How high is high, 8, 10 ,20, 30, 50???????????
and if it is high what indication can you get from the evap that it is performing correctly,
Some rooms i've worked on can take hrs to pull down, there must be some indication via evap td or air dt that indicates correct operation.
Mistakenly so i've always gone by evap superheat, and now i'm trying to correct myself and an understanding of why is always helpful.

Thanks CB
