Today I had my Trane central AC XL 1200 (12 SEER) repaired. The repair person told me the unit was originally installed in 1989.
He repaired the unit, but eventually recommended replacing the unit with another 12 SEER unit. By installing a 12 SEER, he won't have to open the furnace if I selected a higher SEER?
Is 12 SEER the way to go verus a higher SEER
Is the XL13i 12 SEER?
Is the XL13i the best 12 SEER Trane model?
I am in northern New Jersey and use the unit 3-4 months per year.
Thanks for any info.
