The guy didn't know why the AC was broken

I responded to a repair call from a customer in the valley.

Customer called because the AC was not working.

I asked for more information from the customer, but he was unable to describe any additional problems. I asked a customer if there was any air coming out of the system and he said no. I asked a customer if the thermostat was working and he said yes. These two questions can eliminate a lot of problems in my mind. I left the workshop and headed out to the valley. I called the customer to let the man know that I was on the way. The address for the customer was about 25 minutes away from the workshop. The first thing I did after arriving on the scene of the repair was ask a customer a couple of additional questions. That’s when I found out that the customer had the AC set to 65° when the machine shut down. If the customer had told me this when I was on the phone, then I would have been able to give him better directions. I honestly did not believe that the customer even needed a repair service, but I took care of the problem. The evaporator coils on the AC machine were completely Frozen. When you set the temperature on the thermostat too low, the air conditioner has to work extremely hard. This can cause the coils to freeze up when it is extremely hot outside. I told the customer that he needed to wait a couple of hours before the AC would work again. I performed a full system tune-up on the machine and assured the customer that everything was working properly. He had to wait for the coils to thaw out.
