Top Rated Geothermal Brands


Trane is one of the largest manufacturers of heating and cooling equipment in the country and so it was natural for them to develop geothermal technology as well. The Trane geothermal lineup is known as Trane EarthWise and there are 3 primary models.

The top of the line is the T2GX/T1GX in 2-stage and single-stage options. It boasts a 29.4 EER which is very efficient and is equipped with a variable-speed blower for indoor comfort. Other Trane EarthWise geothermal heating and cooling units include the T2GY 2-stage geothermal heat pump and the T1GC single-stage model.


Carrier make some of the highest-rated air-based heat pumps on the market and the Carrier geothermal heat pump with 6 different series is just as impressive.

The top of the line is the packaged Carrier GT-PX Series geothermal heating and cooling system with 2-stage operation and up to 31.5 EER. The GT-PX Split Series offers installation versatility and is a good choice for a home addition or the second floor of a large home. The geothermal unit can be in the basement and the air handler or furnace can be installed in a different part of the house.

The GT-PG Series is a single-stage series that is slightly less efficient though more affordable. The Carrier GT-PE geothermal cooling and heating system is a split system that features an outdoor unit and an indoor air handler or furnace, making it a good choice for homes without a basement. The Carrier GT-PW High Temp and standard GT-PW geothermal units are hydronic systems, also called water to water system. This means that the heat collected by the water in the loop is transferred between water in a radiant heat system.

Climate Master

Climate Master heat pumps might be the top-rated geothermal heating and cooling systems currently available. Climate Master keeps it simple with just one geothermal system, the Tranquility Series heat pump system.

The Climate Master Tranquility 20 TS Series is a single-stage, single-speed model though a variable-speed blower is an option. The Tranquility 27 TT Series from Climate Master is 2-stage with a variable-speed blower, providing maximum comfort and efficiency. They are standard geo thermal heat pumps but water to water operation is an option on both series. Additional options include whole-house dehumidification and downflow configuration.
