About Del-Air Mechanical
Comfort Has Been Our Career for 39 Years!
For over 39 years, Del-Air has been serving the greater Knoxville and East Tennessee markets as an unlimited licensed mechanical contracting and service company. Dwane Lay started this company in 1980 with little money, one service truck, and an unmatched determination to succeed. Today, with more than 150 full-time employees, Del-Air Mechanical continues to grow while maintaining the honesty, integrity, and professionalism with which this company began. We remain focused on our customer and employee needs.
