What is Geo-Thermal?

Geo-thermal is a system that uses consistent ground temperature to heat and cool your home, giving you a higher-efficiency system with less operating cost. Geothermal systems are the most efficient and environmentally friendly way to heat and cool your home. Geo-thermal does require a nominal amount of land surface area to accommodate the system.

Here in Florida, we maintain a consistent, year-round 72 degree ground temperature. This allows us to use those temperatures in the summer to cool our home, and in the winter to heat our home. Traditional heat pumps use 5 units of power or purchased energy to produce heating and cooling comfort in your home.

Geo-thermal heating and air uses one unit of purchased energy with 4 units of stored energy from the ground. This is the reason a Geo-thermal system is extremely more efficient than ordinary heat pumps. Geo-thermal systems do not burn the amount of fossil fuels needed to provide heating and cooling in your home as a traditional heat pump would.

If you are considering Geo-thermal energy for your home, don't forget the pool - consider heating it with free Geo-thermal heat. A Geo-thermal system has a typical life expectancy of 20 years, while the ground loop material has a 50-year warranty with a 75-year life expectancy, all when properly maintained. Maintenance costs are equivalent to those of a conventional heat pump system.

Geothermal Pros & Cons

Geothermal energy pros and cons can assist you in saving a substantial amount of money on your annual power bill if grasped properly.


Did you know that the #1 cost of your energy bill is from the cooling and heating efforts of your home? The 2nd is hot water cost. These are both things that are generally used every day in homes across the country. It has become a major factor for environment pollution since fossil fuels are used. Thanks to recent innovations customers now have many different options that are environmentally friendly and reduce energy costs. Geothermal energy. This option may not be for everybody, but it is a great source of alternative energy for heating and cooling your home. You do need at least 2 acres of clear land for this type of system.

There are many pros and cons when it comes to geothermal energy. Take them into account to help determine if it is a source your home should be utilizing. Before you decide to install a geothermal energy system, take a look at the pros and cons listed below, and then call us for more information!

Some of the benefits of a geothermal energy system include the following factors:

Saving You & Your Family Money

With the installation of a geothermal energy system, you can cut your heating and cooling costs between 20 to 80%. The true amount that your home will save is dependent on a few different factors, including previous use of energy in your home, and the efficiency rating given to your heat pump when it was installed.

Also, with time your ground source heat pump could pay for itself. How long that could take is dependent on the surrounding factors of the heat pumps installation. When a geothermal energy heat pump is installed in a new construction home, they can pay for themselves in a faster time period than a home that is already existing. Usually, the heat pump pays for itself in 3 to 7 years. Currently there is a 30% Tax Credit Rebate offered by the Federal Government until Dec 31, 2016.

Variety of Uses

Some geothermal energy heat pumps on the market can also be used to heat the water in a home. So just by running your geothermal system for heating and cooling your home, you will also have a source for hot water that is free! This will help to lower the cost of hot water production by your water heater, saving your family even more money!

Environmentally Friendly

Did you know that when you decide to install a geothermal energy source to power your homes cooling and heating needs, you are installing a renewable source of energy? What this means, is that it can never be used up. Since the power comes from the ground, the source will always be available and can be obtained at a much smaller rate than non-renewable resources.

Currently, these is also a 30% tax rebate for Geo-Thermal systems installed.

In addition to this, when you choose geothermal energy you will reduce the levels of pollution used in heating and cooling your home. It has been found that even with the low amount of geothermal systems being used today, there has been nearly 6 million metric tons of carbon dioxide saved!

Other pros of geothermal energy that may be appealing to you as well, include but are not limited to:

  • Heating with geothermal energy is almost completely emission free.
  • This process means that there is absolutely no carbon released.
  • Since the ground is consistent with it's temperature, there are no fluctuations in the heat or cooling capabilities of your geothermal energy power source.
  • Out of all of the major power sources, geothermal energy has the smallest carbon footprint.
  • 30% Tax Rebate until Dec 31, 2016

Cons of Using Geothermal Energy

Cost of Installing the System

Geothermal energy is still a new concept for private home use, so it is still fairly expensive to install. Especially when compared to the cost of installing traditional furnaces and air conditioners.

Though as the system is improved and becomes more widely available, the cost of installation will go down. Over time the initial installation costs will be covered by the energy that your system saves you. But if you and your family do not have the upfront costs to install a geothermal system, then you may find the cost to be a financial burden compared to a traditional system. In addition, you will need a minumin of 2 acres of land for this system.

Cost of Powering the Pump

Though you will be using the ground as a source for energy to heat and cool your house, the system still needs electricity to make the pump work. Your costs will be less, but you will still need to make sure you have payment available for the energy supplied to the heat pump. Regular air source heat pumps need 5 units of purchased energy to heat and cool your house. Geothermal systems get 4 of the 5 unites from the ground, so this will lower the cost greatly because you will only need to pay for 1 unit of energy.

Large Land Consumption

When you start the installation process of a geothermal energy system you will need a minimum of 2 acres of land for the system to be properly installed. The loop system for Geothermal is generally required to be laid out in a horizontal pattern, but for an extra cost you can have this done in a vertical pattern.

Other potentially negative factors for this source of energy include, but are not limited to:

  • Where exactly the system can be installed is extremely dependent on the specific location and usually requires more land than the average home has available (especially those in subdivisions and mapped neighborhoods). The minimum land requirement is about 2 acres.
  • The installation of the equipment is also extremely expensive.

Bottom Line when Considering Geothermal Energy Advantages and Disadvantages

When it comes down to it, geothermal energy is a very environmentally friendly way to heat and cool your home while also providing you with a free secondary hot water source. It is a sustainable system that provides virtually an endless supply of energy. With no limitations on the amount you can use, because it will never run out! Geothermal is also very reliable. From these facts, it makes geothermal energy an obvious choice for homeowners who can afford the installation prices.

If you are interested in getting a geothermal energy system installed, you need to carefully consider the pros and cons before making your decision. As this is a large investment into your own home, please feel free to call us with any questions you may have. We look forward to speaking with you.
