^^^ Good advice!
Another reminder is to visually inspect the cooling coil at least once per year. Was working with a friend last year who was complaining that his AC wasn't cooling correctly. We popped on top of his 5th wheel and discovered a LARGE wasp nest had been built on top of and between his coils. That stuff was like concrete! Took a lot of scrubbing to get his coils cleared but it did fix his cooling problem.
