A home energy audit is a way for home owners to effectively measure their annual energy usage and expenditures in their homes. The audit can identify areas of your home which use the most energy as well as check the efficiency of your home's heating and cooling system.

Check with your local utility company to see if they provide this audit service and at what cost if any. You can also call an independent energy auditor for a comprehensive analysis. If your home is not using energy at its optimal effectiveness, they may recommend inexpensive ways to cut down on energy costs, as well as home improvement products that will help you save.
