Very poor service! First they forgot about my appointment. I called to find out and they was able to bring on someone after hours. But was still disappointed because I had to leave work early for nothing. The only thing Jeff (technician) fixed was replacing the circuit board protector fuse (charge $180) and only had the fan running. Jeff claimed that it was a bad thermostat and I had to call back NVEnergy to fix it. By this time I've had no AC for two weeks in this heat wave. NVEnergy came in showed me on his voltage device that there's no voltage to start the thermostat and said I needed to call back Gibson Air. I spoke to Jeff from Gibson Air and had the NVEnergy tech explained the situation. Jeff was going to charge me AGAIN for something they didn't fix from the beginning. I told Jeff it wasn't fair for me to pay again for something that wasn't fully fixed during the first visit. Very disappointed considering the reason I called in the first place is their "good" reviews. Now makes me question are their reviews real????????
