Allen, most all AC units now use ECM motors for the fans (condenser & evap) most of these produce some type of RF. The older PSC motors did not. I looked at your neighbors AC (K5BOU ) several years ago as he had noise wiping out a part of the 10m band. I traced it to the condenser fan motor. The unit originally had a PSC motor but late in the manufacture they installed a ECM motor. ( it still had a duel cap in it but only the herm was used). Still only a 1 speed unit. But had a ECM motor. Most have gone to ECM motors to meet energy requirements, although the savings are very small on a single speed unit. As far as brands go, many are made by a few co and sold under different names. ICP owns Carrier, Bryant Airquest, Arcoaire, Comfortmaker, day&Nite, Heal,Keeprite, Tempstar. Ingersoll Rand owns Trane, American Standard,( made in Tyler TX Daikin owns Dakin, Goodman, Amana, Janitrol, GMC. ( Dakin AC made in Waller TX) Johnson Controls make York, Colman, Evcon Rheem owns Rheem, Ruud, Friedrich, Weatherking Surecomfort. As far as the difference in a 17 & 20 Seer In the end you will not save much with the 20 and they have more stuff that fails. I like Trane,Daikin,Rheem in that order. All make OK systems, most all have a no frills brand Carrier, Bryant. Rheem, Ruud Daikin Goodman

I am considering the choices of 2-speed vs. variable speed. Has anyone out there had any bad experiences with variable speed AC units generating RF noise interference, what you did about it if you had it, what brands are good vs. not so good on this issue? Also looking at 17 SEER vs. 20 SEER.quite a price difference. (My old one is 13 SEER). Any input would be appreciated. 73, Allen R.
