Geothermal Heating & Cooling Systems Repair Cost
The total cost of repairs to a geothermal system can vary significantly, depending on the extent of the problem, the type of repairs needed and your geographic location. When hiring a professional to do the job, most homeowners spend anywhere from $198 to $968 to fix a malfunctioning system. Costs generally average around $573.
Do I Need Geothermal Heating Repairs?
Even if it's still functioning, the geothermal heating unit might give some indications that it needs repairs. Watch for these signs so you can address the repairs before they cause a bigger problem to the whole system:
- Uneven cooling or heating throughout the house
- Unusual sounds like grinding or banging
- Strange odors coming from the system
- Strange wet spots on the lawn (often due to a loop leak)
- Malfunctions within the heat pump itself, like ice on the coils or a drop in airflow
Although the geothermal unit doesn't rely on fossil fuels, the system's heat pump is electrically powered. If you suspect you might have a problem with the pump and you notice a large spike in your energy bill, it could be due to a malfunction. If you notice any of these problems, it's best to call an HVAC professional who can assess your unit.
Geothermal Heating & Cooling System Repairs
The pipe loops buried underground are some of the most common things to malfunction in a geothermal heating system. These loops are responsible for carrying a water and antifreeze solution throughout the entire system. While the loops are built to last for many years, occasionally one will crack or break, causing a leak. A professional can place dye within the heat pump to identify the location of the leak and then fix the problem; the cost is usually between $75 and $100.
Like other types of heat pumps, it's also common for debris to build up within the system's pipes. An acid-scaling procedure flushes the system with acid, removing the debris and buildup as it's forced through the system. This usually costs between $150 and $200.
Finally, while it uses renewable energy, the geothermal system does have a variety of electric parts and components that help it operate, including the heat pump, blower motor and fan blades. Like other electronics, these parts can malfunction or wear out over time. Periodic maintenance may include replacing the motor, which might cost $300 to $500, or switching out the fan blades, which often costs under $50.
Benefits Of Repairing A Geothermal Heating System
A geothermal HVAC system doesn't need to burn fuel to work; instead, it simply moves existing heat from one spot to another. Because of this, it's an extremely cost-efficient system to operate. Using this system may save you up to 60% on your heating costs and 50% on your cooling costs.
In addition, the geothermal unit is a renewable source of energy, making it energy efficient and environmentally friendly. It doesn't use fossil fuels and emits no carbon monoxide. Plus, it provides even cooling and heating throughout the home and is much quieter than other systems, which means it's a comfortable, efficient option. While some homeowners might balk at the expense or inconvenience of repairing a broken geothermal unit, the benefits of this system often far outweigh the costs.
DIY Or Hire A Pro?
The geothermal unit is both intricate and expensive, and major repairs to the system are best done by a pro. If you suspect a problem with your system, don't go digging around your yard to try and fix the unit on your own; doing so could cause far more damage than good. Instead, look for reputable contractors who have experience dealing with these geothermal systems.
How The System Works
The geothermal HVAC unit takes advantage of stable temperatures underground to provide heating and cooling for your home. Because the earth is naturally insulating, temperatures underground don't fluctuate much. In fact, the earth's temperature remains relatively consistent throughout the year, no matter what the temperature above ground is.
The geothermal unit uses this consistent ground temperature as the exchange medium to transfer heat to or from the ground. To do this, it uses several components, including an indoor heat pump, a buried loop of pipes and/or a pump-to-reinjection well. The heat pump connects to the pipes, which are often installed in your yard four to six feet underground. Water is mixed with an antifreeze refrigerant and then pumped through the loop system.
In warm temperatures, the pipes take the heat away from your home. As it travels through the pipes underground, the heat radiates into the cool earth around it. A duct system within your home radiates the cooled air throughout the house. In winter, the geothermal system works in reverse. The pipes pull warm air from the surrounding ground. The air runs through the heat pump in your home, which compresses the air to a higher temperature. The resulting hot air runs through your house to heat it up.
