Geothermal HVAC Equipment
Explore geothermal heat pumps and ground source HVAC equipment designed to use the relatively stable temperature of the earth or an appropriate water source for efficient year-round heating and cooling. Advanced Service Company LLC also provides professional geothermal installation, repair and replacement throughout North Alabama.
Understanding Geothermal HVAC Equipment
A geothermal system is more than the heat-pump cabinet. Correct performance depends on matching the equipment to the building, loop field, water flow, ductwork and operating conditions.
Water-to-Water Systems
Designed for compatible hydronic applications where energy is transferred between the geothermal loop and a water circuit.
Geothermal Flow Centers
Circulation components move loop fluid through qualifying closed-loop geothermal systems at the required flow rate.
Controls & Accessories
Thermostats, controls and compatible accessories help manage system operation and comfort.
Proper Geothermal Sizing & System Design
Geothermal equipment should not be selected by square footage alone. System performance depends on the building load and the heat-exchange capacity of the ground or water loop. Equipment selection should account for manufacturer application data and actual operating conditions.
- Heating & cooling load
- Entering water temperature
- Required loop flow rate
- Ground-loop capacity
- Ductwork & airflow
- Available static pressure
- Electrical requirements
- Auxiliary heat requirements
- Building envelope
- Site & loop conditions
Replacing existing geothermal equipment? The existing loop may be reusable in some applications, but its condition, design, flow and capacity should be evaluated before selecting replacement equipment.
Common Geothermal Loop Applications
The best loop configuration depends on available property, geology, water resources, local requirements and project design.
Horizontal Closed Loop
Buried piping installed horizontally where sufficient land and appropriate excavation conditions are available.
Vertical Closed Loop
Loop piping installed in drilled boreholes, often considered where available surface area is limited.
Pond or Lake Loop
A qualifying closed-loop heat exchanger may be placed in an appropriate body of water when site conditions permit.
Open-Loop Systems
Some applications use qualifying groundwater as the heat-exchange medium, subject to water quality, flow and applicable requirements.
Why Consider Geothermal Heating & Cooling?
When properly designed and installed, ground source systems can provide efficient, quiet and consistent comfort for qualifying homes and businesses.
High Efficiency
Ground source systems exchange heat with comparatively stable ground or water temperatures.
Heating & Cooling
A geothermal heat pump can provide both winter heating and summer cooling.
Quiet Comfort
Many installations avoid the conventional outdoor condenser fan associated with air-source central systems.
Indoor Equipment
Many geothermal heat-pump cabinets are installed in protected indoor mechanical spaces.
Existing Loop Potential
A suitable existing ground loop may sometimes be retained when geothermal equipment is replaced.
Consistent Operation
Ground-source heat exchange is less directly affected by rapid outdoor-air temperature swings.
Residential Solutions
Geothermal can be considered for qualifying new construction, replacements and major comfort upgrades.
Commercial Applications
Ground source HVAC can also serve qualifying commercial buildings when properly engineered and applied.
Replacing Existing Geothermal Equipment
If an existing geothermal heat pump is aging, experiencing repeated failures or no longer providing reliable comfort, replacing the equipment may restore performance while potentially retaining usable portions of the existing system.
Before recommending replacement equipment, important conditions can include loop configuration, entering and leaving water temperatures, flow, ductwork, electrical requirements, controls and the building's current heating and cooling load.

Geothermal HVAC Equipment FAQs
Helpful answers for researching ground source heat pumps and geothermal equipment.
Geothermal HVAC equipment uses a ground source heat pump and a water or water-and-antifreeze loop to exchange heat with the earth or an appropriate water source for heating and cooling.
Yes. An air-source heat pump exchanges heat with outdoor air, while a geothermal or ground source heat pump exchanges heat with the ground or an appropriate water source.
Yes. Ground source heat pumps can provide both heating and cooling when designed and installed for the application.
A typical system can include a geothermal heat pump, compressor, refrigerant-to-water heat exchanger, air coil, blower, controls, circulation pumps or flow center, and a ground or water loop.
Common designs include horizontal closed loops, vertical closed loops, pond or lake loops, and qualifying open-loop well systems. Site conditions determine which approaches may be practical.
Selection should consider the building heating and cooling loads, loop design, entering water temperatures, water flow, ductwork, electrical requirements, available land or water source, and manufacturer application data.
Proper load calculations are important for geothermal equipment selection and system design. Advanced Service Company LLC offers load-calculation services for qualifying projects.
Geothermal systems can provide high-efficiency heating and cooling because they exchange heat with relatively stable ground or water temperatures instead of relying only on outdoor air.
Many geothermal systems do not use the conventional outdoor air-source condenser found with standard central heat pumps. The ground or water loop serves as the heat exchange source or sink.
Many water-to-air geothermal systems can serve ducted buildings, but existing ductwork should be evaluated for airflow, capacity, leakage and compatibility with the selected equipment.
A water-to-air unit transfers energy between the ground-loop fluid and refrigerant, then heats or cools air that is distributed through ductwork.
Water-to-water equipment transfers energy to a hydronic water circuit and may be used in compatible radiant, fan-coil or other hydronic applications depending on system design.
Sometimes. The existing loop may be reusable if its design, condition, capacity, flow and compatibility are suitable for the replacement equipment. It should be evaluated before equipment selection.
