Thermal Heating Air Conditioning and Refrigeration began with a simple yet powerful mission: to bring dependable heating, ventilation, air conditioning, and refrigeration services to homes and businesses in South Chicago Heights and beyond. What started as a small operation has grown into a trusted name across Illinois and Northwest Indiana. Our team is composed of licensed, experienced professionals who care deeply about doing the job right—whether it’s a residential furnace installation, commercial chiller repair, or full HVAC system overhaul.
We believe in showing up on time, communicating clearly, and leaving every job site better than we found it. Our clients include homeowners, restaurants, medical facilities, and industrial companies, all of whom rely on us for critical refrigeration and HVAC solutions. We’ve developed a reputation for fast turnarounds, long-lasting results, and fair pricing. No matter the size of the project, we deliver with precision and pride. At Thermal, we're not just technicians—we're problem solvers dedicated to keeping your environment comfortable and energy-efficient all year round.
