"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."

"Jordan was very quick and did a great job installing a new furnace. Completely replaced the entire unit along with the air conditioning unit. Very friendly and respectful and answered all questions asked before, during and after job was completed. Very knowledgeable and explained everything in detail."

"Saxbee replaced our living room ceiling in our aging home with flair and panache, finishing quickly: he improvised solutions to two peculiarities of the ceiling--the weird angled corner on the southwest side, and the vents in the ceiling, and gave us superb trim that perfectly suited the room as well. Hard worker, cheerful and carefully listening to us. If you want a pro, go to Saxbee."

"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."

"Both times they came out. They were awesome and made sure the job was done right. We will be going to them for all our A/C and HVAC needs."

"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!"

"Installed air conditioner ,coil and furnace . Everything was done on time and correctly. The office staff are very nice when you call them."

"Tanner and Alycia were very pleasant and thorough in tuning up my aging furnace. Repair recommendations were made and reviewed. Chris arrived to price out options for a new system. He too was extremely knowledgeable and professional. I recommend anyone having HVAC issues contact Grapids."
