Row of Residential Homes


For environmentally conscious consumers, a geothermal heating system from leading Central Pennsylvania residential heating contractor Haller Enterprises offers maximum heating efficiency while utilizing renewable energy sources. Unlike traditional fossil fuels, renewable energy is safe for the environment and offers unlimited energy capabilities.

Harness the Energy of the Earth with a Geothermal Heat Pump

A geothermal heat pump from Haller Enterprises will heat your home efficiently while utilizing renewable energy resources. With a geothermal heat pump, a closed loop of pipes are inserted into the ground and filled with a solution that constantly circulates through the geothermal system in the home. Depending on the season, the solution is either heated or cooled by the earth as it travels through the pipe system. Because the solution is already around 50°F, less electricity is needed to heat or cool it, saving you money on your energy bills.

Not only will Haller provide fast and efficient installation of your geothermal heat pump, we also provide world-class service. Whether it's a routine "check-up" or a service call for a more complicated repair, we're never more than a phone call away.
