What is a Geothermal Heat Pump? Technology Explained

When most people hear the term “HVAC system”, the first thing that comes to mind is usually an air conditioning unit. Whether you have one installed in your window or in your attic, they’re key to cooling your home during the summer. However, AC isn’t the only option for controlling the temperature in your home. 

A geothermal heat pump is another way to move heat in a building. But what is a geothermal heat pump, and why should you know about it? 

Here are some of the benefits and how much they cost to install.

What is a Geothermal Heat Pump?

An ordinary heat pump works by extracting heat from the air and moving it either inside or outside of your home. Refrigerant is utilized to absorb heat, allowing for cool air as well.

A ground source heat pump works in a similar fashion. Instead of transferring heat via the air, it does so using the ground beneath your home. 

The ground heats and cools at a different rate underground compared to above ground. As such, you can pull heat from the ground during the winter or deposit heat underground during the warmer months. 

How Much Does a Geothermal Heat Pump Cost?

Installing any new HVAC system is never an inexpensive ordeal. When purchasing a geothermal heat pump, you have to take into consideration the size of your home and the type of system you install. 

Although the market has been growing in recent years, you should still expect to pay between $12,000 to $30,000 for your new system. Larger homes may pay up to $45,000 for a high-end one. 

Even though you’ll want to save money after making the purchase, avoid trying to DIY any necessary repairs. You may void your system warranty or reduce its efficiency. 

Benefits of a Geothermal Heat Pump

One of the benefits of a geothermal heat pump is its efficiency. Compared to a standard heat pump, it’s roughly twice as efficient when it comes to its kilowatt-hours. A geothermal heat pump is also twice as efficient as most top-rated air conditioners. 

Even though they cost quite a bit to install, you should expect low operating costs with lower monthly bills. There are also federal tax credits that can help cover the cost of equipment and installation. 

A ground source heat pump can last you over 20 years with normal maintenance. Some come with controls that can be linked to a smart device through an app. 

A major point to keep in mind is that a new system can use your current ductwork with minor modifications.

So, what is a geothermal heat pump good for? It’s a low-cost way to generate heat and cool air using the ground beneath your home. They also last longer and are good for the environment.
