Air Duct Repair & Sealing in North Hollywood, CA

When we pressure-test ductwork in North Hollywood, the leaks are almost never where the homeowner guessed. They are at the plenum seams, at the register boots, and at the joints nobody could see — including in newer homes near the NoHo Arts District that were never sealed properly at the build. North Hollywood spans the arts district's converted warehouses and mid-century apartment blocks around Lankershim and Magnolia, plus post-war single-family streets running north toward Sherman Way. A large share of that housing predates central air entirely, so systems were retrofitted into attics and crawlspaces that were never laid out with ductwork in mind.

What we run into in North Hollywood is shaped by retrofitted duct runs threaded through attics that were never designed for them, frequently crushed where they cross low framing. So the work starts with a diagnostic rather than a guess — we walk the accessible runs, check static pressure and airflow at the registers, and find where the loss actually is instead of sealing whatever is easy to reach. Repairs get made with mastic and fiberglass mesh, never tape, which fails fast in an attic this hot.

Attic temperatures across North Hollywood are the reason tape repairs do not last. Homes in NoHo Arts District and Valley Village and Whitsett Ridge routinely show us three or four generations of failed tape on the same joint, each applied by somebody who assumed the last attempt was the problem.

Same-day appointments are usually available across North Hollywood, and we hold the price we quoted. If a technician finds something that changes the scope, you hear about it before anything gets done. (951) 555-0170.
