I'm in the process of getting quotes for a geothermal system to replace my propane system. I got the first one today, here are the major details: Waterfurnace NDV049 4 ton unit, 10kW auxiliary heat Vertical closed loop - two shafts @320 ft per shaft Desuperheater with 50 gallon buffer and 50 gallon electric hot water heater Intellizone system for 3 zones New supply lines, new return line, use existing branches of of existing supply. All permits, grading, seeding, electrical, plumbing, etc. As far as I can tell it's a total installation. Removal of old equipment, etc. The cost for this is right around $35k before any credits. I'm in the process of procuring other estimates, but I'm curious if anybody has an early read on if this sounds reasonable. I did talk with another HVAC guy who loosely quoted me the following: $28k for Climatemaster 4-ton unit alone (no hot water or zoning) $32k for Tetco 4-ton unit alone (no hot water or zoning). I'm not going with this guy as I didn't like his "style." These quotes seem so high to me. Any thoughts are welcome.
