Replacing both aging units. Have quotes for Trane and Goodman. I can get 15.2 Seer Goodmans for the same price as 14.8 Tranes. Or even better, I can get 14.3 Goodmans for 4K less. Any opinions on Seer rating and up cost for the units. House is 22 years old. Any opinion on Goodman vs Trane. All units quoted are single stage units.
