"We were in the market for a solar system from a company that was reliable and we could trust. After doing lots of research we asked Sunlux to be our solar provider. They were very honest with their prices (they were on one of the lowest) and their customer service has been excellent? Since we did not know a lot about solar systems, they educated us to be smart consumers and gave us options and choices that met our needs. We can truly say, we are very happy with Sunlux and would recommend them to others as well."

"First, we had a consultation with Jim, who was very thorough and honest about all the options available. The crew were punctual and very considerate, making sure everything was covered in plastic to keep things clean. There were A LOT OF rocks and debris in the attic (apparently the roof used to be flat concrete). So, it took them all day instead of half the day to finish the work. I feel so bad for the crew, and they were still so nice."

Energy Efficiency Auditing questions, answered by experts

There are several strategic ways to lower your home insurance premium. The primary one is to shop around and get quotes every few years to make sure you’re getting the best deal. Also, sometimes bundling your auto and homeowner’s insurance will get you a discount on both. Finally, try to keep your credit score up; many homeowner insurance companies use credit scores to generate quotes.

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.

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.

String lights require electricity, but not an excessive amount, especially when compared to other lighting fixtures. LED rope lights, for instance, consume around one watt per foot. Running six or seven light strings simultaneously should only cost you around $10 to $15 each month. You can save even more money by remembering to turn off your lights during daylight hours. 

Provide utility bills and clear access to all areas of the home, including the attic and basement.
