Altadena homes and their heaters
Half of Altadena's homes were built before about 1945. Houses that old often have wall or floor furnaces, older gravity systems, or ductwork that was added later.
The center of Altadena sits at about 1,355 feet. A furnace that sat unused all summer is most likely to act up on the first cold night.
About 9 in 10 Altadena homes (87.5%) are single-family houses (U.S. Census, 2019–2023), so the usual setup is a furnace in a closet, the attic or under the floor.
About 4 in 10 Altadena homes (38.4%) were built before 1940, and almost 8 in 10 (78.2%) before 1960. These Census figures (2019–2023) are from before the January 2025 Eaton Fire.
We cover all of Altadena, ZIP codes 91001, 91104. ZIP 91104 covers parts of both Altadena and Pasadena.
Altadena isn't its own city. It's unincorporated Los Angeles County, so HVAC permits come from LA County Public Works, Building and Safety.
What we check first
We check the safety side first, then the usual suspects: the igniter, the flame sensor, a pressure switch and the blower. More on our furnace repair page.
Older homes with wall and floor furnaces get the same care. See wall and floor furnace repair.
$69 diagnostic, credited toward the work if you go ahead, and a one-year labor warranty on what we fix.
