Typically, a complete geothermal
To install a geothermal heat pump in 2,000 square foot home it will cost between $15,000 to $38,000 based on the system size and loop type. This is double the price of of a conventional HVAC system, but the savings on utility bills will be beneficial in the long run. Find the best HVAC contractors in your area.
Running a geothermal heat pump costs about $100 to $200 per month, but you'll be able to enjoy the savings of a heat pump compared to running a traditional HVAC system. According to the U.S. Department of Energy, a geothermal heat pump can save you up to 65% on your heating and cooling costs.
On average, a homeowner can expect total expenses to reach between $18,000 to $30,000 on geothermal heating and cooling cost. This cost would cover a complete geothermal installation. The price can range from $30,000 to $45,000 with high-end ground-source heat pump systems for large homes.
Typically, this payback period can range between 5 and 10 years. However, it's important to note that this is a ballpark figure and the actual payback period will depend on several factors.
According to the Environmental Protection Agency (EPA), property owners who install geothermal heat pumps can save up to 70 percent on heating costs and up to 50 percent on cooling costs, adding up to more than $1,000 in savings yearly.
Ground source heat pumps (GSHPs) for heating and cooling use 75% less energy than traditional heating and cooling systems. The U.S. has tapped less than 0.7% of geothermal electricity resources; the majority can become available with Enhanced Geothermal System technology.
Electric usage will increase with geothermal in winter months, but the additional cost won't be divided equally throughout the year. Because your electric bill will be lower in the summer than you paid previously, you'll be spending less money overall than when heating and cooling with a conventional system.
Geothermal heat pumps last significantly longer than conventional equipment. They typically last 20-25 years. In contrast, conventional furnaces generally last anywhere between 15 and 20 years, and central air conditioners last 10 to 15 years.
Horizontal ground loops are installed over a wide area of ground, so this type of system requires enough space to dig trenches hundreds of feet long and 6-10 feet deep. Horizontal ground loops can only be used when adequate yard space is available and trenches are easy to dig.
Expensive source of energy
As previously mentioned, most geothermal resources cannot be utilized in a cost-effective manner, at least not with current technology, level of subsidies, and energy prices. The upfront costs of geothermal heating and cooling systems for homes and commercial buildings are also steep.
Geothermal power stations in the United States are located exclusively within the Western United States where geothermal energy potential is highest. The highest concentrations are located in the Mayacamas Mountains and Imperial Valley of California, as well as in Western Nevada.
Geothermal will absolutely increase the resale value of your home because you now have the most energy efficient heating and cooling system available. This makes it more lucrative to potential buyers.
Land is required for the installation of a geothermal system's earth loops. The exact amount of space will be determined by the system loop type and size being supported, but it typically ranges from 400 sq. ft. to 8000 sq. ft.
When it's cold outside, air source heat pumps can struggle to heat the cold air. Geothermal heat pumps, meanwhile, take heat from the Earth's constant ground temperature (45° to 75℉ depending on your location) to heat your home. High-efficiency geothermal systems tend to operate between 100 to 120℉.
A 30% federal tax credit for residential ground source heat pump installations has been extended through December 31, 2032. The incentive will be lowered to 26% for systems that are installed in 2033 and 22% in 2034, so act quickly to save the most on your installation.
Air and water pollution are two leading environmental issues associated with geothermal energy technologies. Additional concerns are the safe disposal of hazardous waste, siting and land subsidence. Most geothermal power plants require a large amount of water for cooling or other purposes.
A geothermal system uses the heat stored in the earth to heat your home and returns heat to the earth to cool your home. The earth is a huge solar “battery”, the ultimate reliable and renewable resource.
Here are some of the key areas where your system will require protection: Freeze Protection: One of the primary reasons closed loop geothermal systems require protection is the threat of freezing temperatures. The Heat Transfer Fluid (HTF) used in these systems circulates through pipes buried underground.
Affordable. Geothermal pays for itself in just five to seven years with up to 70% savings annually on heating and cooling costs. And all geothermal installations receive a 30% energy tax credit through 2032.
According to the EPA, a geothermal heating and cooling system can reduce energy consumption and corresponding emissions by more than 40 percent as compared to an air-source heat pump, and by over 70 percent as compared to standard heating and cooling equipment.
Another barrier to widespread geothermal use is investment cost. “Geothermal is capital-intensive,” he notes, requiring comparatively higher initial investment than some other energy sources. Yet operational costs in the long run are basically zero, and geothermal is affordable, he adds.
The average cost to install a geothermal heat pump typically ranges from $10,000 to $30,000, depending on factors like the size of the system, property location, and installation complexity. Horizontal loop systems tend to be less expensive, while vertical systems, which require deep drilling, are on the higher end.
Clogged Air Filters: Neglecting regular maintenance such as cleaning or replacing air filters can lead to their clogging, restricting the airflow. Reduced airflow can compel the heat pump to work continuously to maintain the desired temperature, leading to increased wear and tear on the system.

Digging these trenches yourself would not be advised if you didn't have access to an excavator and possess some experience using it. This is ok though, as most people who choose to install geothermal systems on their property take no shame in hiring a contractor for this difficult aspect of the job.
