We're homeowners, and we're this close to picking a residential AC unit, and have one more question for you: After looking at every conceivable 3-ton, 13-seer, residential AC unit (and inside coil), we think we like the Carrier comfort line.
So, a salesman in our town who sells Carriers told us that he has older units of Carriers. He said, "Why do you think you need a 13 seer? We have 10-seer units to sell, for less." The warranty is only 5-year on compressor, but the price is pretty good.
What do you guys think--is an older unit (a couple of years old) 10-seer unit ok? Any advice is welcome.
