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 opposite 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 underground 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:
- 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.
- 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.
- 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.
- 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 About Tax Credits for Geothermal?
The federal Residential Clean Energy Credit, which covered 30% of the cost of a geothermal heat pump system, ended for systems installed after December 31, 2025. If your system was installed in 2025 or earlier, ask your tax professional whether you can still claim it on that year's return.
Even without the credit, geothermal is still the most efficient way to heat and cool a home. The ground loop can last for decades, and operating costs are typically far lower than heating with propane, fuel oil or electric resistance heat. When we quote your project, we'll walk you through the expected operating costs and let you know about any utility rebates or manufacturer promotions that apply.
