Dwight, your system is very similiar with what we did (see other geo threads). Costs on target. I finally got a yearly anaylsis done and my savings (even with some initial problems that ocured) is running $3,800 a year so I still hope to recoup costs in 5 years.
Things that may help you along the way, is I ended up having them come back and put more 'spacers' between coils, my coils were more compact whereas yours are spaced maybe twice the length. They also added an extra coil, no costs, which is just a bonus for me. I am going with a new thermostat that tells me when my 'heat strips' do kick in. After much learning and watching my electric bills, which I did have an extremely high month (but come to find out so did everyone else in the area with geo). I have worked thru the issue and bottomline, is my total year came in below target so I am quite pleased. My geo continues to outperform my expectations. It is comfortable, barely notice it, I don't have the nose bleeds like bofore. I don't miss the high propane bills. Worthy investment. Keep us posted on your progress.
