Jose was on time and completed his work promptly. He explained everything he did upon completion.
Jose Colton was great; Professional and detail oriented! He took the time to answer my questions about the bouler cleaning and was very courteous. Thank you Colton!
Colton Returned phone call promptly. Good to speak to a human rather than a automated answering machine early this morning when my furnace wasnt working.

The technician who came out was polite and courteous. He explained what he had completed in detail. He made sure I understood and was satisfied with the service. I was very happy
Colton He was very pleasant and so efficient. The service was done quickly and without any issues. Thanks for a great experience and team member
Jose Water heater broke down on Sunday, day after Christmas. Made a call and they were here within the hour. Fixed it and good to go. Great to deal with
My tech's name was Anthony, but he wasn't on the list of choices in the beginning. He was very professional, very friendly and I enjoyed talking with him. I have always been happy with the service I get from all the employees of Dieter Bros. The only "constructive criticism" I would offer is that I very rarely receive my filter for my system -- while I know I have an odd size (16x20), I always mention it when I schedule my service but the techs never seem to get that info and don't have one. It's minor, and I keep a supply on hand, but it is supposed to come with my service plan.
Joe was wonderful, and Lorri and Amy have been incredibly kind and accommodating. So far my switch to Deiter Bros has been professional and smooth and I'm feeling very positive about working with you all! Happy Holidays!
Joe always happy with Dieter Bros. service. Always on time, very professional and effiecient. Employees are very courteous.
Very professional and taught me the basics of maintaining my system and how to prevent problems before failure and how to save on energy costs over time. Basically, change my filters.
Terry Excellent customer service from my first phone call until the job was finished. The technician, Daniel, arrived promptly (as scheduled) and addressed the problem (oil boiler /circulator) completely. He was respectful and friendly, and patiently answered all of my questions. Excellent experience, as usual, with Deiter Bros.
Jeff from Dieter Brothers did our annual Service on our Buderus Boiler. I told him @ issues we had at the end of last year and he checked everything out and replaced some parts etc. He was very professional and explained everything he was going to do. Please send Jeff back next year too! Thank you
Initial booking took a while, but they went through everything thoroughly once here and were willing to explain everything to me, which was great as I had never owned a boiler before.
Patrick was efficient, checked what has to be done to remove oil tank. Explained what would be done to remove tank. He was very friendly. I was pleased Deiter Bros would remove the tank as it was left here when previous owner switched to gas heat.
Friendly and professional service tech did an awesome job. Found the problem and repaired it, quick and efficient. Thank you again!!!!
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
