[RFI] Window Air Conditioner Advice Wanted

[Roger (K8RI)]

I have a single window AC in my 28 X 40' shop.  I'm not sure of the 
rating, other than I went to Low's and told them I wanted the largest 
window AC they handled. It runs on 240 AC and easily cools the entire 
shop to 76F (on 95 + deg days) which has a 16W X 12H insulated garage 
door on the E end and an 8 X 8 insulated garage door at the W end of the 
S side.  Even with the big amp running.  It doesn't appear to add much 
to the shop's electric bill.
I'll try to find the ratings.

This is my second AC out there.  The first loaded up with the seeds from 
cottonwood trees plugging the radiator and cooking the compressor after 
abt 10 years.

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.

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.
