A geothermal system is one of the most energy-efficient and environmentally friendly ways to heat and cool your home. Unlike traditional HVAC systems, which rely on fossil fuels, geothermal systems use the earth’s stable temperature to regulate your indoor climate. With such an efficient system, it’s easy to assume that it can run smoothly without much attention. However, regular maintenance is crucial to ensuring that your geothermal system operates efficiently and lasts for many years.
