The Cleveland market
The City of Cleveland's Department of Building and Housing requires residential permits for plumbing and HVAC work, and its permits page gives replacing a furnace as an example. For 1-3 family homes, each central heating or air conditioning system is $50, plumbing fixtures and appliances (including hot water heating devices) are $8 each, and any HVAC or plumbing permit has a $50 minimum. Contractors must hold a State of Ohio license and register with the City. An owner who personally performs the work can file instead, but the homeowner affidavit must be notarized. Inspections need at least 24 hours' notice, and homeowners must be present. Suburbs such as Lakewood and Parma run their own departments. Statewide, EIA's 2020 survey found 64% of Ohio homes heat with gas and 77% use a furnace.
A gas tankless conversion means a new vent and often a larger gas line, so it costs more than a tank swap up front. Leave gas line resizing and vent changes to the plumber. Ask the contractor which permits the conversion needs and include each one in your comparison. Ask what flow rate the unit delivers with winter water temperatures, and whether the quote includes isolation valves so the heat exchanger can be descaled later.
