[RFI] Ensuring an RFI free air conditioner install

[Steve Dyer]

I have a variable speed Bryant (same as Carrier) and it is RF silent, so 
I don't agree 100%. It also has an ECM fan motor on the outdoor unit and 
an ECM motor in the air handler. I couldn't be happier both with it's 
efficiency and RF silence.
That said, as a general rule Jim is correct. More people have had 
problems than successes.
My unit does have a factory filter on the AC line input and when I 
installed it Bryant factory engineer was keen to know if it worked. It did.
I do hope when I have to replace the compressor it behaves the same. 
Built by Litton if I recall.
Your best bet is to find an installer that will take you to another 
customer with the exact same install they are pitching and you can 
listen yourself with a portable setup.
I was lucky to find a really good HVAC guy near me that was amenable.
73/GL,
