"Travis Walton was wonderful. Such better service than the larger companies. His first aim was to repair if at all possible. We had a much larger company in last time and all they seemed interested in was replacing the whole unit. Finally, a person we can trust. Excellent work! Call me anytime. We really like this guy."

"I am a new customer with Service Professor, Inc. as of May 2021. In each of three service calls for routine system checks of my HVAC, plumbing, and furnace systems, I couldn't have been more satisfied with the professionalism of the individual tradesmen or with the customer service communication provided by friendly and patient office staff. This review is being posted especially to praise the exceptional routine service call provided by John Courtney on 10/11/2021. John presented as being a good listener and one who genuinely enjoyed his work and serving others. For example, he listened carefully to my questions and responded with detailed information that I could understand easily. And, after I commented to John about my previous positive interactions with Service Professor, Inc. tradesmen and with customer service staff, John responded by stating he has worked in the heating and cooling trade for 12 years and felt very fortunate, as a newer employee, to be able to work for an organization such as Service Professor that places caring and quality customer service communication among its most important priorities. I hope my comments encourage anyone seeking HVAC, plumbing, or furnace routine service or repair work to not hesitate to contact Service Professor."

"We hired Alan recently to re-drywall part of our basement that needed to be re-finished after having some water issues during the heavy rains last spring. The wall looks great, and Alan did a great job. He was good to work with, fair on price, got the project done in a timely fashion, and we would use his services again."

"They've maintenanced my furnace before I required a new one and they've always maintenanced the new one since I got it replaced about 3 years ago. Very easy to work with. I think I've been using them since 2008."

"The two men were available to do the job the very next morning. I was afraid I was going to need a new central a/c unit. The guys went right to work and in less than an hour had my a/c up and running for under $100. I was extremely pleased!"
