Some states in the U.S. like Florida, Kentucky, Texas, New Mexico, and many others, will grant you rebates when acquiring a high energy efficiency A/C unit that meets certain conditions. For instance, getting a new A/C unit in Florida with a 16 – 17 SEER rating can make you eligible for a $150 rebate by FPL. You can look up rebates at your state in DSIRE or by asking your electricity provider.
