I have a 1 story home with basement. Square footage is 1050 feet. I have triple-pane storms, extra insulation in the attic, and live in Kentucky (moderate climate). I am getting estimates for new furnace & a/c. I have already decided to go 14 SEER with the a/c, but have gotten comflicting opinions on compressor size. 1 contractor's bid was for a 2 ton unit with 2 1/2 ton coil. The other 3 contractors bid was for a 2 1/2 ton unit with 3 ton coil.
My current system is a 1977 Carrier, 2 1/2 with 3 ton coil
and does a great job, but I have recently had a minor repair done and feel it's time for replacement.
Price difference is of no concern, but I would like opinions on what size unit would best fit the environment of my home.
