Geothermal Systems

With a geothermal heating and cooling system from A Quality, your land turns into a power plant for your home. The geothermal system is a smart way to reduce your carbon footprint and utility bills at the same time. Geothermal systems use the free, renewable energy found in your own back yard to save up to 70% on heating, cooling, and hot water costs. If you are considering geothermal system installation in Maryland or southern Pennsylvania, A Quality can provide the necessary assistance and expertise. We have installed geothermal systems for customers in Baltimore County, Anne Arundel County, Howard County, and many other locations.

Why Geothermal?

A geothermal system saves you money, it is a green provider of energy, and it will pay for itself. For every kilowatt of electricity you place into a geothermal system, you get 3-5 kilowatts FREE from the ground. Studies conducted by the EPA have found that geothermal heat pumps can help reduce consumption of electric and harmful emissions compared to traditional HVAC systems up to 40% for every geothermal system installed, which is an equivalent of taking two cars off the road and planting one acre of trees.

Geothermal operating costs compared to conventional systems in a residential home

Over 70% of the energy consumed by a typical house is used for heating, cooling, and hot water

Total energy consumption is half that of a conventional system! Forty-nine percent of the energy is free energy from the earth.

As you can see, a properly installed geothermal system has the potential to cut your energy bill in half. These savings will allow you to recoup your initial investment in just 2-3 years. There are also immediate benefits, such as quiet system operation and even temperatures. To find out how much you’ll be able to save with geothermal, take advantage of our Savings Calculator.

Types of Geothermal Heat Pump Systems

There are four basic types of ground loop systems. Every kind of system can be used for residential and commercial building applications.

This type of loop system is generally the most cost-effective option for residential installations, especially for new construction where sufficient land is available. This type of system is installed within trenches that are between four to seven feet deep. A series of plastic pipes are laid inside of the trenches and connected to the heat pump. A typical horizontal loop will be 400 to 600 feet long for each ton of heating and cooling.

Vertical loop systems are commonly used for commercial buildings with limited space. It starts by drilling vertical holes in the ground that are anywhere from 150 to 400 feet deep. Then, a single loop of pipe with a U-tube at the bottom is installed. The hole is then sealed with grout to ensure adequate contact with the soil. Lastly, the vertical ground loops are connected to a horizontal underground header pipe that is responsible for carrying fluid to the unit.

If a building is located near a body of water, a pond/lake system may be the most economical choice. A supply line pump is run underground to the body of water and is coiled into circles at least eight feet underground to prevent freezing. In order for this type of system to work, it must be placed in a body of water that meets its minimum volume, depth, and quality criteria. It’s important to note that pond/lake loops have no adverse impact on the aquatic environment.

This type of system is only possible if there is sufficient groundwater available via a well, lake, or river. The water source must be of good quality and comply with local groundwater discharge codes. Since the system is open, a water pump is placed directly into the geothermal unit and then discharged into a return well or a body of water. The system does not affect the water’s quality.


There are three parts to a geothermal system: the ground loop, the flow center, and the indoor heat pump.

The ground loop utilizes the temperatures of the ground to transfer heat from one place to another using a ground loop field buried underground. The loop field circulates a water-based solution through a series of pipes.

This is the tool used to pump the water-based solution in the ground loop to the unit inside the house or building. The flow center is placed on the geothermal unit or a wall nearby.

The heat pump is kept inside of the building. It is responsible for heating and cooling the entire building by forced air and radiant.
