Our history

In 1919, then known as the International Oil Heating Company, we helped St. Louis, Missouri, breathe easier by introducing oil-burning heaters to help alleviate the pollution that covered the city in a cloud of smoke.

Since then, our history has been shaped by groundbreaking HVAC solutions. From developing the first oil heater and sealed combustion furnace for manufactured housing to introducing an online ordering system when most people still thought fax machines were a pretty novel invention. So you could say that we’ve built a pretty extensive legacy of innovation on our way to becoming the best HVAC manufacturer.
