Geothermal Systems
Geothermal Heating and
Cooling systems use a
heat pump to transfer the
heat from or to  
the ground.  In the winter,
it uses the ground as a
heat source and pumps
heat from the ground.  In
the summer, it pumps
heat out of the house to
the ground.

Pros and Cons

Pros:  •Low Operating Cost – geothermal heat pump cost
tends to be lower than conventional heating systems by
anywhere from $400 to $1,400 per year. Despite spending
a little more initially, geothermal heating ends up paying
back in around five years.
•Environmental Impact – geothermal heat pumps cost less
and they have less of an effect on the environment. Open
loop systems reduce emissions by up to 40% while
making little environmental impact otherwise.
•Reliability – geothermal systems can last anywhere from
20 to 50 years. When located away from harsh elements,
the heat pumps themselves are known to last for much
more than 20 years.
There are often tax credits, up to 30% of the system's cost.

Cons:  Geothermal systems cost  significantly more than
electric heat pumps, ranging from $12,000  to $30,000.
Besides the disadvantages related to the cost of
geothermal installation, geothermal systems can also
require a large amount of space.
A geothermal heat pump is usually installed in the home's
interior, which may or may not be an issue depending on
the layout of the house. However, the trenches or
geothermal bore holes for the piping can require several
hundred feet of open space, and wells for geothermal loop
systems can also require special considerations.  
Landscaping may be required to repair property after
placement of loops.
Tax Rebates of up to 33% of geothermal system
costs are available thru 2016!
