"I wanted to let you know about this technician that was out to our office a few days ago. There have been many issues with the HVAC in this office since I have been here. We have seen many technicians come and go, but Larry was amazing! He came in and fixed all of the issues and everything is finally running smoothly. He was also extremely pleasant and helpful. I didn’t know who else to direct these comments to, but I feel that he deserves the recognition! I wanted to make sure that I let someone know about his excellence in service and attitude!"
