THE Dietrichs

The year was 1960 and Ralph Dietrich and Richard “Bing” Miller were working at Standard Furnace in the sales department. They had a common belief that the HVAC contractors of the Omaha area deserved a better option to get their sheet metal needs. So Wholesale Heating & Cooling Supply Company was born.

The first location was downtown in what was called the “old ice house”  building. They operated there until late 1969, when they built a 15,000 square foot building at 85th and Park Drive near Ralston.  As the business grew, they add 7,000 square feet in the early 1980s and John, Ralph’s son, started to work full time for the company.

In the late 1980s Ralph bought out Bing and John and took over the accounting duties. For the next several decades, they expanded their delivery territories to include most of eastern Nebraska and western Iowa. They also expanded the products to include commercial and residential lines for the HVAC contractors. John took over running the business in the mid-1990s, and in 2010 Tom and Jake, John’s sons, came on board to help continue their father and grandfather’s desire to provide quality products and service at a reasonable price. In 2019 they moved to the current location at 7820 F Street. This move provided them with the space to grow the business and take on new product lines by almost doubling their square footage. Tom and Jake look forward to taking over the company one day and continuing the family business.
