Yep it's simple as that you can get in electronics stem thermometer get yourself a couple of them from Amazon. 50 degrees outside you should have at least 20 degree temperature rise through the heat pump. I'm assuming that both units are going to be having a return air that is pretty much the same. Milder temperatures they should be able to have a better idea of how the charge is. If the line set is licking the only way they can determine that if they would have to shut down your heat pump and pressure test. Might have to let it sit for a week or two see if it loses pressure. These work well for checking temperatures

buy a pocket thermometer and stick in the vent closest to the air handler in the attic. Then buy a temp/humidity sensor that sits on a table. You should see a 16-20 degree differential between the two temps.

There are several on Amazon.com under $20. See here for one that would work for your purposes.
I would just stick the probe inside the grates? Something like below device would work?
