“I noticed my air conditioner was out I called Illiana to come out and look at it, they sent David K one of the managers because they were all backed up and he had it fixed within 10 minutes.I can't say enough good things about Illiana heating.”
“Illiana replaced my air conditioner and furnace this week. Two young men did the work and they were great. Misha, who was in charge, was very nice and professional. They did a great job and cleaned up the mess from having to remove the old ac and furnace. Very happy with the work they did!! Ann”
“AC went dead after 23 years. Dan K came to my rescue. I am 75 and on a fixed income. Dan gave me a great price and no hassle. Scheduled for the next day between 11 and 2.
Steve and Jacob arrived the next day right on time. They were great. They did a great job in 2+ hours. They were professional and explained to me all that they had done and made certain that I was satisfied.
I have been a loyal customer for over 20 years and I would highly recommend Illiana heating to everyone I know.
Thanks Joel”
“Adam and Matt did a Great Job on the Installation. Thank you.”
“I am always happy to see Andre when he does my maintenance for my AC and furnace.
Always very professional and friendly, but mostly because he gets the work done well! Andre always asks if I need any questions, which I appreciate that very much.”
“Great job, from initial visit to working with the team on an estimate. We needed a new AC, Air Handler, & Humidifier. Great price, prompt service, and a great install leaving the house super clean and the system running smoothly! Thank you Illiana Heating!”
“Thank you Illiana for installing my furnace, air conditioner, humidifier, and thermostats! Adam and Steve did a great job testing everything, explaining how everything works, and answering my questions.”
“Andres performed maintenance on my HVAC system in October of 2024 for the furnace and recently on 04/21/25, on my AC to ensure my AC is ready for the summer season. Andres is very professional, explains what he will be doing, and answers questions that I ask during the service visit. He also reminds me of when my service plan needs to be renewed. He also treats my home with respect and dignity. Andres provides excellence in customer service and is a great asset to Illiana Heating and Air Conditioning, Inc.
Thank you Andres for the service you provide.”
“I contacted IH&C to get an estimate for replacing an AC and Furnace. Dan Krygsheld was the technician who showed up for the appointment. He was courteous, polite, professional, pleasant and easy-going. I outlined for Dan what I was interested in and why. He listened politely and asked to see the locations of the AC and Furnace. He explained the function and features of each component in what I call "everyday people speak": he explained things so a lay person could understand. That tells me that he genuinely knows his craft. As a result, we agreed for IH&C to replace our AC and Furnace. I asked about timing on installation and he said "tomorrow"! The IH&C guys showed up the next morning about 8AM and by 4:30PM we had a new AC and Furnace. No fuss, no bother. The IH&C guys went about their business without interrupting our household, cleaned up, reviewed the new installations with me and departed. Great experience with this company. Well done and thank you.”
