"I received the company's info through Duke Energy. The owner came out to the house within a couple of days to complete an assessment and provide a quote. Once I had some other work completed, I called back to schedule the appointment for removal and install, and they came out within a couple days, removed all the old insulation and blew in the new insulation. They were done, cleaned up and gone, before I ended my workday. Excellent job and crew! When I complete add-ons in the future, they will be the company to handle the insulation."

"We met with 3 different companies to advise on getting solar panels. The first 2 companies basically just told us what size system we could get based on state and federal tax rebate levels. Heard an advertisement for Sunpro on radio and decided to call them; turned out to be a good decision. Kara with Sunpro was extremely informative and had a nice package put together for us to review. She even researched our home and had an idea of how much production we could expect with the recommended solar panels. Even after selecting Sunpro, I called Kara with questions about things I'd heard from others or something I forgot to ask. I never felt like I was a burden and she always returned my calls if I had to leave a message. The complete team with Sunoro were professional and eager to help. Satisfied with new solar system and looking forward to enjoying savings on electric bills.

"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! ❤️❤️❤️"

"Arrived on time, Ryan and Danny took the time to understand what needed to be done, verified in the oven manual for specs for hookup, and ran the replacement circuit. Outlets took a little more time due to house wiring (not their fault) but never felt rushed. Great job.

"I got proposals from 3 other contractors, all had very similar higher cost approaches.  One of these contractors has been maintaining my system for years.  Energy Sharks is different, 
Phil is special, he has a technical skill and product knowledge to specify the right equipment to meet our needs that exceeded our expectations.  He is a master at understanding where to spend our dollars to get the most benefit.  Costly features that sound good but have little payback are vetted by Phil.  He knows.  He even thoughtfully considered how to maximize our Energy rebates and tax credits by selecting the right eligible products ($950). 
The workmanship of the installation was Excellent.  Danny arrived on time and completed in the time period (less than 1 day) during the one of the coldest days of the year.  The system works great and I could not be more pleased. 
Thanks for a Great Job!

Energy Efficiency Auditing FAQs, answered by experts

Yes, energy-efficient options such as LEDs and solar-powered lights are available. These alternatives consume less electricity, resulting in lower utility costs. They are also more environmentally friendly due to their reduced carbon footprint and longer lifespan.

Services by electricians can quickly get expensive, but there are a few ways you can save money in the process:

  • Bundle multiple jobs done at the same time to save on trip fees or flat fees for individual projects.

  • Get at least three quotes for service to find the best deal.

  • Buy fixtures, switches, outlets, and other materials beforehand to avoid product markup.

  • If you feel comfortable with it, have an apprentice or journeyman complete the work under the supervision of a master electrician. These electricians in training tend to charge less per project.

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.

Yes, energy-efficient windows really can make a difference. As long as energy-efficient windows are properly installed and maintained, they can reduce your energy bill and offer significant savings.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.
