The most frequent indicators your geothermal system needs repair include reduced heating or cooling performance, unusual noises from the heat pump unit, higher than normal energy bills, and error codes or warning lights on the system controls. Because geothermal systems operate differently from conventional HVAC equipment, some issues can be easy to overlook until performance has already declined noticeably. Scheduling a professional geothermal inspection with Precision Air at the first sign of trouble will catch problems before they escalate.

The components most commonly requiring attention will be the heat pump’s refrigerant circuit, circulation pumps, expansion valves, and electrical controls. The ground loop itself is rarely the source of problems but can develop leaks in older installations. Regular geothermal system checks help identify wear in mechanical components early, when repairs are typically simpler and less costly.

Absolutely! Geothermal heat pumps use refrigerant in their indoor heat exchange cycle, and refrigerant loss is possible if a leak develops in the system. Low refrigerant levels will cause a noticeable drop in heating and cooling efficiency and should be addressed promptly by a licensed technician at Precision Air.

If your geothermal system stops heating or cooling, start by checking that your thermostat settings are correct and that the geothermal system’s circuit breaker hasn’t tripped. If everything appears normal but performance is still lacking, the issue likely lies within the heat pump components or the circulation system and will require a professional diagnosis from Precision Air.

Most common geothermal repairs involving electrical components, circulation pumps, or refrigerant issues can be resolved within a single service visit of two to four hours! Ground loop repairs or issues requiring specialty parts may take longer depending on parts availability and the complexity of the work involved. Your Precision Air geothermal technician will give you a clear assessment and timeline after the initial diagnosis.

In most cases, geothermal systems are worth repairing even as they age because the ground loop, the most significant part of the installation, has an exceptionally long service life. If the heat pump unit itself is approaching 20 years old and experiencing repeated failures, a heat pump replacement while retaining the existing ground loop is often the most cost-effective path forward.
