Joe Holmes with Decatur Utilities says if you're not falling for the typical myths, you have a chance to save.
Myth number 1? "One of the things that people always say is ‘I will shut off a few rooms to my house,’ said Holmes.” The truth is, your HVAC unit is designed to heat and cool that entire house, and you're actually filling that duct work with the same amount of warm air and actually will throw the system into imbalance which can make it work even harder, which will cost you more money."
Which leads to myth number 2: Turning off your HVAC unit when you leave. "We recommend that you turn the unit down, but not completely off, if you're going to be gone for an extended period of time," said Holmes. The magic number to set it on while you're away? 55 degrees.
Holmes says once you return you can bump it back up to your desired temperature, but not a degree more. "The unit is going to work to get it to the point that you set it, and if you call it to go higher you can set off that axillary heat and that can become expensive," said Holmes.
For every degree below 68, you are saving two to three percent on your bill. And if you think a space heater will help save, think again. It's actually more expensive. But one thing that he says works every time is weatherproofing your home. "Especially around windows and doorways you'll see cracks, and if you can see sunlight, It's time to fill that up with caulk or weather stripping," said Holmes.
