Had a York 2 ton all in one (AC/Natural Gas heat) unit installed a year
ago. Has variable speed motors. I dreaded the RFI possibility. At the
time though other priorities necessitated getting one as quick as
possible and nearly all I shopped for had variable speed motors.
Fast forward, no RFI detected from it. I could spit on it sitting here
in the radio room if not for the outside wall :-). Only thing I hear on
the rigs is when the natural gas ignitor kicks on for a second or so.
Guess I got lucky.

Fixed speed blowers do not usually create RFI.
They come on when needed to a preset rpm, shut down when no longer needed.

Hi Guys,
I've seen posts where some Air Conditioners and Furnace units with
variable speed motors create RFI on the Ham Bands. I'm thinking of
purchasing a new Carrier 3.5 ton Heat Pump, Model 25SCA542, with a
"fixed speed" blower and am wondering if anyone has had RFI issues
with these? Thank You in advance for your thoughts. 73, Dick- K9OM
