I had a couple other questions about the air throughout the house, and he took the time to offer suggestions.”

“Brad was very helpful in explaining the issue. We had a new AC unit installed last week and it was not working as well as we thought it should. Brad came out and was able to identify a few areas that needed to be adjusted, he fixed them and the AC seems to be running as it should now. Brad seems very knowledgeable, he is pleasant and was very good to work with.”
