I bought  this ac about a year ago and I  have always taken excellent care of it. I'm  a single mom and work 60 + hours in the Texas heat. Now I'm a single mom who works all day in the texas heat and now I sleep in it, as well. It just displays CH 26 error. I wor hard  for my money, when I buy something  I expect 
it to last.. 
 If your looking for  something  short term, go for  it.
