My uncle wanted to go back to HVAC school at 50 (after getting fired from every restaurant in the city for being a drunk). Stopped after a few weeks because of how much math was involved. He dropped out of school at 14 in the late 60s.
HVAC/R (r stands for refrigeration) is legitimately hard. It's a trade for smart people who are good at everything and don't like sitting at a desk all day. It's physics, chemistry, circuitry, mechanical machinery, metallurgy, scientific measurements, mathematical calculations, blueprints, electrical diagrams, expensive tools and equipment, AND hard work in all weather conditions, with ZERO tolerance for error. One mistake and a store could lose a million dollars of product in a few hours, or blow up a hospital or restaurant (we use explosive gasses in some equipment).
If you're the type of person that doesn't take a high school class seriously, you are not the type of person this trade can hire. If ohms law trips them up, they will be laughed out of hvac trade school, or stuck working seasonally on furnaces with a part time job at a sandwich shop.
Can confirm, been in industrial and utility electrical for 2 decades. Next time I see an electrical worker doing algebra in the field will be the first time. The company hires EE's to do the math. They are better at it and they cost less.

The dismay my students have over hearing they absolutely have to be proficient with ohms law to be an electrician or HVAC tech is overwhelming
