AC help needed
I got my previous low voltage problem taken care of. Holding in the 118 to 120 range now. New problem is my 14 year old Coleman Mach 15k ac. I've had both sets of coils cleaned. New gasket install...

You need to use an amp clamp/meter and verify the current draw and voltage and go from there. The breaker needs to be HACR rated... heating/AC/refrigerating. I also use thermocouples to check for proper refrigerant flow/temps. It's really easy to check subcooling and superheat that way and see if the filter/strainer or cap tube is restricted. Your symptoms would make me look for a restriction or dragging fan motor... after cleaning the coils. I wish I had a dollar for every drier I've replaced on old systems and made them work like new again! I've added a SUP hard start to a RV AC that had a high amp compressor but that only made it last another 1 - 1 1/2 months. That old AC might not be worth spending very much on it. Craig
