Care to expand on that concept, David? Remember the indoor unit is already
oversized, so intended to handle more refrigerant flow than the old,
inefficient compressor/condenser could produce.
AFAIK, a "high efficiency" compressor/condenser mostly produces more
refrigerant flow for the same power input ... are there other differences
I'm not aware of ?
And again, perhaps I'm out of date, but to my mind, changing a compressor is
a few $100, while a new system is several $1000. The EPA claims the
"average household" will only save $48/year by going from SEER 10 to SEER
13, meaning it will take a LONG time for a new system to pay for itself
solely in energy saving.
And who knows? Our government in it's infinite wisdom just might realize
that "ozone depletion" by CFCs is a hoax (though I don't think it's likely).
