Southern Air installed our inside unit Nov, 2008, and we were amazed with everything about them! When we needed the outside unit this year, we asked them to install it. They just left, and we wish we could tell all of North Texas that you would be doing yourselves a huge favor by using Southern Air. After trying 3 others, we know we have found honest, efficient, considerate, and GREAT people that we can count on and trust. THANKS, Clint, and ALL at Southern Air! We really appreciate you!
