D & H Refrigeration Inc

D & H Refrigeration Inc has kept Chicago-area businesses comfortable and running since 1994. Based in Homer Glen, Illinois, this full-service mechanical contractor holds a 3.9-star average across 14 customer reviews and operates around the clock, every day of the year. The company primarily serves commercial and industrial clients across Chicagoland, including the northwest suburbs, providing refrigeration system installs, HVAC repairs, and specialty welding for food processing facilities.

What distinguishes D & H from typical HVAC companies is their industrial-grade specialization. They handle ammonia refrigeration systems common in large cold storage operations and commercial supermarket racks, going well beyond standard residential AC work. Their MechCare program replaces templated maintenance with individualized system care, and their union-trained welders earn x-ray certification to United Association standards, a credential that ensures leak-free joints in high-pressure process piping for steam, ammonia, and industrial layouts.

Customer reviews name specific technicians and scenarios that illustrate their responsiveness. Gayle Voss describes Ed arriving promptly to her restaurant, fixing the refrigeration issue on the first visit without follow-up calls needed. Slaid Gray notes his old technician retired and "Scott and Brian filled the void seamlessly," with office staff delivering quotes quickly. Joe's brief account of an emergency situation was resolved successfully, with Ed's repair work getting the business back up and running.
