We hired B. Carlson Heating, Air Conditioning & Plumbing, Inc to do various types of work for us, and they have done them well. They show up when they say they will, and never leave a mess after their job is complete. I always ask companies to call before showing up, and the techs from B. Carlson always do just that. If I remember correctly, I last had them out to install a new hot water heater for me. The workers were very nice and everything went very well. I would definitely use them again.
