North end

The older north end, closer to I-35 and Shawnee Mission Parkway, has 1950s and 1960s ranches and split-levels. Those usually have thin attics, bare rim joists and walls with slumped or missing batts. A typical plan: seal the attic floor, blow in to depth, foam the rim joist and dense-pack any empty walls.

South end

South of I-435, homes are larger and newer, with bonus rooms over garages, vaulted ceilings and ductwork in the attic. The usual complaints are a hot upstairs in summer and a cold bonus room in winter. Sealing and insulating the attic, the bonus room floor and the kneewalls fixes most of it.

Weather

Average July highs reach about 89F and January lows about 20F, with records of 114F and -22F, and about 17.3 inches of snow in an average year. The city sits in a transition zone between climate types, with hot, humid summers and cold, dry winters. OpenEI places Johnson County in Climate Zone 4A.

About 60.5% of Overland Park homes are owner-occupied, and 83.9% of residents lived in the same house a year earlier, per Census estimates. Long-term owners usually get the most out of air sealing and insulation.

Evergy rebate

If Evergy supplies your electricity, its 2025 Kansas chart lists rebates for air sealing, R-38 ceiling insulation and rim joist insulation installed on or after June 1, 2024, through December 31, 2027.

Ductwork in the attic

Many Overland Park homes, especially two-stories and ranches built from the 1970s on, have furnace ductwork or an air handler in the attic. In July, that attic can be much hotter than outside. Leaks at duct joints and boots pull hot attic air into the system and push cooled air into the attic. We seal the duct joints and boots we can reach while we are up there, and tell you about anything that needs an HVAC contractor.
