Repair or Replace Your Water Heater: How to Decide
This is the question we get asked more than any other, and the honest answer depends on three things: the age of your unit, what exactly is wrong, and how much the repair actually costs compared to a new one.
The Age Rule of Thumb
Under seven years old with a single symptom, repair almost always makes sense. Past eight to ten years, especially in San Antonio where hard water shortens tank life to 6 to 8 years, replacement usually wins financially even if the current repair looks cheap, because another failure is likely close behind.
What Is Actually Wrong Matters More Than Age Alone
A failed thermostat or heating element on an otherwise healthy five year old tank is a clear repair. A leak coming from the tank body itself, at any age, is not repairable, that is corrosion from the inside and the tank needs replacing regardless of how new it looks from the outside.
The Half Cost Rule
If a repair quote starts approaching half the price of full replacement, roughly $600 to $1,000 depending on your area, replacement usually makes more sense long term, especially on a unit already past its expected lifespan. We tell customers this even when it means less repair work for us.
A Quick Checklist
- Unit under 7 years, single symptom: repair
- Unit over 8 to 10 years, any symptom: lean toward replace
- Tank body itself leaking: always replace
- Repair quote over half of replacement cost: replace
- Multiple failures in the past year: replace
