If the unit has aux heat, it may very well need 40 amps. Read the
manual.

If you have to ask, you don't have the skills. I wouldn't
reccomend to open a panel box unless you've seen it done several
times, and have someone experienced working with you.

: I'd call the hvac installer, but, clearly, they didn't think it
