Kansas City Weather and HVAC Load
NOAA's 1991-2020 climate normals put Kansas City at 4,613 heating degree days and 1,707 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Kansas City put in far more hours than the air conditioner. A normal year brings 93 nights at or below freezing and 47 days over 90°F. Snowfall averages about 11 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Jackson County had 15 hail days and 36 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across.

Jackson County also had 4 tornado days in that period.

Missouri Permits, Efficiency Rules and Rebates
Missouri falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Plan on a mechanical permit for most replacements in Kansas City; the contractor normally pulls it. Before you sign, ask each bidder for their Missouri license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- Ask your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- For a steam system, hire a contractor who works on steam regularly.
