    My contractor gave me the following model number - but he did not specify what efficiency rating for the coil.
    If someone could lookup the efficiency of Trane Indoor coil TTXC036C4HPC? I'd appreciate it.

    thanks in advance

    It depends on what outdoor unit it is matched with, and what type of blower and how much air flow the indoor unit is producing.

    Indoor coils don't really have a size or efficiency by themselves.

    That particular coil could be matched with a very wide range of outdoor units from 2 ton through 3.5 ton units.

    It is generally considdered a "standard" efficiency coil.

    If more government is the answer, then it's a really stupid question.

    if matched with an XR11 will I get 11 SEER or 10?

    another post by BaldLoonie on a different thread seemed to suggest that I will only get 10SEER
    I'm guessing TXV is variable speed - so I will get 11SEER only if matched with a XV? if not I can expect only 10SEER right?

    here is my furnace:
    TTUD100C936K
    and here is the heatpump

    I just noticed in one of your other threads you mentioned a 3 ton XR11 heat pump and a 100k BTUH XR80 furnace.

    That coil with the 3 ton XR11 heat pump would be 10 SEER.
    Adding a TXV to the indoor coil would bring it up to 10.5 SEER.
    With a XV80 furnace and an indoor coil with a TXV, that system tops out at 11 SEER.
