Furnace replacement in Kansas City, Missouri
Most Kansas City, Missouri furnace replacements are in basements of older homes, where the key decision is venting: keep an 80% furnace in the chimney, or move to a 96% model with PVC venting and a liner for the water heater.

Many older Kansas City homes, especially the brick and frame houses in Brookside, Waldo and Overland Park's first-ring suburbs, have basement furnaces that vent into a masonry chimney. Moving to a high-efficiency furnace means new PVC venting and often a chimney liner for the water heater left behind.
In a climate with 4,700-plus heating degree days a year, a condensing furnace pays back faster than it would farther south, but the venting work has to be planned.

Furnace replacement in Kansas City: local conditions
Brookside, Waldo and Midtown homes commonly vent the furnace and water heater into a shared masonry chimney. When a high-efficiency furnace moves to PVC venting, the water heater is left alone in a chimney built for much more heat, which can cause poor draft and condensation damage. Contractors usually add a chimney liner or change the water heater venting at the same time.
Older homes also tend to have small return air paths. A new furnace with a variable-speed blower performs best when returns are improved, so ask the contractor to measure static pressure. Replacements inside city limits need a Kansas City, Missouri mechanical permit.
Utilities: Evergy supplies electricity and Spire supplies natural gas to most homes. Permits: The City of Kansas City, Missouri, requires licensed mechanical contractors and permits for furnace and AC replacement and new ductwork.

Frequently asked questions
Do I need a chimney liner with a new furnace in Kansas City?
Often, if you switch to a high-efficiency furnace and the water heater stays in the chimney. The contractor should check draft and size.
How long does a furnace last?
Typically 15 to 20 years with maintenance. Cracked heat exchangers and failing inducer motors are common end-of-life signs.
Is a 96% furnace worth it in Kansas City?
Usually, given the long heating season, unless the venting changes would be unusually expensive. The contractor should show both options.
