How much does HVAC school cost in California?

California has 48 HVAC schools and 60 listed programs in this directory. 47 of those programs publish a tuition, which is the only n that enters the dollar figures — the other 13 are counted as schools and programs but not as prices. Among published prices the median is $18,000, the 25th percentile is $3,700, and the 75th percentile is $21,500. That spread is 86.2% above the national median of $9,665 (n=254).

The California mix includes 14 certificates, 26 diplomas, and 7 aas degrees. Certificates have a median of $3,400 (range $736–$26,377, n=14). Diplomas have a median of $21,500 (range $15,500–$26,377, n=26). Associate degrees have a median of $2,760 (range $2,760–$6,200, n=7). Listed lengths run 5 months to 2 years, with a median of 10 months (n=60). California requires a state HVAC license for independent work, so a program whose hours map to that license is worth more than a cheaper catalog that does not.

HVAC technicians in California earn a BLS OEWS median of $57,180 (10th percentile $38,170, 90th $81,370; about 38,420 employed).
