SPT (Sunpentown International) is a great new company (founded 1993) in California which specializes in small appliances; I purchased one of their air conditioners, the SPT 10,000 BTU one. I was a little hesistant as I usually look for brand names (Frigidaire, Carrier, etc) when it comes to air conditioners but having read some positive reviews on their smaller size conditioners (5,000 and 8,000), no reviews for the 10,000 and 12,000, I decided to give this company a try. Well upon receipt, I was impressed with the build quality and packaging. Now I live in Chicago and this past Saturday, May 26, 2012 was a record 97 degrees in the city, got the air conditioner on Friday, put it in the window on Saturday morning, turned it on 66 degrees on the low cool setting and it cooled down my living and dining room area (roughly 600 square feet)with 10 minutes, outstanding air conditioner thus far!
