[RFI] RFI from new Hi-efficiency furnace?

[Mel Crichton]

Looking to replace old furnace with new 95% efficient unit. (Air conditioning won't be changed out as it works fine and no RFI)

I plan to stay away fom variable speed drive on the primary fan to avoid traditional RFI from VSD untits, but most all units have ECM (electronic control module) on the smaller combustion air blower. Some even have DC motors.

Any experience (good or bad) with these high efficiency furnace units? (RFI in or out?)  Looking at Carrier and brands made by Carrier  (Kenmore, Bryant)
