Quick question.

Is is ok for water to be dripping from the evaporator coil to the a/c
drip pan?

I have 2 A/C units in my house and one now has water in the drip pan
that flows through an over flow pipe through the facia on my house.
The other A/C unit never does this.

I have lived in the house for two years and have never seen this
before. Should I be concerned? Is something wrong?

The filters are new.
