About PDM Plumbing, Heating, Cooling Since 1885


AC DillmanFounder of PDM George Poehner

133 years ago Mark Twain publishes the “Adventures of Huckleberry Finn" and the Washington Monument was dedicated. That year George Poehner opened his own no excuses hardware business. He was driven to work the right way, not the easy way.

Then in 1890 Sherlock Holmes publishes a number of books, " Ellis Island (NYC) opens as a US immigration depot and Plainfield native AC Dillman joined George Poehner as a partner. They expanded indoor comfort products-services and the firm became Poehner & Dillman Company (P&D).

This was a time when indoor plumbing and heating began to evolve. The first dishwasher was invented by a woman in Shelbyville, IL. The first steam boilers, electric fan and automatic storage tank-type gas water heater were invented. Chicago began connecting to one of the first comprehensive water and sewer systems. 1912 Chicago sterilized city drinking water and 1920 saw the first siphoned toilet mass produced.

Early 1900’s P&D took advantage of the latest technology and specialized as a leading plumbing, heating and cooling contractor in Will County, IL. We installed the first Joliet air conditioned church in 1939.

1947 Rudy Mahalik joined the firm as an apprentice plumber shortly after serving on a WWII Navy aircraft carrier in the Pacific Theater. In 1950, Rudy was asked to manage the Plumbing Department and in 1960 became a partner. In 1978 the Mahalik family purchased the company and the firm became Poehner, Dillman & Mahalik, Inc.
