Air conditioners can cost homeowners in the U.S. upwards of $11 billion annually, but if you’re not paying attention, your furnace could cost just as much as your summer air conditioning bills.

While there are a lot of useful tips to help you save money on your air conditioning and heating services, there are also some myths that you need to stop perpetuating if you want to save money this season. Here are a few of the most common myths you should be wary of this winter.

Crank it Up
Believe it or not, some people are still under the impression that setting the heat to an unreasonably high temperature will heat a space faster. While it will make your home incredibly hot, it won’t make it happen faster. Rather, it will burn more fuel more quickly and kick your heating bills through the roof.

The Fireplace Fallacy
While a fireplace is aesthetically pleasing and a status symbol to many, the truth is that it’s not a very efficient way to heat your home. After paying for firewood and then letting most of the hot air escape through your chimney, it’s not exactly the best way to save money while it’s snowing outside.

Programmable Thermostat Issues
While this is actually an effective way to save money during the winter, it’s only effective if you use it correctly. In its default mode, a thermostat will keep your home cooler at night and warmer during the day. However, if you set it to a higher temperature every morning, you might not save as much money as you think.

Leaving the House at a Constant Temperature
Contrary to popular belief, you shouldn’t leave your heat at a constant temperature all the time. It’s actually much more cost efficient for your home if you turn the heat down at night and keep it a little bit warmer during the day.

The key to saving money on your heating bills this winter is moderation. Heat your home in moderation and bundle up, then you won’t have any issues.
