I agree. My Central Air conditioning/Heater was old and using alot of power. It was replaced with a bigger one, however an energy efficient unit. I save alot every month. It does not have to work as hard. Thanks, Royal...

Most utility companies will have some type of calculator that a homeowner can use to figure out how much energy certain appliances use. Most older appliances use quite a bit more than newer ones. Here are some tips that I tried and actually saw a decrease in my bill:

Turn all monitors off when not using them. This includes TV's. Unplug all transformers when not using them- such as your cell phone charger. Turn your water heater down to 120 degrees. Turn your freezer setting down one number. Put energy saver bulbs in all light fixtures that are on overnight. Install a digital programmable thermostat, and then program it. Blow in cellulose insualtion in your attic to  R-49.

I read all of these on my power companies site. It took us 1 month to implement them all and we have saved an avergage of $20/month for the last 6 months. Give it a try.

Those light bulbs are great.  Cost 3 times as much.  I bought them for my home.  Within 8 months 2 of them went out.  The packaging claims they are going to last for years.  Right.
