Using Geothermal HVAC is Better for the Environment

Whether you’re building a new home in Lorton, VA, or replacing your existing home’s heating and cooling system, you’ll have a lot of options. Geothermal HVAC systems have been around since the 1940s, and they’re growing more popular as homeowners consider their environmental and financial advantages. Here are three ways using this energy-efficient equipment is better for the environment and your wallet.

Exchange Heat With the Earth

Just six feet below the soil surface, the Earth has a remarkably consistent temperature. All year long, the temperature averages a moderate 50 degrees Fahrenheit. Geothermal heat pumps take advantage of this consistency by using a ground heat exchanger. Instead of generating heat, they exchange it with the Earth. In the summertime, heat from your home is released into the soil. In the wintertime, heat from Earth’s interior is pumped into your home. Moving heat uses fewer fossil fuels compared to creating heat.

Use Two-Speed Compressor Technology

Most geothermal heat pumps use two-speed compressor technology. When the compressor operates at a lower speed, it uses less energy. The energy-efficient equipment automatically operates at the lower speed, only switching to a higher speed when a bigger temperature change is needed. The lower operating speed is quiet and reduces wear and tear on the system’s motor.

Save Energy With Variable-Speed Fans

According to the Department of Energy, about 42% of your utility costs are for heating and cooling. Energy-efficient geothermal HVAC systems significantly lower this with their variable-speed fans. A variable-speed fan blows air at a lower velocity for a longer period of time. This results in improved comfort and energy savings. When a bigger temperature change is needed, the system automatically increases the fan’s speed. These variable-speed fans last longer, averaging a 12- to 15-year lifespan compared to five to 10 years for single-speed fans.
