The Oklahoma City market
Oklahoma City's Development Center answers the question directly: replacing a water heater requires a plumbing permit. Heating and air work falls under the general rule that permits are needed to construct, alter or repair, issued before work begins. The city is strict about who can pull them: electrical, plumbing, mechanical and heat-and-air permits may only be issued to contractors licensed by the State of Oklahoma and registered with the city, and no homeowner route is described. Each permit comes with a required inspections list. Fees were not confirmed, so check the city's fee schedule. Suburbs like Edmond, Norman and Moore have their own departments. Statewide, EIA's 2020 survey found 52% of Oklahoma homes heat with natural gas and 39% with electricity, 69% use a furnace and 83% have central air.
In Oklahoma City, a furnace often shares its cabinet with the AC coil, so ask whether the coil is being reused. Ask each contractor to list the furnace's AFUE and the venting plan. A high-efficiency model drains condensate and vents through plastic pipe, so ask where both will run. With electric heat common statewide, ask for a heat pump price alongside the furnace so you can compare.
