Summary: using for small room. works good. likely would cool large room. good & powerful. cycles on & off to keep temperature accurate. pretty quiet. not like window unit. no adjustment on airflow direction. short distance needed to exaust window. (3') definitely exhaust needed. otherwise hot moist air recirculates in room defeating the purpose. reduces humidity too.
Summary: In our RV, some sites we park in have little to no shade. Bought this unit to ease the load on our rooftop unit. Before adding this unit, mid afternoon temp would often reach 80 deg. with roof top units running full blast. After adding this unit, we can maintain a constant 73 or lower. No problems with this unit in any way.
Summary: We don't normally see temps in the upper 90s in Upstate NY, but we did this week. [...] Our master bedroom is about 300 SF on the second floor, which gets full sun for several hours in the morning. We have 8 foot patio doors to a small deck and two 12"x36" "eyebrow" hopper windows, so a standard window AC unit was not an option. The Delonghi PAC A120E portable AC is the perfect solution for our room.
Pros: Cools the Whole Room, Easy To Install, Easy Window Installation, Handles odd shaped window
