I have know John for many years and trust him completely and I was not disappointed. John was great! I call him because I needed a new boiler. He called me right away and he helped me look at whether I should convert to gas from oil. I decided to convert and went with him recommendation to install a high efficiency combination gas boiler and hot water heater. John was able to come to North Jersey and install everything within 2 days. I highly recommend Delta to everyone. Thank you John!
