    It depends on how much heat gain/loss there is in the ductwork.
    There are no perfect duct systems.

    If you want to know that the equipment is doing, check at the equipment.
    If more government is the answer, then it's a really stupid question.

    That was my theory. Me and a few techs were basing our opinion or debating this and I said the guys on hvac talk will back this up.thanks.

    An attic install will lose a couple degrees. Crawl space not so much

    Best taken at the unit. So you know what the equipment is doing. No way to know if the air in the duct is picking up temp by the time it reaches the register, unless you checked it at the unit anyway.

    @ equipment=equipment performance

    @registers=system performance

    as was stated previously, if you don't know how the equipment, you'll never know how the system is doing
    It`s better to be silent and thought the fool; than speak and remove all doubt.
