Though just days old, Summer 2012 is off to a hot start in many parts of the country, and that means one thing for millions of sweltering people: air conditioning. And while we may take air conditioning for granted, it's generally an expensive luxury. Americans spend more than $22 billion a year on electricity to cool their homes with air conditioning — and use a whopping 183 billion kilowatt-hours, according to recent statistics from the U.S. Department of Energy. That accounts for at least 15% of all energy used in some homes, and in warmer climates can represent up to 70% of a summer electric bill.
If you're shopping for a new air conditioner, you'll notice quite a few different sizes and models. But one thing's for sure: Savings are always chill. Here's a quick primer to staying cool and keeping your wallet from overheating when picking out an A/C unit.
