Ok. Here's the story. My bedroom faces southwest and has three large windows. In the hottest part of the day the sun beats down on those windows and makes it really hot in the room. There used to be a large cottonwood tree in my front yard that shaded the front of the house in the afternoon and it was never an issue. Unfortunately, I had to take that tree down several years ago. I have central air and the rest of the house stays comfortable. It's just my bedroom that seems to be ten degrees hotter than the rest of the house.
Not looking to to spend a ton of money right now. Looking for a quick, easy fix. Don't even care too much if it's a little ghetto.
I'm leaning towards blocking or partially blocking the windows with styrofoam sheets like they use for insulating houses or maybe installing a small AC unit in one of the windows. Thought about tinting the windows but they really need to be replaced soon anyways so I'd rather not waste the time or money doing that.
What are some of my other options?
