Energy Efficiency Auditing questions, answered by experts

Yes, Tesla Powerwalls are worth the upfront costs, as you can recoup your investment within six to eight years. Plus, they provide peace of mind that you'll have power during a power outage, and, depending on the system you install, you can become energy-independent. While they may be more expensive than other solar power systems, they offer higher battery capacity and lifespan.

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.

Typically, a local home energy auditor is responsible for performing energy audits. A home energy auditor will conduct one of three energy audits designed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) to determine the energy efficiency of your home. The auditor often provides analysis that can help guide changes and improvements to your home for better energy efficiency, giving recommendations as necessary.

Modern windows provide enhanced UV protection, improved heat retention, and cooling efficiency, contributing to overall household energy savings.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
