First of all thanks for the forums and any help/suggestions received. I am researching a Geothermal system for my 16 year old home, 1160 square feet, original 2-1/2 ton a/c, 15 KW strip heat, and electric water heater. I have had two contractors I have crossed off already, one had poor/lack of communication, the other didn't show up as scheduled and called the next day to set another appointment. So the quoting process is proceeding at a snails pace. I did have one contractor come out, when I called they said they have been running $4-5000 a ton. He arrives on time, measures duct work, windows, insulation and size of my home. We go outside and look at areas for vertical loops, we agree on two different areas, and agree to get input from driller. He stated one loop per ton drilling to 120 ft. I received his load calculations, it was run on Adtek Accuload 1.4.1. St. Louis, MO area Summer outdoor drybulb 95, indoor 75 Winter outdoor drybulb 0, indoor 70 Heating-24580 Btuh, Cooling-23238 Btuh He says he would be comfortable installing a 2 ton system, and that he was waiting on the driller to get back with him. A few days later I receive an email with my quote. Below is a copy and paste of the wording with the drilling company name removed. Remove and haul away old equipment. Install new Bryant 2 ton geothermal package unit with 12 KW back up heat and hot water generator. Reconnect to existing ductwork and electric. Install new digital programmable thermostat. Drill two wells in yard to be done by driller. Pipe existing hot water heater to hot water generator in new unit. Price includes all labor and material to complete job. The total came to 13,990, way above his statement of 4-5000 per ton, although it comes in that range with the tax credit, that was not mentioned when he stated the rough cost per ton. I am concerned with the lack of details on the unit and have requested additional information on the model I was quoted, single stage, two stage, etc. The 12 KW of backup heat seams strange as we discussed that I have backup already, although the strips are likely a small percentage of the cost. Sorry for the long first post. I plan on continuing this thread as more quotes arrive, any input is appreciated, Thanks.
