I have been researching geothermal HVAC systems and I am consider this option on a property I recently purchased and am renovating and plan to stay in for a long time. The home currently has 4 systems and is around 7,000 square feet and 3 of those systems are due for replacement so it is good time to consider geothermal. The property includes a well on the site (I don't know the capacity), not far from the house, and it borders a 3 acre freshwater pond that is spring fed but is shallow. Our summers are very hot, last month averaged over 90 degrees and was the hottest on record. Our winters are cold because of humidity even if the temps don't drop below 20 very often. I have found a couple of local vendors that claim to install geothermal, but from the threads on here, it appears that proper system design and install is the key for this to work well out of the gate. Do any installers travel from nearby states, or is this exclusively locally sourced system? If anyone on here knows of an experienced and reputable installer in this area, feel free to share. I also understand that the federal credits for geothermal expire at the end of December, and I guess another question is, is there enough time to design and install a system between now and year end? (I have to think so). The one thing I don't want to do is take this on, have it not work well and regret it. I am in the process of getting proposals now and any feedback could be helpful. Thanks.
