Is a Geothermal Heating and Cooling Unit Worth the Cost?

If you are building a home or revamping your old heating and cooling unit, you could pay some attention to geothermal heating.

Geothermal heating and cooling systems tap renewable energy from the ground or earth. A good geothermal unit can serve you well for 20 years at least, and hardly needs any maintenance.


Energy efficiency

The Environmental Protection Agency (EPA) notes that geothermal energy units are energy-efficient and have very little carbon footprints. According to their sources, geothermal heating systems are 48 per cent more efficient than gas furnaces, and are 75 per cent more energy-efficient than furnaces that run on oil.


Costs involved

You cannot install a geothermal heating and cooling unit on your own, and would require the help of your San Diego professional. Prices of systems vary, but if your house in San Diego is 2,500 sq ft, with a heating and cooling burden of 60,000 (British Thermal Units) BTU each, the costs could be over $20,000. This is at least double the price of traditional heating and cooling systems, but savings on power bills in the future could be as high as 60 per cent. What’s more, you will gain from a tax credit of 30 per cent (federal) and many states including California have other incentives for installation of geothermal heating and cooling units.


The initial investment can be recovered in a time frame that ranges between two and ten years, depending on factors such as climatic conditions, funding options and the features of the system you opt for.
