Yeah but was he right? I tried it on my last wall and it made a huge difference.

I used 3/4 inch foam board on a north-facing wall (the cold one) and it dropped the temp by almost 4 degrees in the room. Big difference like you said, but make sure you tape the seams right or you'll get condensation behind it and that's a whole other problem.
