Current Models of A/C, Coil and furnace are as follows:
Allegiance 10 7A0048A100A0 manufacture date 9/96
American Standard TXHC41A4H9A0 MFR DATE L32
What would the SEER rating be on this mismatch? what is the efficiency of the mismatch vs a matched ac and coil?
the AC is a 10 SEER, with the unit being 10 years old and mistched what SEER do you think it is running at. This will help be decided if a upgrade is worth it.
