I am replacing my Goodman AC unit that lasted total of 6 years...
I am debating between the below 3 units, could anyone know if the benefit is more than the cost? Here is the SEER and additional cost that I got quoted.
XB13 = 13.5 SEER
XB14 = 15 SEER / $ additional to XB13
XR15 = 15.5 SEER /$ additional to XB13
Which one you guys think I should install? I live in Maryland BTW.
