Air King Inc.

We’re Air King Inc., a family-owned and operated HVAC team since 1995. We serve Decatur, Illinois, and surrounding communities, and we’re honored whenever someone invites us into a home to care for their equipment. We approach that responsibility with honesty, a strong work ethic, and respect for the space. Our NATE-certified technicians are trained and experienced, service all makes and models, and focus on completing each job with care and clear communication.

We provide heating and air conditioning repair, installation, replacement, and maintenance for homes, along with commercial HVAC repairs and installations. Whether a furnace, boiler, or air conditioner needs attention, we work to identify the problem and determine an appropriate solution. We also install, repair, and maintain ductless systems, clean ducts, and offer indoor air quality products, including humidifiers, dehumidifiers, ventilators, air purifiers, and filtration options. When a repair cannot wait, our team is available for 24/7 emergency service.

Preventive care is another important part of what we do. Through our Peace of Mind maintenance program, our technicians visit in the spring and fall to inspect, clean, and calibrate HVAC equipment. We can also check for concerns such as clogged filters or hoses while working on a system. Our goal is to help customers keep their heating and cooling equipment in good working order and make informed decisions when repair or replacement is needed. We serve Bloomington, Champaign, Clinton, Decatur, Forsyth, Mt. Zion, and surrounding areas, and we’re ready to help with heating, cooling, ductless comfort, duct cleaning, indoor air quality, and commercial HVAC needs.
