#3: Check your hot water heater’s temperature.
When it comes to the temperature settings on your water heater, make sure it’s safe and efficient — 120 degrees is where you want it to be!

Make sure your refrigerator is set between 37 and 40 degrees F and the freezer is between 0 and 5 degrees F.
#5: Check your heating equipment.
Make sure your furnace or other heating equipment is working properly by having it regularly checked and serviced. And change your furnace filter often to keep it clean!
