The 2 guys that came were great. They new what the were doing and fast. AC works great. The only reason I gave them a 4 is commutation on the time of the appointment. The lady on the phone said 10 – 11 a.m. I had to call them at 11:10. They did show up up around 11:30 a.m. I hope I would never have to use them again but if I do I will and I would recommend them.
