Keeping You in Your Comfort Zone Since 1902


In 1902, two important things happened to make you comfortable.

In 1902, Willis Haviland Carrier designed the first modern air conditioner, an invention that led to major changes in the way we live indoors. We enjoy such things as comfortable workplaces, movie theaters, and indoor basketball games because of Carrier’s invention. Perhaps more importantly, you can go about your daily activities in your home, comfortable in an environment that has even humidity and temperatures.

In 1902, something equally important happened in St. Joseph, Michigan, that also makes you comfortable: the folks at City Plumbing, Heating, and Air Conditioning were establishing a family-owned business that now serves all of southwest Michigan. For more than a century, City Plumbing, Heating, and Air Conditioning has carried on Wills Carrier’s spirit of innovation and intelligent problem solving.
