My AC and heating is making weird noises whenever we turn it on. The higher we turn the pressure the louder the noise gets. Do I just need a new AC?

 

Are you talking about the blower motor?

If so, just get a new one. They're dirt cheeeeeep and it only takes like 3 minutes to swap, if you're slow like me. You can probably do it in half the time I can.

Get the kind that has the wheel with it, or get a new wheel too. They're often impossible to get off without destroying anyway.
