I'm sold, I don't think it's a gimmick. I just I wish I had stats to take to my better half for backup They always help :lol:

We have two 3.5 ton A/C units for a house of 2800 sq. ft. I don't think one 5-ton HVAC is enough to cool that size of a house.

Either you have much less insulation than I do, have the tempature set noticably lower than I do, or your ambient temp is much higher than mine.

Well, it is the Sonoran desert in Phoenix, so it is pretty hot. I'm no HVAC guy, but my old house in the Phoenix suburbs was 1941 sq ft, 2-story, and after a load calculation a 4-ton unit was recommended.
Current house is 2-story and per the HVAC guys anyway, for this climate and square footage, they said per their load calculations, this is what they recommend. I have heard that in Phoenix a 5-ton can cool up to 2500 sq ft, but anything larger, more than 1 unit is needed.
However, my knowledge in this area is very limited and based only on what HVAC techs here have told me.
