My A/C was blowing room temperature air... checked it out and the fan wasn't spinning.
After a bit of research I learned it was probably the capacitor... so I bought a new one (cheap part) and replaced it... now the A/C works again!
Saved a $100+ contractor bill... my best DIY repair to date woot!
(and no going without a/c isn't an option since I rent out rooms in the house ^^)
