Hot Enough? Here Are The Best Air Conditioners Under $300

If you’re on a tight budget, sweating out the summer with no air conditioning may sound like a good way to save money. But a sizzling June brought record highs to more than 40 U.S. locales, and a heat wave is gripping much of the nation. So if you feel your willpower starting to melt, here’s how to find an air conditioner for less.

Let’s start with the basics. The first thing to note in an air conditioner is its cooling capacity, which is measured in BTU, or British thermal units. The size of your space determines how much cooling capacity you need. Budget air conditioners range from 5,000 BTU, which can handle about 150 square feet, to 12,000 BTU, enough to cover about 550 square feet. Naturally, air conditioners with higher capacities have higher price tags. But beware of buying less (or more) than you need; you’ll pay the price in performance and efficiency. This government chart can help you determine the right size for you.
