What Is Geothermal?

Whether it’s a frigid winter evening or a scorching summer afternoon, you should feel confident your HVAC system will keep your home comfortable without costing you a fortune. That’s exactly what a geothermal heating and cooling system is designed to do.

Regardless of outdoor conditions, the ground 10 feet below the surface of the earth maintains a near-constant temperature year round. That subsurface temperature is warmer than the average winter temperatures in the upper Midwest area and cooler than average summer temperatures. Geothermal systems use that steady, below-ground temperature to heat and cool your home.

Does Geothermal Heating Really Work In Cold Climates?

How Does Geothermal Energy Work?

Geothermal heating and cooling systems work by transferring heat either into or out of your home. When it’s cold outside, the system pulls heat from the ground and transfers it indoors; when it’s warm outside, the system pulls heat from the air within your house and deposits it into the ground.

Here’s how the process works:

  • A geothermal heat pump is installed inside your home. This pump typically replaces a traditional furnace and air conditioning system. It uses refrigeration like in a refrigerator, A/C, or freezer to extract or input heat into the liquid flowing through the underground pipes back into the earth. This results in delivering steady 110 degrees of hot air for heating in the winter, or 60 degrees of chilled dehumidified air in the summer. This system can also be used as a water heater for domestic use or for radiant floor heating.
  • Underground pipe systems, called ground loops, connect to the heat pump and are buried approximately 10 feet below the surface of the ground outside your home. These ground loops continually circulate temperature-conducting fluid that collects and transfers heat either into or out of the earth.
  • As the fluid moves through the ground loop, it changes temperature according to the subsurface temperature of the ground.
  • In winter, the geothermal heat pump concentrates the heat from the fluid and transfers it into your home to warm the space. In summer, the heat pump collects heat from your indoor air and transfers it into the fluid-filled ground loop. As the fluid circulates, it deposits that heat into the earth.

Benefits of Geothermal Heating & Cooling Systems

Because the subsurface temperature of the earth remains relatively constant, geothermal systems are remarkably energy efficient. Since these systems take advantage of the existing temperature within the ground, they don’t create heat through combustion or use hot outdoor air to exchange heat in the middle of summer (that is why air conditioners struggle to keep up on hot days). Instead, they simply collect heat and move it to the appropriate area. Discover the full benefits of switching to geothermal.

How Much Can You Save With Geothermal?

Myths About Geothermal Energy

Here’s what you’ll enjoy when you opt for geothermal heating and cooling:


Significant Energy Savings

Because geothermal systems rely almost entirely on renewable energy, you’ll enjoy major long-term cost savings. Geothermal heat pumps are up to four times more efficient than traditional HVAC systems, which means you can save up to 65% on your annual energy bills!

Comprehensive Heating and Cooling

Geothermal is the only HVAC option that delivers air conditioning and heating using a single system.

Peace of Mind

Unlike a traditional HVAC system, geothermal heating doesn’t involve any flames or fuel and geothermal cooling doesn’t require any refrigerant. You’ll enjoy peace of mind knowing your household is safe from hazardous gases like carbon monoxide, nitrogen dioxide, sulfur dioxide, and freon.

Minimal Maintenance

With geothermal, you won’t be calling for frequent maintenance or service visits. When properly installed, a geothermal system typically only requires periodic checkups, coil cleaning, and filter changes.


The average geothermal heat pump lasts between 20 and 25 years without extensive maintenance. Geothermal ground loops typically last upward of 50 years, but they can last up to 100 in some cases!

Smaller Environmental Footprint

Geothermal heat pumps rely largely on renewable energy, which means they’re an excellent way to reduce your household’s environmental footprint. Oil-burning heating systems, on the other hand, are a close second to automobiles in terms of fossil fuel consumption.

Tax Incentives

Geothermal can net you major savings on your taxes. Federal, state, and utility tax incentives for geothermal installations can dramatically lower your initial system investment.
