"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

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

Energy-efficient windows cost more than other window types, but they can help you save on your monthly energy bills, get you some breaks on your taxes, and even increase the value of your home. According to Michael S. Regan, Administrator of the U.S. Environmental Protection Agency, when people invest in green upgrades like energy-efficient windows, they save energy, money, and more.

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

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.

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.
