<h3>White Rodgers: Over a Century of HVAC Innovation</h3><p><strong>White Rodgers</strong> has been a cornerstone of the heating, ventilation, air conditioning, and refrigeration (HVACR) industry for well over 100 years. Founded in 1913 as the White Rodgers Electric Company in St. Louis, Missouri, the brand grew from a local electrical parts supplier into one of the most recognized names in climate control. Today, White Rodgers products are installed in homes and commercial buildings across more than 100 countries worldwide.</p><p>In 1966, White Rodgers was acquired by Emerson Electric — a Fortune 500 company also rooted in Missouri — gaining access to world-class research facilities and a global distribution network that accelerated the brand's reach and innovation. White Rodgers has since become part of the Copeland family of brands, carrying forward a legacy of engineering excellence in HVACR controls and components.</p><h3>A Legacy of Industry Firsts</h3><p>White Rodgers has a long history of pioneering products that have shaped the HVAC industry. The brand introduced one of the first automatic thermostats for residential use in 1960, and later developed the first user-friendly digital programmable thermostat in 1983 — a breakthrough that put scheduling control in the hands of everyday homeowners. White Rodgers also became the first HVACR manufacturer in the United States to earn ISO 9001 certification, reflecting a deep commitment to quality systems and processes.</p><p>Beyond thermostats, White Rodgers has consistently delivered critical system components that keep heating and cooling equipment running reliably. Their lineup includes gas valves, furnace controls, ignition modules, sensors, transformers, and an extensive range of <a href="/7649-white-rodgers-hvac-relay-17497">HVAC relays</a> — all engineered to meet the demanding standards of both residential and commercial applications.</p><h3>Reliable Controls for Heating & Hot Water</h3><p>White Rodgers also manufactures a respected line of <a href="/7649-white-rodgers-water-heaters-201162">water heater controls and gas valves</a>, including their innovative INTELLI-VENT™ technology, which combines gas valve, ignition control, and thermostat functions into a single integrated unit.
