In California, we can use either Manual J or ASHRAE methods for loads.
EnergyPro uses the ASHRAE methods, so that is OK to use. I would ask
how EQuest does loads, and if it's ASHRAE, I'd use that if you are
familiar with it. We are also allowed to use Manual D or ASHRAE methods
for ducts and the ASHRAE methods are in the ASHRAE handbook. For simple
residential, it's a simple duct losses spreadsheet that you can make up
yourself.
