Water heater repair cost by part.
Typical Florence repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Water heater repair in Florence, SC typically costs between $125 and $600 for common repairs, plus a $65–$175 diagnostic fee. With about half of homes built before 1980, many older units may need sediment flushing or element replacement. South Carolina requires a permit for water heater replacements, and an expansion tank is mandatory on closed systems with backflow preventers or check valves.

For energy savings, a heat pump water heater qualifies for a federal 25C tax credit of 30%, up to $2,000.
