My model is not cooling-does this unit require freon and if so how do i do it myself?
Hi, it's possible you need freon, if you need freon, then there's a leak in your system, you will have to mend leak first. you will need refrigerant manilold and gauges, truthfully you can't, you will need to know, what type of freon you need, there's different types, and you will also need to know operating pressure, best you should check mechanic.
