Geothermal Installation

What Is a Geothermal Heat Pump?

Geothermal heat pumps work by tapping into the consistent temperatures just a few feet below the surface of the earth. Instead of generating heat by burning fuel or relying on outside air like traditional HVAC systems, geothermal systems transfer heat to and from the ground using a series of underground pipes—called a ground loop—and an indoor heat pump unit.

In the winter, the system absorbs warmth from the earth and brings it inside. In the summer, it removes heat from your home and transfers it back into the ground. Because the temperature underground stays steady year-round—around 50 to 60 degrees in Central Indiana—these systems work efficiently in every season without overworking themselves.

Geothermal HVAC installation involves digging or drilling to install the loop system horizontally or vertically, depending on your property. Once installed, the loop is connected to the heat pump indoors, which then distributes conditioned air through your existing ductwork. It’s a clean, quiet, and low-maintenance way to heat and cool your home.

Good Candidates for a Geothermal System Installation

While geothermal can work for many homes, you’re most likely a strong fit if:

• You’re building a new home or doing a major remodel. Installation is easiest when done during construction or large-scale updates.
• You have outdoor space for a ground loop system. Yards with adequate room allow for horizontal or vertical loop installation.
• Your current HVAC system is nearing the end of its lifespan. Replacing it with a geothermal heat pump can increase comfort and cut utility costs.
• You’re dealing with high energy bills. Homes that use electric resistance or propane heat can see big savings.
• You plan to stay in your home long-term. Geothermal systems offer decades of performance and major return on investment.

Experience the Benefits of Geothermal Heating and Cooling

A geothermal HVAC system isn’t just an energy upgrade—it’s a whole-home comfort solution that works quietly in the background, saving you money and hassle day after day.

Cut Your Utility Bills in a Big Way

Because geothermal systems use steady ground temperatures instead of constantly adjusting to outdoor extremes, they use far less energy to heat and cool your home. Homeowners often see savings of up to 70% on monthly bills compared to traditional HVAC systems.

Get More Years Out of Your System

With fewer moving parts and no outdoor components exposed to the elements, geothermal systems are built for durability. The indoor unit can last 20–25 years, and the underground loop can last 50 years or more with minimal maintenance.

Enjoy Quiet, Steady Comfort Year-Round

No more clunky start-ups or big swings in temperature. Geothermal systems deliver smooth, even heating and cooling without the noise or frequent cycling of conventional equipment. It just works—quietly and consistently.

Reduce Your Environmental Impact

Geothermal HVAC installation significantly cuts down on greenhouse gas emissions and electricity use. By choosing a system that relies on renewable ground energy, you’re making a cleaner choice for your home and the planet.

Take Advantage of Valuable Incentives

Installing a geothermal heat pump can qualify you for federal tax credits and local utility rebates in Indiana. These savings help offset the initial cost and improve your return on investment over time.

A properly installed geothermal system is built to last, and with our expert guidance and ongoing support, you’ll get dependable comfort and long-term value for decades to come.

What Does It Cost to Install a Geothermal HVAC System?

The cost of geothermal unit installation varies depending on your home’s size, the type of ground loop (horizontal or vertical), and how much site work or duct modifications are needed. While it’s a bigger upfront investment than traditional systems, the long-term savings on energy bills—and potential tax incentives—make it one of the smartest choices for efficient home comfort.
