## 5 Energy Myths Debunked

Managing your home's energy efficiency doesn't have to be challenging. In fact, it can be quite easy. To help, we're busting five common myths with practical tips.

| **MYTH:** Turing off your HVAC system saves energy. **FACT**: Re-cooling (or reheating) makes your system work harder and uses more energy. Instead, set your AC temperature 3 degrees higher and your heating temperature 3 degrees lower while you are away. Better yet, install a Smart Thermostat and let the efficiency settings happen automatically. |  ![T-stat.jpg](https://residential.savenow.cpsenergy.com/hs-fs/hubfs/T-stat.jpg?width=179&name=T-stat.jpg) |

| **MYTH**: Changing HVAC filters monthly helps your system run efficiently. **FACT**: Dirty filters make your system work longer and harder. While monthly changes may be sufficient during winter months, replacements in summer should occur every two weeks. |  ![537890825_filter.jpg](https://residential.savenow.cpsenergy.com/hs-fs/hubfs/537890825_filter.jpg?width=162&name=537890825_filter.jpg) |
| **MYTH**: Leaving the ceiling fans running will keep your room cool. **FACT**: Ceiling fans cool people, not rooms. Turn off fans in unoccupied rooms. |  ![Fan.jpg](https://residential.savenow.cpsenergy.com/hs-fs/hubfs/Fan.jpg?width=167&name=Fan.jpg) |
| **MYTH**: Turning off an appliance stops it from using energy. **FACT**: Most appliances draw energy even when turned off. Unplug them from the wall. |  ![537890825_coffeemaker.jpg](https://residential.savenow.cpsenergy.com/hs-fs/hubfs/537890825_coffeemaker.jpg?width=128&name=537890825_coffeemaker.jpg) |
| **MYTH**: Closing vents and registers saves energy. **FACT**: Closing vents and registers redirects airflow to other rooms and expends the same amount of energy. The added pressure from closing a vent could cause air leaks and unnecessary energy waste. Turning your thermostat down in winter and up in summer will save energy. |  ![483816916_Vent.jpg](https://residential.savenow.cpsenergy.com/hs-fs/hubfs/483816916_Vent.jpg?width=120&name=483816916_Vent.jpg) |
