Our History

Advantage began in 1968 as a plumbing company called Western Plumbing. The office was located at 121 S. Main Street, Stillwater, OK. Mr. J.W. Huffman was the licensed plumber. Max Koerner, Dale Weathers and J.W. Huffman started the corporation.

Within a few years the need to heating and air conditioning became more important and Paul Marshall was recruited to start the HVAC division of the company. About 5 years after the corporation was chartered, Max Koerner purchased the corporation stock.

In 1983, the company began building a new office located at 1521 E. 6th Ave. The land was owned by Paul Marshall. Max died in 1983 prior to the building being completed. Paul Marshall and Julia Koerner continued to operate the business until 1999.

During 1999 the corporate stock was purchased by Scott and Karen Dean. January 2004, the assets of the corporation were purchased by Regency Enterprises, LLC operated by Dale Sorrell. After re-branding in 2014, Western Mechanical became Advantage Plumbing Heating and Cooling.
