Everything you need to know about going geothermal

Developer

  • Geothermal systems are installed during early site work. EarthWorks coordinates with design teams and trades to integrate loop fields, mechanical equipment, and electrical connections without disrupting the construction schedule.

  • Not necessarily. With EarthWorks’ financing structure, the ground loop can be paid for over time, allowing builders to offer geothermal without raising the upfront home price.

  • Most single-family homes require a borefield the size of a driveway or side yard. Larger developments can use shared loop fields or vertical bore arrays to optimize land use.

  • Loop installation typically requires 1–3 days per home. EarthWorks coordinates tightly with builders to avoid delays to framing, mechanical rough-in, or utility work.

  • Yes. Geothermal performs reliably because underground temperatures stay stable year-round, even during extreme cold.

  • Loop fields require virtually no maintenance and last 50+ years. Heat pumps require less upkeep than traditional systems and typically last longer.

  • Yes. Homeowners typically see much lower heating and cooling costs thanks to geothermal’s efficiency and lack of fuel consumption, plus incentives improve savings further.

  • Absolutely. Geothermal supports electrification, reduces emissions, and aligns with green building standards such as LEED, ENERGY STAR, and Zero-Carbon Ready.

  • EarthWorks’ financing options transfer easily to the new homeowner, ensuring predictable long-term costs and a smooth resale process.

  • Yes. Most new homes can use standard ducted HVAC. EarthWorks works with mechanical engineers to ensure proper airflow and integration.

  • Geothermal offers higher efficiency, lower peak electrical loads, reduced noise, and longer lifespan. It also avoids outdoor condensers that clutter yard space.

  • Yes. EarthWorks handles system design, drilling, installation, heat pump integration, commissioning, and lifetime service.

  • Depending on the region, homeowners or developers may qualify for federal tax credits, state rebates, and utility incentives. EarthWorks assists with securing all available programs.

  • Yes. Shared loop fields or district-scale geothermal systems can support dozens or hundreds of homes efficiently.

  • Geothermal eliminates outdoor compressors, resulting in quieter neighborhoods, more yard space, and cleaner architectural lines.
