These days, geothermal heating and cooling systems are gaining popularity across the United States and beyond. Homeowners and business owners alike have begun making the switch to geothermal heating and cooling as a way of saving money on energy bills.
Geothermal heating and cooling is unique in the sense that it works by using a ground source heat pump and cooling system as a means of transferring heat either to or from the ground. During the winter, the ground can be used as a source of heat whereas it's used as a place to displace heat during the summer.
Still, like any other heating or cooling system, geothermal systems can run into their share of maintenance problems over time.
Signs That Repairs Are Needed
There are a few warning signs that all geothermal heating system owners should be on the lookout for. Often times, these symptoms show up shortly before a major problem makes itself known.
One of the most telltale signs that there's a problem is when the system begins to cool zones in the home unevenly. Specifically, areas of the home may seem warmer or cooler than others with no real explanation. This can be a sign that there's a leaking loop in the system, or if this is noticed during the winter, there could be a problem with the heat pump itself.
Another thing to be on the lookout for is strange noises, especially grinding or banging sounds, or strange odors coming from the heat pump or cooling system itself. These may be indicators of a more serious problem, and the system may need an acid flush.
Common Types of Geothermal System Repair
One of the most commonly reported problems when it comes to geothermal heating and cooling systems is that of leaking loops. These loops are made of durable plastic and are responsible for carrying refrigerant through the system. Even though they're designed to last for decades, it's possible for them to crack or break on occasion. Fortunately, fixing a leaky loop is an easy task and usually costs between $75 and $100.
Over time, it's also possible for debris and scaling to build up along a geothermal system's pipes. This is most common in the heat pumps. When this occurs, it may be necessary to have an acid flushing service done, which will remove the buildup. In most cases, an acid scaling procedure can be done for $150 to $200, depending on the severity of the buildup.
Finally, there are a number of other common repairs that may need to be performed on a geothermal system's heat pump. These repairs could include replacing the blower motor on the pump, which usually costs about $300-$500, or even new fan blades, which can be replaced for less than $50. Regardless of the necessary repair, it's always best to leave it up to a professional who has specific experience working with geothermal heating and cooling systems.
