"I was considering 3 companies to do the work. They provided the best deal. The installation went very smoothly; finished in a day. Very happy with the process to that point. Had some problems with some logistics afterward. The papers weren't processed properly to iniitally run the solar panels (it took 2 months till we figured out the electric company hadn't 'turned on' the panels). There was also some problems with the paperwork for the tax rebates that slowed things down. I talked to the owner Mark, who was very sorry for the problems and offered a small refund, even though we don't really know what happened. He wanted to be sure I was a happy customer, which I am. I was impressed by his professionalism. However, I'm still not seeing the savings that I was told. I've had my house energy audited, installed Nest thermostats, and still not seeing a major decrease in my KWh usage. I can only assume that we are having a hotter season than last year; hoping to realize savings next year.

"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! ❤️❤️❤️"

"Summary: Hire them - period! This review has 2 parts: 1) Diagnosis of existing system by Phil, the owner and 2) Removal of old / existing system and installation of new system led by Danny, the lead installer of the FOUR! (4) men on our job. 1). DIAGNOSIS of "Old" System My wife and I bought a townhouse in Greenville and I knew (per the inspection) that the old system was "shot". Consulted seller's realtor for an HVAC Company recommendation as well as Angies List, where I saw the reviews for Energy Sharks. Submitted online contact form and had a call by the owner Phil within the hour. Set up the appointment THE NEXT DAY to inspect existing system. I was not able to be onsite but Phil checked it out and then spent time to explain the issues with the current system, and educated me in PLAIN ENGLISH why the system he recommended, along with the addition of an additional return to help supply the necessary airflow, was what would be needed to provide the level of comfort which we desired. Price was competitive and definitely less than Realtor's referral, who didn't even mention the return / airflow problem. Bottom line, Phil did his job and gave me a quote that I thought was fair (and thousands less than the other quote)... 2). REMOVAL of old system and INSTALLATION of new system. The crew of FOUR (4) MEN arrived at 7:15am and immediately got to work. They put in drop cloths everywhere they would be working and went about their work in a steady manner. A HUGE shout out to Danny, the lead installer. ASK FOR HIM on your job! He kept me constantly apprised of what was going on, where there were some holes in the ceiling that pre-existed, where the new return could be and should be, etc. Can't tell you how competent the entire team was. Each of the men did their part and they worked very efficiently. Less than 4 hours later, they were done. Got a quick tutorial and they were on their way. Summary: Prompt service, fair pricing and excellent communication means I am pleased to refer them - without reservation. Great job Energy Sharks! A+"

Energy Efficiency Auditing FAQs, answered by experts

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.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

Depending on the level of audit you choose, a home energy audit will at least include a walk-through of the home to determine visible inefficiencies, but may include testing and a highly detailed inspection and report laying out the home’s inefficiencies and providing recommendations to fix those issues. The audit may also include a review of utility bills and mechanical testing. Consult your home energy auditor about the types of services they provide before hiring.

The answer is a resounding yes, as dishwashers save significant water and energy compared to washing dishes by hand. The difference is so drastic in fact that those who use energy-efficient dishwashers can expect savings of over $450 per year. This is because dishwashers use less water, they wash at a higher temperature than a hand rinse, and you don’t need to rinse them after washing. New dishwashers use around 4 gallons per load, whereas washing by hand can use up to 2 gallons per minute.

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.
