We had an A/C unit go out at 11pm and I called and asked for a tech early the next morning.  Robert showed up promptly at 8am and took care of the repair quickly. The price was reasonable.  Two days later our other unit went out and I called in the afternoon.  They said they were booked up and I let them know we really were hoping to get somebody out that night.  The receptionist called me back after talking to the owner and he said he would personally show up as long as I didn't mind it being a little later.  He showed up right at 9pm and took care of the issue.  Everything has been great!
