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.
Air Duct Cleaning Company in El Cajon, CA
Air duct cleaning in El Cajon typically runs $350 – $650 for a whole-home system, with most jobs completed in a single visit. What drives the need here isn’t seasonal upkeep; it’s the reality of running HVAC nearly year-round through 100°F summers, Santa Ana wind events, and wildfire smoke that finds its way into ductwork even when windows stay shut. We’re Hollis Air Duct Cleaning, part of the Garrison Partners family, and we dispatch crews to El Cajon from our San Diego office. Call (361) 326-5060 for a free estimate.
Why El Cajon Homes Are Different
El Cajon’s housing stock is dominated by mid-century ranch-style homes built from the 1950s through the 1970s. Many still run on original galvanized steel ductwork or early flex duct that has never been cleaned. That metal fatigues, seams separate, and the ducts become reservoirs for dust that the Santa Ana winds keep replenishing.
The semi-arid climate means no hard freeze to shut systems down. HVAC runs continuously, accelerating dust buildup. After a Santa Ana event, our technicians regularly find fine ash coating return ducts in foothill neighborhoods like Fletcher Hills and Rancho San Diego, even when homeowners kept every window closed. The outdoor air intakes pull it straight in. In Crest and Jamacha, the older ranch homes sit closer to wildfire-prone terrain, so that contamination happens faster and heavier than in flatter, newer parts of the county.
We also see more rigid metal ducting here than in coastal markets, which changes our approach. Rotary brush systems like our Rotobrush equipment handle it well, but the job takes longer and requires different attachment strategy than flex-duct work.
Our Main El Cajon Services
El Cajon homeowners call us most often for these three jobs, each handled with written pricing and our 365-Day Done Right Promise.
Air Duct Cleaning in El Cajon
We clean the full supply and return network with a Rotobrush rotary brush system and, where needed, Nikro negative-air machines to pull dislodged debris out of the home entirely. In El Cajon’s older ranch homes, we often find galvanized trunk lines with decades of compacted dust and pollen that has never been disturbed. We price by the system, not by the vent, and we photograph the before-and-after condition inside your ducts so you see what changed. Air Duct Cleaning in El Cajon covers full pricing and what to expect on the day.

Dryer Vent Cleaning in El Cajon
Dryer vent buildup is a fire hazard, and El Cajon’s continuous dryer use through hot summers makes it worse. We run professional-grade augers and high-velocity air tools through the full vent run, not just the accessible section behind the machine. For homes with roof-term vents or long horizontal runs through crawl spaces, we bring extension equipment and verify airflow at the exterior cap before we leave. Dryer Vent Cleaning in El Cajon has full details.

Duct Sealing in El Cajon
Original ductwork in 1960s and 1970s El Cajon homes leaks conditioned air into attics and crawl spaces at rates that can waste 20 – 30% of HVAC output. We seal accessible seams with mastic and mechanical fasteners, then pressure-test to verify the seal held. This is often the right follow-up to cleaning, especially in homes where our camera inspection shows separated seams but the ducts themselves are structurally sound. Duct Sealing in El Cajon explains when sealing makes sense versus replacement.
