Zoning in Lee's Summit: local conditions
Many Lee's Summit homes built from the 1990s through the 2000s put a single thermostat on the main floor, so the system shuts off before upstairs bedrooms cool and runs too long for the walkout basement. A two- or three-zone system lets each level call for heating or cooling on its own.
Zoning works best when the equipment is two-stage or variable-speed, so it's often added when the air conditioner or furnace is replaced. Contractors need a City of Lee's Summit permit for the equipment work.
Utilities: Evergy supplies electricity and Spire supplies natural gas to most homes. Permits: The City of Lee's Summit issues mechanical permits for HVAC replacement and requires licensed contractors.
