    Central Air/ no condensation draining
    I normally have a steady flow of condensation when running my A/C, I have been running it for the first time this season for the last day or so and have noticed there is no condensation draining, also no "sweat" on the valve where they put in the refrigerant. Other then that the system is working perfectly although it does seem to be slightly humid in the house. Is it normal for there to be no condensation draining? Does it have something to do with the fact that the system has been off for the winter or is it a more serious problem.. Thank You

    Unless your house is bone dry there should be condensate. Check system for proper air flow (filter and registers all open). What have been your outside and inside temperatures been when running the A/C?

    Thanks for the response.. All registers open, excellent air flow, new filter, outside temp about 90, inside 70. The system is in a hot attic, could it be the condensation is drying up before it gets to the drain pipe exit? Is the drain from the pan at the lowest level in the pan or does the water need to reach a certain level before it will start to drain? I was thinking that because the pan was dry from being off for the season that it may take a few days before the fluid raises to the drain level. Is that a possibility? Thanks

    There should be a direct pipe to the outside with the drain pan being a secondary safety so the water will not flood into the ceiling if the main drain is plugs up.

    90 outside and 70 inside are good numbers. Equals a 20 degree difference.

    Run it for a few more days and see if the condensate shows up. Also if you have one check the indoor humidity. That will also indicate a possibility of what is going on.
