Resurrecting the old thread as I am faced with the same dillema
Carrier Infinity offers several different models, 59MN7C (top of the
line) and then 59TN7A, 59TN6 and 58TN0B being a two stage.
There is also another set of models falling under "Performance Series"
Does anyone know if all these models have the RFI filtering included ?
EG Quiet RFI as described below.

My brand new Carrier Infinity HVAC system is totally RFI quiet. Multiple adjustable
speed drives. Except for the big compressor, the drive electronics are integrated into
the motor housings, eliminating many likely RFI radiators. There’s a HUGE board
full of L, C, and ferrite chokes at the power inlet to the compressor. I have to hand
it to Carrier, they did a thorough job. I have to walk right up to the equipment with
my DFing antenna to detect anything. If there was a problem, I noted that there is
room inside all enclosures for additional custom filter components. Photos available.
Also a big Bryant mini split was just installed at N6RO. I had previously been taken by the
contractor to an identical installation to check for RFI. Nothing detected! Same for the
Mitsubishi mini split at my remote station, where it sits right under all the antennas. This
is all good news… I’m beginning to think that the major manufacturers are doing
the right thing.

I have a 20 year old forced hot air, gas furnace. Still working fine, but
it will need to be replaced in the next few years. I would also like to add
A/C to the mix.
Anything new in that area ? There is a great presentation at
https://viennawireless.net/wp/wp-content/uploads/2021/09/HILLSON_RFI_PDF_3SEP2021.pdf
or https://www.youtube.com/watch?v=vj-14H-HpFU , but I have seen very
little recently. Have any of you installed new HVAC recently and dealt with
RFI ? Good or bad experiences with installers and manufacturers ?
