Explore the Benefits of Geothermal Systems

Geothermal energy has been used for decades to heat and cool buildings. Also known as geo-exchange, ground-water, water-source, or water furnace systems, the technology harnesses the earth's natural energy to power heating and cooling for residential and commercial properties.

• Uses stable temperatures beneath the earth's surface
• Reduces your carbon footprint and saves on energy costs
• Provides reliable year-round comfort
• Engineered to run quietly, indoors and out
• Operates at lower speeds to minimize noise levels and is quieter than a refrigerator

Geothermal Systems: Efficient and Cost Effective

Geothermal systems are rated #1 in energy efficiency, delivering over five units of energy for every single unit of electricity used. Efficiencies can reach over 530% in efficiency, compared to the most efficient gas furnace at 98%.

It's also cost effective. Most homeowners save more on their monthly bills than they pay when financing installation, and many see a return on investment of 10-20% over the system’s lifetime.

Geothermal systems don't use natural gas, propane, or oil and there's no combustion, flames, or fumes. You and your family will face no risk of carbon monoxide poisoning.

Eco-Friendly Geothermal Systems

Recognized by the EPA as environmentally friendly, geothermal systems offer energy-efficient heating and cooling technology. Each installation is like planting 750 trees and reduces the impact of fossil fuels on the environment.

As a renewable resource, your unit will operate 24/7, 365 days a year, regardless of the weather. It works efficiently, no matter the climate or conditions, providing heating, cooling, and supplemental hot water for your entire home.

In your home, geo systems provide superior indoor air quality. Equipped with MERV 11 filters, they filter out dust and pollen, circulate air more frequently, and ensure consistently clean air. They're also flexible, offering multiple configurations that make them perfect for both new construction and existing homes.
