Kyle was very friendly and informative. He was very knowledgeable of the system and completed his cleaning quickly and thoroughly.
Kyle Daniel arrived on schedule and promptly began the furnace replacement job. He was neat as he removed my old furnace and replaced it with a new one. When it was finished he reviewed what was done and made sure my questions were answered before he departed. That's the kind of person I want servicing my account!

Daniel I have a rental property in Nazareth and last week, when the cold weather came to the Lehigh Valley, my tenant called me at 6:15AM to tell me they didnt have hot water or heat. My tenants just had their first baby three weeks prior so my goal was to get this back up and running ASAP! I Called Deiter Brothers answering service and the lady on the phone was very polite, got all of my details and even confirmed the phone number and spelling of my name. Within 30-Minutes I had a technician call me and tell me that he was going to be leaving for my place within the next five minutes. I asked him to please reach out to my tenants to ensure it was a good time for them (remember, they just had their first baby and I wasnt sure they were getting any sleep). To my surprise, he was totally okay with it. I expected a grumpy person because they were called out of bed earlier than they had expected but nope! This guy was very respectful and willing to help in anyway. I had a great feeling about this. Within an hour he had the problem identified and quoted me a price. Then I asked him how fast he could have the part and get the furnace up and running. At first I thought I would get the normal story of how he would need to order the part and come back nope! He said he had the part and would have it completed once I gave him permission to do so. When he was done, he called me to let me know all was up and in good working condition. The tenant had heat and hot water. He also said he cleaned up after himself which I thought was such a plus! Later that day, I called my tenants to make sure all was good and they raved about how respectful he was while on site and how he worked as quietly as he could so as not to disturb the baby. I could not be any happier with their service crew, from the people that answered the phone to the technician that made the repair and if youre having issues or if youre looking for an upgrade consider reaching out to Deiter Brothers in Bethlehem, you wont regret it!
We are very happy with the service we received from Deiter Bros. We just had a new ac/heat pump installed. Charles gave us our quote and he was very thorough, polite, and informative. Dan and Ryan were very professional, clean, and courteous while installing our unit. I will highly recommend Deiter Bros. to everyone I know in need of HVAC work!
Excellent customer service all around. Starting with the the customer service rep in initialing getting someone out - very nice and accommodating! CARLO was awesome! He was extremely pleasant and I felt as though he treated us as if we were family. Very kind, considerate and took his time in coming up with a couple different options for us. Due to the age of our boiler, we opted to get a new unit and he then looked into getting us electric heaters to use until installation. CHARLES came out the following day and we received the same quality of service - super nice and pleasant and looked for the best price. Would highly recommend this company!
