Do you own the house? Maybe consider a split ac unit. I installed one in a guest room I built on the back of my garage. They make DIY versions now that come with freon installed so they are basically plug and play after running electrical to the main panel. Very easy to install, took maybe 2 hours. I paid 590 for this one about a year and half ago, looks like its no longer available but there are probably simliar models available.
