Santa Ana Housing Stock
Half the homes in Santa Ana were built before 1968 (Census ACS median), so the typical house is about 58 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. Santa Ana has roughly 36,000 owner-occupied homes, or 44.6% of households. Homes here have a median value of $657,800 and households a median income of $88,354. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Orange County show 2 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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.
