"Strongly recommend getting an energy audit completed on your home, especially when it's complimentary, thank you, Paul! There were quite a few items that needed attention in our home. The technicians Justin and Fernando were solid. They arrived on time, did a great job, were polite, and were very clean. They took before and after pictures, which shows how much I needed the work done. We went with the insulation to ensure it was at least 18 inches, the duct sealing of the junction boxes and HVAC unit, and we had to reroute the bathroom vent. We even did the optional UV-C light, which makes us feel much safer and takes a load off, especially in this current environment of being conscious of germs and all. Great technicians, great company, and solid work. Highly recommend Justin and Fernando :) The email and text reminder game is on point."

Everyone I dealt with from SRE (from the salesperson to the technician) was so nice and professional. I have already told all my friends and neighbors about this company...outstanding customer service!!!"

"My experience with Energy Attic USA went really well. They were very good price wise. They did a good job and they’re the only company that I find that would do a reading and barrier that actually use a metallic foil reading barrier that they would put in instead of spray. That’s what I wanted. It’s supposed to be much better. It’s all under insulation."

"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."

Energy Efficiency Auditing FAQs, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

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.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

Audits include inspecting insulation, HVAC systems, windows, and appliances to identify energy inefficiencies.

The number one culprit of high energy bills is older appliances, especially fridges and freezers that are left on all the time. These two appliances tend to last a long time, which is good, but it also means that newer models are usually significantly more energy-efficient due to upgraded technology. The second most common reason for a high bill is heating and air conditioning.
