    ok they say condensing sat point is up to 30 degrees over ambient. but lower for the higher SEER rated condensors. how do you know what the seer rating is of the condensor your working on?

    the nominal seer is indicated in the model number if you know how to read it. otherwise you would need to consult some other literature. the system seer is determined by the combination of equipment and can be found through the AHRI directory. To my knowledge there is no universal rule taht sais the temp diff between coil and outdoor air should be X for a given seer rating. I would think it would have to depend on the manufaturer.

    Not all manufacturers have the SEER rating in their model number.

    Forget about that X over outside ambient stuff for now. And use SC and SH to determine if a system is charge right, and or working right.
