Service Tech was very knowledgeable, respectful, kind, pleasant, performed maintenance as required and requested. Very respectful to my home and property as well.
Alex came to our home this morning. What a delight to have him in our home. Thank you, Alex. Although he was unable to correct the problem today, he assured me he would return at a later date. I trust Alex will return, and all will be resolved.
Vinny has come to the house twice and both times he was clean and efficient. He answered all questions and made sure I understood the work that was taking place that day.
Technician is of the upmost courtesy and very affable most importantly it was technically knowledgeable about the system 2000 that he was there to work on five stars
We were very pleased with Vinny. Worked on our AC unit, located the problem with the vent & AC is working. He is also a very personable guy. I’d also like to give kudos to Joe who came out the night before. Also, very personable. In fact, everyone I dealt with at Dieter Brothers has been very helpful.
Prompt, professional, very efficient, willing to answer any questions I had and mostly, very friendly. I am very happy with the service he provided from start to finish.
We had not used our Air Conditioning this year which resulted in an initial low pressure reading. However, Raymond caught that the pressure came back up to normal as the system ran longer. Therefore, we didn’t need a costly freon addition.
Raymond 
Very professional and thorough. He was very knowledgeable and addressed any problems. I t was a great service.
Gabriel was here today to do a maintenance check on my furnace and air conditioning unit. He always gives 100% . I'm always satisfied with the service my family is given
Nick was great. Fixed the issue immediately and was so kind and understanding. Many thanks to all at DB for all your help and resolving our issue.
Nicholas I had my Ac unit serviced today by Ryan Skoutelas , professional, courteous, very Knowledgeable of the job to be done. He cleaned up the area & left it immaculate. Highly recommend this company & Ryan.
Vinny was very good in explaining how the thermostat operates and set it so I won't have this problem again.
Vinny Joe knows our home’s idiosyncrasies! He is professional and courteous, respectful of our home. We’ve replaced our HVAC systems, converted from oil to gas, had a full house generator installed and replaced a heat pump-all by Deiter Brothers! Joe has been on site for it all! High marks for Joe Laubach!!
Joe He completed the work thoroughly, taking his time to clean up after working in the two locations. He explained the need to replace something in the outdoor portion of the system and showed me the ‘test’ score.
Gabriel Gerry and another person (I didn’t catch his name) were very professional and did a great job removing my 500 gallon tank and replacing it. I highly recommend Gerry and the team at Dieter Bros.
Gerry I have used the Deiter Bros for the installation of my Generator and propane tank, along with service calls, the Techs are always very cordial and competent and get the job done! Highly reccomend them.
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.
