Geothermal HVAC systems offer Oklahoma homeowners remarkable efficiency by tapping into the earth's stable underground temperature instead of fighting extreme outdoor conditions. These systems can slash energy costs by up to 70% while providing consistent comfort, quiet operation, and exceptional durability with ground loops lasting 50+ years.

• Geothermal systems work by moving heat rather than creating it, delivering 5 units of heating/cooling for every 1 unit of electricity consumed
• Main components include underground loops (lasting 50+ years), indoor heat pump unit (15-25 year lifespan), and standard ductwork
• Initial costs range from $10,000-$30,000 but are offset by a 30% federal tax credit with no dollar limit through 2032
• Additional local incentives from Oklahoma utilities and electric cooperatives offer hundreds to over $1,000 per ton of capacity
• Installation options include horizontal loops (for larger properties), vertical loops (smaller lots), pond loops, or open loop systems
• Finding qualified installers with specific geothermal certification and experience is crucial for proper system sizing and installation
• The Database of State Incentives for Renewables and Efficiency (DSIRE) provides up-to-date information on available incentives

For comfort, savings, and sustainability, consider what it could mean to tap into the reliable energy resource right under your own backyard for your family's comfort and your home's future.
