[RFI] Window Air Conditioner Advice Wanted

[Donald Chester]

The window a/c in my shack finally gave up the ghost after 40 years of reliable service. I need a replacement right away, since especially with the station equipment running it gets too hot in summer to even be inside the shack without a/c.  Looking preferably for something with simple thermostat control and no hi-tech, RFI spewing technology such as switching power supplies,  pulse-width controlled variable speed motors and digital stuff that will likely fail after a couple of years. 

Around 20k - 25k BTU; the old one is 23k.  Checked local stores and about the only brands they have are LG, General Electric and Frigidaire, and not a lot of selection in the 25k BTU range.

>From on-line searches and product reviews, I have surmised that L-G units are very quiet and efficient but filled with the very kind of electronics that generates RFI.  G-E gets poor customer reviews with complaints of bad customer support and poor replacement parts availability.  Frigidaire gets the best customer reviews, but of course none of the on-line information on any of them makes even a fleeting mention of RFI.

It will be mounted in a hole in the wall about 8' high from the floor, so installation of a 130-150 lb unit will be a challenge, and the thing has to be reliable due to the near impossibility of pulling it out for servicing.

Any advice based on someone's recent experience?
