San Diego Housing Stock
The median San Diego home dates to 1978, according to the Census ACS. That makes the typical house about 48 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. San Diego has roughly 249,000 owner-occupied homes, or 47.6% of households. Homes here have a median value of $848,500 and households a median income of $104,321. Those two numbers drive the labor adjustment in our estimate.
Between 2020 and 2025, NOAA's Storm Events Database logged 6 hail days and 18 days with damaging thunderstorm winds in San Diego County. 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.

California Licensing and Efficiency Rules
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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in California the company should carry a state license or registration. Ask for both.
Before You Hire
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Maintenance plans often put members first in line for emergency calls.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
