How Can You Know the Best Temp to Set AC in the Summer?

What’s the best temp to set AC at? You need some air to get you through summer in Florida, but how do you keep cool without sending your energy bill skyrocketing? Here’s what you need to know about setting your thermostat.

How to Set Your Thermostat

According to the Department of Energy, the best temp to set AC in the summer is 78 degrees. That may seem a little high, but it’s generally enough to keep you comfortable while still saving energy. Start at 78, and if that’s too hot, you can always bring it down a bit. If you do lower the thermostat, do it one degree at a time until you find a temperature that makes you feel cool.

Never set it below 70 degrees, though. The evaporator coil’s temperature will drop too much too quickly, possibly causing it to freeze. Likewise, never run your AC if the outdoor temperature is below 60 degrees. That can also freeze the evaporator coil. If your house is too warm while it’s cool outdoors, try opening a window. You’ll get clean, fresh, cool air without having to pay for it.

How to Reduce Your Energy Bills

If you really want to save energy, try setting your thermostat even higher than 78 degrees. You might think it will be too warm and that that’s not the best temp to set AC, but there are a few energy-saving tricks you can try to make higher temperatures more comfortable, starting with ceiling fans. By running a ceiling fan, you can raise the thermostat a few degrees without reducing comfort. The windchill factor makes the air seem cooler than it is.

You can also try getting a whole-house dehumidifier. While the temperature can vary, the humidity in Florida stays high year-round. That high humidity inhibits sweat evaporation on the skin, which makes the air feel hotter than it is. A dehumidifier will help you feel cool and comfortable for a lot less energy.
