I had Zenner and Ritter come out for duct cleaning. Brandon and Scott were very professional and thorough. They answered my questions, explained the process, were very neat and did a great job with the tools they had. Unfortunately my expectation was not met. I was very disappointed with the results as I knew there was more to be cleaned. After several phone calls to Z & R, and research on Brandon's side, Zenner & Ritter recognized that they needed to change things and to make things right with me. They purchased additional equipment and re-cleaned my ducts at no charge. Brandon and Scott went above and beyond to ensure I was more than satisfied with the results, which I was. Thanks guys! With this new equipment, I am happy to recommend Z&R (Brandon and Scott) for duct cleaning. Brandon and Scott take Customer Service to a new level.

Kyle Mahoney, a technician from Zenner & Ritter Service Team came to my house after hours to fix emergency heating problem. The problem was fixed in a very short time, of course all credit goes to Mr. Mahoney who did an excellent job to resolve the heating issues in my house in a professional manner. I would like to rate his performance "Outstanding". Great Job! I wish Zenner & Ritter Service Tech a very happy new year.

December 29, 2017 Needed maintenance on my furnace which I had bought from Zenner & Ritter. Technician Kevin Ring came to my home within the expected arrival time and diagnosed the problem and after retrieving the parts needed to resolve the issue he quickly went to work. My furnace is now working great! Thank you Kevin! Melissa

The text messaging and call when technician was on his way kept me informed. Dan M was very polite and informative. Advised me of maintenance that I should do to extend the life of the furnace.
