I live in Corinth, MS and recently used Harbin Heating & Air Cond. Inc. These guys are very professional in every way! They came to my house and checked everything out, talk to us about what was in our budget, and gave us 3 different options that we were allowed to add or take away from. We got exactly what we wanted and have been extremely satisfied with the service. Best of all, the new unit has cut our monthly bill in half!!!! 2 THUMBS UP!!!!!!!!
