My AC tripped the breaker on Sunday the day before the 4th of July. I called BEST and Jason came out within the hour. It was not immediately apparent what the issue was, but Jason was great to work with and he charged me the weekend rate, but that is understandable for taking time on the holiday and weekend. He actually did a typical cleaning service on the unit, so the charge was less painful. It turned out that the compressor was shot in just less than a week. Jason came back out and confirmed the death of my unit. He offered a new one at a REALLY reasonable price and installed it the next day. I will recommend these guys to everyone that asks me if I know an honest heating and cooling service company.
