Our roots are here
1950
Three generations.
One family name.
Having worked for Stewart Warner and Winkler, Paul Frederick Kays founded Kays Heating and Air Conditioning in 1950. Not long after, he helped establish Lebanon’s first HVAC licensing board and wrote its licensing test.
In the 1970s, his son, Paul Kays III, carried that legacy forward, shaping it into the family tradition it is today. Among the first to install geothermal systems in Boone County, he helped bring newer technologies to the community. He also succeeded his father on the heating board and updated the licensing test to reflect modern standards.
But his greatest achievement is the relationships he’s built over the decades. Through quality work, honesty, and personal care, he made our name one people trust—and made neighbors and customers feel like family and friends. That’s why they say, “Call Paul.”
Today, Paul is guiding the next generation alongside his son, Jared. Together, they’re carrying on the family tradition—and working to restore the personal service too often lost in the modern HVAC industry.
As more local, family-owned companies sell to private investors or grow away from their roots, neighbors can become little more than paying customers. That has never been us. It never will be.
For three generations, we’ve stood for quality work and an honest word. Without compromise.
