    If your unit is struggling to meet a set point, that means it is running a lot during this time. Run time equals consumption of electric. Getting your unit or envelope squared away so your unit meets the set point and cycles on and off, reduces run time which reduces consumption.

    A 15 SEER air source heat pump would use about 20% more electricity to cool your house than the SM060. The bigger savings with geo are in heating.

    Properly installed and with an adequate ground loop, your total electric usage for cooling should be about 5,000 kWh all summer, assuming your pumps are using 450w and assuming your stated cooling load is accurate.
