Ordered to replace a DeLonge portable ac on wheels. Purchased the GE 10000 btus. Room 390sft. 26X15. Arrived 1 day early. Had for 2 days prior to installing. Husband read instructions and we watched the GE video on how to install.  Not difficult. I have not cut thr foam insulation for the right sided panel yet. Only installed yesterday. We plan to place some foam order the unit we can see a little light under there.  I have a G E fridge that is probably close to 30 years old and bought a GE freezer from wayfair a couple of weeks ago. Very pleased. AC arrived well packed. no dents, dings or scratches. Remember do not remove drain plug the water turns into a mist and is blown over the coils to help the efficiency and do not plug in till after it has been level for 24 hrs, for coolant to level out. I have central air but really like bedroom cold at night. Do  not need to keep the other 2000sft that cold at night. This is perfect.
