Dustin brought his newborn home from the hospital and the AC quit that Saturday. He called Adam, who was there inside two hours, replaced the control board, then checked the rest of the system and texted him photos of every reading. That is the kind of service his reviews keep describing.
Adam fixed it instead. Read the reviews and the same story keeps surfacing: a real diagnosis, a number you hear before the work starts, and no pressure to buy a system you do not need yet.
Adam is very knowledgeable and fixed my AC issue and charged very reasonable price. I showed same with other major AC repair company before Adam. They asked me to replace entire my unit even my AC unit is just 8 years old. Always take opinion from Adam before you decide to replace major components.

Not just the part that failed. While the control board was going in, Dustin got a courtesy check on everything else and a plain explanation of what could wait.
Judith wrote that ATC gave her a good estimate during the job, so the bill held no surprise. Nothing gets replaced just because replacing it was easier.
