The day after Christmas, We got all of our kids back from their other parents' houses and getting set for them to see what Santa did at home and our heat is out. We needed a repair NOW. All of the part suppliers were closed, but Brett was able to talk to other people in his network and get the part and took care of it in one visit. To me, when someone has friends in the business willing to help them help me, that's the sign of someone with a great reputation. He was super friendly, professional, and got our Christmas back on track in no time. Thank you so much, Brett!
