    I have a 2.5 ton condenser ,using regular manifold gauges
    I'm not purging the hoses,just taking high and low preasure readings only,is there a chance for air to get in this way ?

    I would think that the only way would be if you hooked up the low side with unit off then started unit when pressure drops it COULD pull in a little air
    But I have never had to worry about it because I always purge my hoses

    Why would you not purge them??
