Furnace Repair in Franklin, WI

Franklin's rapid residential expansion in the 1990s and 2000s means most homes in the city were built with modern forced-air heating systems — two-stage and modulating furnaces, PVC flue systems, and sealed combustion air intakes are standard in the subdivisions that grew south of Ryan Road and near the Ballpark Commons development and Northwestern Mutual campus corridor.

But "newer" doesn't mean "maintenance-free." The furnaces installed in Franklin's 1990s construction wave are now 25 or more years old — beyond the typical reliable service life for most residential equipment. Two-stage furnaces from this era are experiencing inducer motor failures, cracked heat exchangers from years of cycling, failed electronic ignitors, and deteriorating pressure switch hoses. These are all repairable individually, but for systems this age, the economics of continued repair versus full replacement require honest assessment.

The open land on Franklin's western and southern edges — where farmland still meets residential development along W. Rawson Avenue and S. 27th Street — means seasonal pollen loads can be heavy, and furnace filters need regular replacement to prevent the restricted airflow that causes high-limit switch trips and heat exchanger stress. A homeowner who lets the filter go unchecked for a full heating season is inviting the kind of heat exchanger damage that ends with a premature replacement.

Winter temperatures in Milwaukee's southern suburbs can fall below -10 degrees Fahrenheit during January cold snaps, and Franklin's relatively open landscape provides less urban heat island moderation than denser communities closer to Milwaukee. When a furnace fails in those conditions, emergency response is not optional.

My Franklin home was built in 1997 and still has the original furnace. Should I be worried?

A furnace nearly 30 years old is operating well past its design life. Even if it's still running, efficiency has declined significantly and critical components like the heat exchanger may be approaching failure. Burkhardt can inspect the heat exchanger and assess whether continued repair is prudent or whether replacement is the safer, more economical choice.

My Franklin furnace trips the high-limit switch and shuts off. What causes this?

The high-limit switch protects the heat exchanger from overheating damage. It trips when airflow is restricted — usually from a clogged filter, closed supply registers, or a failing blower motor. Check and replace your filter first. If the problem persists, call Burkhardt at 414-206-3049 to diagnose the root cause.
