I had Airtech come out to due a tune up on my gas water heater. Joe the tech, was great. He explained what he would be doing and when the water heater was drained he showed me the condition of my water heater through the camera he had inserted into the unit. It showed that it was in very rough shape. He told me his company could come back and install a new unit and what the cost would be to me. We discussed different water heaters and what would work best for me. Joe was very helpful in answering all of my questions. I have scheduled the installation of a new water heater and anticipate the installers to be just as friendly and courteous as Joe. I will recommend this company to anyone I know with heating, air conditioning and water heater concerns. Great company!
