MAKING IT AFFORDABLE

While residential GHPs cost more upfront than other HVAC systems, more than 20 states offer incentives programs to help offset the cost if the system is part of an energy-efficient home. For example, Oklahoma allows a contractor who is the primary builder of an energy-efficient home substantially completed after December 31, 2005, to claim an income tax credit beginning in 2006. The contractor can take a tax credit for the amount of the eligible expenditures, not to exceed $2,000 for a home that is between 20 percent and 39 percent above the 2003 International Energy Conservation Code, or $4,000 for a home that is 40 percent or more above the code. Find incentive programs in your state through the Database of State Incentives for Renewable Energy (DSIRE).

Technology Highlights

This project included the following PATH-profiled technologies:

• Geothermal Heat Pumps
• Sprayed Foam Insulation
• Windows with High Performance Glass

Many local electric utilities also offer programs to promote GHPs. OG&E, for example, offers financing on energy-efficient heating and cooling equipment. The program includes quickly approved, low-interest loans that require no money down. DSIRE also provides information on utility programs.
