What affects water heater replacement cost in Waukegan?
The price depends on the unit type (gas tank, electric tank, tankless, or heat pump), labor rates, and any necessary upgrades like an expansion tank or venting modifications. Older homes may require additional work to meet current code, such as updating gas lines or electrical connections. Permits add a fee, and choosing a more efficient model like a heat pump can qualify for the federal 25C tax credit (30% up to $2,000), offsetting the higher upfront cost.
