How Do Standard and Geothermal Heat Pumps Work?

Both systems are heat pumps, meaning they do not burn fuel to create heat. Instead, they move heat from one place to another and reverse that process to cool your home in summer.

A standard air-source heat pump pulls heat from outdoor air, even cold air, and moves it indoors. A geothermal heat pump, also called a ground-source system, exchanges heat with the ground through a buried loop of pipe.

That difference matters in Michigan. On a 5-degree January morning, an air-source unit has to work harder to pull heat from frigid air. A few feet underground, temperatures stay much steadier, often in the low 50s.

Standard vs. Geothermal Heat Pumps: How Much Does Each System Cost?

A standard air-source heat pump typically costs less to install because it does not require excavation, trenching, or drilling.

A geothermal system costs more upfront because the ground loop must be installed on your property. Lot size, soil conditions, and whether the loop is horizontal or vertical can all affect the final price.

Operating Cost and Efficiency Over Time

Once installed, geothermal is one of the most efficient HVAC systems available for a home. Because it works with stable ground temperatures, it avoids the biggest efficiency drops that air-source systems can experience during extreme cold.

Geothermal systems can also last much longer. A standard heat pump may last 10 to 20 years, while geothermal indoor components commonly last 20 to 25 years and the buried loop can last 50 years or more.

That longer service life is where geothermal starts to make more sense. The longer you stay in the home, the more time you have to recover the higher upfront cost through lower heating and cooling bills.

Rebates, Tax Credits, and Financing

For years, federal tax credits helped reduce the cost of qualifying geothermal installations. For new residential installations completed in 2026 or later, the federal geothermal tax credit is no longer available.

That means state and utility incentives are now the main source of savings. Available rebates can vary by location, income, program funding, and utility provider.

Depending on installation cost, local energy prices, and available incentives, geothermal may pay back faster in favorable situations or take longer in others. Financing can also help spread the upfront investment over time.

Which Heat Pump Is Right for Your Home?

Choose a Standard Heat Pump If:

• You are working with a tighter upfront budget
• You may move within the next several years
• Your lot is too small or difficult for a ground loop
• You want a simpler installation process

Choose Geothermal If:

• This is your long-term home
• Your property can support a horizontal or vertical loop
• You want the lowest long-term operating costs
• You value longer equipment life

Not every home is a good geothermal candidate. A cramped lot, challenging soil, or short ownership timeline can make a standard heat pump the smarter choice.
