This is indeed becoming more of an issue.

I recently replaced my furnace with an American Standard 95% efficient model
with a variable speed blower.  I was concerned about the blower, since it
uses a DC motor with electronic drive circuits.  Of course there isn't a lot
of information to be had about RFI on these kinds of appliances up-front.
So I held my breath and crossed my fingers during the install.  In this
case, I can report good news - no detectable noise from the furnace from 160
thru 20 (only places I've checked).  I could probably live with a noisy
washer (I don't do laundry during contests ;>), but it is nice to have heat!
