About Miller’s Area Heating & Air Conditioning

About Us

Miller’s Area Heating and Air Conditioning was founded in 1948 by two zealous hardworking men known in town as the Miller brothers. Jim and Ray Miller started with just one truck and a truckload of know-how and integrity. They found the town of Grayslake an ideal place to build their dream; so a location in the center of town was chosen as their business location, and after all these years the address is still the same.

In 1975, after 27 years in the HVAC business, Ray decided he wanted more of his time devoted to fishing and less time devoted to work; so he sold the company to Jim. Jim obviously had a plan of his own because at about the same time Ray sold his portion of the business, Jim’s son, John, was growing into just the man Jim needed to replace Ray.
