I have 2 a/c unit devices avaliable. 1 is a Frigidaire 12,000 BTU window device. Functions very well. Demensions are 19"W X 21.5"D X 14.5"H. The other system is a Soleusair portable 4 period system. It has 4 various modes to choose from: cooling, dehumidify, fan, and heating. $ 250 or make a sensible offer for each unit. Both of these systems have just been utilized in a smoke complimentary environment. If no response, leave a message and I will certainly return to you as quickly as I can!
