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
- Keep two feet clear around the outdoor unit, including snow.
- Light frost on the outdoor unit in winter is normal. A solid block of ice is not.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.

Heat Pump Repair Questions from San Jose Homeowners
What does heat pump repair cost in San Jose?
Most bills land between $230 and $1,120, including the service call. A typical visit is about $720. Night and weekend calls cost more.
Is it normal for a heat pump to freeze?
A thin layer of frost in winter is normal, and the defrost cycle should clear it. Heavy ice that stays usually means a defrost control or airflow problem.
Why is my heat pump blowing cold air?
For a few minutes during a defrost cycle, that's normal. If it keeps going, the usual causes are a stuck reversing valve, low refrigerant or a thermostat set to the wrong mode.
