I have just built a new home in 2002. I installed a wetaher king heat pump and have had trouble ever since. I have had the technician out four times now becuase the heat pump will not quit running. Each time the technician either removes freon or adds it. My electric bill went from $150 during the summer to $400 during the winter. I am keeping the thermostat set at 67 degrees. I did insulate the home to the fullest and added upgraded energy efficient windows. Any help out there would be very appreciated.
