You can rent FLIR cameras and DIY it. That's what we did. Helped us with a before / after on attic insulation and with helping us determine what windows needed replacing. You just need to find the hotspots (where you are losing heat). Not sure what else a full survey gives you.

@LongAndWinding did the work. It's not hard.
