Comfort-Aire’s GeoMax2® HTS Series split system geothermal heat pumps feature two-stage operation that saves energy by shifting between part load and full load, automatically adjusting to optimize comfort. It does this by running at 67 percent capacity most of the time, maintaining a constant temperature and humidity level. When there’s a greater demand for conditioning, such as during weather extremes, the unit instantly shifts to 100 percent capacity. Efficiency is enhanced by a multi-stage, unloading scroll compressor.
