I just had my semi annual cleaning and inspection and Andres was very professional, explained questions I had about the furnace and took extra time to prevent any possible breakdowns with the cold weather. I have used Illiana for five years since I moved out to Cedar Lake, I don’t know why anybody would use any other company they are fantastic. When you call the office with questions or need to reschedule an appointment or have problems with your furnace they’re always so helpful. Thank you Illiana for representing the Christian company that you are. Paulette young

The entire staff from receptionist to sales to technicians was very professional. I had my furnace and air conditioner replaced with a knowledgeable and friendly staff. Quick response time. Salesman was very knowledgeable and provided several replacement options as well as set up a no interest payment plan for me while at my home. Communication via phone, text (that provided a photo id of technician)and e-mail were impressive. The whole process was quick and painless. Thank you Illiana!
