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 South San Francisco, CA
Air duct cleaning in South San Francisco means working with fog that rolls through the San Bruno Mountain gap nearly every evening and homes built in the 1940s and 50s with original sheet-metal ductwork. Those two facts shape almost every residential job we do here, and they’re also why the work differs from what homeowners need in Daly City, San Bruno, or anywhere further down the Peninsula. Morton’s Air Duct Cleaning handles both air duct cleaning and dryer vent cleaning for South San Francisco homes, always with a written price before any work starts. Call (323) 918-4345 to talk through what your house actually needs.
Why South San Francisco Homes Are Different
South San Francisco sits at a wind gap between San Bruno Mountain and the bay, which means marine air accelerates through the city and delivers persistent humidity that’s noticeably more intense here than in San Mateo or neighboring San Bruno. That fog moisture works its way into forced-air systems through poorly sealed registers and attic duct runs, and it keeps working year-round. For homeowners in Linden, Paradise Valley, and the streets around Orange and Chestnut Avenues, the result is ductwork that stays damp longer and grows microbial buildup more readily than systems in dryer inland cities.
The housing stock compounds the problem. Most of the flat residential districts were built quickly in the 1940s and 1950s for shipyard and industrial workers, and many of those modest single-family homes still have their original galvanized or bare sheet-metal ducts. We regularly open those systems and find decades of accumulated debris, plus rust spots and surface mold where the marine moisture has been sitting. These compact postwar homes also tend to have short, convoluted duct runs tucked under low-pitched roofs or through uninsulated crawl spaces, which makes a thorough cleaning more than a quick vacuum pass. Our crews work with Rotobrush and Nikro equipment sized for exactly these tight, older layouts.
Our Main South San Francisco Services
Most South San Francisco calls come down to two jobs: cleaning the air ducts that move heated and cooled air through the house, and clearing the dryer vent that carries lint out. Both matter more in this city because of the fog and the age of the housing stock.
Air Duct Cleaning in South San Francisco
We clean the full duct system – supply and return registers, trunk lines, branch runs, and the plenum – using truck-mounted Rotobrush and Nikro equipment with HEPA filtration. On South San Francisco’s postwar homes, our techs pay particular attention to the crawl-space runs and short attic connectors where rust and microbial growth concentrate. You’ll get a written price for the whole system before anything starts, shoe covers and drop cloths on every visit, and a photo of the clean-up before the crew leaves.

Dryer Vent Cleaning in South San Francisco
South San Francisco’s older homes often route dryer vents through crawl spaces, under low roofs, or out through short exterior runs that collect lint quickly in the damp air. We clean the entire vent line from the dryer connection to the exterior termination using professional Nikro equipment, removing the compacted lint that slows drying and poses a fire risk. Every job includes a written price before work begins and a photo of the cleaned termination once it’s done. Dryer Vent Cleaning in South San Francisco

- Shelby Dunham"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."
