Geothermal heat pumps are extremely energy efficient and typically do not use much electricity or energy. If you notice your monthly utility bills increasing with no other reasonable explanation, this is a very clear indication that your geothermal system is in need of repair.
Dirty filters are a very common source of geothermal power loss and failing efficiency. If your geothermal heat pump is not getting enough power, call (843) 466-6414 to have one of our certified technicians inspect your system.
Geothermal heating and cooling systems are generally a very quiet operation, so if you hear any type of loud noise coming from your heat pump, such as a rattling or banging noise, there is likely an internal issue with your system’s fan motor.
If your geothermal heat pump is older, it can produce wet patches along your yard where the loops are located underground. Fortunately, there are many methods that our team can use to detect and diagnose the issue in this situation.
Refrigerant leaks can cause frosting and ice to develop on the coils of your geothermal system. Consequently, this can cause a burning smell to occur from the ice and frost being melted and burned. If you notice a burning odor or frost building on the coils of your unit, schedule a geothermal repair immediately. This is an issue that requires immediate attention and can completely destroy your geothermal system if not dealt with in a timely manner!
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 Howell-Chase Heating and Air Conditioning 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 Howell-Chase Heating and Air Conditioning.
