Geothermal HVAC systems are becoming increasingly popular for homeowners in Monterey, TN, looking for a green and cost-effective way to heat and cool their homes. How exactly does a geothermal HVAC system work? Let us take a look.

How Does It Work?

Geothermal HVAC systems operate using Earth’s natural heat as an energy source. They work similarly to traditional air-source heating and cooling systems, but instead of only using electricity or gas to generate heat, they also use the earth’s natural warmth. A geothermal system consists of an indoor unit, an outdoor unit (known as a “ground loop”), and piping that connects the two units.

This piping contains a solution that circulates through the indoor and outdoor units, which helps transfer heat energy between the two components. In winter, this solution absorbs warmth from the ground outside and brings it inside to warm your home. During summer, it absorbs heat from your house before transferring it back into the ground outside.

A geothermal HVAC system is not to be confused with a geothermal power system, which utilizes steam from water reservoirs to produce electricity. When researching a geothermal system, it is important to know the difference between them.

Cost Savings

The biggest advantage of geothermal HVAC systems is their efficiency—they can save you a considerable amount of money on your heating and cooling bills compared to traditional air-source heating and cooling systems. This is due to their ability to utilize natural energy sources in addition to electricity.
Additionally, since these systems do not rely on outdoor air temperatures like traditional HVAC systems, they tend to be more reliable in extreme weather conditions. Therefore, you will not have to worry about your system failing during those sweltering Tennessee summers.


Since geothermal HVAC systems function differently than traditional air-source heating and cooling units—and require less maintenance overall—it is important to find an experienced technician who knows how to maintain them properly. Regular maintenance is important for keeping your system running efficiently and ensuring it lasts many years.

If you live in Monterey, TN, or nearby, consider investing in a geothermal system for your home today. Just make sure you find an experienced technician who can properly maintain it so that it runs optimally year after year.
