“Austin Schmidt arrived at the expected time, introduce himself and presented an overview of the planned maintenance service to be preformed. He started with the upstairs unit, documented the status/ condition before and after service. Noted the difference between the two units and proceeded with the second unit. Again documenting the before and after service. Summarize with me the services performed asked if I had any questions or concerns. Completed his work in a timely professional manner leaving me a feeling of confidence in my systems operational status.”
