Sizing a furnace for this county starts with what the burner and heat exchanger are actually asked to carry each year. Homes in Morris County, KS run heat about seven months a year, from October through April. A system that comes in undersized cycles harder to keep up, and the ignition system and heat exchanger accumulate wear at a rate a correctly sized unit would not. Contractors pricing a new install here factor that load into equipment selection before anything else, because a marginal fit shows up in component failure well before the furnace reaches the end of a normal service life.

Ductwork laid when a house was built carries the dimensions, the routing, and the return-air assumptions of whatever heating system was in it at the time. Half the homes in Morris County, Kansas were built in 1960 or earlier (2020-2024 ACS 5-year). That gap between what the ducts were built for and what a new furnace actually requires is where a contractor spends the most time during an installation here, measuring airflow, checking static pressure, and deciding which runs need to be altered before the new unit can do its job. The electrical side follows the same logic: service panels in houses of this vintage were sized for a different load than a modern furnace draws. The ductwork and the panel together determine the scope before the equipment is even ordered.
What Gets Installed With a New Furnace

The furnace itself sits in a mechanical room, basement, or utility closet and is the unit a homeowner is most likely to recognize. Inside that cabinet, a heat exchanger and a burner assembly do the core work. The blower motor, housed in the lower section of the same cabinet, pushes conditioned air out into the home.
The flue pipe runs from the furnace to an exterior wall or roofline and carries combustion gases out of the house. Alongside it, the contractor installs a new filter housing if the existing one does not fit the replacement unit, and connects the thermostat wiring so the controls match the new equipment.
The drawing shows a typical layout, and a licensed contractor determines exactly what applies to your home.
