"I was thrilled with the work Enlighten Energy Solutions performed on my solar panel system. Ethan worked with me and listened attentively while I explained my issues with the system. He was able to diagnose the problem with the system, complete repairs, and verify the whole system was operating properly. He was extremely courteous and professional and I will absolutely call on them again."

"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.

Energy Efficiency Auditing FAQs, answered by experts

Energy-efficient windows are judged on their performance according to a few different factors, including heat transfer, air leakage, light transference, and condensation resistance. If you're unsure whether a window is energy-efficient, look for an ENERGY STAR® label from the U.S. Environmental Protection Agency (EPA). If various products, including windows, meet energy-efficiency standards set by the federal government, the EPA issues this label to help consumers identify energy-efficient products.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

Yes, including optimizing settings and suggesting upgrades if needed.

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.

A whole-house humidifier can positively impact energy consumption by improving heating efficiency. During colder months, humidified air feels warmer, which allows you to lower your thermostat without sacrificing comfort. This adjustment can lead to significant energy savings as your heating system works more efficiently. However, it's important to use the humidifier judiciously, as excessive humidity could potentially strain your cooling system in warmer months.
