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 Sunnyvale, TX
Air duct cleaning in Sunnyvale, TX typically costs $450 – $850 for a whole-home system, with most jobs completed in a single visit. We’re Hollis Air Duct Cleaning, and we serve Sunnyvale homes with equipment and methods built for this city’s specific challenges: mid-century ranch and Eichler houses with slab-embedded ductwork, original galvanized steel runs, and the silica dust that seeps through cracked concrete after decades of seismic settling. Call us at (361) 326-5060 for a written estimate before any work begins.
Why Sunnyvale Homes Are Different
Sunnyvale’s housing stock is dominated by mid-century Eichler and other ranch-style homes built between 1950 and 1975. Many still have their original rigid metal ductwork with lapped joints and no insulation. After decades of seismic settling and dry rot, these systems leak heavily and are often contaminated with construction debris from nearby remodel booms.
Because so many Sunnyvale homes are on slab foundations with ducts buried in the concrete, cleaning requires specialized rotary equipment to remove the fine silica dust that infiltrates through cracks. This is a problem rarely seen in neighboring cities with raised foundations. On hot September afternoons, the smell of overheated dust from Eichler slab ducts is a common complaint in the Heritage District. Our technicians know to check the return-air plenum for cracked concrete that lets in radon-laced soil gas, a problem that got national attention after the 2018 EPA radon zone map update.
Sunnyvale’s mild, dry summers and cool, wet winters mean HVAC systems run year-round. The low humidity and occasional winter rains create a unique cycle: dust mites and mold spores bloom during damp months, then get baked into ductwork during the first hot spells. This requires more frequent coil and duct cleaning than in more consistently dry or humid regions.
