My experience was excellent. I have used Illinois Energy before and the results were just as good as the other 2 times I used them in the past
"Overall working with Dan was a great experience. I had hired Dan to perform an energy audit. I had the attic insulated to R-38, but one room was still rather chilly. I needed the audit to pinpoint the issue. Now I know each area of infiltration and how to address each. Finally, Dan spotted an issue with my hot water heater. I'm especially grateful of this last point. Dan obviously knows his stuff and has the experience to back it up. I highly recommend him for energy audits."

"Greg, the owner, came out on two occasions to discuss the crawl space and drain tile. He is extremely knowledgeable and experienced in the crawl space industry. We had a few options and he told me about the new spray product he was using. It is this unique seamless liner that is sprayed on after preparing and insulating the area. His crew was very professional and easy to talk to. We had some scheduling conflicts that were easy to work around and get the job done when we needed it to be finished. The difference we noticed in the smell in our basement, the effect the insulation and seamless lining had on the air conditioning in our family room (which is above the crawl space) was immediate. We feel cooler air coming through the duct work since it isn't losing energy traveling through a non insulated space anymore and they basement smells and feels normal since the dirt and concrete is now completely covered by the new liner. That new product is great. Greg's company also did drain tile work in our basement. It was a different crew than the group who did the crawl space, but they were equally as professional and easy to work with. Rather than break up the job into 3-4 days they stayed late the first day to get everything ready and prepared so they could complete the job quicker. The job was done the next day. The price was very fair and the crew was extremely clean throughout thew whole process. We now have a water tight, well insulated basement and we couldn't be happier with the results. I have told several friends about the experience and would recommend them anytime. From Greg down to each of his crew members they really know how to do a good job and work with the customer."
"The work performed on the crack in the foundation of my house was done in a timely manner and the area around the house was left in good condition. I have had no further water problems. As for the insulation. I noticed immediately that the temperature of the coldest bedroom improved after the addition of the insulation. The set-up work area for the insulation was thoroughly clean-up when they were finished. This project took less time than I thought it would. I recommend using "Stop Wasting Energy At Home" for any work needed. "

"An energy audit revealed terrible problems with our home's insulation, and we decided to start with these issues before moving on to other, smaller, projects related to energy conservation. USA Insulation insisted that we would see a change in our home the very day they put in insulation, and I will have to agree that we did see improvements. I returned home to find 2" diameter plugged holes in the siding every 16 or so inches in 2 rows, one on each floor. We let the insulation cure/dry for a day or two before we painted the caps to match the siding color. In the end, we decided to repaint the whole house but only the main color, not the trim. I would suggest anyone with wood siding that has this type of insulation installed, consider the cost and time to paint the house because repainting just those plugs could be noticable if the house color has faded over the years. It is a very small price to pay (money and time) for the benefits we will see. There is a slight odor as the foam cured, but it was not toxic and not displeasant. It lasted about 48 hours before we could no longer notice the smell at all, but majority of the smell vanished in less than 24 hours. While it is too soon to discuss how well this work is saving us money, we did see 2 immediate changes: 1) It is much quieter inside the house now. 2) The upstairs is no longer a heat trap with unbearable heat in each bedroom (home has no central heating or air conditioning). Let me add a 3rd change now that we have experienced a few cold evenings: 3) The house is indeed warmer and retains so much heat when the radiators go on. The radiators did not have to stay on long before the house maintained a good temperature. USA Insulatoin, as part of their energy audit, left us with several suggestions of "do-it-yourself" projects that can provide additional energy savings in addition the major savings we will see from this insulation work.
Energy Efficiency Auditing questions, answered by experts
Common warning signs of an overloaded electrical panel or meter box include frequent circuit breaker tripping, flickering or dimming lights, scorch or burn marks, and a burning scent coming from the panel. A circuit breaker trips as a protective measure to prevent overheating and potential fires. If you observe any of these signs, turn off the affected circuit breaker and move some devices to a different circuit. If the problem persists after turning the breaker back on, you should contact a professional electrician to resolve the issue.
While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.
Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.
An average, 400-square-foot electric heated driveways consume approximately $3 per hour in terms of electricity. The price may slightly fluctuate depending on your local energy cost. A simple formula to calculate your heated driveway’s total wattage consumption is by multiplying the square footage by 50 watts and then dividing it by 1,000 to get the kilowatt number. Multiply that with your local energy cost per hour and there you have the hourly operating cost.
