Hi Everyone, I'm brand new to this forum so I apologize, Geothermal is very new to me. I just purchased a two story zoned house 2650 square feet built in 1978. I live in central PA so temperatures can be drastic in both Summer and Winter. For Air-conditioning my second floor has its own (Carrier almost three years old) air handler and outside unit, same story for the first floor. However, when it comes to heating my house and hot water I unfortunately have oil! My heating is radiant hot water baseboards for the second floor. The first floor A/C unit has some kind of hot water coil inside it and that heats the first floor. Not a terrible set up but I do not want to pay the price of oil. Plus the 26 year old NewYorker is on its last leg I'm sure. Now onto Geothermal, I have had three different companies come out and give me quotes for Split systems due to my zoned house. The first companies quote: $38,402.00 Climatemaster Tranquility 30 series 5 Ton's- 3 ton unit for first floor(TEV038) two stage compressor and variable speed ECM motor. And a 2 ton unit for second floor (TES026) two stage compressor located in basement. One Climatemaster TAH026 2 ton air handler with variable speed blower located in the second floor attic. Two Flow centers built in the units Two auxiliary heat kits Two Bradford White 50 gal electric water heaters 3 vertical wells at 250ft. The second companies quote: 37,611.00 Climatemaster Tranquility 22 series 4 Ton's- 2 Ton unit for the first floor (TZV024) 2 stage variable speed package. And a 2 ton unit for the second floor (TES026) Split system in basement and a TAH 026 air handler in the attic. 1 Bradford white 50 gal electric water heater. Connecting De-superheater from first floor unit to my existing indirect tank. 2 Climatemaster digital thermostats 2 8kw Auxiliary heat kits 2 wells at 300ft. The third company quote: Have not received it yet, they came just yesterday. This company is going to quote me for a Carrier Geothermal system. According to their sales rep Carrier and Bosch are no longer connected at all whatsoever. I have read a lot of bad things when it comes to Bosch units. He assured me that within the last 6 years Carrier and Bosch are completely separate units. He went on to say that Carrier has a great performance series and an Infinity series that are great. He then said Carrier backs everything up with a 10 year parts and 10 year labor warranty! Plus Carrier offers a 60 month 0% interest loan, or a $1400 rebate for each unit so $2,800. The other companies have financing as well but either 1 year 0% or 97 months at 9.99%. (not so great). This Carrier option is starting to sound very appealing to me. Any insight or help would be very appreciated!
