Air conditioners aren't cutting it

I'd say you get could by with only switching out one unit. But I think you might be wrong about wire size being the same atleast on my 36k it called for #8 wire.

Each 10kW room has a 4 ton minisplit, ceiling mounted.

Infrared light heats up the surfaces it hits and those surfaces in turn radiate heat into the area. You commonly hear of people sizing DE HPS using the "California rule" that quantifies a 1kW DE HPS at 5000 - 5500 BTU/hr and non air cooled SE 1kW HPS at 4500. Many big commercial grows use a large number of HPS lights and if they sized their AC based solely on 3.4 BTU/hr per watt then they would be woefully short on cooling capacity.

Do your units have separate ratings for heating and cooling? My units are 2 tons, but upon inspection the air handlers say 22k cooling, 24k heating.
