Rob serviced our AC unit on July 13th, 2016. Sorry for the delay for this review, but our electricity went out in the storm on the 13th and we have just gotten it back. We could not ask for a better service provider than Rob. He is friendly, but also very professional and knowledgeable. I usually have a lot of questions for him, so I have to add that he is very patient as well. We trust Rob with all of our HVAC needs and we recommend him to all of our family and friends.
