I speak with hundreds of people who are conscientiousness about the environment and they intuitively know that geothermal is a green energy - and basically agree that it is the cleanest heating and cooling method, but they don't really know what it will look like for them. You, too, may be wondering how is this geo-thing really going look and work for me? Will it really reduce my carbon footprint? We say - don't over complicate it! The simply fact is making the decision to go geothermal will absolutely reduce your carbon footprint.
This is an older home that we installed two geothermal heat pumps into about 2 1/2 years ago. It has a four ton unit for the main floor and a two ton split unit for the second. The install was challenging, but we're always up for a challenge. I've often heard geothermal doesn't work in older homes. This is simply untrue. New homes can have the best energy conservation practices incorporated into the building process while existing homes have a much more limited set a measures available to them. Upgrading windows, adding insulation to the walls or getting the shell of the house to the tightness achievable in new construction is either expensive or impossible.
The availability and price of energy is a huge concern for homeowners and businesses in our area. The first line of defense against price spikes or shortages is conservation and efficiency. If you need less, then you are less at risk. Geothermal heat pumps run at an average efficiency of 400%. This means 75% of the heat they provide is pulled from the ground. It is not subject to price fluctuations, and it will always be there. Geo systems run on electricity. Electricity is produced in many ways.
