Kris P. Bismarck

“We built our ranch home in 2007 and we have never been happy with the heating/air-conditioning system out there. When the thermostat was turned on in the apartment above the garage, it would regulate the right side of the upper level of the main house. The initial Heating & Air contractor had definitely messed up when installing the system. They were out there many, many times and it never got better. The worst thing was the loud high pitched whistling sound that came on in the main home upper bedrooms EVERY time the system kicked on. Over the years, we’ve had other AC contractors out there and they didn’t help either. I asked Kel if we couldn’t have your guys TRY to see if anything could be done when you were out there installing the ground work for the addition. Thank God, your people knew what they were doing. I know that they couldn’t change the installation problem but guests can now sleep comfortably upstairs. I just wanted to tell you that your technicians did a great job. Thank you so very much. I wish we would have had you years ago. “

“Dear Northern Plains, I am writing in order to tell you how pleased I was with your service. On Thanksgiving Day, our furnace in our house went out. Chris was on call for you and came within a reasonable time. He was friendly, helpful and informative. He taught me a lot about the furnace we have and I am very thankful. I pay special attention to qualities possessed by individuals which are so important for leadership. Chris has those in abundance. Now, I certainly have no stake in Northern Plains, but I wanted to write for two reasons, 1) to thank you for such great service with your person on call, Chris, and 2) to let you know that this is the type of person who is perfect for management, should that opportunity ever arise. As you well know, morale goes from the top down, not from the bottom up. Thanks again.
