Thinking Green


Long before it was popular to build a “Green Home”, Duff Builders has been partnering with J.K. Mechanical to lead the way in environmentally friendly comfort systems. Whether your top priority is the environment, or saving on utility costs, a WaterFurnace geothermal system by J.K. Mechanical is the best heating and cooling option for homeowners looking to build a new home.  The upfront costs for a new construction geothermal system are usually less than adding one to an existing home, and the initial outlay can be included in the monthly mortgage payment. The increases in mortgage costs are typically offset by the decreased operating costs of our geothermal systems — providing a net positive cash flow.

A geothermal heating and cooling system from J.K. Mechanical is one of the most efficient, energy-saving, environmentally-friendly choices you can make for your new home.  In fact, according to the Department of Energy and the EPA, geothermal systems are the most environmentally friendly way to heat and cool your home.

These systems emit no carbon dioxide, carbon monoxide or other greenhouse gasses, which are considered to be major contributors to environmental air pollution.

With a green home from Duff Builders and a geothermal system from J.K. Mechanical, you can take comfort in a better environment.
