We have established that I need an additional .5 ton of cooling for my upstairs attic space (finally found someone to help with Man J).
I currently have a 12 seer 1.5 ton condenser with a 2 ton coil, both are about 5 years old. The contractor I like the best says I should replace both condenser and coil with 2 ton 13 seer unit, and he's probably right. But could I keep my current 2 ton coil, right size piston, and use a new 13 seer 2 ton condenser and have a system that will last and cool just about as well? Thanks
