The GT-PG series offers exceptional quality, quiet performance and year round comfort. Optional upgrades include a variable-speed motor and supplemental hot water generation. A single-stage scroll compressor, combined with a single- or (optional) variable-speed motor, tin plated coil, microprocessor control and quiet operation make this a great choice.
Perhaps best of all is the Federal tax credits still available on geothermal systems. You can revel in getting a tax credit of up to 30% of your installed cost of a geothermal system.
