Paragon Insulation has done an excellent job for me twice this year. The first time in January, I…read morehad Randy come out to quote attic sealing and insulation. While he was there to provide the quote, he noticed the kitchen floor was really cold (he took off his shoes when he entered the house). He pulled out his thermal camera and we saw the floor was 30-40F! I had noticed that area of the kitchen was cold in winter, but didn't realize it was coming from the floor, where kitchen is cantilevered out past the foundation wall. He proposed insulating the cantilevered area with spray foam, and then said he could insulate all the rim joists in the basement for the same price. A week or so later, while he was onsite doing the insulating, I mentioned I was going to finish the basement later in the year, and expected to use 3 inch foam panels. He suggested using spray foam instead since that would give me a few inches more space in the room. He gave me a price and I said I'd think about it. As I thought about it, I realized getting a few more inches in the room, and also getting a better sealing product would be worth it, and would save me many hours of labor and a lot of material costs. In summer, I started work on the basement project, and once I had the framing up and electrical roughed in, I called (now July) to schedule the spray foam. Randy honored the price from January, scheduled the job quickly, and it looks great! Something I especially appreciate about Randy and Paragon is that the guy who quotes the job actually does the job; it's not some sales guy, it's the owner who quotes AND does the work! Because of that, any questions get answered and you know exactly who is accountable for quality and completion. I did get other quotes for the attic, and Paragon was very competitive. I really appreciated Randy's suggestions, and they did not feel like a sales pitch; it felt like I was getting good options to consider that would solve a problem I had.

But when those areas need attention, it's essential that the work is done right and by someone you can trust. Randy and the team at Paragon Insulation & Services delivered an experience I'd recommend to anyone. My attic was poorly ventilated -- damp, musty, and overdue for attention. After deciding to bring in a professional, Randy came out to my home, thoroughly assessed the problem areas, and put together a detailed quote on the spot. The scope of work included removal of the existing insulation, air sealing around all attic entry points, sanitizing, air baffle installation, and installation of new Weather Blanket cellulose insulation. The new cellulose achieves an R-value that meets or exceeds Illinois code requirements. Paragon's pricing was competitive, though admittedly a bit higher than some of the larger corporate outfits. What made the difference was Randy's willingness to walk me through the entire plan and clearly explain what justified the investment. That transparency, combined with the comfort of working with a local, owner-operated business, made the decision easy. The crew came in and completed the job in about half a day -- fast, efficient, and clean. The entire process was documented with photos and videos, all of which were included with the final invoice. While up in the attic, they even took the time to correct some substandard work a prior contractor had left behind on my bathroom exhaust fans. I couldn't be happier with the results. I've already noticed a meaningful improvement in temperature consistency and overall comfort throughout my home. If you're looking for a trustworthy, professional insulation contractor, I wouldn't hesitate to recommend Paragon Insulation & Services.

I know he didn't try to upsell or provide unnecessary services as a prior serviceman told the home warranty company the same thing and I knew it was not covered Steve fixed the issue and cleaned the heater within 1.5 hours.

Steve's office called seconds after the claim was filed, I had not even gotten off the call with the warranty company. That's some fast office work! Unfortunately no same day appointments were available so they set up a next day morning appointment. Steve showed up on time and brought all the necessary tools and parts for the repair. He was nice to speak to and highly focused on his work. The job was completed quickly and Steve avoided conversation until he finished the repair so as to maintain focus and reduce delays in the repair due to chatting. Having no A/C is no fun! Some reviewers mention rudeness and arrogance, we got none of that, maybe he was having a bad day on those service calls. He was very quiet during the repair process but pleasant and easy to work with at the end of the repair process. If you are looking for an HVAC contractor who knows their stuff Steve's company is a good choice to look into!

I first hired Air Kings to install a new AC unit at my home late in the season 2024. Although that…read moreunit needed service in just the first full season of use, I still felt pretty good about Omar and his company. I purchased two seasonal maintenance checks from them last year. During the 1st maintenance check in November 2025 he had informed me that the blower motor in my furnace was leaking oil. But I declined service at that time and my furnace worked fine all winter. When he came for the 2nd maintenance check on May 6 he told me the blower was still leaking oil and should be replaced. But he also said my 13 year old furnace was old enough that I should just get an entirely new furnace. Either option was a very big expense and I needed to consider what to do. But the very next morning the heat did not come on, it was 60° in my house with the thermostat set at 67°. Omar came back out and he was clearly annoyed, a major change in his personality. He showed me a blinking light on my furnace, told me it was a malfunction code that confirmed I needed a new blower motor. I told him it was a very bad and uncomfortable coincidence that my blower motor suddenly didn't work the morning after he had done the seasonal maintenance. He became very angry, raised his voice and said "What are you trying to say?! I don't like what you're accusing me of!" His belligerence was very unprofessional so I told him I would get another opinion and asked him to leave. Two hours later a technician from a different company told me my blower motor was sealed with internal lubricant and was not leaking at all. He also said my furnace was nowhere near old enough to need replacing. As I watched, he tested a capacitor that had failed and replaced it, which totally fixed the problem. It took 10 minutes at a total cost of $225. If Omar had been honest with me I would've bought that capacitor from him and he would still have me as a customer. Because I trusted him. And that was my mistake. There are only 2 possibilities- Either Omar totally misdiagnosed what was wrong with my furnace and really did believe the only option was to replace the blower motor, if not the entire furnace, OR he simply wanted to sell me very costly repairs I couldn't afford. I don't know which is true. But he does. Needless to say, I would never do business with Air Kings again.

I decided to go with Herchenbach Mechanical after comparing a couple other places in the area. Scheduling an appointment was easy. Curtis and his team came over and installed the AC unit fairly quickly. They were very professional and courteous. Fast forward to a few days ago, my kid decided to throw pieces of chalk down the pipes. I called Herchenbach Mechanical to schedule a time and date that works for me. They will email and text you to confirm your appointment. On the day of your appointment, they will also send you a photo of the technician that will be over. Adam, the technician, was very friendly, knowledgeable, respectful and on time. I told him what happened and he explained what he would need to do to get the chalk out from the pipes. I also scheduled them to clean my AC as well. After Adam finished using the hose from the backyard, everything was neatly put back the way it was. He didn't leave anything out or left a mess. When he was inside the house, he would immediately put on those disposable shoe covers without me having to ask. Herchenbach Mechanical has always provided great, friendly service when I needed them. I have nothing but good things to say about Curtis and his team. Again, highly recommend them! You won't be disappointed.
