"Arc was great from the start. We were given a complimentary consultation by Steve Garrett, who gave us a detailed explanation on the issues we may have with our attic insulation and why our energy bills may be so high. We chose to have our attic insulated and our ducts sealed. Our ducts saw a 93.5% improvement, and we immediately noticed the difference in the temperature of our second floor. Even during this prolonged heat wave, we have been able to keep our temperatures much lower than before. The attic insulation has also decreased the temperatures of the upstairs. It has been a remarkable difference. We are fully expecting our house to be more comfortable in the winter as well. Steve is honest and reliable and we would not hesitate to recommend Arc to anyone who needs insulation and duct work."

"Attic Air absolutely lived up to their reputation. They did a GREAT job! I did my research in creating a short list of 3 bidders for the job. I have a bi-level house (4 levels) with 2 attics. We had black mold on the underside of the roof which we had remediated a week before having Attic Air come in to fix our ventilation and insulation issues. Our upstairs floor was cold in the winter and hot in the summer. The attic ventilation and insulation needed to get fixed, and I wanted to make sure I hired a good company to do it the right way so I never had to worry about it again. I made the right choice. The temperature throughout the house is so much more even now. Before Attic Air came out, the basement and sub-basement were freezing and the first and second floors were warm and hot. My over-sized top of the line Trane a/c unit was working overdrive to try to cool the 2nd floor and never could do it. The top floor is so much cooler now than before. It's really going to save my a/c unit in the long run. Attic Air was not the lowest bid of the 3, but you get what you pay for. If you want to get the best quality this is the company you want. I would haven't have changed a thing. Worth every penny!"

"I am very happy with the work done by Green Attic Insulation. David and Charlie were very friendly, professional, responsive, and flexible in working with my changing needs. I originally was looking into insulation but then discovered there was mold in my attic. As the job grew, David, Charlie, and their team worked with me to address the additional parts of the job. I really appreciate their knowledge and the thorough job they did. They took many pictures of their progress and kept me informed each step of the way. Thank you very much!"

"It went fairly well. The man in charge of giving estimates gave me confidence. The man in charge of the work was a bit of a fast talker, however. I have waited over a year to finish this review b/c I wanted to wait until I got door into the porch from the house and for cold weather to see how well the insulation works. I do not have a heat vent on the porch. Was hoping the insulation along with a small electric heater would keep it warm. The contractor thought it would be okay without a heating vent. For most part it is, but with very cold weather, the porch gets pretty cold. I may have been hoping for more than was realistic and may eventually get a larger electric heater or get a vent from my furnace if I decide to use the room more regularly."

"The gentleman who came and did the energy audit was really outstanding. I have only lived here for a year and half and I have a gas fire place has leaked cold air like there is an open window and my builder has just been refusing to fix. Finally after a second winter of no fireplace I decided to have to repaired. I wanted to have an energy audit done before and then I would decide maybe to sue the builder. When Angelo came from Intec and I told him the story, he said that before the audit, he would tell me what I already knew, that my fireplace was leaking air like an open window, so he suggested that he would come and do the audit after the fireplace was repaired to make sure everything was right. He came, he told me this and he rescheduled to come back a week later. He did a very nice job. My only concern is he told me that he would send me the report, I thought that he told me that I would have the report by the following Thursday, and I have been busy and haven't followed, but I don't expect there to be an issue when I call. There are a couple of things he had suggested that I would have to have insulated better, and I would like to have those fixed. He came when it was originally scheduled and he came a week later, and I had offered additional payment for that, but he said absolutely not. While he was here, he really took time to explain to me in much greater detail than the previous guy. When he talked to me about the couple of areas where there was leakage, I asked if it was possible to have it fixed without going into the roof, so he went into the roof. He was very professional, personable, and thorough. I feel like when I get that report, and the 3 three things that he had told me, if it is something that the company can repair, I am pretty confident that I will use them."

Over time, you’ll notice lower utility bills, less strain on your HVAC system, and improved moisture control.

Helpful?

After insulation service projects in Naperville, inspect air sealing around windows and doors, and ensure attic and crawl space ventilation is adequate.

In Naperville, schedule insulation service projects promptly if you notice high energy bills, frequent ice dams, or persistent drafts—especially after harsh winters. If you see uneven room temperatures or visible mold, act quickly. For minor issues or if you’re planning renovations, you can wait, but consider local weather patterns and aim for spring or fall when conditions are ideal for installation.

Helpful?
