For over 100 years, Williams has designed and manufactured quality heating, ventilation, and air conditioning products for both the home and business. It all started in 1916, when Jesse Williams began building gas steam radiators in Los Angeles under the banner Williams Radiator Company. Williams’ commitment to quality was clear from the start, and the company’s product line expanded over the next few decades to include gas-fired heating, gravity wall heating and counterflow furnaces. By 1954, Williams had expanded to a nationwide player, with a distribution and sales network that reached customers throughout the United States.
Williams reputation for quality products only increased, and in 1958 they were acquired by Continental Materials Corporation, an AMEX-listed company whose notoriety brought new levels of prestige to the firm, now called Williams Furnace Company. The company acquired Hydro-Aire/LANCO in 1986, a major manufacturer of fan coils and air handlers. As a result, Williams now offers more fan coil sizes and configurations than any other HVAC company in all of the United States. Finally, the product line was expanded in 1996 to include room console heaters.
Jesse Williams understood that his company had to adapt to grow, and so do we. Today, numerically controlled machinery is used to ensure both precision and quality. All Williams products are tested to the highest standards according to specifications set by the National Bureau of Standards. Engineering, R&D, testing and manufacturing take place at our factory in Colton, California.
Above all, we aim to treat the customer with respect and integrity to ensure that our customers come to expect the same quality from us that they will from our fine line of products.
For nearly 100 years, Williams has offered a wide range of safety-tested, cost-efficient heating solutions to fit any home. From a studio apartment to a palatial estate, we’ve got you covered with a complete line of heating products, including both gas and electric furnaces. Come inside, and let Williams warm you up.
