Just wondering if anyone out there is having this problem My geo system was installed over this past summer It is a water furnace 5 ton unit with 3 250 ft wells. Not sure of the model as I am not at home. My home 1s about 2800 sq ft with a full basement not counted in the square footage. The original home was built in 1989 and the addition completed this fall. My Oct - Nov bill was $1,259.16 and my Dec- Jan bill is $1,951.17. These bills are up from around $300 for 2 months the previous year and time frame. I am about ready to give up and put in something else as I can't afford these high electric bills. A friend who works for the utility company said that my use of 13,737KWH for 2 months is more than what some commercial buildings use.
