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.

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
- Ask what the emergency fee is before the truck is sent.
- If the CO alarm goes off, get everyone outside and call 911 or the gas company before you call an HVAC company.
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
