Grayco has been a family business since it was founded over 30 years ago. Tim and Julie Gray have built a solid reputation as a trusted business in Central Illinois as they are committed to providing quality service to their community. The Grays believe that a reputation as an honest and reliable business is the recipe for success. While others seek to profit by cutting corners, or recommending unnecessary services to customers, the Grays believe that a good reputation and consistent service will reap bigger benefits in the long run. Whether you need a routine maintenance check or an emergency repair on a heating or cooling unit, we are able to handle all of your heating, cooling, and ventilation needs. We continually strive to exceed expectations by ensuring that each of our clients receives the very best service. 


Tim and Julie both grew up in the Central Illinois area and have volunteered countless hours in their community. They have a passion for building relationships; therefore, they treat their customers like family. Tim began his apprenticeship in HVAC at the age of 18 and has worked as an industrial mechanical engineer and HVAC-R engineer ever since. He has developed a deep knowledge and understanding of running a successful enterprise. Julie has worked in the customer service area all her life and is always willing to help customers to the best of her ability. The employees at Grayco Inc. are factory-trained and are the best in the business.
