We're local. King's Frankfort team handles furnace and AC repair, plumbing and new systems for Frankfort homes and businesses, 24/7.
Frankfort is a village of about 20,300, mostly in Will County. King has served it since 1968, and our Frankfort location at 101 Ontario Street keeps technicians and plumbers close to your home or business.
One team covers heating, cooling and plumbing, so the same company that tunes up your furnace can replace your water heater or find a hidden leak. We repair and service all makes and models.

Frankfort grew from about 1,100 people in 1960 to 20,296 in 2020. Past the historic downtown and the Old Plank Road Trail, most homes date from the 1990s and 2000s, and the water comes from wells.
Frankfort's water comes from wells in a shallow aquifer, not Lake Michigan, and the Village recommends a softener setting of 25 grains per gallon. Water that hard leaves scale in tank and tankless water heaters. A water softener extends the life of either.
More than half of Frankfort's homes were built between 1990 and 2009. Central air typically lasts 12 to 15 years, so equipment installed with those houses is at or past replacement age. Start with a free in-home estimate on a new AC or furnace.
The historic downtown, home to the Frankfort Grainery and Breidert Green, is also a business district. We handle commercial HVAC, plumbing and refrigeration from the same Ontario Street location.
With a location right on Ontario Street, King is part of the Frankfort community. You'll see us around town on service calls and at the fall festival parade.
