[RFI] Interference from AC units

[Mel Crichton]

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....
