After having four different HVAC businesses provide estimates to replace the AC/heater on a mid-size home I selected Interstate. Turns out to have been a very good decision. Moderately priced for a new Carrier system. Work was scheduled quickly and office kept in contact with me by phone and text to let me know when technicians would arrive. Techs were on time, personable and professional and completed the work in a single day...on the hottest day of the year in OKC. Techs worked efficiently with minimal disruptions to the home and the new system looks great with all of the work appearing tight and clean (the unit itself as well as all the lines and connections). Hauled away all of the old stuff so there was nothing I had to contend with or dispose of myself. A great job all the way around...cannot really think of any improvements. And, of course, the new system is performing superbly.
