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 Marcos, CA
Air duct cleaning in San Marcos runs between $350 and $750 for a typical 3-4 bedroom home, depending on system size, access, and how long it’s been since the last cleaning. San Marcos isn’t like the coastal cities ten miles west. We’re in an inland valley that catches Santa Ana winds, which means fine desert dust and chaparral particulate get pulled into HVAC intakes in ways homeowners in Carlsbad rarely see. If the ducts in your 1990s or 2000s tract home haven’t been opened in ten years or more, give us a call at (323) 918-4345 and we’ll tell you what we’d expect to find before we ever send a crew.
Why San Marcos Homes Are Different
San Marcos grew fast between 1985 and 2010, and the housing stock shows it. Most homes in San Elijo Hills, Rancho Coronado, and Twin Oaks Valley Ranch were built in that window, which means the original flex ductwork is now 20 to 30 years old. That’s the age where connections loosen, flex liners tear, and the accumulated dust stops being a minor nuisance and starts being a real airflow problem. In an older duct system, a good cleaning also works as an inspection, because we can see and photograph exactly where the trouble spots are.
The valley geography matters too. Summer highs sit in the low to mid 90s, so central AC runs hard for four to five months. That’s a lot of air moving through a lot of ductwork. Then between October and March, Santa Ana events push hot, dry 30 to 60 mph offshore winds across the valley, spiking dust infiltration far beyond what coastal homes experience. Add in the wildland-urban interface around San Elijo Hills and Twin Oaks Valley, and ducts here can carry wildfire ash and smoke residue on top of the seasonal dust. We saw it after the 2017 Lilac Fire, and we still see traces of it in return-air plenums today.
Our Main San Marcos Services
Most San Marcos homeowners call us about one of two things: the ducts that carry heated and cooled air through the whole house, or the dryer vent that carries lint and moisture out of the laundry room. Both matter for different reasons, and both are covered below.
Air Duct Cleaning in San Marcos
Air duct cleaning in San Marcos is most impactful in those 1990s and 2000s tract homes where the original flex ductwork has never been opened. We connect professional-grade equipment from Rotobrush and Nikro to your system, agitate and extract the accumulated dust and debris, and leave the plenums and registers looking like they should. In San Elijo Hills and along the Twin Oaks corridor, we routinely pull a fine ochre-tan desert dust mixed with charred chaparral debris from return-air plenums, even in homes with newer windows. That’s the Santa Ana signature, and it makes for a dramatic before-and-after photo. Full details are on the Air Duct Cleaning in San Marcos page.
Dryer Vent Cleaning in San Marcos
Dryer vent cleaning in San Marcos is a different job with a different risk profile. Lint builds up inside the vent run, and because many San Marcos floor plans route dryer vents through attics or along exterior walls with multiple bends, that lint can accumulate faster than homeowners expect. We clean the full run from dryer to exterior cap, not just the first few feet. For the full scope, what to expect, and how to know if your vent is already restricted, see Dryer Vent Cleaning in San Marcos.

Whatever the job, you’ll get a written price before any work starts, and that’s the price you’ll pay. No surprises after the van is in the driveway.

What San Marcos Customers Say
"New house, old dusty ducts. They were gentle in the house, laid down drop cloths, and double checked every register was sealed back up. Air smells fresh now."
- Scott Hemmings"Friendly, calm crew that clearly cared about the house. Covered their shoes, protected the floors, and double checked they'd closed up every vent cover properly. Would have them back."
- Omar Zaid"Ducts and dryer vent both. They put runners down the whole hall and wore booties. Spotless after, and they showed me photos of what came out. Worth every penny."
