What tools do I actually need to change a capacitor or a contactor?

A nut driver set, insulated screwdrivers, needle-nose pliers and a meter. That is most of the residential electrical work. Add a crimper and wire strippers if you are doing anything with terminals.

What size nut driver fits HVAC panel screws?

5/16 inch covers the large majority of panel and blower screws, with 1/4 inch second. If you buy one driver, buy 5/16.

Insulated tools - necessary or marketing?

Necessary if you are working near live terminals, which on HVAC you often are. Insulated handles are a second line of defence, not a substitute for killing power at the disconnect and confirming zero volts.

What is a fin comb for?

Straightening bent condenser fins so air can get through the coil again. Hail, weed trimmers and pressure washers all bend them, and a flattened coil quietly costs capacity all summer.
