We have been using Don and his family for about 3 years now. After getting screwed by several other AC guys I had all but given up on finding an honest air conditioning repairman. Our air had gone out and I ask a lot of our friends who they used. I heard from multiple people that I had to try TSC. 3 years later and I have zero complaints. They just put in two new units in February, and the price was very reasonable, and I am really happy with the work. They were also in and out in a day and a half. We will need to replace the unit in one of our rentals later this year and will be using Don and the family for that job too. Thanks guys!
