Dublin Weather and HVAC Load
NOAA's 1991-2020 climate normals put Dublin at 5,486 heating degree days and 918 cooling degree days per year. Heating is the bigger job here, and furnaces and heat pumps in Dublin put in far more hours than the air conditioner. On average, Dublin gets 112 freezing nights and 17 days above 90°F per year. Snowfall averages about 24 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 60,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Dublin Housing Stock
Half the homes in Dublin were built before 1996 (Census ACS median), so the typical house is about 30 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 77.1% of occupied homes, roughly 14,000 households. With a median household income of $155,282 and a median home value of $514,900, local labor rates come out above the national middle in our model.
NOAA storm reports for Franklin County show 16 hail days and 41 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. Franklin County also had 2 tornado days in that period.

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. Equipment replacements in Dublin generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Ohio 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
