A geothermal HVAC system takes advantage of earth’s constant temperatures underground or underwater. The system has an indoor air handling unit and a network of water-filled pipes called an earth loop. The system works like a heat pump, absorbing heat from the ground in winter and cooling your home in summer. Discover how geothermal heating and cooling systems can offer Deerfield, Illinois, homeowners utility bill savings, reliable operation, better indoor air quality, and flexible functions. 

Low Utility Bills

Since geothermal HVAC systems transfer heat instead of producing it, they don’t need much electricity. The pipes in most geothermal systems keep recycling the same water, so your water bill won’t increase. For some homes, the pipes may be in a lake, well, or pond instead of underground. Since the temperature of deep water stays constant, a pump takes water from the water source on the property, moves it through the system, and then returns the used liquid to the water source.

The energy you save will eventually pay for your geothermal system’s installation. The underground or underwater pipes make your hot water almost free, and federal tax credits can make geothermal energy more economical. These combined factors make a geothermal system a great investment, especially if you’re building a new home or replacing an old or inefficient HVAC system.


Geothermal systems have indoor pumps, fans, and compressors. Without eternal exposure and therefore damage from weather, they can last for up to 25 years, and breakdowns are rare. When you need to replace your geothermal unit, you can usually keep the more costly underground components in place. This feature makes replacing your geothermal system much less expensive.

The piping underground is polypropylene, the same material in municipal gas lines, and it can last for up to 100 years with minimal maintenance. Homeowners can also appreciate a lower risk of fire compared to a natural gas furnace or water heater.

Better Indoor Air Quality

Geothermal heating and cooling systems don’t cause contaminants like dirt, dust, and pollen to enter your home. The air handler also effectively keeps the air from becoming too humid, which prevents mold growth and makes your home seem cooler and more comfortable in summer.

Since geothermal systems don’t burn any fuel, you won’t have to worry about pollutants from combustion or carbon monoxide poisoning. All these advantages make reaching a high indoor air quality with a geothermal HVAC system easy, especially if you add an air cleaner or an air purifier.

Flexibility and Convenience

Geothermal systems need less room than conventional HVAC systems, so your heating and cooling equipment room won’t have to be as large. You can use the extra space for a larger closet, bedroom, or bathroom somewhere else in your home. Underground pipes replace the unattractive outdoor compressor or condenser in most conventional systems, giving you more space in your backyard as well.

Geothermal HVAC systems don’t make noise outside your home, and you’ll hear almost no noise inside your home either. You can also upgrade your geothermal heating and cooling system to heat your pool and the water in your home.

Additionally, you can have hydronic radiant floor heating installed. This type of heating heats your floor and controls temperatures with hot water that flows through loops of tubing connected to your geothermal system.

Adding hydronic radiant floor heating throughout your home will keep you from stepping on a cold floor when you get out of bed or out of the shower. This system will also help to effectively regulate indoor temperatures. Each room can have its own thermostat, so you and your family can control different rooms or zones independently. A hydronic heating system is usually supplemental, but some homes use it as the only heat source.
