How well is my home insulated?

If you can see your ceiling joists, you need to increase the amount of insulation in your attic. Attic insulation should have at least an R-30 rating.


How tight are my windows?

Single pane windows should be replaced with double pane, Low E windows with a U value between .30 and .39.


How efficient is my central air conditioning unit?

Units that are 10-15 years old aren’t very energy efficient. In the cooling mode, energy efficiency is based on the unit’s SEER or EER. Anything greater than 10 is good, 12 is better. In the heating mode, look for the HSPF for heat pumps or COPS for geothermal systems. The higher the number, the more you will save.

Phantom Load

Many electronics continue to use energy even after they are turned off. It’s what we call phantom load, and it accounts for approximately 43 billion kilowatt hours of wasted electricity.
