I’m sorry if this is in the wrong place I’m still new and finding my way around.

I have a 2007 Honda Civic lx coupe, I’ve had it a few weeks now and I’ve had to replace quite a bit trying to make it a dependable daily drive, I’m really considering cutting my losses and selling it to find something else but I really like the car.. anyway, I’ve replaced the Mode Control motor, the blower motor/fan, the climate control unit, all the relays and fuses and that seems to have fixed some of my issues however, now I have notice my a/c line freezing up. The a/c blows cold and I only drive the car to and from work for about 20 minutes rash way. I recently started smelling Freon in the cabin and I’ve determined that it’s my a/c pressure switch. My question is, to replace the switch do I have to vacuum the Freon and have it refilled? Or can I just quickly remove and replace it and then fill it with a can of Freon from the auto parts store?

The system needs to be properly emptied, and then filled with a proper set of gauges. Before you get the shop to do that, if you're smelling freon inside the cabin it could be the evaporator leaking. Need to put dye in the system and see where the leak is coming from.
