How Much Does A Home Energy Audit Cost?

The Department of Energy recommends that you conduct an energy audit before making any energy efficient upgrades to your home. An energy audit, also known as an energy assessment, helps you learn more about your energy consumption at home. The results of an audit will reveal the amount of energy you use, how you are wasting energy, and what steps you can take to save energy. 

In other words, an audit can help you identify opportunities to reduce your energy consumption and lower your monthly utility bills. But how much does a home energy audit cost? Here’s what you should know:

How Much Does A Home Energy Audit Cost Per Square Foot?

Some professional energy auditors price their services by the square foot. This is because the bigger the house is, the more work that an auditor will need to perform to complete their assessment. 

The average cost of a home energy audit ranges from $0.12 to $0.35 per square foot. Based on these numbers, here’s how much it would cost to perform an energy audit on some of the most common home sizes:

  • 1,200 square foot home: $144-$420
  • 1,500 square foot home: $180-$525
  • 2,000 square foot home: $240-$700
  • 2,600 square foot home: $312-$910

How Much Does A Home Energy Audit Cost By Type?

The price of a home energy assessment can also vary by the type of audit performed. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) recognizes three different types of home energy audits.

The first is an ASHRAE level 1 assessment, which is the most basic type of audit. A level 1 assessment is also referred to as a walk-through because the auditor simply walks through the space to visually evaluate how it uses energy. The auditor may also discuss energy concerns with the homeowner and review the homeowner’s utility bills as part of a level 1 assessment. The average cost of a level 1 energy audit is between $0.08 and $0.12 per square foot

The next type is the ASHRAE level 2 assessment, which is more extensive than a level 1 assessment. In addition to a visual inspection, a level 2 assessment also includes an evaluation of how individual appliances and other equipment use energy. The auditor will also prepare a list of energy efficient upgrades that the homeowner should make and include the estimated cost of making these upgrades. A level 2 assessment can cost between $0.12 to $0.35 per square foot.

The final type is the ASHRAE level 3 assessment. This level includes everything from a level 1 and level 2 assessment in addition to comprehensive analyses, surveys, and an evaluation of the heating and cooling system’s energy usage. Because it is so complex, this type of energy assessment is usually performed on commercial buildings. But if you would like a level 3 assessment for your home, it will cost between $0.36 to $0.50 per square foot.

If you plan on hiring a professional to conduct an audit, make sure you understand which level of assessment the auditor is performing. This way, you can estimate the cost of your audit in advance.
