Gently used portable air conditioning unit, with easy window installation. 9000 BTU, great for apartments and small homes, especially for renters who do not want to leave marks on windows or doors. The blue strips are just tape from the packaging, and I should still have the instruction manual if interested. I'd just need to find it. Pickup in Redwood City.
