What does gas water heater repair typically cost?
Cost depends on the specific part or issue involved — a thermocouple replacement is relatively inexpensive, while a gas valve or full tank issue costs more. Pricing is discussed directly with the technician after diagnosis.
How long does a typical gas water heater last?
Most tank-style units last around 8 to 12 years depending on water quality and maintenance. Tankless units tend to last longer with proper upkeep. A technician can assess your specific unit's condition.
Should I repair or replace my gas water heater?
It generally depends on the unit's age and what's failed. A control valve or thermocouple issue on a newer tank is usually worth repairing; a rusting tank near the end of its typical service life is often better replaced. A technician can advise after inspecting it.
