Construction progresses well. I met with my HVAC contractor earlier this week to go over the work he'll be doing. I looked long and hard at sustainable and renewable heating and cooling which would have been supplied by geothermal heat pumps. Conservatively for the four zone system that we are installing the price would've been in the neighborhood of $100K . Even with the 30% tax credit the cost would've been a budget buster. I'm really suspect how this guy could do it for a net of $10K.
Our system is a hybrid, also known as dual fuel -- one that marries up high efficiency propane fired furnaces with air source heat pumps. The heat pumps are the primary source for cooling and heating, that is until the outside temperature dips below the optimal one for heating. At that point the furnaces will automatically kick it. Pretty cool or warm as the case may be. Four strategically located air handlers will ensure good distribution without taxing any one zone.
One trusted source considers "dual fuel to be state of the art in the heating and cooling world and a notch or two less efficient than that of current best available geothermal systems."
As you can see from the pictures the windows and doors are all in, the roof felt is down and the shingles are staged for roofing.
My next update will be at the end of the month. Stay tuned.

Tom, I was looking to do Geo-thermal and for my place which is 2100 SQ it would have been about 25k. I think they guy you talked to is nuts. Look around it's a really good system my brother-in-law has it and man it keeps the place cool and warm for pennies. Glad to see you are finally building that home you always talked about. can't wait for the invite some day to come down and kick a few back with ya.
