Water heater installation cost by job.
Installed-labor pricing for McDonough, adjusted for local rates. Relocations and gas-line upgrades add to the base.
In McDonough, Georgia, water heater installation costs typically range from $750 to $1,700 for a standard tank model and $1,700 to $4,300+ for a tankless unit, with additional costs for new gas lines ($275–$950). Most homes were built around 2005, so many original units are nearing the end of their lifespan. The local climate is humid subtropical with moderate winter inlet water temperatures, making heat-pump water heaters a strong fit due to their efficiency. Georgia requires permits for water heater installations, and expansion tanks are needed on closed systems. The federal 25C tax credit offers 30% back (up to $2,000) for heat-pump models, reducing overall cost.

What Affects Installation Cost in McDonough
Labor rates reflect the local median income of $77,804, and permit fees add a modest amount. Tankless units cost more due to complex venting and gas line upgrades. Adding a new gas line ($275–$950) or an expansion tank (required on closed systems) increases the total. The age of your home (median built 2005) may require code updates, such as bringing the unit up to IPC standards with Georgia amendments. Choosing a heat-pump water heater qualifies for the federal tax credit, which can offset the higher upfront cost.
