Fire and Ice Geothermal LLC has been around since 1989 and Ray Bayliff, the owner of the Woodward, Okla., geothermal drilling company, says the last year and a half has been slower than usual. The business, which employs a staff of 14, depends heavily on demand for geothermal heat pump (GHP) installation, which makes up 100 percent of business. For this reason, the end of the federal Investment Tax Credit and Residential Energy Efficiency Property Credit for GHP installation is anything but good.
