San Jose Housing Stock
The median San Jose home dates to 1975, according to the Census ACS. That makes the typical house about 51 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. Owners live in 55.9% of occupied homes, roughly 183,000 households. Homes here have a median value of $1,187,800 and households a median income of $141,565. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Santa Clara County show 6 hail days and 4 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.
