Comfort Aire's two stage models are among the most efficient heating and cooling systems available today, with EERs as high as 29.1 and COPS as high as 4.8.

The two-stage design allows the unit to run at 67% capacity most the time to maintain a consistent temperature and humidity level. When there's a demand for greater heating/cooling (such as during temperature extremes), the unit automatically and instantly changes to 100% capacity. This part load/full load capacity significantly lowers annual operating costs while increasing comfort.

In addition to the full load/part load operation, a variable speed blower motor (on the HTV Series) adds to comfort and efficiency with a multitude of operational modes. The blower motor automatically adapts to all applications.

The GeoMax2 system uses environmentally friendly R-410A.

A hot water generator with built-in pump and CuNi coil are standard features that add value and efficiency.
