Have you finally had enough of the Boston heat this ovenlike summer? Here‘s a great list of places in Boston to cool off indoors with free AC. But if you’ve already read all the books in the Boston Public Library and spent all of your money at the Prudential Center in an attempt to escape the heat, you may be ready to buy your own AC unit. Forking over approximately $150 for a brand new AC unit, and cooling off in your own home, is definitely the more economic choice if you’ve been holed up in the Prudential or at Copley Place. So here’s a list of the cheapest AC units (new ones at the top and used at the bottom) that I found while scouring the internet for my own personal air conditioner:
