Hi all, Some months ago I built a house that uses geothermal heating and cooling. Here is some of the data: House size: ~20,000 square foot Location: Canton, MI Type: Closed Loop Configuration: Approximately 30 wells that feed 5 GeoMax 2 heat pumps (apparently Edison wouldn't let us use more commercial grade pumps). Radiant heat throughout the house along with 5 forced air units. The system does heating fine -- now. It was designed by Ferguson and I'm reasonably happy with the design -- though I have very little information on the design. The problem is the service and bugginess of the implementation has finally reached a point where I want to find a new contractor despite the fact I have to waive my service warranty to do it. Four Streams is the contractor the implemented it and it's been nothing but a cluster for us. At first, heating didn't work. Then heating did work but it was using the gas boiler backup for all the radiant heat. Then when that got fixed the forced air units didn't do heat. And now, surprise surprise, air conditioning doesn't work. I got word finally today that I have to switch the Geomax pumps from heating to cooling and to do that I have to physically open the 5 panels and move a wire connection. While I'm an EE by training, there's no way that's an acceptable configuration. In addition, whether anything is running or not, the main loop pumps run 24/7 (4KW) which kind of undoes a considerable amount of the point of having the system. There's nothing fundamentally wrong with the system. I just want to get a contractor who will work with me to implement some common sense features into the system (like say, at the very least, a simple switch to go from heating to cooling as well as have the loop pumps hooked to the PLC so that there's some intelligence in how they're running rather than simply being hooked up to an on/off switch). Plus, in general, ways of enhancing the system over time and maintaining it. I'm not as sensitive on price as I am to responsiveness. Is there anyone in the Canton MI area anyone would like to recommend? Thanks!
