Looking for the most economical way to improve the reliability and efficiency of your central air conditioning system? Turn to our Comfort series. With impressive SEER efficiency ratings ranging up to 16, they’re likely to cut your utility bills. And because these models can run even quieter than a common hair dryer, it’s easier on your ears as well. Some models in the Comfort™ Series may not be eligible for installation in the Southeast or Southwest regions of the country, based on Department of Energy minimum efficiency standards in place as of January 1, 2015.
