Recently I contacted a couple of A/C system installers in my area regarding the
possibility of RFI to my HF rigs.
One didn't have a clue waht I was talking about, the second promised all kinds
of dollar savings and such along with no worries about RFI. When I politely
asked him to put that in writing, he not only declined to do so, but also added
that this boss had told him to stay away from that subject.
Won't go on about my suggesting that his boss may already be aware of noise
interference, but did notice that as the conversation wore on, he seemed to
gain more anxiety towards leaving our home.
Both were Trine equipment dealers.

Subject: Re: [RFI] Interference from AC units
I did a lot of research on air handlers (and posted here) before I bought my
95% efficient Carrier furnace last year. Although you are looking for a
replacement condensing unit (not an AHU), Carrier might be a good place to
start. There was lots of flack regarding Trane's high efficiency AHU and
there may still be concern with the trane line. The problems seem to center
on variable speed motor drives that increase efficiency (and cost) but may
also line you up for a tax or utility company rebate. My carrier AHU has
such a drive but it's RF quiet.
Check the archives of this discussion group ... a lot of good
recommendations regarding getting RFI issues settled BEFORE purchase....
