Residential Geothermal HVAC Systems

Whether you’re in a warm climate like sunny California or cold climate like snowy Michigan, a Ground-Fed Geothermal HVAC system (also known as a closed loop ground source heat pump, or geothermal heat pump system) that moves thermal energy in the form of geothermal heat between the ground and the home can free a homeowner from volatile energy prices, saving money on their energy bill. Geothermal heat is heat energy held at a constant temperature just a few feet under the surface of the Earth’s crust, is a very efficient and economical option for heating and cooling your home. Residential geothermal heat pump systems are the ultimate renewable source of heat and cool, so they are environmentally friendly and help to reduce the use of fossil fuels in the home.

How Does Geothermal HVAC Work?

To install a geothermal heating and cooling system in the home, a geothermal tap would need to be placed near the house, several feet below the surface of the ground. This tap is a closed loop system that is inserted into the Earth’s crust below the frost line, which remains roughly 50 degrees at all times, and uses the ground itself as a heat source. This constant temperature helps reduce heating and cooling workloads placed on the HVAC system as well as reducing the energy required by the residential HVAC system to heat or cool the house, making this a high efficiency HVAC system. All residential HVAC systems need some form of energy to move heat, and the movement of this heat has energy demands of its own. This is where geothermal energy stands out as a winner of energy efficient heating and cooling systems – by reducing energy use (and energy bills!) and lowering the overall carbon footprint of the home.

When the temperature sits at a constant 50 degrees, the demands for heating and cooling require much less energy, making geothermal energy an efficient and energy-saving alternative to traditional HVAC systems. Imagine needing to cool a 100-degree day with a traditional HVAC system. The energy needed to get to the point where the forced air HVAC system will be able to cool off the home during 100-degree weather is significant. With a geothermal cooling system, the energy load is already at the halfway point it needs to be to counter that 100-degree day with cooling. Now picture this same example, however a 0-degree day in the winter. A geothermal heating system, again, is at a better starting point than a traditional HVAC system to heat the home, making geothermal much more efficient in terms of operation, cost, energy usage, and environmental impact.  This greatly improves heat pump efficiency.

In addition to the tap and ground loop, the geothermal heat pumps include many elements within traditional forced air hvac systems, such as the air handlers, and duct work that you would expect to see in any modern home.  While the main source of thermal energy is provided by the geothermal heat pump, the air source is the same as that of any other system.

Investing in An Energy-Saving Alternative

The setup and installation for integrating a geothermal HVAC system in your home might have a bigger upfront cost than traditional systems. However, the long term energy savings from this efficient solution will offset any costs the homeowner pays for installation. 

In addition, the total annual operating costs of the system will be reduced by up to half the cost of a traditional home HVAC system, lowering your heating costs and cooling costs year round. Geothermal HVAC systems pay for themselves with an average payback period of roughly 10 years! Once this time frame is met, every year after, the system is saving homeowners a substantial amount of money.  Generally, these systems last for 18-23 years, almost double the lifetime of a conventional system, making a geothermal HVAC system a far better investment than traditional HVAC systems. 

Geothermal HVAC systems also significantly add to the home’s value, therefore further increasing the return made through this type of investment and opting for this type of solution. An added bonus, they also carry a large tax credit from converting to an energy-efficient home heating and cooling system!
