B. Carlson Heating, Air Conditioning & Plumbing, Inc. are far better than their competitors. I have used them twice. This last service call was to install saltless water purifying/softener system. The installation technician did tell me that it would take about a week for the system to adjust. What he didn't tell me was that the water would have a blueish tint to it, and I probably should not drink it. It did make me kinda sick. This wasn't a huge deal but I would have appreciated a little more detail about the water and what happens when it is first connected. The water is fine now and tastes good. I would use them again.
