Hello all,
We live in Georgia and have a Rheem A/C unit. I just read
about the need to have condensate drain cleaned out every year.
Thus far, we have never done this for the last 4 years in this
house.

Is once a year a good rule of thumb?
How does a person who is not hands-on type verify
if this needs to be done?

We have an attic where we go to change the A/C filters.
Then there are units outside the house. Should the drain
be checked outside the house?


Any help appreciated!
THANKS
