Turn off air conditioning breaker (Change 103)

We actually made this change back in the late fall, but I forgot all about it until yesterday. (I was down in the basement putting stuff away in my chest freezer, noticed the breaker was off, and said "Aha!  I forgot to blog about this one!)

You may not be aware, but when your air conditioner is "off", it actually draws energy from the power grid, like any other item plugged into your home's electrical system.  According to a friend of mine, who is a heating/air conditioning technician, the phantom power is used to cycle a small heater in the air conditioner unit, which prevents the refrigerant from solidifying, so you can use your air conditioner as soon as you turn it on.  Since we don't use the air conditioner in the winter, I don't need to worry about the refrigerant not being ready to work right away.  He said that I could safely turn off the breaker to the unit, without harming it, and reducing any phantom power draw it might have.  I just need to remember to turn the breaker back on in the spring.

  2. Too bad! I can't say for sure it has helped reduce our energy footprint, but every little bit counts.

  3. Your eco-friendly lifestyle is inspiring. At home, we cut down on energy consumption by maximizing the use of natural light. We also reduced the use of non-biodegradable products like plastic packaging.

  5. To save on energy expenses, unplugging appliances that are not in use makes perfect sense. In the same light, turning off the air conditioning breaker ensures that electricity waste is prevented.
