A.C.E.S. 

As they say themselves; "A.C.E.S. was created to fulfill a need in the Rochester Area: A studied and experience-backed renewable energy installation company that focused on making innovative mechanical systems accessible to both residential homeowners and small businesses."

They lead the field in Geothermal and Solar for residential;

"A geothermal heat pump does not create heat through burning fuel, it transfers existing heat with a heat exchanger (loopfield) in your yard. In the Winter, heat energy is absorbed from your yard and is transfered to your home. In the Summer, heat energy is transferred from your home and dispersed in to the ground. Once the heat exchanger transfers the energy between your geothermal unit and the ground, a refrigeration cycle elevates the 50 degree underground temperatures to over 100 degrees to heat your home. In the Summer, the process is reversed to cool your home."
