<p>Efficiency within a model group will tend to vary by the size (capacity) of the unit. Some products, like furnaces, may also be affected by installation orientation (horizontal, upflow, or downflow) or even by the nozzle used in installation, as is the case with boilers and oil furnaces. The efficiency of an air conditioner or heat pump can even be affected by the furnace or fan coil it relies on inside the home to move air. Products that fall into the “Select sizes ENERGY STAR<sup>®</sup> qualified” category include within their model group some non-qualified units due to either size or potential installation factors.</p>

What to Look for in a Residential Geothermal Heat Pump System
Energy Savings
As a renewable energy source, geothermal energy reduces your carbon footprint—a single geothermal heat pump can reduce greenhouse gas emissions by 11 metric tons over its 20-year lifespan. Geothermal heat pumps are rated by their Energy Efficiency Ratio (EER) and the coefficient of performance (COP) rating, which is much like miles per gallon (MPG) for a car: the higher the rating, the more energy-efficient the system.
Utility Savings
Geothermal HVAC systems can lower home cooling and heating operating costs compared to forced-air HVAC systems, with savings as high as 70 percent.
Sound Performance
Packaged geothermal heat pumps are an all-in-one system that do not require an outdoor unit and are fully insulated for very quiet operation. Our Infinity® split-system geothermal heat pump requires an indoor unit that will produce minimal sound. The ground source heat pump is installed outside your home and also features sound reducing technologies.
Reliability
Our ground source heat pumps are durable, and because they are located indoors, they can last for up to 20 years with little maintenance. Our split-system geothermal heat pump is also extremely durable and can last for up to 15 years with little maintenance.
Benefits of a Geothermal HVAC System
A geothermal HVAC system provides a highly cost-effective and energy-efficient solution by leveraging the constant temperature beneath the Earth's surface. Unlike air-source heat pumps, which rely on fluctuating outdoor air temperatures, a geothermal heating and cooling system transfers heat from the ground, resulting in more stable performance, lower energy use, and reduced reliance on fossil fuels. These systems also operate quietly and may have a longer lifespan compared to air-source heat pumps, which can make them a smart long-term investment. Geothermal HVAC systems provide year-round comfort and can potentially lower your heating and cooling costs.
Unsure Which Geothermal Heat Pump Is Right for Your Home?
Cost to Install a Geothermal HVAC System
The cost to install a geothermal HVAC system varies based on factors such as home size,and the type of ground loop system used. On average, homeowners can expect to spend between $12,000 and $45,000 for a complete installation, though the long-term energy savings and potential tax incentives can help offset the initial investment. While the upfront cost is higher than traditional HVAC systems, geothermal heating and cooling can offer significantly lower operating costs and a longer lifespan.

Frequently Asked Questions About Geothermal Heat Pumps
A geothermal heat pump is an energy-efficient heating and cooling system that utilizes the stable temperature of the earth to regulate indoor temperatures. It transfers heat between your home and the ground using a network of underground pipes filled with a heat-absorbing fluid. In winter, it extracts heat from the ground to warm your home, and in summer, it removes heat from your home and releases it into the ground. Learn more about what is a geothermal heat pump.
A geothermal heat pump works by transferring heat between your home and the stable constant temperature of the earth below the surface. In the winter, the system extracts heat from the ground and distributes it throughout your home, while in the summer, it removes heat from your home and transfers it back into the earth, providing geothermal heating and cooling year-round.
This process is made possible through a network of underground pipes, called a ground loop, which circulates a water-based solution to absorb and release heat. Unlike air-source heat pumps, which rely on fluctuating outdoor air temperatures, geothermal HVAC systems operate with greater efficiency, lower energy costs, and minimal reliance on fossil fuels, making them a cost-effective and eco-friendly solution for home comfort.
Yes, there are several types of geothermal heat pump systems, each designed to suit different landscapes and installation needs. The four main types include closed-loop and open-loop systems, with closed-loop systems further divided into horizontal, vertical, and pond/lake loops. Horizontal loops are ideal for properties with ample land, while vertical loops work better for smaller lots or rocky terrain. Pond/lake loops utilize a nearby water source for heat exchange, making them a cost-effective option when available. Open-loop systems draw groundwater from a well or pond and return it after heat exchange, offering high efficiency but requiring a consistent and clean water source. Choosing the right geothermal heating and cooling system depends on factors such as soil conditions, land availability, and climate.
Ground-source heat pumps are known for being is one of the most energy-efficient heating and cooling systems available, By leveraging the earth’s constant temperature, geothermal heating and cooling systems require less energy to maintain indoor comfort, leading to substantial reductions in utility bills. Additionally, homeowners may qualify for federal tax credits and local incentives that help offset installation costs. To learn more about system performance and savings, visit our page on geothermal heat pump efficiency.
The main disadvantages of geothermal heat pumps include the high upfront cost and the complex installation process, requiring significant space for underground loops and specialized equipment. Installation limitations may arise in urban areas or small properties.
