I just purchased a new house with a carrier Heat Pump. I have the following model #'s Outside-25HBA360 Inside - FX4CNF060. Can someone confirm the SEER rating and size of these units together for me? Everything I read says the 25HBA360 indicates a 13 SEER 60000 BTU (5 ton unit). There is a sticker on my AHU that says this unit is 14 SEER (which is what i bought) does the combination of units Equal a 14? Also I know to do this right calculations must be done but house is 2800+ SF with lots of glass east and west living in central florida. Does this unit seem undersized? Thanks for all your help!!
