Utility Audit Defined: A Simple 3-Step Process! 
Here is the definition of a 3-step utility audit:
1. Utility bill audit of all common-area utilities to uncover past and present utility overcharges.
2. Onsite inspection of your property: this is where most utility bill errors are found!!!
3. Obtain refunds for prior overcharges and identification of less expensive utility rates to reduce future utility expenses.
If no utility overcharges or less expensive utility rates are found, there is no charge for the utility audit!
