Hansen was recommended to us by friends when we needed help with a furnace installation. In October 2020, Ryan and Olivier reinstalled a new furnace for us when the original company we hired left us with a shoddy mess. The work they did for us was professional in all regards and the finished project passed inspection with no trouble. A few weeks later, Ryan returned after hours, on a freezing cold night, to repair a small problem and save us from a night without heat. Hansen provides excellent customer service and we would certainly deal with them again and recommend them to others.
