How Much Does a Home Energy Audit Cost?

Whether you are interested in saving money on your electricity bills each month or you simply want to do your part to help create a greener planet, having a professional home energy audit done can be a smart move for any homeowner. This audit involves having an expert test everything from the heating and cooling systems in place to checking on insulation, appliances and air leakage. Tests can be quick and involve standard practices, or they can be more in-depth and include upgrades like infrared scans to check for thermal changes. Using this guide can be a handy way to know what to expect when it comes to the cost of a home energy audit.

Average Cost of a Home Energy Audit

As mentioned briefly above, a home energy audit can vary depending on how extensive you want the process to be. Generally, the process takes between two and three hours to complete, and you will get results within the week of the audit. While it is impossible to pin down an exact number, the typical cost of a home energy audit runs between $286 and $342, with the higher end being reserved for particularly large homes as well as older homes that are more likely to need additional attention due to energy inefficiency.

Potential Ways to Reduce Total Audit Costs

One of the big ways to reduce the cost of a home energy audit is to speak with your electricity provider about potential rebates. Many companies offer rebates to their customers who have audits done as a way of responsibly reducing resources and being more informed consumers. However, these rebates will rarely cover the entire cost, and most range from $50 to $100 off the total project.

Costs of Implementing Energy-Efficient Changes

For most homeowners, the objective of a home energy audit is to find out how upgrades or changes can improve energy efficiency and save money down the road. However, these upgrades and implementations that can save energy will also cost money upfront. These renovations can range from upgrading your windows to completely replacing the home's HVAC system, and the prices can vary substantially.

Having a home energy audit done is a wise decision for homeowners who want to ensure that they aren't wasting money on heating, cooling, water or energy costs over time.
