Home energy audits help you see the big picture of your home’s energy use. This includes energy use, energy loss, comfort, and safety. For these reasons, conducting an energy audit can be an important step to take before creating your energy plan and taking action on your home energy transition.
What does the audit consist of?
Home energy audits generally last 2-3 hours. During the energy audit, the auditor conducts diagnostic testing (including thermal imagers and fans) to assess each room of the house. Two common tests are the blower door test and thermographic inspection. The auditor also asks you questions about your energy bills and energy use. For example, they will be interested in how many people are at home during the day, what your average thermostat setting is, and if there are any unused rooms, etc.
What do I get from the audit?
After the audit, you receive a detailed report. This includes all the sources of energy loss in your home (air leaks, insulation sinks), options for prioritization of tasks, and recommendations for improvements. Auditors will also provide financing information about those next steps.
How much do energy audits cost?
The average energy audit costs $425. However, you may qualify for a free energy audit if you qualify for CVOEO’s weatherization assistance program.
Can I do it myself?
The most thorough way to understand your home’s energy efficiency is by hiring a professional to conduct an audit. If you decide not to hire a professional or want to get a feel for your home’s energy use and loss yourself first, there are several easy ways to conduct a mini-audit. Read this guide on DIY home energy assessments from the Department of Energy.

How do I choose an auditor?
Before moving forward with an energy audit, it is important to ask the auditor some essential questions. Below are some examples of critical questions to ask:
- What certifications do you have? (Depending on what incentives you qualify for, your auditor may need to be certified by one of several organizations.)
- Will you conduct carbon monoxide and explosive gas testing on my water heater, fireplace, and furnace?
- Will you conduct a blower door test?
- How will you inspect the home’s insulation?
- Will you use thermal imaging to analyze my home’s air leakage?
- Will you review copies of my energy bills?
- Will the audit include additional testing after improvements have been made?
- After the audit, can we discuss your recommended improvements?

How do I prepare for the audit?
Before the auditor arrives, make sure that they have access to all of the rooms in your house, including the attic and crawl space. It can also be helpful to create a list of questions and priorities so that the auditor can best target your needs.
