We were in Colorado and our A/C went out upstairs. We called on a Saturday and Pete came out and we needed to replace the unit. Alex S. and Alejandro came and installed a new unit. This was not easy because they had to get in the attic which has a small opening. Not only was the house hot, but the attic was worse. They did and EXCELLENT job and even fixed things that the original builders did wrong!! This is the way the units should have looked with buying a new home!! WE definitely recommend B. Carlson!!
