What Is Geothermal?

Geothermal heat pumps operate almost exactly the same way as standard heat pumps. Heat pumps use the fluctuating air temperatures as the heat exchange medium; geothermal heat pumps use the constant temperature of the earth to heat and cool your home or office.

According to the Department of Energy, this allows the system to reach efficiencies of 300 – 600 percent even on the coldest winter nights, compared to 175 – 250 percent for air-source heat pumps on cool days.

Despite extreme temperatures throughout the year, the ground 20 feet below the earth’s surface remains relatively stable in temperature—making it an extremely reliable heat exchange medium. However, your geothermal heat pump will also be installed with backup heating to ensure your home or office never lacks for comfort.

Types of Geothermal Heat Pumps Installed in Nazareth

There are four basic types of ground loop systems:

  • Horizontal – these are ideal for residential installation when there is sufficient land available and vertical installation is difficult.
  • Vertical –these are an excellent option for commercial buildings because they do not require a large amount of space to be installed. They can be installed under the parking lot. This is often the most effective residential installation in Northampton County.
  • Pond/lake –if there is an adequate body of water, water-source heat pumps are another option and can be very cost-effective. However, the suitability must be carefully evaluated.
  • Open-loop –this type of system uses well or surface body water as the heat exchange fluid that circulates directly through the geothermal heat pump. We always return the water to the same depth. Water quality is critical in this type of installation.

The Benefits of Geothermal

There are many benefits to installing geothermal heat pumps in the Nazareth area:

Reduced Energy Consumption

The main benefit of installing a geothermal heat pump is that they use 25 – 50 percent less electricity than conventional heating or cooling systems.* That means that a geothermal heat pump can use one unit of energy to move three units of heat from the earth.

Environmentally Friendly

Since geothermal heat pumps are so efficient, they can greatly reduce the amount of emissions required to heat and cool your home. In fact, geothermal heat pumps can reduce energy consumption up to 44 percent compared to air-source heat pumps and 72 percent compared with standard air conditioning equipment!*

Durable Construction

Geothermal heat pumps have very few moving parts, and the parts that are moving are safely kept indoors. This means that your system can last 20 years or more!

Minimal Noise

These systems have no outside condensing units, so there is no noise outside the house or commercial building.

Great Service




We chose Jack Lehr due to a prior good experience with Ben who worked with us on our Air Cond system. Ben was very efficient and we appreciated the fact that he took the time to answer our questions.This time we had an electrical issue and the technician (Caleb) performed in the same manner. It was very reassuring to watch him work and also to have him tell us what he was doing, recommendations for some of our issues, and answering any of our questions.
