We had an existing closed loop geothermal heat pump system in place servicing the house, domestic hot water and pool water heating with a separate electrical furnace heating the pool room (indoor pool). We had a few people quote options for a replacement of our failing heat pump and electrical furnace. RGCV was the only one to suggest switching to an open loop (existing well) and then using the closed loop to heat the pool room which eliminates any electrical heating in the house. They were great to work with and the work was performed very professionally. The only issue I have is that they could have verified the flow rate on our well before the installation to make sure that the well pump was able to push enough water for the heat pump (it was not and we have to upgrade the well pump at additional cost this year). However the system works well and the price was reasonable for the service so I'm satisfied overall.
