“A couple of years ago, a technician from Illiana advised he discovered cracks in my heat exchanger on a furnace that was just 3 years old. Photos alleged to depict that, and it was suggested to purchase a new furnace. I had just purchased a new furnace for my main, and this other furnace is for an addition, so I was in disbelief that this 3-year old furnace was damaged. Fast forward to a few weeks ago, and I had a technician come out to clean and check my main furnace. Kentrell was that technician, and he performed that service. I inquired about the second furnace to see if he was able to check on it as well since I have a maintenance plan. He advised his work order only showed 1 furnace, but he agreed to check the other furnace out. I hovered because of my concern for this furnace, and he could not find any cracks. His willingness to check, and spend the time investigating was great customer service! He made phone calls to the office to update them about this, and he said the G.M. was going to send another technician out to confirm whether or not there were cracks. Jerry B came out to check it out and confirmed that he could not find the cracks depicted in the original photos. I was then contacted by the office to schedule the maintenance cleaning for this 2nd furnace and was advised that Kentrell would be back to perform that service.
Kentrell is a great young man with a willingness to seek the truth for my benefit, and he deserves to be recognized and given his bonus compensation!”
“Spent 15 K on a new HVAC system and have had nothing but problems. Heat has gone out on us 2 times in less than 2 years. And to top it off they charge you for the service call on a brand new system.”
“Your technician Kevin came out to repair my furnace. He was extremely knowledgable and professional. The technician was Kevin and I would highly recommend him and Illiana Heating and cooling!”
“Jerry my service man was very pleasant.”
“Schedule was spot on and day of scheduled appointment, kept me inform on arrival time of technician (Jessica). Technician was very professional and helpful (Chris L) and informative on various service plans available. Will continue to involve Illianna for HVAC needs”
“As usual, the routine maintenance service I received was top notch! From communication about the initial appointment to when the technician, Kentrell, was going to arrive to the time he spent thoroughly cleaning and inspecting everything, the entire process was very smooth and professional. Thank you for excellent service!”
“Chris L was very efficient, knowledgeable and informative when he cleaned our furnace! He is an asset to the company! Thanks Chris!”
“Andres serviced my AC 8/28/25 and gets a 5-star rating from me. He was courteous, knowledgeable, and efficient. He explained everything very well.”
