I bought one of these about 2 years ago and it was great still works awesome. it was a great buy i havnt hd any problems with it. It still gets cold and puts out alot of air. One thing i have learned is to keep the fans clean as well as the condinser. if the fans get alot of build up on them they will not push as much air and if the condenser gets plugged it could over heat. That stuff is all part of maitnence that u have to do on all acs No problem with this unit every year for summer i turn it on and it works again ive only cleaned mine once i just take it to the car wash and power wash it the best way to do it. U don hve to worry about hurting anything either it a tuff unit. Its the best place to be when its 95 out i would recomend this unit to everybody. But my dad bought the same one because i told him it was great and he has already had his worked on i think the freeon pump went out could of been something to d with manufacturning.
