Frank L. Haldeman began repairing hand operated well pumps, installing automatic jet pumps, and installing “modern” indoor plumbing and heating systems in 1939. In 1949, he established F.L. Haldeman & Sons Plumbing, Heating and Cooling with his three sons, Lloyd, Ed, and Jay, and son-in-law, John Heisey. The company incorporated in 1965 and continued until 1989, when the last of the Haldeman family left the corporation. The company was then purchased by an employee.

In 1982, Mark Haldeman, Lloyd’s son and Frank’s grandson, opened Mark Haldeman Mechanical Service Company, a plumbing, heating, cooling and water conditioning business. The company incorporated in 1995 and became Haldeman Mechanical, Inc. In 2001, Haldeman Mechanical purchased F.L. Haldeman and Sons, Inc. The company now operates from the original F.L. Haldeman and Sons location at 1148 Old Line Road in Manheim.

Through three generations, the company has maintained its commitment to residential and light commercial services. When you hire Haldeman Mechanical, you are hiring a name that has come to be respected in the service industry over the past 67 years.
