Greenwood Weather and HVAC Load
In a normal year, Greenwood racks up 5,703 heating and 946 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Greenwood put in far more hours than the air conditioner. Count on roughly 120 nights below 32°F and 13 afternoons past 90°F in a typical year. Snowfall averages about 17 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 60,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Greenwood Housing Stock
Census figures put the median build year in Greenwood at 1995, so a typical house here has about 31 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Greenwood has roughly 16,000 owner-occupied homes, or 60.9% of households. With a median household income of $78,765 and a median home value of $248,700, local labor rates come out near the national middle in our model.
NOAA storm reports for Johnson County show 4 hail days and 18 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 2 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Johnson County also had 3 tornado days in that period.

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 Greenwood 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. Check your electric and gas utility's rebate page before you pick equipment.
