What Is Geothermal Heating & Cooling?

Geothermal HVAC systems use the energy trapped beneath the soil to heat or cool your home. Because the ground beneath your home maintains the same temperature year-round, it’s possible to cool and heat your home with one system in both summer and winter.

While there are different designs, the basics of geothermal systems remain the same. Heat pumps channel fluids through the ground to heat and cool your home. In the winter, the system draws heat into the home, and in the summer, it pulls heat from your home.

This energy-efficient process keeps your home comfortable regardless of the outdoor temperature. Plus, geothermal heating systems won’t lose efficiency on days with extreme temperatures, unlike air source heat pumps.

Benefits of Geothermal Heating & Cooling

There are plenty of benefits that you’ll enjoy when you install a geothermal heating system, including:

  • Energy efficiency
  • Lower utility bills
  • Consistent comfort
  • Longer HVAC life span
  • Minimal maintenance
  • Increased home value
  • Enhanced system reliability and performance

Different Types of Geothermal Systems

There are many types of geothermal HVAC systems, and we can help you determine which is best for your property. We consider a wide range of factors, including location, nearby access, plot size, efficiency, and more.

Our skilled HVAC contractors service a broad range of geothermal systems, including:

  • Closed-Loop: These continuously circulate antifreeze and water within buried or submerged pipes.
  • Horizontal: Buried at shallow depths, these systems circulate heat-transfer fluid over broad areas of land.
  • Vertical: The pipes in these systems are typically buried between 200 and 500 feet underground.
  • Pond/Lake: These geothermal systems are positioned within lakes or ponds that are at least 10 feet deep.
  • Open-Loop: These utilize aquifers and circulate the water to a geothermal heat pump within your home.
  • Hybrid: Hybrid systems use both geothermal sources and conventional heating systems to deliver even, balanced heating and cooling.

Geothermal Repair & Maintenance

Our team has the experience and expertise necessary to quickly identify the cause of your geothermal system issues. We can repair bad pumps, leaky gaskets, improper ground loop pressure, dirty air filters, or any other issue.

You should schedule geothermal repair services if you notice:

  • Inconsistent heating
  • High electric bills
  • Rattling sounds
  • Increased humidity
  • Burning odors

It’s also important to schedule routine geothermal maintenance to keep your system in good condition. Our HVAC technicians will change the air filter, inspect and clean the condensers, and perform other maintenance tasks as required for your specific system.
