We called Mike at Thermal Techs and he was very helpful, courteous, honest and knowledgable about the problem we were having with our air conditioning. He explained everything to us in terms we would understand and illustrated exactly where the problem was and the best solution for it. He was also very professional and understood that we had a 3 month old baby who wasn't sleeping without Air Conditioning. Now I have a well running A/C and a sleeping baby. Thanks Mike! We would recommend you to anyone!
