Census figures put the median build year in Los Angeles at 1964, so a typical house here has about 62 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Los Angeles has roughly 515,000 owner-occupied homes, or 36.3% of households. Homes here have a median value of $879,500 and households a median income of $80,366. Those two numbers drive the labor adjustment in our estimate.
NOAA storm reports for Los Angeles County show 3 hail days and 10 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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. Los Angeles County also had 5 tornado days in that period.

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.
- Many heat pumps carry a 10-year parts warranty if they were registered. Find out whether yours was.
- Book maintenance twice a year, once before summer and once before winter.

Heat Pump Repair Questions from Los Angeles Homeowners
What does heat pump repair cost in Los Angeles?
Most bills land between $210 and $1,030, including the service call. A typical visit is about $660. Night and weekend calls cost more.
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.
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.
