Residential Installation Costs
The cost of an average three-ton geothermal system for a 2,000 square foot home is comparable to a traditional system. You'll also need to consider the added cost of installing the ground loop. This will vary on the type of loop chosen
But don't be discouraged: The extra costs can be justified in two ways:
Longer equipment life. The geothermal industry estimates the average life of a ground-source heat pump to be 20 years, compared to 10 years for an air-source heat pump or central air conditioner.
- Lower ownership and operating costs. For most homes, a geothermal system can pay back the difference installation costs in energy savings within three years; the whole system can be paid back in seven years! Over the life of the system, you could expect to save $20,000.
