An R/V tech will tell you that you need a new A/C so be sure the guy you calls is also willing to replace it or you will have to pay a 2nd service call from someone who will. There's almost nothing to check other than to see if the fins are cleans and the inside filter is clean. If you can get on the roof you can do this yourself. You can't recharge the unit. There is a slim chance it could be the start capacitor but I don't think it would make any difference if it was hot or less hot outside.
I will replace the unit myself. From everything I've found on the internet a new Coleman Mach 3 will replace my current Mach 3. I'll be able to use the same thermostat and it's already a ducted unit. The 4 hold down bolts and then a simple plug-in.
I hope it's as easy as it sounds.
