OUR REVIEWS
Customer Reviews
Don't just take our word for it. Actual quotes for actual customers.
  • Very prompt and efficient. My furnace went out and they came the same day I called to make sure it was up and running.
  • Thank you! I appreciate the awesome service and work you provide for me.
  • The fastest, most professional and expedient response for service that I have ever experienced! I have used their services for both heating and cooling emergencies and have always been extremely satisfied with the outcomes! They come highly recommended from me.
  • Thank you for everything! Your guys did a great job. I will be contacting you again for additional work.
  • This company is great! I use them at my office every time we have an issue with A/C. They are quick to respond to ER issues, even non-ER issues! Office staff is very friendly. Every technician I've met is also friendly, tells you everything they found wrong and replaced. Also will give you suggestions on what should be done, and will never try and up-sell you on anything you don't need.
  • I work for a Major School District with many items from Milk coolers to dishwashers. We were recommended them from a vendor whom we had purchased parts from that use them as their regular service company.  After three different types of repairs were done I have entered them into my phone tree as the first call out as well as letting our other techs use them for their buildings. Service was responsive, well explained, and POLITE!
  • I have known these guys for over 10 years. I used them for my business and now I have them service my home.   A few years ago, my heater went out on Xmas day and it was 30 below out. Yikes! They came out ASAP and got us up and running. Their prices are fair and the job is always done correctly the first time.
  • Your men were so kind and thoughtful. It is so hard to find good workers who are clean-cut, know their jobs, and do it like they enjoy their work. I would recommend your company on the basis of these fine men. Thank you for sending them to do my work.
  • So, that one hot day in a long time and guess whose AC broke down… This guy’s! Well the good news is it’s getting fixed by my favorite company, Northeast Illinois Heating & AC. These guys rock. Heating, Air and anything else you might need. Call these guys if you need anything fixed.
  • It is apparent that your team is running an honest business that really cares about its customers. You really took a difficult situation and made it better for my family and I. We are truly grateful. Keep up the great work!
