So 1 of my roof ac's feel a little weak after running awhile. How hard is it to recharge the roof top? Can you buy a kit to do it myself? How do you know when it is full? Thanks for help.
I have replaced a few roof AC units. Find a good deal on a new scatch -n- dent and install it. I installed one I bought from Adventurerv.net on my wife's grooming van and it works perfectly and has for a couple of years now.
