About Tri-County Air Service
A Local Team Committed to Comfort
Founded in 2005, Tri-County Air Service began with just one service truck and a mission to bring dependable heating and cooling solutions to families and businesses across Southern Mississippi. Over the years, we’ve become a trusted regional provider serving Hattiesburg, Wiggins, and surrounding counties. Despite that growth, we’ve stayed true to our roots as a family-owned business that values relationships, integrity, and quality workmanship.
Our focus is on more than just repairing or replacing equipment. We believe every service call is an opportunity to make someone’s day easier and their home more comfortable. When you invite us into your home or business, you’ll meet a team that takes pride in doing things the right way.
