Extremely proficient and thorough. Personable and professional explaining all. Recommendations for further efficiency offered by Deiter Bros. We're very pleased.....as usual!
Gabriel took all the time he needed to look over my heating system; and when he was finished he took more to explain to me everything that I should be looking for and things I could be doing between visits.
Gabriel Deiter Brothers scheduled their visit to meet my timing needs. Vinny had his hands full analyzing my ‘no heat’ situation and once he had it figured out he tested and retested to make sure I wasn’t going to have another issue. He gave me a good description of what was causing my problems with my oil furnace and the thermostat. He took his time explaining what the problem was and made sure I was comfortable with the explanation before he left.
I had a schedule furnace service check appointment and received a text that the technician was on his way. The appointment was for between 8:00 and 9:00 and he arrived promptly at 8:00. He performed the service check, informed me everything was working properly, and left. Everything was neat and clean when had finished. I have been with Deiter Bros for decades and they are always professional and prompt.
Miguel came to the house today to do the annual maintenance on our furnace. He is very knowledgeable of our system, he was clean, friendly and did a great job. Keep sending him each year. Thank you.
