The repair-vs-replace rule for water heaters

Replace any water heater with a leaking tank — that is not repairable. Elements, thermostats, and thermocouples are worth fixing on a unit under 10 years old; past 12, plan the replacement.

Rules of thumb are starting points. For a precise answer based on your unit's age, the actual quote, and your local labor rate, use the calculator.

Frequently asked questions

How long should a water heater last?
A mid-range water heater typically lasts 9–12 yrs. Budget models run shorter and premium units longer — see the lifespan table above for the full tier breakdown drawn from NAHB and InterNACHI data.
Is it worth repairing a water heater?
It depends on age and the specific part. A typical major water heater repair runs about $180–$550 installed. If that is more than half the price of a comparable new unit and the appliance is past two-thirds of its expected life, replacement usually wins.
What water heater repairs can I do myself?
The parts marked DIY-friendly above — typically thermostats, elements, seals, and pumps — are within reach for a careful owner with basic tools. Anything tagged gas, refrigerant, or high-voltage should go to a licensed professional.
Does my location change the repair cost?
Yes. Labor is the largest share of most repair bills, and technician wages vary by metro. The same job can differ 25% or more between markets — check your local rate on the labor-cost pages, then run the calculator with your actual quote.
