It's been in the high 90's to low 100's the past week driving home on I-15. The AC had no problems keeping up in ECO mode. Very comfortable!

The coldest AC I've had is my F-150. That thing holds 4 lbs of freon and blows 34F air according to the thermometer in the vent. On humid days it blows ice flakes out the vents. The TCH takes slightly longer to get cold, but on max it definitely blows nice and cold.
