“This is a good company. They treat their customers well. Tony came to my house today. He was professional and did a great job.”
“Our 5 STAR recommendation for the Illiana Heating & Air Conditioning, Inc. team. Great cooperation and work.
It all started with our phone call to their office in mid-June 2025. Our AC was not working properly. Patty helped us from the beginning. She gave us a choice of 1) a diagnostic service visit (next day) or 2) full repair service (four weeks out). We opted for the next day, which was actually an “emergency” service trip assigned by service address location to be as efficient as possible. The Illiana office stayed in touch with us during the day and gave us about an hour's notice of the visit time (no actual appointment time). This was immediately confirmed to us via text.
The next day, their text messages started at 7:33 AM, just saying we were on the day schedule and they would give us about an hour’s notice before the technician would arrive. Another message came at 10:03 AM, and the next at 1:01 PM. At 2:58 PM, Jerry B, Illiana’s Technician, sent notice he was on his way. The notice included an introduction and the technician’s photo for identification.
Jerry got to work right away, starting with the indoor system and then the outdoor system. He took several measurements and found a few values that did not add up. He went back into the furnace and accessed it with a scope camera. He found that the refrigerant valve was not functioning. Jerry was able to quote the replacement part and labor cost right there. However, he also noted that our Heating & AC system had been installed in 2008, making it 17 years old. We asked what a replacement AC system would cost, and Jerry referred us to Dan Krysheld for this system estimate. Jerry took photos and measurements and sent them to Dan, making an appointment with him in two days.
However, later that day (early evening), we received a text from Dan asking to clarify a couple of items. We did this, and in less than an hour, we had a complete proposal, which included an A/C system change-out and a Furnace with an AC change-out. Illiana promised to schedule the change-out within two workdays. Since the existing system was 17 years old, we decided to replace it all.
The installation was scheduled for the promised time, and Adam and Sam were at our house, ready to go a little before 8:00 AM. They worked together like an organized team should. They positioned all the new equipment, with one taking the outside and the other taking the inside. They worked efficiently and made the installation look very professional. They redid piping, furnace intake and exhaust, wiring, ductwork, and monitoring. The complete cleanup was done with care and thoroughness, including sweeping the floors. They were done around 3:00 PM and then took the time to explain the system’s operation and the new components.

“Thank you, Misha S and David K for quick response today on fixing my air conditioner.”
“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.”
“I would like to thank Jacob and Kentrell for a very good job and taking the time to explain any questions we had for them and cleaned up Very good after they were all done”
“Professional courteous and most importantly trustworthy, best we’ve had here!!!”
“I was pleased as usual with the technician who maintained my furnace for the coming winter months. I cannot remember his name, but I was very pleased with his work, as I always am with your folks who also service my A/C in the summer.
Thanks again,

“Excellent service and very polite and friendly. I also appreciate the effort by ILLIANA Heating and Air Conditioning Management to ensure my safety by sending a photo and name of the service technician BEFORE he arrives at my home so I can ensure I am safely letting in the correct person to resolve my heating and/or cooling issue. I highly recommend ILLIANA Heating and Air Conditioning!”

“This was our first time using Illiana Heating and I’d give them a thumbs up. Our service tech Andres was very professional, courteous and knowledgeable when answering our questions. I would definitely use them again and refer them to friends and family. We actually signed up for the Goldstar service plan with them.”
