Air Duct Services in San Diego & Orange County

Where we got our start

In 2018, Nadi Offer and Daniel Lezmy rented one van, loaded it with duct-cleaning equipment and started taking calls around San Diego. Nearly 15 vehicles later, ductwork is still the job we know best. It's also how most of our customers first meet us.

Your ducts carry every bit of air your heating and cooling system moves. When they're dirty, leaking or crushed somewhere in the attic, you feel it in the rooms: dust that comes back two days after you clean, a bedroom that never cools down, a smell when the system kicks on. The fix depends on which of those problems you actually have, and that's what this page is here to sort out.

Which duct service do you need?

Start with what you're noticing. A tech will confirm it on site, but this gets you close.

• Dust, pet hair, remodel debris or a stale smell. That's buildup inside the ducts. Air duct cleaning removes it from the supply runs, returns and registers.
• A musty, smoky or sour odor that cleaning alone didn't fix. Duct sanitizing is a treatment applied after cleaning to go after odor and microbial growth on duct surfaces.
• Weak airflow in some rooms, hot and cold spots, rising bills. Usually a physical problem: a disconnected run, a crushed flex duct, torn insulation. That calls for air duct repair, and often duct sealing on the joints.
• Ducts that are brittle, poorly routed or failing throughout. Past a certain point, patching stops making sense and air duct replacement is the honest answer.

If you can't tell, that's normal. Plenty of homes have a little of everything. A ductwork inspection gives you a clear picture before you spend money on the wrong thing.

Why ducts in this region take a beating

Southern California is easy on people and hard on ductwork. Most homes here run ducts and the air handler through the attic, where summer heat bakes flex duct and dries out tape. Inland valleys like El Cajon, Santee, Escondido and Mission Viejo get that heat hardest. Near the coast, salt air works on metal parts and the marine layer adds moisture that dust sticks to. Santa Ana winds and wildfire smoke push fine particles into every gap in the house.

Age matters too. The 1950s–70s homes in Clairemont, North Park and Point Loma, and the 1970s–90s tract homes across Irvine and south Orange County, are often still running original or decades-old ducts.
