    I don't like using always or never, but you could say manual j ALMOST always oversizes.

    4 tons on 1800 sf. Ooof. They don't mind the energy bills?
    Which makes more sense to you?
    CONSERVATION - turning your thermostat back and being uncomfortable. Maybe saving 5-10%
    ENERGY EFFICIENCY - leaving your thermostat where everyone is comfortable. Saving 30-70%

    DO THE NUMBERS! Step on a HOMESCALE.
    What is comfort? Well, it AIN'T just TEMPERATURE!

    Energy Obese? An audit is the next step - go to BPI.org, or RESNET, and find an auditor near you.

    Cool the house off at night and the thermal storage can carry it though a lot of the day.
