Ordered a motor and the main shaft would not turn, had to use pliers. I am an electrician. They would not replace because they said I was not an a/c technician. Also there is a 20% restocking fee and a 50% charge at their discretion if they they want. Check their return policy before you buy and be cautious. Amazon handles a lot of their products too but you have to go through NAHVAC to return something, not amazon.
