  • I've had a ground source system since August 2006. My house has about 2000 sqft of climatized space. I have paid $75/mo for electricity on average over the past 16 months. That includes hvac, cooking, lights and hot water. My power company charges $0.046 per kwh which is very cheap. Our rates just went up this month. I should still be paying less than $100 on average. This system is the future. It's expensive at first but the payback is short with today's fuel prices.
