The Cincinnati market

Cincinnati's Department of Buildings & Inspections requires permits for heating, ventilating and air conditioning equipment "for installation or replacement," and replacement HVAC permits can be filed online. In Residential Code of Ohio projects, replacing equipment costs $118 for the first unit plus $48 for each additional unit, before surcharges: 5% planning, 3% technology, 1% training, 1% financial recovery, and a 1% state surcharge for 1-3 family homes. Inspections need at least 24 hours' notice through Building Construction Inspections (352-3267). Plumbing permits cover "all replacement fixtures," but no city page names water heaters, so confirm. Northern Kentucky and Indiana suburbs have separate departments. Statewide, EIA's 2020 survey found 77% of Ohio homes heat with a furnace, 64% use natural gas and 74% have central air.

Many Cincinnati homes pair central air with a gas furnace, and the AC coil sits on that furnace. When the condenser fails, ask whether the coil is old enough to replace at the same time, since a mismatched pair can underperform. When the furnace is also near the end of its life, ask what replacing both at once would cost. Get the tonnage, SEER2 rating and warranty terms written on each quote so the bids line up.
