Los Angeles Housing Stock
Census figures put the median build year in Los Angeles at 1964, so a typical house here has about 62 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Los Angeles has roughly 515,000 owner-occupied homes, or 36.3% of households. Homes here have a median value of $879,500 and households a median income of $80,366. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Los Angeles County show 3 hail days and 10 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Los Angeles County also had 5 tornado days in that period.

California Permits, Efficiency Rules and Rebates
California is in the DOE's Southwest region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). The Southwest also sets a minimum EER2, which measures efficiency at peak heat. Expect the contractor to pull a mechanical permit for a replacement job in Los Angeles. If a bidder suggests skipping it, move on. Also ask for a California license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- A combi boiler frees up space and replaces your water heater.
- Ask your gas or oil company about rebates on condensing boilers.
- For a steam system, hire a contractor who works on steam regularly.
