If air is somehow creeping into the system (which I doubt), that means you would have a fluid leak. Have you seen signs of that anywhere?
FYI, if you are pulling fluid trough the bleeder valves using a vacuum pump like a MityVac, you will almost always see bubbles from air creeping in between the hose and bleeder valve.
