Many homes still have attic ductwork and older HVAC equipment. The AC calls we see most: - **Attic ducts** pulled loose or crushed over the years, so some rooms get little or no air. - **Rental homes near the university**, where systems see heavy use and filters need changing more often. - **Larger homes on bigger lots** with two systems, one of them usually older and failing first. Northridge is in the City of Los Angeles (LADWP power, LADBS permits). Duct problems are covered on [air duct replacement](https://elviraoceanair.com/air-duct-replacement-ca/).
