By tapping into renewable energy, geothermal heat pumps eliminate the combustion process and the associated threat to both your family and the environment.  There’s no fire hazard, no fumes, carbon monoxide, carbon dioxide, or other greenhouse gas emissions.  Considered the most environmentally responsible form of heating/cooling by the Environmental Protection Agency, geothermal HVAC takes advantage of the free energy source found in your own backyard and typically pays for itself in under five years.
