although it's old, if a minor issue can be resolved to get a little more goodie out of it, it's worth finding out why it's overloading, like the duke said. i'm late responding, but maybe somebody else can benefit. freon level, capacitors, burnt wires, burnt contactors, dirty coils can all cause overheating. a failing start relay can also cause a problem resulting in overload. never hesitate to get a 2nd and 3rd opinion. some just want to sell and make money. some of us want to do honest service work and gain a permanent customer. when it's time to replace, be connected to someone you already trust.
