📅 The Age Rule: When to Stop Repairing

The average water heater lifespan in Fort Worth is 8–12 years for tank units and 15–20 years for tankless. In Fort Worth's water conditions, mineral buildup can accelerate wear. Our rule: if your Fort Worth water heater is under 6 years old and the repair is under $400, repair. Between 6–10 years, compare repair cost to 50% of replacement cost. Over 10 years in Fort Worth conditions — replace. Simple math beats emotional attachment to aging equipment.
