Ok guys need some help picking out a new ac for my room. I went small and it facked me..lesson learned.

Here is what I have in the room that is about 12x9
6x 600's air cooled
4x CMH open fixture style
2 big air pumps
Dehumidifiyer
2 chillers 1/4 hp
Soleous ac that is just struggling
Co2 burner but cant use because of high heat.

I think that is about everything worth mentioning that creates heat in the room for the most part.

I need a AC unit that will work in the dead of a Michigan winter.

I am figuring I need about 30,000 btu to be on the safe side.

I have been looking into a mini split ductless a/c unit from Friederich this is the model I was thinking in the 30700 btu model.

I would really like to make the right choice this time and need some help. I have around 3k to spend on the unit and or 6k to spend if anyone can point me out another more efficient way of cooling.

Thank you farmers
