I now know why they have 5 stars. Easily my best repair service experience. I did my due diligence and called around to other recommendations from family and friends and figured that if the estimate was fair, I would stick with the local company just because. They came in as soon as they could, and were knowledgeable, courteous, and determined to figure out my issue quickly, since it was 5 below outside and my kids could see their breath Inside the house. We have an annual appointment now and I can't recommend them enough. Thanks Bob!
