Geothermal Resources & FAQ

A geothermal, or ground-source, heat pump system uses the relatively constant temperature of the ground (or a water source) to heat and cool a building. In winter, it pulls heat from the ground into the building; in summer, it moves heat from the building back into the ground. Because it's moving heat rather than generating it, it typically operates far more efficiently than conventional air-source HVAC equipment. Sizing and designing that system correctly is the focus of our planning and design review service.

A ground-source heat pump is the equipment at the center of a geothermal system. It exchanges heat with buried pipes (a ground loop) or a water source, rather than with the outside air the way a conventional heat pump does. When that equipment isn't performing as expected, our existing system evaluation service identifies why.

Conventional HVAC exchanges heat with outdoor air, so its efficiency swings with outdoor temperature extremes. Geothermal systems exchange heat with the ground or groundwater, which stays far more stable year-round, so the system typically runs more efficiently and predictably. Getting that stability right starts with design and plan review.

A closed-loop system circulates fluid through a sealed pipe loop buried in the ground or submerged in a pond or lake. An open-loop system draws water from a well or other source, exchanges heat with it, and discharges it back. The right choice depends on geology, water availability, and local regulations, which is exactly what our planning and design review service evaluates.

Ground-source heat pump equipment typically lasts on the order of two decades with proper maintenance, while a well-installed ground loop can last considerably longer, often cited at 50 years or more. An existing system evaluation can confirm where a specific system stands in that lifespan.

Properly designed and installed ground loops are typically rated for multiple decades of service; many manufacturers and installers cite 50-plus years as a reasonable expectation for a correctly executed closed-loop system, one reason installation and commissioning oversight matters.

Geothermal systems generally require less maintenance than conventional HVAC since the outdoor equipment (the loop) is buried and not exposed to weather. Routine maintenance still matters: filter changes, periodic checks of the indoor unit, water flow, and controls. When something is missed, troubleshooting and repair is usually how it surfaces.

Common causes include an undersized or improperly designed ground loop, air or debris in the loop, declining water flow, controls that aren't configured correctly, or equipment that was mismatched to the building's actual load. Identifying which of these applies is the core of our troubleshooting and repair work.

Yes. Commercial geothermal systems are common in offices, schools, healthcare facilities, and other large buildings, often using larger or multiple ground loops sized to the building's load, which is where planning and design review becomes critical.

In many cases, yes. Conversion feasibility depends on available land or drilling access for the ground loop, existing distribution systems, and budget, each of which is worth an independent system evaluation before committing.

Geothermal systems can contribute toward LEED credits related to energy performance, and are frequently part of high-performance building strategies. Specific credit eligibility depends on the current LEED rating system and project scope, which our design and plan review service accounts for.

Frequently seen issues include an undersized ground loop, poor grouting or backfill around loop piping, water-flow problems, controls that were never properly commissioned, and equipment installed without accounting for the building's actual heating and cooling load. Careful installation and commissioning oversight catches most of these before they become long-term problems.

A geothermal consultant provides independent, specialized expertise on ground-source heat pump systems: reviewing designs, troubleshooting underperforming systems, evaluating existing installations, and supporting the owners, engineers, and contractors already involved in a project. See our full range of consulting services.

Common triggers include a system underperforming its design, unexplained energy use, recurring equipment or loop problems, a major repair-versus-replace decision, or a new project where the design team wants geothermal-specific expertise before construction begins. Our troubleshooting and repair service addresses most of these.

Building owners, facility managers, mechanical contractors, engineers, architects, developers, general contractors, municipalities, schools and universities, and, for larger residential projects, homeowners. See which industries we work with.

Yes, troubleshooting and repair of underperforming or problem systems is one of the most common reasons clients reach out.

Yes. Design and plan review is a core service, particularly useful before construction begins or before a major repair decision is finalized.

Root-cause troubleshooting, separating equipment issues from loop-field issues, water-flow issues, and controls issues, is central to our troubleshooting and repair work.

Yes. Much of this work is collaborative, supporting the team already in place rather than replacing it, across every stage from design review to commissioning.

Yes, an independent existing system evaluation before a large repair or replacement decision is one of the most valuable times to bring in outside geothermal expertise.

Yes. The earlier a geothermal consultant is involved in planning and design, the more expensive mistakes can be avoided.

Helpful information includes the building or project type, whether the system is new or existing, any available design documents or equipment specs, and a brief description of the problem or goal.

As early as possible for new construction, ideally during feasibility and design. For an existing system, as soon as a performance problem or major decision comes up, our troubleshooting and repair service can help.
