Preventative maintenence inspection on 2016 Waterfurnace 5 Series running in great condition. Fred's concern for high electricity bill/usage does not appear to come from the geothermal unit. Took some information on thermostat settings to review with office staff and Waterfurnace. Air filters are in clean condition. Air coil is clean. Test ran operation of first stage geo heat, second stage geo heat, aswell as auxiliary heating. Tested refrigerant pressures with aid tool. Nothing of concern was found or suspected. Blower motor and ground loop flow center pumps operating properly. No issues of high energy usage were found during inspection and no issues with the system were found or suspected. System is operating properly, efficiently and ready for Winter.
