Repair time depends on what failed and the type of system you have. Common repairs like replacing a thermostat, heating element, or some gas ignition components can often be completed in a single visit. Tankless repairs may take longer depending on diagnostics and parts. If there’s a leak or a more complex failure, the best path might be replacement instead of repair.
