I decided that the time has come to put an a/c in my kitchen so I can cook comfortably. My kitchen is a 15x8. I cook there and we eat dinner there. There is no door to close the room to keep the air in but I do plan on buying a tension rod and curtain to at least try to close of the room. My kitchen is off my foyer in the front of the apartment. What size a/c do you recommend I buy? Also, what tools will my brother in law need to install it, and lastly where do find the most reasonable a/c, Buzz Drimmers Walmart or Amazon?
