My split unit heat pump run fine for a day or two then it stops cooling and goes into retard,I will turn it off and turn it back on and it runs fine for a few more days and goes out again..any idea what the problem is..I'm thinking reversing valve...
Ran across an elderly couple with this goodman heat pump,they said they haven't used it in almost 2yrs,because it was costing them $800 per month to run it.any ideas to what's wrong..
