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. The AC still runs every summer, but it works far fewer hours than the furnace does. On average, Kokomo gets 131 freezing nights and 12 days above 90°F per year. Snowfall averages about 34 inches. On the cooling side, a 2,000 sq ft house here usually needs around 2.5 tons. A tight, well-insulated house may get by with half a ton less.

Kokomo Housing Stock
Half the homes in Kokomo were built before 1966 (Census ACS median), so the typical house is about 60 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. Kokomo has roughly 17,000 owner-occupied homes, or 65% of households. Homes here have a median value of $126,500 and households a median income of $54,195. Those two numbers drive the labor adjustment in our estimate.
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.
When It Makes Sense
- Summer electric bills keep going up
- It has had more than one refrigerant leak
- The AC is 12 to 15 years old or more
- The house can't reach the thermostat setting on hot afternoons
What Moves the Price
- SEER2 rating and whether the compressor is single-stage or variable-speed
- Electrical work such as a new disconnect, breaker or wiring
- Tonnage, based on house size and local climate
- Whether the coil and line set also need replacing
- The pad, permit and refrigerant (R-410A or the newer R-454B)
We lowered the national figures about 21% for Kokomo using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.
What the Quote Should Cover
- Startup, an airflow check and warranty registration
- Removing the old condenser and coil
- The new condenser, coil and, if needed, line set
- The electrical disconnect and wiring
- Refrigerant charge and a leak test
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 Manual J calculation. "Same size as the old one" isn't sizing.
- Ask what federal, state or utility incentives apply to the model you're quoted.
- Buy the condenser and coil as a matched set, or you may void the manufacturer warranty.
