Carrier Indoor & Outdoor Split Geothermal Heat Pumps - Rev.: 08/10/05

The GT-S does not need to be located outside. 
It can be placed in garages, carports, basements, 
crawl spaces, etc. This may be important to some 
homeowners who may be very concerned about 
outdoor aesthetics. They also can utilize ground 
water if placed in an appropriate indoor location. 
Noise is not a problem as the GT-S is extremely 
quiet (the box is sealed and insulated). The GT-S also 
has excellent heating and latent cooling capacities 
compared with competitive high effi ciency geothermal 
units. In many cases a GT-S produces the heating 

output of one size larger competitor unit. And the 
GT-S is likely to be the highest EER per dollar cost 
unit available in the geothermal industry today.

The goal for the GT-S Series is based upon 
application fl exibility, effi ciency, reliability and a solid 
state microprocessor compressor control, producing 
a reliable, simple product both easy to service and 
install. Its effi ciency and application fl exibility make it 
the “Paradigm” of geothermal heat pumps.
