Pricing
The total cost for a 3-ton geothermal retrofit is typically in the $20,000 range. Applying the 30-percent Federal tax credit reduces the cost to $14,000. In some Maryland counties there are additional tax benefits www.energy.state.md.us/ of up to $3000, reducing the potential cost to $11,000. Depending on the HVAC system they replace, the payback period (in reduced utility costs) can be as short as 5 years.
