"Punctual and Responsive"
Nathaniel arrived as scheduled, was quick to identify the problem with my air conditioning system, and had the problem corrected in as short a time as possible. He explained the problem and the correction needed to me. When authorized by me, he completed the repair and had the system back online in no time.
I commend him on his technical knowledge, his ability to explain to me the problem, and his quickness to correct the problem.
