There is quite a price difference, but what is the functional difference
between HVAC breakers and standard ones?

I didn't know there was any difference. I use standard breakers in my
panel for my A/C unit; always have.

A standard 240-volt, single phase breaker is a breaker. If the breaker is
the right size for the HVAC equipment then it will work.

I have never seen a HVAC breaker, maybe a three phase breaker?

"HACR" breaker.

Scroll about half way down.

The mfr listing for the equipment will determine the
OC protection which *must* be used.

Sounds like BS. Never heard tell of such a thing. Use standard breakers
for the a/c and furnace, then go out to dinner and not worry about it.
