"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."

"Failed to show up on agreed upon work date due to overbooking. Bid vinyl for an aluminum replacement, then was unresponsive about bidding aluminum. When we decided to go elsewhere, six months later they sent us an invoice for an additional, arbitrary $3k for work not performed. We disputed the invoice and never heard back until we got another invoice another seven months later seeking double the original amount including monthly interest and an ‘overhead & profit’ fee."

Energy Efficiency Auditing questions, answered by experts

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. 

You can increase your home’s load factor by replacing fuse boxes with a circuit breaker, hiring a licensed electrician to upgrade your electrical panel, upgrading wiring, or installing subpanels. An electrical inspection by an expert can help determine the state of your current electrical systems and how they can be improved.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Thankfully, LED lights use less electricity than incandescent lights, meaning you won’t spend as much on utility bills by using these light strips. Each 5-meter LED light strip will cost about $3 per year on your energy bill.

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