"Everyone should have an energy audit done. Merv was excellent he explained everything and educated us on what we needed to have done, never once did I feel pressured. Merv came out in June and had a estimate with his recommendations back to us in a few days, sadly due to health issues we could not immediately address the issues."

"Bob the owner helped me through the whole process from having the audit done on my home and did the insulation work as well. His crew was also polite and hard working, they got the job done when they said they would and I’m so pleased with the results ! My home is the same temperature on every level and my energy bill is lower then it’s ever been. Thank you Bob and your team I will definitely be referring you to my friends and family."

Energy Efficiency Auditing FAQs, answered by experts

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

No, it isn’t necessary to have energy-efficient windows. However, if you care about your energy bill and making your windows more energy efficient, fixing any heat, UV, or air transfer issues is an excellent way to lower your bills and keep your house cooler in the summer and warmer in the winter.

Audits typically take 2-4 hours, depending on the property size and energy systems.

To find a reputable home energy auditor, start by researching local companies that offer the service and check their reviews, methods, and certifications. The most reputable professionals are often Home Energy Professional (HEP)-certified by the Building Performance Institute (BPI). You can also consult the Department of Energy’s certified list of energy auditors or use a state licensing tool to review local guidelines and ensure you are hiring a certified professional for your area.

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems.
