How Can We Help You Fix Energy Loss and Air Quality Issues?

Air ducts are often hidden behind walls, ceilings, or floors—which makes it easy to forget they need maintenance. But when those ducts have leaks or gaps, your HVAC system has to work harder. That means higher energy bills, inconsistent temperatures, and more strain on your equipment.
Our duct sealing service solves that. We inspect your ductwork from end to end, identify problem areas, and apply professional-grade sealants to close leaks and improve performance.

Here’s what you can expect:

A detailed duct inspection using diagnostic tools
Sealing of gaps, cracks, and loose joints
Airflow balancing to ensure even temperature control
Filter checks and ventilation system recommendations
A post-sealing performance test to confirm improvements

With us, you won't get a quick patch job. You'll get a customized fix designed to make your home more efficient and your air cleaner.

Protect Your Health, Budget, and Comfort with Sealed Ducts

Poorly sealed ductwork doesn’t just affect your energy use. It can also pull in dust, allergens, and pollutants from crawl spaces or attics. That air gets recirculated throughout your home, impacting your indoor air quality and potentially aggravating allergies or respiratory issues.

By sealing your ducts, you block out those contaminants and help your system deliver clean, filtered air to every room. It’s a smart move for families who care about their health as much as their comfort.

We’ve helped homeowners across Chicago enjoy cleaner air, better humidity control, and fewer HVAC problems just by tightening up their ducts. It’s a straightforward fix that delivers big returns—especially when done by a team that knows what to look for.

Real Proof That Smart Service Works

“Highly recommended and will definitely contact Intelligent Service again.”
Anthony C. was the technician who came to service my refrigerator and he was amazing. Very professional, polite and knowledgeable about the service I needed.

“Clearly this company has all of their ducks in a row, and can be trusted.”
At 3:00 in the morning my sump pump inverter started kicking on continuously, and I called they had a 24-hour hotline available. I chose to wait until normal business hours to have somebody come out, and they came out within 2 hours of opening. My technician was knowledgeable, gave me great advice, found the problem instantly, and then replaced it within an hour.

“I would fully recommend Intelligent to anyone with an old home that perhaps was not updated correctly in the past- and needs a creative thinker to solve your weird plumbing problems.”
Edgar from Intelligent Service was the best plumber I've ever had. He was kind, courteous, and a great problem solver. As with most repair jobs, once you open that wall, a million unexpected things go wrong. Edgar solved every problem and did so in a way that kept the job from turning into a massive beast of torn out tile or cut-outs behind cabinets, blah blah blah. I would fully recommend Intelligent to anyone with an old home that perhaps was not updated correctly in the past- and needs a creative thinker to solve your weird plumbing problems.

Also- the person who called me to schedule everything and check on times was very well spoken, kind, and competent- something I unfortunately have found lacking in many repair service companies of late. So kudos to the office side of this company as well!

“We’ll definitely look to Intelligent Service again for any plumbing issues. Thank you so much!”

Brian was very friendly and knowledgeable. He explained the problem, our options, and what his recommendations were. He worked very fast, too, and we ended up paying a little less than what was originally estimated. He also made sure everything was put back together and even cleaned up afterwards. We are very happy with his service and appreciate his professionalism. We’ll definitely look to Intelligent Service again for any plumbing issues. Thank you so much!

“They've earned a customer for life!”
I'm new to the Mount Prospect area and am very happy to have stumbled upon Intelligent Service for my plumbing, heating, and cooling needs. I am a first-time homeowner and used Intelligent to fix several of the problems that were found on our home inspection. Every single person who has come to my home from Intelligent has been super kind, knowledgeable, and excellent at what they do. As a woman, I also love that they send a picture of the service technician you can expect to come to your home as an added safety feature.
