Called 2 different heater companies to come services my unit on the roof and neither companies would use a ladder to get up and see what was going wrong with it. I called DNA and they sent 2 guys to use a 40ft latter and they had my unit working the same day so we didn’t have to stay at my mother-in-law‘s place again. They were very kind and professional and were very affordable.
