NOAA storm reports for Montgomery County show 9 hail days and 43 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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. Montgomery County also had 3 tornado days in that period. In Kettering, 19% 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.

Ohio Permits, Efficiency Rules and Rebates
Ohio 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 Kettering. If a bidder suggests skipping it, move on. Also ask for a Ohio 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
- Multi-zone systems cost more per room, but they run off a single outdoor unit.
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
