I’m in the business. So that being said. It is critical the system is sized correctly. Code requires that be done(manual J). To large humidity problems. To small not enough heat transfer. . 

As far as RF interference can be a problem with the Variable speed units no matter who the manufacture is.  A couple of large ferret rings (chokes) to the power lines to the blower motor seems to work. 

Good luck

The time has come to replace my 19 year old air conditioner at the house. 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.
