Energy Audit Costs

Professionals & Services Cost Guides      Energy Efficiency      Energy Audit Costs

How much energy are you using each month in your household? Do you feel that there are places where you are wasting energy and where you could cut back to reduce your bill? Are you looking to find a way to make your home truly energy efficient to do your part to help the environment? Having an energy audit done by a professional can help to make it easier to understand where your home might be having problems.

The energy auditor will check a wide range of different features in your home, such as the insulation, the windows, and doors for air leakage, appliances, water leaks, and more. Often, the auditor will want to look at your energy bills, as this can help them to determine whether you are paying too much each month based on the size of your home. They will generally be able to go through a home in a couple of hours and conduct the audit. It will generally take several days before they provide you with the report. Once you have the report and know where the problems lie, you can then start to make the changes you need.

Other considerations and costs

  • Larger homes will have a higher cost for an energy audit because the auditor will have more to examine and test.
  • Older homes will often exhibit far more problems with energy efficiency than new homes.
  • Although the fixes to issues found during the audit will cost money to fix, they can help save money over the long haul.
  • Many auditors will charge per square foot, but there are also those that will charge an hourly cost instead.

DIY considerations

  • Because an energy audit requires a high level of experience and expertise, as well as tools and equipment that are not readily available, you will need to hire a professional. However, you can look at your energy bill and compare it with the average of what homes in the area are paying to get an estimate of whether you are paying too much for your energy.
