How efficient is geothermal HVAC?

Geothermal HVAC systems are highly efficient and cost-effective. They use the natural heat of the earth to heat and cool buildings, reducing energy consumption by up to 70%. Geothermal systems are also more reliable than traditional HVAC systems, as they are not affected by extreme weather conditions. Additionally, geothermal systems require less maintenance and have a longer lifespan than traditional systems. Overall, geothermal HVAC systems are an excellent choice for those looking for an energy-efficient and cost-effective solution.
