A geothermal system provides heating, cooling, and often hot water using the steady temperature of the ground. It replaces a furnace, air conditioner, and sometimes a water heater—using far less energy.

No. Your thermostat controls the system just like a standard heating and cooling setup. The geothermal equipment automatically adjusts to keep your home comfortable.

Very little. The ground loop typically lasts 50+ years and requires no maintenance. The indoor heat pump may need a simple annual check-up but requires fewer repairs than traditional HVAC systems.

Usually, yes. Geothermal systems are extremely efficient, often lowering heating and cooling costs. Homeowners can expect stable, predictable energy bills throughout the year.

Geothermal systems place all major equipment indoors, so there’s no noisy outdoor compressor. This improves curb appeal, reduces wear and tear, and keeps the system quieter and more reliable.

Use the thermostat as you would in any home. Because geothermal works best with steady temperature settings, many homeowners prefer to avoid large temperature swings throughout the day.

Yes. The system relies on the stable temperature underground, not the outdoor air, allowing it to perform reliably even in extreme weather conditions.

Geothermal systems require electricity to run. If your home has a backup generator or battery system, the heat pump can operate during outages.

Yes. With no combustion, flames, or carbon monoxide risk, geothermal is one of the safest heating and cooling systems available.

The ground loop is a network of durable underground pipes that exchange heat with the earth. It’s buried beneath your property and is designed to last for decades.

Generally, no. You can landscape normally above the loop field. Avoid deep digging or planting large trees directly over borehole locations.

Many buyers view geothermal as a premium feature thanks to lower operating costs, low maintenance, and clean operation. Homes with geothermal often have increased resale appeal.

The system should operate quietly and maintain steady temperatures. If you notice unusual noises, uneven temperatures, or rising energy use, a technician can evaluate performance.

Your home should include documentation identifying the installer or maintenance provider. EarthWorks and its partners can offer long-term service, maintenance, and system checks.

Yes. Geothermal produces no on-site emissions and uses far less energy than conventional HVAC systems, significantly reducing your home’s environmental footprint.
