In a normal year, Brookings racks up 8,378 heating and 523 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here, and furnaces and heat pumps in Brookings put in far more hours than the air conditioner. On average, Brookings gets 177 freezing nights and 8 days above 90°F per year. Snowfall averages about 36 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 80,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Brookings Housing Stock
Census figures put the median build year in Brookings at 1987, so a typical house here has about 39 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. About 4,300 households here own their home, 48.5% of the occupied total. Homes here have a median value of $243,600 and households a median income of $61,979. Those two numbers drive the labor adjustment in our estimate.
Brookings County had 13 hail days and 16 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Brookings County also had 2 tornado days in that period.

South Dakota Permits, Efficiency Rules and Rebates
South Dakota 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. Expect the contractor to pull a mechanical permit for a replacement job in Brookings. If a bidder suggests skipping it, move on. Also ask for a South Dakota 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
- For a steam system, hire a contractor who works on steam regularly.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- Ask your gas or oil company about rebates on condensing boilers.
