"We just had our attic and crawl space insulated and a moisture barrier put in. The crew showed up on time and every one of them was polite and professional. We could tell they had a lot of experience working together because they were super organized. While the boss, Dave, walked us through the process in detail, making sure we understood the job, behind him the crew set up quickly and efficiently, treating our home with respect. They were finished right on time, too, and left our house looking as if they had never been there. Before they left, Dave showed us their work and explained how these improvements would make our home more energy efficient. Every crew member made sure to say goodbye to us. They were amazing people! We highly recommend Building Energy Experts."

"I had Illinois Valley Insulation at my house to blow in insulation in my garage attic. I was told by the owner Scott Bickett that I needed an R30 value which means I would need about 8 1/4” of insulation blown in. He was paid in cash($1500 paid in full but only did half the work), and a couple of days later I went up there and measured and only have about 4 1/2 inches so he only did about half the work and charged full price. And when I confronted him, he told me there’s8 to 10 inches up there which is a lie and I’ve given him every opportunity to call come by Measure and prove to me that is there, but he has failed to do so because he is just proving my point that he is in the wrong. And now he still will not provide me with a receipt so he’s trying to keep the cash and hide it like he didn’t do the Work very unprofessional."

Energy Efficiency Auditing questions, answered by experts

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

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

If you want a new boiler that’s going to help lower your fuel bills, you should buy one that has a high energy-efficiency rating. For example, a boiler that is rated “A” uses at least 90% of the energy created by the boiler. And in order to enjoy the best performance, it’s important to have it installed properly by a highly-rated tech.

Yes, including optimizing settings and suggesting upgrades if needed.

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably.
