Kokomo Weather and HVAC Load
NOAA's 1991-2020 climate normals put Kokomo at 6,059 heating degree days and 833 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Kokomo put in far more hours than the air conditioner. On average, Kokomo gets 131 freezing nights and 12 days above 90°F per year. Snowfall averages about 34 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 65,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Howard County had 4 hail days and 21 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.85 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. In Kokomo, 19.1% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk. Mention it when you call, since many companies put those calls first.

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 Kokomo 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.
Before You Hire
- 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.
- A combi boiler frees up space and replaces your water heater.
