Bookkeeper with AC struggle

My bookkeeper is struggling with an AC issue. As a minority female I think she may be being taken advantage of. This 1998 build York AC (H1RA048S06B) was serviced a month ago and checked out fine, correct Freon levels, etc. Two weeks later the system was blowing warm air and she noticed the outdoor condenser fan was not running. She called the tech who did the service and he guessed over the phone that the condenser fan motor was bad. He suggested she pull the breaker and take a stick and see if the fan was seized. It was not. I suggested she re-set the breaker and try to spin the fan with power on. She did so and the fan ran for a few minutes and then it stopped again. I told her she needed the tech on site. Because she had a home warranty on the equipment, another tech came and tested the charge and stated she would need 10 lbs of Freon and maybe a capacitor and service. He further stated that the lack of Freon was why the fan motor would not run. He quoted a pile of money, based mostly on the Freon expense. She became suspicious given the Freon level was fine a month ago. Now she does not know what to do. Techs are flat out here and finding an honest/competent one seems to be near impossible. Shouldn’t the tech have started by simply testing the resistance of the capacitor and replacing if out of spec?
