Four year old very high quality Friedrich 20,500 A/C, 9.2 EER 220 volts draws only 10.3 AMPS will cool and entire small house. We cooled the lower level of our cape with no problem, extremely light use was only used for company or very hot weather. We have converted to a Slimline ductless system. Offered at $500, new was over $1,500, pick up only unit is fairly heavy but fits a standard double hung window or can be through wall mounted. PM if interested!
