[RFI] HVAC

[Gene Smar]

Dan:
I replaced my heat pump last year and made a similar inquiry here. What I learned is that the "variable speed" fan controllers typically are the RFI instigators. The microprocessors in them are the source of noise.
On the other hand, "multi-speed" controllers operate at discrete fan speeds and are less likely to generate RFI. I decided to go with that type of controller for my new heat pump system. So far both AC and heat apparently have been quiet for me.
My installation is a Goodman brand, FWIW. Good luck.

EMIis a great concern. It's a small house and efficiency is of little
importance.
What are the recommended brands and/or models?
