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 Running Springs, CA
Running Springs sits at 6,000 feet in the San Bernardino Mountains, where wildfire smoke from below-ridge valleys and heavy pine pollen get pulled into ductwork year-round. At Hollis Air Duct Cleaning, we clean, seal, and restore ventilation systems built for mountain conditions, not suburban flatland. Call (361) 326-5060 for a free estimate.
Why Running Springs Homes Are Different
Most Running Springs houses are mountain cabins, 1950s-1980s chalets, and A-frame retreats tucked along Highway 18 and Highway 330. These homes were built for scenery, not modern HVAC efficiency. Exposed attic runs, under-floor ducts in crawlspaces, and wood stove heating create airflow paths that suburban tract homes simply don’t have.
The 6,000-foot elevation means ducts cycle between dry summer heat and wet winter snowmelt. We’ve found moisture-corroded flex duct in attics above Snow Valley and blackened filters in cabins near Fredalba after wildfire season blew smoke through ridge vents owners assumed were sealed. Pine needles, ash, and rodent debris collect faster here than in valley towns because the forest presses right against the structure. When we open a return vent in a Running Springs cabin, we often find the previous cleaner skipped the crawlspace entirely.
Winter ice dams and spring melt can saturate attic insulation and duct wrapping, which is why our crews carry moisture meters and check for compromised flex runs, not just surface dust.
Our Main Running Springs Services
Running Springs homeowners call us most often for three jobs shaped by mountain conditions.
Air Duct Cleaning in Running Springs
We use a Rotobrush rotary brush system paired with Nikro negative-air machines to pull pine pollen, wildfire ash, and rodent debris from the exposed duct runs common in Running Springs cabins. After major San Bernardino Mountain wildfires, we’ve pulled smoke-damaged flex duct from homes whose owners believed their vents were sealed. Every job gets a written price before we start and before-and-after photos of your own ducts. Air Duct Cleaning in Running Springs
Dryer Vent Cleaning in Running Springs
Mountain homes run dryers harder in winter when outdoor clotheslines are useless. Lint buildup in long vent runs through unheated crawlspaces or exterior walls is a genuine fire hazard in wooden structures heated by wood stoves. We clean the full run from appliance to termination, test airflow with a manometer, and flag corroded or sagging sections before they become a problem. Dryer Vent Cleaning in Running Springs
Duct Sealing in Running Springs
Running Springs ducts leak more than valley systems because temperature swings at 6,000 feet expand and contract metal joints and mastic seals year after year. We seal with mastic and mechanical fasteners, then pressure-test to verify the fix. Sealing is especially critical after wildfire season, when gaps that lost heated air in winter now pull smoke particulate inside. Duct Sealing in Running Springs

FAQs About Air Duct Cleaning Company in Running Springs
No permit is required for routine duct cleaning or dryer vent maintenance in Running Springs. Duct sealing that involves structural modification may need San Bernardino County review; we handle the paperwork if it applies. Call (361) 326-5060 and we’ll check your specific job.
Smoke particulate is small enough to pass through standard filters and settle in ductwork. After major San Bernardino Mountain fires, we routinely find blackened filters and smoke residue in cabins miles from the fire line. Cleaning and sealing together are the only way to remove existing deposits and stop new ones from entering.
We schedule Running Springs jobs with weather buffers and morning windows to avoid afternoon ice formation on Highway 18 and Highway 330. If conditions are unsafe, we call ahead and reschedule at no penalty. Your safety and ours come before any appointment.
