The Benefits of Geothermal

Charleston: Morelli Offers the Benefits of Geothermal for Your Home and Business

Even the most environmentally-conscious among us can hesitate to invest in a geothermal HVAC system. It’s easy, after all, to get distracted by a higher installation cost and the disruption of your landscaping – but when you look at the benefits of a geothermal system, they easily outweigh these cons.

Consider this list of the benefits of geothermal:

Free Energy

With mounting utility costs, free energy sounds too good to be true. But the earth is a free heat source and heat sink as long as we invest in the technology to harness it. Geothermal systems are indeed supplemented by some paid energy: electricity.

But the amount of electricity is far less than units using only electricity for heating and cooling. In fact, the earth’s heat helps geothermal systems use 25 – 50% less energy than conventional HVAC systems. Electricity is a supplement, not the main meal.

Because of this lower energy usage, geothermal systems save you so much on your energy bills that most systems pay for themselves in 3-5 years.

Little Maintenance

Besides cheaper utility bills, you’ll have lower repair and maintenance bills. Geothermal units have few moving parts. The HVAC unit with its compressor, fan, and pump is entirely indoors and easily serviced. It’s not subject to the wear and tear of the elements. Periodic checks and filter changes can give your geothermal system at least a 20-year lifespan.


When you use fossil fuels like oil for your heating and cooling system, the combustion releases carbon monoxide, which is dangerous to humans and the ozone layer. Geothermal systems don’t rely on fossil fuels or combustion. Therefore, there is no risk of carbon monoxide leaks, flames, or odors inside the home. It’s also greener for the planet.

Tax Incentives

Federal, state, and local governments were smart enough to see the benefits of geothermal from an environmental standpoint. Therefore, there are plenty of rebates and other incentives offered to geothermal consumers.

The Energy Improvement & Extension Act offers a 30% residential, 10% commercial one-time tax credit based on the total cost of installing a geothermal system. It’s valid through the end of 2016. Talk to your tax professional for information on the tax credit. Make sure your system meets Energy Star eligibility requirements and save receipts for this incentive.
