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.

AfterAir Duct Cleaning Company in San Bernardino, CA
Air duct cleaning in San Bernardino runs most homeowners $380 – $620 for a full system on a typical 2,000 – 2,600 sq ft home, with dryer vent cleaning adding $120 – $190. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family (founded 2005), and we’re the duct specialist that gives you a written price before a single vent is touched. If your home sits near the foothills off Highway 330 or in the flatlands around Hospitality Lane, San Bernardino’s dust, summer heat, and older housing stock mean your ducts work harder than most. Call us at (737) 727-2314 and a live person answers, day or night.
Why San Bernardino Homes Are Different
San Bernardino sits in a valley that traps fine particulate from three directions: the Cajon Pass funnels desert dust in from the high desert, the Santa Ana winds push dry grit through the mountain gaps, and the 215/10 interchange corridors keep a steady low haze of brake dust and tire wear moving across the city. Homes here pull that air inside, and the return ducts slowly pack with a gray, sandy sediment that builds faster than most homeowners expect. It’s not dramatic. It’s just constant.
The housing stock adds another layer. Much of San Bernardino’s inventory dates from the 1950s through the early 1980s, and many of those systems have original or long-ignored return ducts running through unconditioned attics. Summer attic temperatures regularly pass 130°F here, and that thermal stress pulls at old flex duct connectors, loosens joints, and bakes settled debris into a crust that a basic vacuum pass won’t remove. We run Rotobrush rotary brush systems with Nikro HEPA extraction on these older setups because they need mechanical agitation, not just airflow.
Some of the older neighborhoods, particularly around the historic downtown grid and the blocks east of E Street, also have tight closet HVAC closets and short return runs that were never sized for modern filtration. We see a lot of Aprilaire media filters installed on undersized return plenums, which loads them faster and shortens filter life. None of this is a knock on the homes. It’s just the reality of working in San Bernardino’s older stock, and it’s why a proper cleaning here includes checking airflow at the return and supply registers, not just brushing the trunk line.
Our Main San Bernardino Services
San Bernardino homeowners call us for three jobs most often: clearing clogged dryer vents that run through long, hot attic routes; deep-cleaning the main supply and return ductwork that carries dust throughout the house; and cleaning the HVAC equipment itself so the whole system breathes. Each service has its own San Bernardino page linked below so you can go straight to the one you need.
Dryer Vent Cleaning in San Bernardino
Long dryer vent runs are common in San Bernardino, especially in single-story ranch homes where the laundry room sits in the center of the house and the vent has to travel 15 to 30 feet to an exterior wall. Every bend in that run is a place lint packs down, and an attic route means the dryer works against San Bernardino’s summer heat all year. Clogged vents here cause slow dry times, overheated dryers, and a real fire risk from lint accumulation. We use professional rotary brushes to break the lint free and Nikro HEPA vacuums to pull it out. Get the full picture on our Dryer Vent Cleaning in San Bernardino page.
Air Duct Cleaning in San Bernardino
The supply and return ducts in San Bernardino homes collect a fine mix of desert dust, pollen from the foothills, and the kind of settled grime that recirculates every time the blower kicks on. We don’t do the bait-and-switch per-vent game. We price the whole system as one job, clean the supply side, the return side, the trunk lines, and the branch runs with a Rotobrush system paired to a Nikro HEPA negative-air vacuum, which means loosened debris gets pulled straight into the filter, not back into your living room. See the full breakdown on Air Duct Cleaning in San Bernardino.
HVAC Cleaning in San Bernardino
The blower wheel, evaporator coil, and housing are the engine of your system, and in San Bernardino they work through long cooling seasons. A dirty blower wheel moves less air, which means weaker airflow at the registers and a system that runs longer to hit the thermostat. We pull the blower, clean the wheel and motor housing, clear the coil, and check the drain pan and line. It’s the same before-and-after photo standard we apply to every job. Details are on the HVAC Cleaning in San Bernardino page.

FAQs About Air Duct Cleaning Company in San Bernardino
Most San Bernardino jobs are scheduled same-day or next-day, depending on your neighborhood and what you need. You get a live trackable arrival window through The Relay Standard booking experience, so you’re not sitting around waiting for a four-hour window. Call (737) 727-2314 and a live person will set it up.
Duct and vent cleaning is interior work on your own HVAC system, so HOA approval isn’t required for the cleaning itself. The only exception would be if your dryer vent exits through a shared wall or attic space in a condo or townhome complex, where access may need to be coordinated. We’ll tell you if that applies to your property.
No. We run negative-pressure extraction on every San Bernardino job, which means the vacuum is pulling air out of the ducts the whole time the brush is working. Loosened debris goes straight into the HEPA filter, not into your living room. You’ll see the before-and-after photos from your own system when the job is done.
