    Adam C came across as highly competent, respectful, and efficient. He got the job done quickly and left everything tidy, also taking the time to educate me on maintaining my new furnace effectively.

    We've been loyal customers of Illiana Heating and Air Conditioning for decades. Recently, we needed a new furnace and AC system, which Dan helped us with by sending over recommendations and pricing options. I met with Dan on a Friday morning to discuss our choices and get answers to my questions. He provided valuable insight that helped us select the perfect system for our home. The installation happened three days later, on Monday, and the technicians, Adam and Jacob, arrived promptly at 8 am. They explained their plan of action and worked efficiently throughout the day to complete the job. Adam took extra care to ensure the fan speed was just right. We're grateful for Illiana's honesty and exceptional service over the years - a true testament to their professionalism.

    I've found a reliable service provider for my HVAC needs - Illiana is great. Their technician, Alex, was courteous and skilled, doing a fantastic job fixing my furnaces. I'm eager to have them return next spring.

    I recently had to replace my HVAC system in my new home, which was a hassle. Jerry B came out to assess my old unit and found it wasn't safe to run due to a hole in the furnace - not their fault, just a design flaw. Dan K followed up with a fair quote the same day, which was convenient. The work started and finished on the next day, done by Adam and a colleague who were courteous and diligent. They respected my property and showed me both units when they were completed. I now feel confident in my new system's performance and have peace of mind with its warranty coverage. I'm glad I chose Illiana Heating & Air Conditioning for this job - they did it right!

    We're thrilled with the recent upgrade to our home's heating and cooling systems, courtesy of Illiana. Our 22-year-old furnace and AC unit were on their last legs, having failed us last year. So, when we decided to get new units, we wanted to make sure we got the best deal. Illiana delivered not only at a competitive price but with top-notch equipment. From the start, Michael's initial visit showed us that they're a company that values professionalism and customer service. He was friendly, courteous, and efficient, making the estimate process seamless. Dan took it from there, working patiently to understand our needs and delivering exactly what we wanted at a fair price. Kevin followed up with accurate measurements the next day, and the installation team did an outstanding job. What impressed us most was how they went above and beyond. They not only installed new lines, redirected duct work for better access, and upgraded our AC unit – but also improved the overall appearance of our furnace room. We were surprised to find that they'd upgraded our drain hose and water lines to our washer and dryer without charge. As a contractor myself, I can confidently say that Illiana exceeded expectations in every way. Their expertise, workmanship, and customer-centric approach make them an exceptional choice for anyone seeking HVAC upgrades or maintenance. Don't hesitate – contact Illiana; you won't be disappointed.
