    We had DeKalb Mechanical come out and replace our 30+ year old AC and Water Heaters. They came out and worked quickly and efficiently and we had everything updated within a few hours! Nathan registered everything and got us all the rebates and discounts available and we're very happy with both the final price and the work that was done. We would definitely recommend them again.

    We had an excellent experience with Dekalb Mechanical from start to finish. Their technician arrived exactly on time and replaced our heat exchanger efficiently and professionally. He used a camera to show us the inside of the unit, showing the cracks, and indicating a clear need for the part replacement.
    The technician was knowledgeable, straightforward, and honest—qualities that can be hard to find. It was truly a pleasure working with a company that values professionalism and transparency. We are so glad we found Dekalb Mechanical and would highly recommend them to anyone in need of HVAC services.
    Thank you to the entire team at Dekalb Mechanical. If you’re...read full review

    We got our new AC unit installed by Onon and we couldn’t have asked for a better technician or company to do it. He was professional and friendly during the whole process and we couldn’t have had anyone better! Definitely a great and responsive company who also follows up and makes sure it was done correctly! Will definitely use them for future needs as well!
