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
Ryan did a great job on our bi yearly preventive maintenance. He explained everything he was doing, checked everything, and even fixed the vibration sounds in our outside unit. Really nice guy too! I couldn’t be happier.
Alex is courteous and knowledgeable. He performed maintenance on my HVAC and solved a thermostat problem. I’m highly satisfied with the results. He’s an excellent asset for Deiter.
Ryan has been at my home twice in the last month. He is very likable and competent. What impressed me most is how clean he left the workplace after completing both jobs.
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 He explained everything and really took extra care of my unit. I appreciate Dieter Brothers, keep up the good work and these friendly employees. When I get a simple, NON condescending explanation, it speaks volumes of the character. Thank you
Ryan 
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.
