    How a Geothermal HVAC System Works

    The mechanics of a geothermal HVAC system aren’t overly complex. The unit takes advantage of the cooler ambient ground temperature in the summer and warmer temperature in the winter. Once this HVAC system reaches a contrasting temperature, it can easily maintain a comfortable indoor temperature for you and your family, regardless of the season.

    If you’re interested in a geothermal HVAC system, you can expect installation in your yard or driveway. Since the geothermal HVAC system can be up to 600 feet deep underground, it reaches a level where the temperature stays approximately 55 degrees Fahrenheit all year.

    The key components of this HVAC system are the underground pipes and the liquid contained in them. This liquid eventually circulates to the geothermal heat pump, allowing the unit to control the interior temperature.

    Benefits of a Geothermal HVAC System

    Many homeowners dismiss the idea of a geothermal HVAC system because of the initial cost. However, these benefits more than offset the expense:


    • Environmentally friendly: Geothermal HVAC systems are eco-friendly, and you don’t have to worry about the risks of greenhouse gasses, such as carbon monoxide.
    • Energy savings: As energy costs continue to rise in southern Maryland, geothermal HVAC systems offer a viable savings alternative. Homeowners typically see a 30–70% decrease in their energy bills when switching to a geothermal system.
    • Durability: HVAC professionals will tell you that a conventional unit usually lasts 10–20 years. Geothermal systems, on the other hand, can last 25 years or longer with regular maintenance.
    • Less maintenance: Geothermal HVAC systems require significantly less maintenance than conventional systems, saving you time and money in the long run.
