When sizing a backup generator, do you need to include both heating and AC? Usually they don't run at the same time but some compressors run with Aux heat strips are on.
Would you calculate it (HVAC) just as you would for a service?
This is not a whole house backup but pretty close. It is a two-story house and they want all lower level lights, some designated receptacles throughout the lower level, the garage circuit, including garage door openers, the cook top and the lower level HVAC.
Here's a couple pictures of the HVAC nameplate.
ACs MCA=31.5 Max Brkr=50A
Heat MCA=52.5 Max Brkr=60A
