Anaheim Housing Stock
The median Anaheim home dates to 1973, according to the Census ACS. That makes the typical house about 53 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Anaheim has roughly 49,000 owner-occupied homes, or 45.9% of households. Homes here have a median value of $771,700 and households a median income of $90,583. Those two numbers drive the labor adjustment in our estimate.
Orange County had 2 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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.

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. Equipment replacements in Anaheim generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their California license or registration number and a certificate of insurance with the quote. 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
- Ask your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- For a steam system, hire a contractor who works on steam regularly.
