Jeffersonville Weather and HVAC Load
NOAA's 1991-2020 climate normals put Jeffersonville at 4,140 heating degree days and 1,642 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Jeffersonville put in far more hours than the air conditioner. A normal year brings 77 nights at or below freezing and 46 days over 90°F. Snowfall averages about 4 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 50,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Indiana Permits, Efficiency Rules and Rebates
Indiana 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. Equipment replacements in Jeffersonville generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Indiana license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs.
