A/C working, but not dehumidifying well
The condensation line on our a/c unit became plugged and the condensation went into the overflow pan, then outside the house. I cleaned the drain line and it is working again. But the humidity in the house has gone up to 70% during the day and 60% at night. The air coming out of the vents is cold.
Granted it has been horribly hot and humid outside (Houston)
but the unit has worked better than this in weather just as hot before the drain line plugged up.
The a/c unit is a Trane and was installed in 1994.
Any ideas what the problem could be?
