I have a Rheem air conditioner unit. My parts are under warranty for another two years. I was told that I can only get my free parts if I have a company come out and fix the problem for a amount that I feel is unreasonable. Are there a school that may come out and fix a problem like this? How hard is it for an individual to fix this type of problem? I do know I need a fan motor and a capacitor.

I don't know about schools going around and doing jobs like that but motor and capacitor (depending where you live) should be less than $200 if you do it yourself. It is not a difficult job to do however make sure you disconnect the power to unit prior to doing any work and discharge the capacitor as it stores electricity

The cap. Will hold an elec charge several min after diconnecting. Handle carefully or best yet take insulated screwdriver and after disconnect all wires short the terminals against the frame of unit. I have never been bit but...
