Top rated local Furnace Repair specialists in Union, SC

Both the city of Union and Union County received their names from the old Union Church that stood a short distance from the Monarch Mill. When it was first founded, the city of Union was known as Unionville; later the name was shortened to Union. The county's first white settlers came from Virginia in 1749. Union County's population grew the fastest between 1762 and the start of the Revolutionary War. Settlers built log cabins and cultivated tobacco, flax, corn and wheat. Union was one of the first towns settled in the area and was untouched during the Civil War because the Broad River flooded and turned Sherman’s troops away from the town.
