An Outstanding Job by Your Technicians

Your Technicians are well qualified and do an outstanding job. Customer satisfaction is their goal. Of course, I was well satisfied and could not have had a better quality product put in my home.

Technician was Kind and Knowledgeable

Josh was professional, considerate, and polite he treated us like family. He didn’t want to leave an elderly disabled veteran without heat and didn’t want to leave without doing everything he could to get our heat up and running. He was sensitive to our needs and answered all our questions. We wish all technicians were this knowledgeable and respectful and kind. If possible thank Josh again for an excellent job.

Amazing Technician

Tim was fantastic…give that man a raise…and I am not just saying that because I am a former employee. Usually when they inspect my furnace/ac I am not home so I don’t really get to see what they do. Tim checked not only my furnace but also gave me advice on the water heater, benefits of a humidifier and advised me on getting new smoke and carbon monoxide detectors for my protection. I appreciated all of his recommendations and his concern for my safety and comfort. A real benefit to the Detmer team!!
