Residential & Commercial Geothermal

Geothermal Systems offer homeowners and businesses the ability to reduce their carbon footprint while taking advantage of the most energy efficient heating and cooling system on the market. In fact, the U.S. Environmental Protection Agency (EPA) has called ground source heat pumps (geothermal heat pumps) the most energy-efficient, environmentally clean, and cost-effective space conditioning systems available. 

Homeowner’s with a properly installed Geothermal System can expect efficiencies that are 400 – 500% higher than those of the most efficient traditional heating and cooling system. As a result, these homeowners will experience long-term savings with the added benefit of hot water.

Geothermal Systems are also one of the cleanest, safest ways to heat and cool a structure. They operate on 100 percent electricity which means, no carbon monoxide, carbon dioxide or other greenhouse gases are emitted. Learn more about geothermal heat pumps here.


Geothermal Design and Installation


A new geothermal system is an investment and here at Rabe Hardware, we do our best to make the entire process easy and hassle free. Our geothermal experts can handle all aspects of the geothermal installation. Everything from performing a heat loss/heat gain calculation, so your system is properly sized to maximize efficiency and performance, to handling all paperwork including tax credits, utility rebates and warranties. Plus, our team is highly skilled in electrical, excavation, piping and HVAC to complete your project from start to finish.  That means better workmanship and customer service for you.

The installation cost on a geothermal system varies depending on factors such as equipment, application, geothermal ground loop, tax incentives and financing. While most geothermal installations cost more than a conventional heating and cooling system such as gas furnaces, propane furnaces and boilers; special financing, tax credits and utility rebates help make the initial investment more manageable. Plus, unlike traditional systems, the energy savings a geothermal system provides could pay for the system within 10 years – well within the warranty and life expectancy of the system.

Whether you’re considering geothermal heating and cooling in a new construction or existing home, Rabe Hardware is here to help you review your options and determine whether geothermal would be a good fit for you.

Geothermal FAQ's

The EPA and the U.S. Department of Energy recognize geothermal systems as the most environmentally friendly way to heat and cool. Unlike other comfort systems, geothermal does not emit carbon dioxide, carbon monoxide, or other greenhouse gasses which contribute to air quality pollution. There is no combustion in a geothermal heat pump; therefore there is no chance of carbonmonoxide poisoning. By adding high efficiency air cleaners with geothermal, a high indoor air quality level can be reached.

Geothermal systems typically have a lifespan of 15-20 years rather than a 7-10 year lifespan on a conventional furnace and air conditioning system. The ground loop of the geothermal system (the pipes buried in your yard) is made up of polypropylene pipe, the same pipe which is used in city gas lines, and they have a lifespan up to 50 years.

Geothermal is an investment. For many retrofit applications and especially new construction the energy savings will more than offset the cost of installation. On average, Geothermal heat pump users will see a 30%-70% reduction in their heating and cooling costs. That savings, over a period of time, plus utility rebates combined with Federal and State* tax incentives can roduce a return on investment in as little as 3 years. Recent studies have also shown an increase in home values for those with Geothermal systems due to the environmental impact and long-term savings.

A geothermal heat pump is an extremely competitive choice for a market forced to deal with rising energy costs and resource depletion because they are renewable and the most efficient heating and cooling system available today. Add in the fact that many ground source heat pumps can heat a home’s water for virtually no additional cost, you quickly realize that you can’t lose with a properly designed and installed geothermal heat pump.

It is true that a Geothermal heat pump installation can be more convenient during the construction. However, Geothermal heat pumps also provide a great option for replacing or upgrading an existing heating and cooling system to take advantage of this clean, safe & renewable energy.

As it turns out, geothermal is flexible and able to accommodate a variety of landscapes, from rocky, small-sized lots, to sprawling acreage. Numerous loop field installations have made it possible to install a Geothermal system just about anywhere.

A Geothermal heat pump is capable of providing consistent and adequate heating and cooling for your entire house as long as it is properly sized and installed. Make sure you only work with a contractor that is experienced and qualified in Geothermal heat pump design and installation to avoid any problems.

Although many parts of the country experience seasonal temperature extremes — from scorching
heat in the summer to sub-zero cold in the winter—a few feet below the earth’s surface the ground
remains at a relatively constant 55 degrees. So when the outside temperature is below freezing, a
geothermal heat pump should have no trouble extracting enough heat to keep your home 72 degrees or
more. Even when the ground freezes, the frost usually only extends three or four feet below the surface
which is not deep enough to effect the geothermal loop pipes which should be buried at least 7 feet
below the surface.

Archaeological evidence shows that over 10,000 years ago the North American Paleo-Indians settled near hot springs and were the first humans to use geothermal energy. Since many people live in areas without those hot springs, another way of harnessing the earth’s renewable energy was needed. So, in 1948 Professor Carl Nielsen of Ohio State University developed the first groundwater heat pump, for use at his residence. While modern advances in technology have increased the efficiency of these machines, the concept remains the same. Today, 85,000 geothermal heat pumps are installed annually across the United States and geothermal energy is considered an important step toward energy efficiency and the reduction of global warming.
