“We had our air conditioner go out at the worst possible time. A huge heat wave right before July 4th. After calling a few businesses DG was able to get us an appointment two days later which was much sooner than anyone else. They also said if a technician had an opening they could possibly see us same day. Received a call a few hours later and Brandon came to the rescue. It was a relatively easy fix for a professional and we were up and running within an hour. Life saver. Brandon was thorough and good at explaining what happened to my wife and I. We really appreciate the help and it's very settling for us to know that we will get through this Summer sizzle with our cooling system working. thank you.”
— Mark Grimsrud
“Furnace pilot light was out and since it was installed a few years ago by DG, I called them for service. Brandon came and he fixed the issue quickly, and explained things clearly. Overall happy with the service.
It's worth mentioning that the installation (also remove the old style one) a few years ago was not an easy job, they had to open up the floor to remove the old one (installed in crawlspace) and also put exhaust pipe through roof. All was done in one day, with permit issued.”
