George went above and beyond explaining everything to me so I would understand. He is extremely thorough and did an amazing job cleaning the outside unit. I could not believe how much time he spent cleaning the coils and adjusting valves, etc. He also added some Freon and went up into the attic and checked air handler. Ohls is very lucky to have such an articulate employee. Highly recommend this company. The weight for an appointment was minimal considering the busy season and everyone was so professional at the office.
