We have used B. Carlson Heating, Air Conditioning & Plumbing, Inc more than once, and they're great! They do what they say they're gonna do, and their techs are very friendly and knowledgeable. We've had them replace three things in our home, and recently had them out to fix an equipment issue. Something was messed up with one of the pieces of equipment that were installed, but they came out in a timely manner and got it taken care of. Hopefully, we won't need heating and cooling services in the future, but if we do, we'll definitely reach out to B. Carlson again!
