Service prior to fall out: All contractors were courteous and professional. Everything was installed in a timely manner. Even during the dispute they have been very professional. But after finally getting many months of direct energy-usage comparables to the previous year, the product they sold me is not nearly as efficient as I was lead to believe. This system which was billed as the most efficient heating cooling system (31 SEER) is only 11% more efficient (as measured by CEEBEE) than the 12 SEER system I had on the house to begin with. Trying to do a direct comparable between geothermal and in-air appears to be very difficult even though that is what was done in the initial sales discussions. When CEEBEE sells Air-to-air products they advertise significant savings when upgrading to more efficient products with higher SEER. In my previous house I had a 4 ton 21 SEER IQ system which saved me about $100/mo during the summer (original was a 10 SEER). CEEBEE sales person told me at the time of trying to decide between and IQ drive and geothermal that the IQ drive did not come in 5 ton...Westinghouse was advertising a 5 ton Westinghouse (FT4BG iQ Drive) at the time but a CEEBEE representative showed me an official listing and it is not on their but Westinghouse still advertises a 5 ton (Westinghouse did not response to inquiries). My biggest fault with the company is the contractors they use and I feel they totally oversold the product for the geological environment my house sits atop. I still need to ground truth this but conversations with another geothermal company with geology background indicate that the soil type (clay) may be preventing water flow across the loop causing poor efficiency. We also had a big issue with the company which transported the heavy equipment damaged the entrance of the community while entering and did not repair the damage. CEEBEE was not directly responsible for that but it just compounded the bad experience with geothermal. If I had to do it all over again, definitely would not go this route but now I am stuck with a very expensive product that is performing very poorly.
