I had a guy call me and said that his outdoor fan motor was bad. I had him text me a picture of the data plate from the unit so I could have the correct part when I got there. When I got there. He had already taken the top off and was trying to hammer the motor shaft through the fan blade. "I thought I would save you some time". Well, you didn't remove the set screw and you have now ruined the motor bearings. BTW, your fan motor WAS probably good. Your motors capacitor has swollen to the point that it's separated the top. A hundred dollar service call, including the new capacitor, cost him around five hundred. Fan blade was warped out of shape from him trying to drive the motor out. He was not happy when I told him that the warranty would not cover his stupidity.One of my advisors came in my office with a pissed off customer. Seems he had purchased a used alternator for his truck and paid us to install., but it was crap. He returned it to the junkyard and got a replacement. When the advisor told him he would have to pay the same labor, he blew up and insisted we replace it for free. I told him we would not charge for the second one and gave him the number to the tow company we used so he could tow his truck to someone who would do it for free. Attitude changed and he said he was willing to pay half. I asked if he wanted to use my phone.
Moral of the story: The cheapest is seldom the least expensive. At the time, our labor rate (posted) was $105 per hour; $135 if you supplied parts.
