I own an older house with a hot water heat system and I am want to get a Split AC system installed. The setup involves 2 9,000 BTU units, one in each 2nd floor bedroom and a 12,000 BTU unit on the first floor. I am on the fence between the Bryant Legacy system and the Evolution system. I would feel better about paying a premium for the evolution series if I could figure out the difference in efficiency. But I have not been able to find out that information. Both quotes point to the same condenser. So if the difference between the two is based on the condenser, than I might as well go with the cheaper quote. The more expensive units are quieter, but compared with a window AC unit both quotes are going to give me quieter cooling. Thanks.
I added the quote for the split ac units in case anyone is curious.
