Roberto came out, did a blower test, comprehensive walk thru with the thermal camera and we talked about issues and what solutions would work. We came up with a plan. Got started, and discovered an issue. We got together and pivoted to a very workable solution to get the job done. Work was completed well, quickly, and when they were done they cleaned so well you'd never know they were there. Very pleased with the results. Very pleased with their professionalism and ability to find solutions. Couldn't recommend any more strongly!!

The team was professional, friendly, and patient. There was good communication between the team and me.

My attic was underinsulated, so I knew what the issue was, but I wasn't sure about which company to trust. I contacted a few companies, and AARCO was the first to respond and schedule a visit. In general, getting in contact with Chris was easy, and he was quick to respond to all my emails. The day of the insulation was smooth and fast. Their machine was really quiet, so it didn't disrupt anything. My attic is now at R49, and my bills are lower, even with the recent ComEd rate hikes.

I am not sure how long ago my home was insulated, and it's a 100 year old house. Jaime and Alvaro were extremely professional, always polite and made sure everything was spotlessly clean when they were done.

I am looking forward to a warm home and reduced energy bills this winter! Thank you!!

Randy and his team did a great job on our attic and crawl space. We had ice dams bad this winter,…read moreand my house looked worse than the neighbors'. One night the heat went out and the indoor temp dropped to 49 degrees, so that sealed the deal, we needed better insulation. They also encapsulated the crawl space with spray foam. Turns out there were mice living down there that we had no idea about. One even fell on a worker while they were pulling out the old stuff. Made sure to tell my wife who was on the fence originally about having this done. Big difference since then. No more mice sightings, heating bills are noticeably lower, and the house stays comfortable even when it's really cold outside. Solid work all around. I'd recommend them if you're dealing with the same issues.

I live in a ranch home built in the 1950s - a fairly common build for the Chicago area. ARC…read moreprovided a quote ( without visiting our home) that included the following sentence, "Please confirm exterior walls are framed 2x4". I told the rep that other companies have inspected our home and stated that our walls are suitable for blown in insulation. ARC never came to visit our home - while their competitors did this as a standard account management cycle. Fast forward to this week, I was ready to sign the agreement and pay the deposit - the rep asked me to confirm the 2x4 framing. I asked him how he wanted me to do this - he suggested I drill pilot holes in each wall or pay a 3rd party to do this and that ARC was not responsible for verifying the details of our home. Not responsible for validating a critical project detail before having you customer pay thousands of dollars?! Extremely poor customer service and frankly, a lazy sales team. I am sure the crews doing the work are great, but the accounts team could use a refresh. I will work with a competitor unless ARC has employees willing to visit their prospective customers!

He was able to help me convert my garage to a gym by insulating the roof for me - which has made it possible for me to work out in the winter there.

Our inspector…read moretold us the insulation looked like it hadn't been refreshed in 40 years and was severely deficient by modern standards. Jim was one of a few companies that I received estimates from for insulation, but he was far and away the most thorough and descriptive. As a first time home owner, I didn't know a shingle from a soffit - Jim made the whole process easy to understand. Further, his report on our home after the estimate was like a graduate thesis, but in layman terms. I'm far more educated about my home after working with Jim, and I finally have adequate insulation in my attic and crawl space. He was also reasonably priced (competitive with another estimate and 1/3 of the most expensive estimate that we received). TL:DR - I would recommend Jim and his team to anyone looking to up their insulation game (he also does HVAC and Solar, although we weren't in the market for these).
