Geothermal Systems
Geothermal HVAC systems are a sustainable option that taps into the Earth’s natural heat to regulate indoor temperatures. They work by circulating a fluid through underground pipes where the temperature is relatively constant year-round. Geothermal systems are highly efficient and can significantly lower heating and cooling costs over time, making them an appealing choice for environmentally-conscious homeowners.
