NOAA's 1991-2020 climate normals put Hattiesburg at 1,922 heating degree days and 2,439 cooling degree days per year. Neither season dominates in Hattiesburg. That balance is a big reason heat pumps and dual-fuel systems sell well in Mississippi. A normal year brings 32 nights at or below freezing and 85 days over 90°F. For a 2,000 sq ft house, this climate points to a heating load somewhere near 35,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
