Thinking about becoming a home energy auditor?

2. Get an Energy Audit
Hire a local energy auditor and watch first hand what they do, both from a technical and a professional standpoint. We recommend doing some research first, like watching our Building Analyst Field Training Video: How to Perform a Home Energy Audit, so that you aren't seeing the tests and the processes for the first time. This way, you can concentrate on more of the nuances of how the energy auditor communicates what they are seeing and doing.

Are you going to be doing just audits, or is your company going to be performing some or all of the work yourself?
Answering these questions will help you determine how much to charge for the audit, and how to message your services. Most markets have 2 or 3 successful energy audit only firms - the rest of the energy auditors also are insulation installers, HVAC firms, home inspectors, remodelers, etc. If you are currently in the installation business, learning how to do energy audits shows you know how to diagnose and solve problems, not just install products.
Here's an excellent article on how an HVAC company that got into the energy auditing/home performance contracting business.
6. Become the Expert
Once you become trained and certified, and have all the equipment and infrastructure in place, practice! Perform audits for all of your family and friends. Treat them like real customers, and solicit their feedback on how you present yourself and educate them.
Once you have fine tuned your audit, messaging, and customer report, hit the pavement! Network with local environmental groups, give presentations, and give demonstrations to groups.
