I have a Carrier high-efficiency propane furnace in suburban DC. Is 50 degrees too low to set the thermostat during the day?

During the winter while at home we like it at 70 or 68 if we are dressed warm. No one is at home at least 8 hours during the week and sometimes all weekend.

    Tom,
    Check your owner's manual. If you set your thermostat below 55 degrees, you may void the warranty for some Carrier high-efficiency furnaces. (Low thermostat set points may damage the furnace.)

    For more information on this topic, see the section under the heading "A low thermostat setting may void your furnace warranty" in this article: All About Furnaces and Duct Systems.
