    Rheem Classic 90 plus 6yrs old short cycles not allowing humidity removal
    My furnace and AC doesn't seem to be running long enough to remove humidity and be efficient. Have a 1600 s.f. Ranch home with a full basement where the furnace is located. Is there an adjustment where it will run a minimum amount of time once its turns on? Thank you

    humidity in the living space can be an issue with the blower speed (indoor fan motor). If it was adjusted for the furnace (and I am a a/c and heat pump guy so please furnace specialists chime in) than possibly the blower is operating too fast. The slower the blower speed the longer (in A/C mode) the air is in contact with the coil and thus more moisture is removed. The blower probably has three speed taps so just to get you going that would be a place to look.

    This article is about static electricity and sounds a little about your situation in reverse.

    Good luck

    Hey thermalmedics. I agree, blower speeds could be the issue, or oversized a/c system which can actually add humidity to the home, making it feel "muggy".

    I didn't realize you are a heat pump tech, and thank god you are on AMHD, as we have needed a true heat pump guy for awhile (and by "awhile" I mean as long as Ive been around here.) You will fill a big void with your heatpump knowledge. Thanks for sharing.
