"Jim and his assistant showed up on time as usual, went to work and got the job done thoroughly with no issues.  He explained where I had questions and made sure that I understood.  This was the first cleaning of this home in 35 years and I'm confident the job is done right.  I've used his services in my rental property and in this case insisted that my builder use him only.  No problem there, those people already use Duct Works as their standard vendor!  
These guys are really good and I'd never use anyone else!

"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."

"Best decision we made was getting our air ducts cleaned by Air Care of West Michigan. John was amazing from the start. Very thorough and a hard worker. Would definitely recommend!"

"Hired JT to install central air into our home. He was very polite and professional throughout the installation. He took the time to explain the process completely. The install went flawlessly, the work area was cleaned up better than new. Any questions my wife had after the installation were answered promptly and professionally also. Highly recommended, will definitely use his company for any future projects."

"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."
