"Energy Smith is a top rate company: Joe took time to review my concerns, put together a detailed plan and estimate. The crew arrived as scheduled very courteous and went to work sealing leaks preparing for insulation. Installed copper foil where needed, cleaned up attic space. Looks great, already feel difference in room temperature. Great job!! Thanks much."

"Rep. checked entire system. He found several wires not connected properly and fixed this. He also made recommendations regarding the attachment of the panels to the rood that would provide more stability and leakproofing. The representative appeared to know what he was doing - much better than others, including the representative who was engaged by the roofer (who replaced our rood due to hail damage) to disconnect/connect the panels."

"It was thrilling. Without the Corley guys’ diagnostic and electrical expertise, the house would probably have burned down. Seriously. This was a bona fide emergency. It was puzzling and difficult for them, and stressful for us — before it was over, I had evacuated the house — and we were making weak jokes about poltergeists and exorcists… but apparently a squirrel had chewed up the Duke Energy line, sending thousands of units of raw electrical power into the house! ????? Afterwards, I needed a vacation somewhere — anywhere — quiet… but thanks to Corley, we have a house, new wires, and are (relatively) sane. Thanks again, Corley crew! ❤️❤️❤️"

Energy Efficiency Auditing questions, answered by experts

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

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.

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.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Dehumidifiers typically use 300 to 700 watts of electricity per hour, whereas portable dehumidifiers use about 40 watts per hour. The exact amount of electricity your dehumidifier will generate depends on its capacity and energy efficiency. Generally, higher-capacity dehumidifiers generate more electricity than lower-capacity units, but they also usually have better energy efficiency over the long run.
