Advantages of Geothermal Heating & Cooling

Lower Operating Costs:

A geothermal heat pump will immediately save you 30-70% on heating costs and 40-75% on cooling costs over conventional heating and cooling systems. In dollar terms, for every $1 you pay in electricity you get $4 of heat because geothermal systems have a 400% efficiency rating. 4 units of energy are delivered for every 1 unit of electrical energy. This doesn’t bend the laws of physics; a geothermal system doesn’t burn fuel to create warmth; it simply moves existing heat from one place to another. This renewable energy uses the earth’s natural heat to heat and cool your home.

Environmentally Friendly:

The EPA and the U.S. Department of Energy recognize geothermal systems as the most environmentally friendly way to heat and cool a home. Geothermal does not emit carbon dioxide, carbon monoxide, or other greenhouse gases that contribute to air pollution. Low demand from geothermal systems helps reduce peak grid demand and the need for more electric generating plants. Geothermal systems minimize ozone destruction by using factory-sealed refrigeration systems which seldom or never need to be recharged.


Using the constant ground temperature found at 8′ and below, geothermal or “ground source” heat pumps are the most efficient form of heating and cooling available. The most efficient gas furnaces have an efficiency rating of 94%, this means for each unit of fuel 94% is converted into usable heat ($1 worth of fuel gets you 94 cents of heat). Geothermal delivers a 400% efficiency rating. 4 units of energy are delivered for every 1 unit of electrical energy. Geothermal systems are transferring heat from the ground, not creating it by burning something. The heat and air conditioning the Earth provides from beneath your feet is free and never ending.

Safety & Air Quality:

There is no combustion in a geothermal heat pump, therefore there is no chance of carbon-monoxide poisoning. You WILL achieve a high indoor air quality.

Worry Free Maintenance:

Carbon monoxide, gas leaks and costly preventative maintenance are problems of the past once you have switched to a safe, dependable and efficient modern geothermal system. All components are shielded from the elements, which means they last longer. Fewer moving parts means less maintenance. The geothermal loop installation will last a lifetime, the indoor system will last up to 25 years. There is no noisy outdoor compressor or fan which means a much quieter system.

Quiet Operation:

Unlike air conditioners or heat pumps there is no outdoor unit. Geothermal units are very smooth and quiet in operation, comparable to a refrigerator. Geothermal units are also very reliable since the units are not subjected to wear and tear caused by snow, rain, ice, or vandalism.

Positive Cash Flow:

Geothermal is an investment. For many retrofit applications and especially new construction the energy savings more than offset the cost of installation over a short period of time. Think of geothermal in terms of Net Present Value (NPV). If you install a system which produces significant cash flow savings over its lifetime with a salvage value (equal to the value of the ground loop), the NPV is almost always positive. Many people want to know the “payback” period. We often ask these individuals what the payback period is on their car, or the current payback period of their gas furnace, there is none. Geothermal will produce energy savings, which will equal and exceed the cost of the system installation over a period of time. That period of time is dependent on the situation, but with the recent 30% tax credit the period has decreased nicely.
