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.

Gas heats water in 57% of Ohio homes, so a gas tank is the usual like-for-like quote in Cincinnati. Ask whether the new tank vents into the same flue as the furnace and whether that flue still suits both appliances. A tank taller or wider than the old one may need the gas and water lines reworked. Ask whether an expansion tank, a new shutoff valve and haul-away are in the price. Small items like these explain much of the spread between bids.
