A/C Service Ports - 1994 Ford (Coachmen Catalina)

Are these valves on the A/C service ports? I can get no pressures from the ports - assuming that these are valves and they are closed. The dash air is working to some extent, but I believe it is low on refrigerant. The compressor kicks on, but it only cools to about 60 degrees. I have tried opening these with a wrench, but they won't budge, and I am afraid to put much force on them (I have a recent history of breaking stuff that is not made to twist).

I posted this on the Ford Chasis site as well. Would like to add a little 134A, but am stymied.
