If you re-read what the OP asked, he wanted cheap. He ruled out VS and unloading due to cost. He then suggested tempered supply air...which to me sounds a lot like reheat.

Could one pull some r22 out enough to knock off let's say 20-30% of the cooling effect w/o causing other troubles?
I have a situation where high solar load makes for terrible comfort issues when the system cycles where the temp swing up on the off cycle equals immediate discomfort.
Basically I think at least in all but the hottest summer conditions we’d be better off with tempered S/A and longer cool on’ times. (A hundred sq ft of south exposure glass per room at 110 degrees, 65 out side ...
How about a smaller compressor? Oversized coils seem to be the way to go. Or am I missing some vital logistic?
Now that ive pondered it for a bit could we actually increase efficiency with a smaller compressor? Thats about what the manufactures have done, decreased the ratio of compression while maintaining volume of heat absorption. Again, please tell me if im way off. Of coarse air flow needs reduced indoors. Out door fan should be fine?
