my AC unit outside is making a squealing sound and the fan is not spinning when on. selling my house soon I need advice
Fix it so you don't screw the new owner.
Turn it off and call a local company to fix it before you do real damage to it... running without the fan can cost you a big bundle.
You may even have to replace the outdoor unit before a closing due to an inspection that will be done on your home.. replace it before and use it as a marketing tool to sell your home...
