size of air condtioner req'd

I live in an 850 sq ft apartment and would like install a split unit air conditioner. I have a southern exposure, lots of windows and glass sliding panels that allow lots of light and heat in. I have several quotes of $3,000.-$10,000. to install. Every quote tells me I need a different size of air con. Has anyone got any ideas of what size split air con unit I need? Thanks

unless you own the apartment or the LL agrees to you installing the AC, you do not want to deal with a split unit.

Use the link yuri posted to be sure. For 850 square foot a ton and a half should be more then enough unless you live where it's over 100 most of the summer or like the cooling set on 68.
