Geothermal Incentives Get Help Funding Your WaterFurnace Installation Installing a WaterFurnace geothermal system can dramatically reduce the cost of heating, cooling, and providing domestic hot water for your home. If you're anything like your Hattiesburg neighbors, though, it's getting past the initial installation cost that's difficult. Don't worry. There's help. It comes in the form of various federal, state, and local financial incentives. The most obvious – and wonderfully welcome! – incentive right now is the return of the 30% federal geothermal tax credit. Read all about it in this blog and in our special flier, Understanding the Federal Tax Incentives for Geothermal Heat Pumps.
