I found Mason via a brand AC website where he is listed as the dealer. I checked the homestar review, he is named perfect, as it is too late and I was so frustrated after a hot long Saturday afternoon without cold air to cook me down, I sent him email at 10:00PM, I did not expect he replied right away, but an hour later, he replied, I was so surprised, and next day we made a plan. He showed up even before the time, during the check-up, he explained very well about what happened to the AC and my thermostat, end up we had to replace it. He finished the work professionally and on time, before he left for home, he checked everything to ensure they all worked perfectly, the most important part for me to see a person a profession or not is to know whether he knows what he is doing, to me Mason is a perfect example to everyone to trust him on the work in his profession, I would recommend him to anybody.
Thanks Mason for the excellent work done
