“We have used Northern Plains multiple times in the 10 years we've owned our home. Heating/AC issues, new water heater, and just today, fixing a leak in a corroded pipe. The technicians are always very nice and explain what they're doing and why very thoroughly. Couldn't be happier with our service over the years.“

“Pretty tight getting a 53ft trailer in here. Advice to drivers if you have a 7am delivery arrive a bit early or pull down through the driveway to the left and back in off the street. When it fills up with customer vehicles it is tight even with tandems forward.“

“We needed smoke smell removed from a home we were listing. They did an amazing job, had it set up and running all night and completed before our open house the next day. We were a small job and it was our first experience with them but they treated us like we had been doing business with them for years. Would highly recommend them for big or small jobs.“
