Checklist of concerns before a Ground Source Heat Pump 
is planned for your NEW home--

A Ground Source Heat Pump will heat and cool your planned new home with less energy and at lower cost than anything else can.  However, it will cost more in equipment and installation than a conventional system with a traditional fuel.  This cost premium you spend will pay back in time, and you should be concerned with how soon it can happen.  The equipment options you choose and your use of the federal tax credit of 30% will have a bearing on your cost recovery time (for the GSHP to return to you the extra costs beyond a conventional system).  Using a licensed contractor with certifications appropriate to HVAC and Ground Source installation is the smart way to go.

When you review the slides (below), you'll notice that most of the steps guide you toward an efficient building to begin with.  This will minimize the size of GSHP equipment you'll need.  It will lower your installation cost, and achieve a quicker return on the investment in this system.
Here is a slideshow featuring TEN items before pursuing a GSHP in your new home.  Click in the upper left of the blue box to play (or pause).  The automatic viewing time is set for 9 seconds and re-runs until you click to stop it.
