Columbus Housing Stock
Half the homes in Columbus were built before 1981 (Census ACS median), so the typical house is about 45 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. Owners live in 61.2% of occupied homes, roughly 13,000 households. The median home value is $231,000, and median household income is $76,856. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 6 hail days and 15 days with damaging thunderstorm winds in Bartholomew County. The largest hail reported was 1.25 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.

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 Columbus 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
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Rinse the indoor filters once a month during heavy use.
