How Does a Geothermal HVAC System Work?
A: A geothermal HVAC system uses the stable temperature beneath the Earth's surface to heat and cool your home. In heating mode, the system pulls heat from the ground into your home. In cooling mode, it transfers heat from your home back into the ground. This process is extremely energy-efficient because the Earth's temperature remains stable year-round.
- Ground loops: A series of underground pipes circulate water or refrigerant to absorb or release heat.
- Heat pump: A heat pump extracts or expels heat depending on whether you need heating or cooling.
- Air distribution: The conditioned air is then circulated through your home via ductwork.
Geothermal systems can save you significant money on your energy bills while reducing your carbon footprint.
