    Air flow restriction?

    If you were to slide your air handler filter (5" thick filter) out about half way and let go with the system on first stage heat (HP), and it sucks back into its slot, would you say that's a problem?...

    No, it's the opposite. The system needs to extract as much heat as possible from the coil. The strip is DOWN stream of the coil.

    False advertising?

    Tecman, that doesn't make sense... Shouldn't the refrigerant come out of the compressor (and into the desup) at about 130* pretty much year-round?

    You mean besides the huge difference in heating cost? Heat pumps put a lot more heat per dollar into the home than either gas or electric.
