Temperatures remain relatively constant year-round.  In Northern Climates the temperature is about 45 degrees Fahrenheit and in Southern Climates about 70 degrees Fahrenheit.  The earth absorbs about 47% of the suns solar energy and stores it.  A geothermal system, which consists of an indoor unit and a buried earth loop, capitalizes on the earth’s constant temperatures.

2. What makes a geothermal system different from conventional systems?
A geothermal system utilizes the energy from the sun, which is stored in the earth, to heat and cool homes and buildings. Typically, electric power is used only to operate the unit’s fan, compressor and pump. So, unlike conventional systems, geothermal systems do not burn fossil fuel to generate heat–they simply transfer heat to and from the earth.

3. How efficient is a geothermal system?
A geothermal system is more than three times as efficient as the most efficient conventional system. Because geothermal systems do not burn combustible fuel to make heat, they provide three to four units of energy for every one unit used to power the system.

4. What does geothermal mean to the environment?
Because geothermal systems work with nature, not against it, they minimize the threats of acid rain, air pollution and the greenhouse effect. An environmentally friendly fluid is used in the closed, continuous loop.

5. Do geothermal systems require much maintenance?
No. In fact, geothermal systems are practically maintenance free. When installed properly, the buried loop will last for generations. And the other half of the operation–the unit’s fan, compressor and pump–is housed indoors, protected from the harsh weather conditions. Usually, periodic checks and filter changes are the only required maintenance.

6. How much money can I save with a Geothermal System in my home?
In a technology defined by numbers, here’s a fact that everyone will understand: You’ll pay several thousand more up front, but in many cases, the payback can come in as little as 5 to 7 years.  And once the system is paid off, the annual return on investment can approach 15-20%.  Add impressive durability and less-intrusive trenching methods and the scales begin to tip, at least in the new home market.  But, Geothermal systems can also be installed in existing homes as well.  It will also increase the value of your home.  Many people comment on how “clean” geothermal heat & cooling is for their home.  There is virtually no dust since fossil fuels are not involved.  It is much healthier for you and the environment.
