HVAC Services in Chattanooga, TN
NOAA's 1991-2020 climate normals put Chattanooga at 3,029 heating degree days and 1,920 cooling degree days per year. Neither season dominates in Chattanooga. That balance is a big reason heat pumps and dual-fuel systems sell well in Tennessee. Count on roughly 56 nights below 32°F and 58 afternoons past 90°F in a typical year. Snowfall averages about 4 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 45,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
