Kansas HVAC Load Calculation Guide
Kansas is a balanced heating-cooling state at the epicenter of Tornado Alley — a 100°F summer design temperature and 3°F winter design temperature create near-equal seasonal loads, while severe weather events make equipment durability a critical design consideration.

Kansas HVAC FAQ
The ASHRAE winter design temperature for Kansas is 3°F and the summer design temperature is 100°F. These values are used for heating and cooling load calculations per ACCA Manual J methodology.
Kansas spans 4A, 4B, 5A per ASHRAE Standard 169-2021. This classification determines minimum insulation requirements, energy code compliance path, and HVAC equipment sizing parameters.
The required HVAC size depends on home square footage, insulation levels, window area, and orientation. For a typical 2,000 sq ft home in Kansas, use our heating load calculator with the local design temperature of 3°F (winter) or 100°F (summer) for a preliminary estimate.
No statewide HVAC license is required in Kansas. However, local municipalities may have their own permit and licensing requirements. Always check with your local building department.
Kansas follows the Kansas Energy Code (2018 IECC, statewide adoption 2019). This code sets minimum requirements for HVAC equipment efficiency, duct insulation, envelope insulation, and ventilation.
