I wish I could put ZERO stars. I made an appointment with them for their advertised A/C check up. The appointment was on Friday between 10:00 am and Noon. I received a call from the office at 11:15 saying they need to re-schedule. They had other appointments that were more important than mine. They have already been paid by me and they tell me they can come out in the following friday. I told them to cancel any future appointment's, I don't want them near my house. Bad business. I realized I had forgotten about the payment I made to them and called them back for my refund. After 10 minutes on hold, the call was sent to voice mail.
