 365-Day Done Right Promise backs the work for a full year. If it’s not right, we return and correct it at no charge.
Air Duct Cleaning Services in Rialto
Air Duct Cleaning Services in Rialto start with a camera inspection of the full supply and return system, then move to mechanical agitation of every accessible run, and finish with negative-pressure extraction. That last term matters: negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. A standard residential cleaning in Rialto runs $350 to $650 depending on system size, access difficulty, and the amount of buildup. Homes with the original ductwork from the post-WWII boom often fall on the higher end of that range.
Full System Cleaning
This covers the entire duct path: supply runs, return runs, the air handler cabinet, the blower motor cage, and the plenum boxes. If a cleaning skips the air handler, it leaves the single largest collection point for dust and lint untouched. We open every register, clean every accessible run, and photograph what we find before and after.

Video Inspection
Before we start, we send a camera down the supply and return runs to find blockages, collapsed sections, rodent debris, or buildup the registers can’t reveal from the surface. After the cleaning, we run the camera again. You see the exact same duct sections in the before-and-after photos, not stock images.

HVAC Duct Cleaning in Rialto
HVAC Duct Cleaning in Rialto means treating the entire air handling system as one connected unit, not just the metal tubes that move air around. That includes the evaporator coil, the blower motor, the drain pan, and the return air plenum. A system that moves less air than it should usually has buildup on the blower motor cage or a clogged evaporator coil. Rialto homes run their AC hard through June, July, August, and September, and that constant runtime means the blower sees far more air volume than a coastal house of the same size. More air volume means more particulate passing through, and more particulate means more buildup where it counts.
Air Handler and Blower Motor Cleaning
The blower motor cage is where fine grit settles and then bakes solid in Rialto’s dry heat. Left alone, it reduces airflow at the register and makes the motor work harder than it should. We clean it as part of every full-system job, and photograph it before and after without being asked.
Return Duct Cleaning
Return ducts pull unfiltered or partially filtered air from the house back to the system. In Rialto, return runs are often un-insulated, open-tray style or flex duct that has sagged and split over the decades. Dust from the prevailing winds off the Cajon Pass and the adjacent foothills enters through the return grates and accumulates fast. We clean the entire return path, not just the last few feet visible from the register.
Trusted Brands We Service in Rialto
We service all major residential and light commercial equipment found in Rialto homes: Honeywell electronic air cleaners, Aprilaire media filters, Guardsman filtration components, and standard single-speed and variable-speed air handler brands installed throughout San Bernardino County. Because we’re local to the Inland Empire metro, our crews carry common replacement filters, gaskets, and access hardware for the brands most common in Rialto. That means less waiting for parts when a filter frame or register box needs replacement mid-job. If your system is a current production model from the last two decades, we service it. If it’s older, we’ll tell you honestly what cleaning can and can’t fix.
Common Air Duct Cleaning Problems We See in Rialto Homes
- Attic insulation fiber in the duct interior. Much of Rialto’s ranch-style housing built in the 1950s and 1960s has duct runs through un-insulated or poorly sealed attics. The attic insulation settles, breaks down, and gets pulled into the return system through loose joints and gaps around register boots.
- Windblown grit from the Cajon Pass corridor. The prevailing wind pattern pushes dry airborne dust and fine grit across Rialto from the northwest foothills. Homes without tight return duct sealing draw that particulate directly into the system, where it settles in the blower cage and along duct floors.
- Baked-on particulate on the evaporator coil. Rialto’s summer temperatures push AC runtime to extreme levels, and fine dust that reaches the coil gets baked into a hard layer that reduces heat transfer. The symptom is lukewarm air at the register even with a functioning compressor.
- Dryer lint and rodent debris in crossover runs. In older Rialto floorplan-basic homes, return ducts sometimes share chases with dryer vents or abandoned plumbing runs. Lint, small debris, and occasionally rodent droppings and nesting material find their way into the return system through wall cavities and unsealed joints.
Pricing for Air Duct Cleaning in Rialto, CA
A standard residential air duct cleaning in Rialto runs $350 to $650 for a full system, one flat price per system agreed before work starts. Smaller homes or single-story ranches with easily accessible duct runs may land around $300. Larger two-story homes, systems with hard-to-reach attic sections, or heavy buildup from years of deferred maintenance can approach $700 in rare cases. Commercial duct cleaning in Rialto runs $0.15 to $0.35 per square foot depending on building size, duct layout, and whether after-hours work is required. What affects cost here specifically: attic access difficulty (many Rialto ranches have low-clearance roof cavities), the number of return grates (some older homes only have one or two, some have been retrofitted with more), and whether the blower motor cage has baked-on buildup that needs extra agitation time. The price you approve is the price you pay. Call (737) 727-2314 for a free estimate from Omar Haddad and the local Cardinal Air Duct Cleaning team.

FAQs About Air Duct Cleaning in Rialto
Most Rialto homes need a full system cleaning every 3 to 5 years. Homes with pets, smokers, recent renovations, or a tendency to leave windows open during windy months fall closer to every 2 to 3 years. The best way to know is a camera inspection. We’ll show you what’s actually in the ducts before recommending any work. Call (737) 727-2314 to schedule an inspection at no charge.
We charge per system. One flat price for the full supply and return system, agreed in writing before we start, no per-vent tally. Per-vent pricing is how the bait-and-switch operators in Rialto and across the Inland Empire work: a low teaser number that balloons once vents are counted and add-ons appear. We don’t do it. Call (737) 727-2314 and we’ll give you a real system price over the phone.
A camera inspection of all accessible supply and return runs, mechanical agitation with rotary and whip tools to break debris loose, and negative-pressure extraction with HEPA filtration so the debris leaves through the vacuum, not into your living room. The blower motor cage and air handler get cleaned as part of every full-system job. Before-and-after photos are taken of the exact same duct sections and delivered to your phone. Call (737) 727-2314 to talk specifics about your Rialto home’s system.
No, and we won’t pretend to. Proper duct cleaning is a scheduled job that takes three to five hours and uses professional-grade equipment, not a 20-minute spray-and-dash. We schedule Rialto jobs within a few business days in nearly every case, and you get a live trackable arrival window rather than a vague “sometime between 8 and 5.” Call (737) 727-2314 and we’ll find the next open slot that works for you.
Yes and no. The lint in your dryer trap is mostly cotton and synthetic fabric fibers from clothing. What builds up in Rialto’s HVAC ducts is broader: windblown grit from the Cajon Pass corridor, attic insulation fragments, skin cells, pet hair, dust mites, and fine sand from the region’s dry soil. The EPA’s baseline finding that indoor air can be two to five times more polluted than outdoor air is common in Rialto precisely because this Grit-heavy material has no place to go. A dryer vent cleaning is a separate service from air duct cleaning, though many Rialto homeowners book both together. Call (737) 727-2314 and we’ll walk you through what your house specifically needs.
