Geothermal Advantage

 Carrier geothermal systems provide several good options for efficient indoor heating and cooling by tapping into the earth to capture its renewable energy. Here’s how it works:  The earth absorbs energy from the sun and stores it in the ground. A geothermal system extracts that energy for home heating during the winter. For cooling, the system removes heat from the home and places it into the cooler earth. The transfer of heat energy is done through a series of pipe either buried in the ground, sunk in a pond, or by using well water.

Why Choose Geothermal?

Savings

 Geothermal systems can offer lower operating costs compared to ordinary forced air heating and cooling systems. Those savings can be as high as 70% in annual heating and cooling costs 

Comfort

 These systems can provide even temperatures  throughout the home year round, with excellent  dehumidification during cooling.

Reliability

 Geothermal units are known for durability and can operate for years with little maintenance. In addition,  ordinary heat pumps and air conditioners are located outdoors and are subject to wear and tear caused b  extreme temperatures, rain, snow, hail, and pollutio  which can potentially reduce their life expectancy.  Because geothermal units are located indoors, the  can last 20+ years.

Quiet Operation

 Unlike ordinary air conditioners and heat  pumps, no outdoor unit is required. Carrier geothermal  units use heavy-duty, fully-insulated cabinets for quiet  operation. Quiet, soft starting variable-speed blowers are  used in many models 

Hot Water

 Excess heat from system operation can be  used to supplement the home’s water heater. 

Geothermal Loop Options

Horizontal Loops

Horizontal Loops

Horizontal Loops

Used on larger lots.  Installed using a backhoe or trencher.

Vertical Loops

Horizontal Loops

Horizontal Loops

 Used where land area is limited or soil conditions prohibit horizontal  loops.  Installed using a drilling rig.

Pond Loop

Pond Loop

Pond Loop

 Coils of pipe are fabricated and sunk to the bottom of the pond.

Open Loop

Pond Loop

Pond Loop

 Well water from an existing well  can be used, then discharged  into a drainage ditch or pond.

Geothermal Frequently Asked Questions

Please reach us at jrcombs@combsheatingandcooling.com if you cannot find an answer to your question.

 Actual efficiencies will depend on a number of factors  but, generally speaking, a geothermal heat pump can be  between two to five times more efficient at producing heat  than a gas, propane or oil furnace (based on the amount of  energy consumed to produce a given amount of heat). For  cooling, a geothermal system (30.0 EER) can be up to  three times more efficient than an air source air conditioner  (10.0 EER). 


 Geothermal heat pumps use the ground temperature as a  “source” for heat energy to help warm your home, and use  the ground as a heat “sink” during cooling. The earth acts  as a giant energy battery, providing an endless, renewable  source for heating and cooling comfort. Standard heat  pumps use outdoor air for heating and cooling. Because  the ground temperature is much more moderate and stable  than air temperatures, geothermal system operation is  much more energy efficient, especially at extreme outdoor  temperatures. 


 It depends on several factors. Homes on larger lots usually  have horizontal loops installed. Smaller lots may require a  vertical loop. A nearby pond can also be used. If you have  a well water system, that may be an option. Your Carrier  dealer is trained to determine which loop design is most  appropriate for your home. Regardless of the loop system  selected, the operating costs are all about the same. 


 The smallest closed loop design, the vertical loop, may  require a space of only 15x15 feet, or a line of 3x45 feet,  located at least 10 feet away from the home, and 10 feet  from property lines. Horizontal loops require considerably more space.


 No. Antifreeze in the loop fluid eliminates any concerns about freezing .


 Yes.  Some homeowners like the benefits of both  technologies. In this case, a geothermal “split” unit  (compressor only) is connected to a furnace and cooling  coil. The geothermal unit will perform all the cooling  and some of the heating. During the coldest  days, the system can switch over to  furnace operation to provide the warmest  air temperatures and maximum capacity.
