Kent Oil Company was originally founded in 1936 by Walter and Mildred Kent. Volume was smaller at this time and delivered by hand. As a result, a friendly relationship was common with most customers.

In the 1950's, Walter 's oldest son Jerry joined the operation to help out with growing business demands. Jerry married in 1953 and brought his wife Anne into the business to help as well.

After Walter 's retirement, Jerry and Anne continued as Amoco Agents until jobberships were offered in 1976. In 1976, Jerry purchased the jobbership from Amoco and became an Independent Amoco distributor. Immediately following, the current bulk plant and office were constructed.

In 1981, Jerry 's son John joined the Company as a transport driver and took over transportation of liquid petroleum. In 1988, Jerry 's son-in-law Jeff Hynes joined the business and he worked in all areas of operation.

As the demand for propane became apparent, a new propane plant was added in 1992. This new product gave an opportunity to maintain customer base when movement toward propane furnace placement was obvious.

With continued growth in the business, it became necessary to add more staff to handle the demands. In 1994, John 's wife Denise joined the business becoming extensively involved in the internal office responsibilities.

In 1996, Jerry and Anne sold the business to John Kent and Jeff Hynes and retired a few months later.

In June of 1999, Frost Heating & Cooling was acquired. A new building was soon built at the Kent Oil & Propane location to provide office and HVAC equipment storage. Frost Heating & Cooling continues to provide service and new installations to a four county Mid-Michigan area.
