No hot water, temperature swings, a leaking tank, unusual sounds, and repeated faults can lead to different water-heater conversations. Start with the equipment details and the actual symptom.
Repair may focus on a specific confirmed component or connection. Replacement planning adds equipment fit, fuel type, capacity, connections, access, removal, installation requirements, and current city questions.
Compare the scope rather than a label: what was inspected, what is being repaired or replaced, whether the existing setup is compatible, who handles permit questions, and what is included in removal, connection, testing, and cleanup.
Water-heater repair and water-heater installation are separate service paths; use the page that matches the decision you are actually making.
