What Is a Geothermal system?

You've probably heard the term geothermal floated around but how exactly does a geothermal system work? There are different types of geothermal systems but we'll be discussing closed loop geothermal heating/cooling system in this explanation.

Geothermal is a highly efficient way to heat and cool buildings. It works by circulating a fluid, usually a mixture of water and antifreeze, through a series of underground pipes in the ground (or sometimes a body of water) close to the building. The fluid absorbs heat from the ground during the winter and transfers it inside your home, and does the oposite in the summer, providing both heating and cooling functions. The closed loop design ensures that the fluid remains contained within the system, with no direct exchange with the outdoors, making it a closed and self-contained system with almost no maintenance.

Because it takes advantage of the relatively constant temperature of the earth, it will provide consistent and reliable heating and cooling with minimal energy consumption as the heating/cooling is not provided by the system itself but by the ground. It also has low maintenance requirements since the only moving parts are the pumps that move the fluid through the undergound loop.

Is A Geothermal System A Good Option in Ohio?

Investing in a geothermal system here in Ohio can bring numerous benefits to your home. Here are some compelling reasons why you should consider buying a geothermal system:
  1. Energy Efficiency: Geothermal systems are known for their high energy efficiency. They can provide heating, cooling, and even hot water using a fraction of the energy compared to traditional HVAC systems. This can result in significant energy savings and lower utility bills over the long term.
  2. Comfort and Convenience: Geothermal systems provide consistent heating and cooling throughout the year, regardless of outdoor temperatures. They also eliminate the need for outdoor condensing units, which can be noisy and unsightly.
  3. Longevity and Low Maintenance: Geothermal systems are known for their durability and longevity. The ground loop can last for decades, and the indoor components have fewer moving parts compared to traditional HVAC systems, resulting in lower maintenance requirements and potentially longer lifespan.
  4. Increase Property Value: Geothermal systems are considered a desirable feature for many homebuyers who prioritize energy efficiency and sustainability. Installing a geothermal system can potentially increase the value of your property and make it more attractive to potential buyers.

What are the Tax Incentives for Geothermal?

Tax incentives for geothermal systems in Ohio vary depending on local jurisdiction. However, there are federal tax incentives available for geothermal heat pumps under the Residential Renewable Energy Tax Credit, which allows you to claim a percentage of the system's cost as a tax credit on your federal income tax return.

As of 2023, the federal tax credit for residential geothermal heat pumps is 30% of the total installed cost. It's important to note that tax incentives are subject to eligibility requirements, including system specifications, installation guidelines, and other criteria, so it's essential to thoroughly review and follow all applicable guidelines and regulations to qualify for the incentives.

    Dwight and his team have bailed us out more than once. First, he was the most responsive in an emergency call, and did amazing work for us. Then he later replaced the whole heating and … More cooling system, plus installed a wireless smart thermostat, and did amazing work. He communicates well, overdelivers, is prompt, does great quality work, really cares about the ultimate outcomes, and is just a pleasure to work with. We will keep using him for all our needs.
