Water Heater Replacement in McDonough, explained.
What Drives Replacement Costs in McDonough
Prices vary mainly by unit type: tank gas ($750–$1,900), tank electric ($850–$2,100), tankless ($1,450–$3,300+), and heat pump ($1,700–$3,800). Labor rates reflect local market conditions, and permit fees add a modest amount. Homes with closed systems require an expansion tank, which adds cost. If no drain pan was previously installed, one is not required, but adding one can increase price. The 25C tax credit can offset heat pump costs significantly.
