I had a great trip to Indianapolis today with the Temperature Systems, Inc. Dealer Advisory Council for a Carrier Corporation factory tour. The day was filled many insights and great discussions with program managers and engineers. Thank you to those that took the time out of their day to talk with us. A special shout out to the Carrier plant employees for making the best products in the HVAC industry! - Sean
