Geothermal systems are the most energy-efficient HVAC option on the market—and BPM Heating, Cooling & Plumbing installs and services them for homeowners across Maryland.
Using the earth’s stable underground temperature, geothermal heat pumps provide year-round comfort with lower energy bills, fewer emissions, and long system life. Whether you’re building a new home or upgrading an aging HVAC system, geothermal offers unmatched efficiency and reliability.
What Is a Geothermal Heat Pump?
Unlike traditional HVAC systems that exchange heat with the air, geothermal heat pumps transfer heat to and from the ground. A series of buried pipes, called a ground loop, circulates fluid to absorb or release heat depending on the season.
- In winter: The system draws warmth from the earth and transfers it indoors.
- In summer: It pulls heat from your home and transfers it into the cooler ground.
This ground-source exchange is far more stable and efficient than air-source heating and cooling—especially during extreme temperatures.
System Components
A typical geothermal HVAC system includes:
- Ground Loop: Horizontal or vertical piping buried underground
- Heat Pump Unit: Usually located inside the home, connected to the loop
- Ductwork or Hydronic Distribution: Delivers conditioned air or heated water throughout the home
- Desuperheater (optional): Captures excess heat to supplement water heating
Types of Ground Loop Systems
We install and maintain all types of loop configurations, based on your property:
- Closed-Loop Horizontal: Trenches are dug 4–6 feet deep; ideal for large yards
- Closed-Loop Vertical: Boreholes drilled 100–200 feet down; ideal for small lots
- Pond/Lake Loop: Uses a submerged coil if a nearby body of water is available
- Open-Loop: Uses well water (not common in our service area, but possible)
Our experts will assess your land, soil, and climate to design the best loop type for long-term performance.
Benefits of Geothermal Heating & Cooling
- Up to 70% energy savings compared to traditional systems
- Whisper-quiet operation with no outdoor condenser
- Low maintenance and minimal moving parts
- Lifespan of 25+ years for indoor unit and 50+ years for loop field
- Eligible for federal tax credits and local utility incentives
Geothermal heat pumps are especially well-suited for Maryland’s climate, offering year-round comfort without burning fossil fuels. They also typically require fewer repairs.
Geothermal Installation Requirements
Installing a geothermal system requires:
- Adequate yard space or drilling access for loop field
