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, TX
Air duct cleaning in San Marcos runs between $349 and $1,250 for most homes, depending on square footage, system type, and how long it’s been since the ducts were touched. We’re Kestrel Air Duct Cleaning, and we work in a city where inland valley heat, Santa Ana dust, and a fire event from 2014 still leave residue inside ductwork that homeowners don’t see until someone opens a register and looks. If your San Marcos home was built between the mid-1980s and the 2000s, you likely have original flexible ducts that sag, separate at the joints, and collect debris faster than newer rigid systems. Call (469) 972-3151 for a written quote before any work begins.
Why San Marcos Homes Are Different
San Marcos sits in an inland North County valley, and that position changes how HVAC systems behave. Summer temperatures routinely push into the high 90s and low 100s, so air conditioners here run continuously for months, cycling air through ductwork at a rate coastal cities like Carlsbad or Encinitas never see. More cycles mean more particulate pulled through the returns and deposited along duct walls. Then the Santa Ana winds arrive in the fall, funneling dry, dusty air directly into exterior returns and intakes in neighborhoods north of Barham Drive and around Twin Oaks Valley Road.
But the single event that separates San Marcos from neighboring Vista or Escondido is the May 2014 Cocos Fire. It burned nearly 2,000 acres straight through residential areas near Cal State San Marcos and Twin Oaks Valley, pushing smoke and fine ash into hundreds of homes. Duct systems that predate the fire were rarely remediated afterward. We still find ash residue in homes that were never professionally cleaned in the months following the fire. That baseline contaminant is specific to San Marcos work, and it’s one reason we treat every cleaning here as a removal job, not a quick once-over. Add in a housing stock built out largely between the mid-1980s and 2000s, with builder-grade flexible ducts now 20 to 40 years old, and you have a city where duct cleaning is often the first time anyone has looked inside the system since the house was framed.
Our Main San Marcos Services
San Marcos homeowners call us about two things most often: the air ducts that move conditioned air through the house, and the dryer vent that carries lint and moisture outside. Each has its own page for San Marcos below, with local pricing and specifics for this city.
Air Duct Cleaning in San Marcos
When we clean air ducts in San Marcos, we’re addressing years of debris that built up during sustained summer cooling cycles and seasonal Santa Ana events. Older flexible ducts in 1980s and 1990s homes often show joint separation, which lets attic air and insulation particles mix with conditioned air. Our process uses negative-air extraction, meaning a powerful vacuum pulls loosened debris out of the system while containment keeps it out of your living space. Rotobrush equipment agitates the duct walls so settled dust and any Cocos Fire ash residue actually releases, rather than staying packed in place. See the full breakdown on our Air Duct Cleaning in San Marcos page.
Dryer Vent Cleaning in San Marcos
Dryer vents in San Marcos clog faster than homeowners expect because the same valley dust that coats patio furniture gets pulled through the laundry room and into the vent line. Long vertical runs in two-story homes near Cal State San Marcos add resistance, and a partially blocked vent forces the dryer to run longer cycles, which overheats the appliance and wastes energy. We clean the full run from the dryer to the exterior termination point, including the lint trap bypass area most box-store tools can’t reach. A clogged dryer vent is also a fire hazard, and this job is best left to a trained technician with the right extraction equipment. Details, including pricing, are on our Dryer Vent Cleaning in San Marcos page.

What pushes a San Marcos job toward the higher end of these ranges is usually duct age and configuration. Homes built in the 1980s and 1990s often have original flexible ducts that require more time to clean properly, and two-story layouts near Cal State San Marcos with long vertical vent runs add labor. Whatever the number, you get it in writing before we touch a single vent, and that price holds. No door-step revisions, no surprise line items.

What San Marcos Customers Say
"My wife's allergies were awful every morning. Had the ducts done and it's made a real difference. Tech was on time and wore booties in the house without me asking."
- Rob Pendergast"Bought an older home and the previous owners had pets everywhere. After Kestrel did the ducts the stale smell was just gone. On time, quick, and they showed me the filter they pulled."
- Preston Ngata"Our dryer was taking two cycles to dry a load. They cleaned the vent and pulled out a frightening amount of lint. Dries in one cycle now and honestly I feel better about the fire risk."
