My A/C went out during one of the hottest weeks in summer and the house was miserable. Stone Services was able to send Mike out the very next morning and he quickly and correctly found the culprit and had it up and working again in no time. I was more impressed when he gave me an accurate explanation of the problem and explained that a part would be needed but not until the later in the year. He took the extra time to make sure the system was otherwise up to snuff and ready for the heat! Very affordable for such good service and I didn't feel like he was trying to "sell" me anything I didn't need.
