So that's what they do up there (the Johnson Controls, nee York, nee
Westinghouse plant is here in Norman).

I have a WaterFurnace Envision and I don't hear it.  Or at least if
there is RFI, it's not enough to bother me.

I hear my Whirlpool Duet washing machine (oh, do I hear it).

But the heatpump is quiet.  Looking at the specs, though, it seems to
have a variable-speed fan.  Maybe they shield?  They have extensive
documentation on their site if folks are interested.
