As the U.S. faces a massive heat wave, don’t make these 3 mistakes when you turn on your air conditioning

Residents across the country are bracing for a major heat wave this weekend. And depending on where you live, the rising temperatures could equate to rising home cooling costs.

****The National Weather Service has issued heat watches and warnings and heat advisories across much of the country, including the Plains states, the Midwest and parts of the East Coast. From Boston to New York to Chicago, the combination of heat and humidity is expected to send heat indices upwards of 100 degrees Fahrenheit on Saturday.

****Extreme heat kills more than 600 Americans a year on average, according to the Centers for Disease Control and Prevention — so you can hardly be blamed for cranking up the air-conditioning during this heat wave.
