Patrick Patrick, from Dieter Brothers, was very thorough in evaluating and determining the problem with our water heater. He took his time in explaining everything he was doing. Not only did he make me feel he was a professional who actually cared about our problem, but he completely cleaned up the work area when he was finished.
Justin did a great job installing a WiFi thermostat. He is knowledgeable, courteous, friendly, and helpful. Very pleased with his service and with all the people who work at Deiter.

Justin is extremely knowledgeable, patient and professional! He is our choice to ALWAYS service our furnace!
Justin Kyle came to check our air conditioner blower which continues to make an awful lot of noise. He checked the entire unit to assess the problem. We need a new motor. Kyle was friendly and professional. He is ordering the part for installation. Thank you, Kyle and Deiter Bros, for your quick and efficient work. This is why we have been your customer for many years.
My wife and I recently moved into a new house and the furnace and ac really needed some love. The tech that came out to my house was Jeff Dillensnyder. He explained literally everything he was doing in a very customer friendly fashion (I'm not an HVAC guy). He was very friendly and respectful. He also was very direct about what the issues were and what needed to be done now and sometime in the near future. Overall, I was very pleased with my service and would highly recommend Jeff and Deiter Bros for any future HVAC needs.
Justin did exactly what I was expecting ,to remove and stabilize old piping. He worked efficiently and really cleaned up at the conclusion of his work. Friendly and effective. And Deiter Bros price was very reasonable. I'm very satisfied.
Karlo did our annual furnace cleaning today. Karlo did an excellent job. We anticipate that this coming year -- like our prior four to five years -- we will have zero calls to Deiter Bros. for a "No Heat" emergency.
They always are respectful and knowledgeable. Ive been with them for 55 years and always recommend them.
Great service. Jeff D was professional and polite, worked with urgency, had a quick diagnosis, and happy to explain the situation in detail.
All of the service techs that came to house were always friendly and very helpful. They showed up on time every time and never had to make me wait. Thank you !
Our technician was prompt, polite and efficient even in the high heat and humidity. He really did a nice job. Thank you
