Humidity is in the low 60's and I'm not sure how to get it lower.
System is 5 years old, we bought the house the end of last summer and didn't notice the humidity problem (weren't checking for it either)
Funace is a Carrier 58WAV091-14 with a 3 ton coil.
Condensing unit is a 38BC03632.
Metering device is a .073 piston
DeltaT 13-18 degrees depending on outside tempature.
Suction line feels cool (not cold enough to sweat) to touch, liquid line is about the same temp as outside ambient.
Unit is oversized, runs about 1/2 the time on 100 degree day.
I've already tried lowering the blower speed and that did get it from the upper 60's to the lower 60's
I suspect the freon charge might be low but have no way to check it since I don't have a set of gauges.
Any ideas on the best way to get the humidity down?
Would adding a TXV be cost effective?
