Arctic Wolf installed a humidifier to our furnace. I chose Arctic Wolf due to the great feedback they have received on this site. I left a message with the company and received a call back within the day. Robin was able to fit us in the next day to do the install on the humidifier. He was professional, did a fantastic job and explained everything to us when he was done. I would highly recommend Arctic Wolf to anyone. We were definitely pleased with their service.
