And they only cool about 20% lower than the outside air temp. So pretty much useless when the temperature hits 110 or more.



I actually turned on my AC last night, but after about 2 hours it was hotter than when I turned it on. So it looks like I will be calling an AC repairman soon. Thank God for the swamp.
