A/C drain line blockages
With the hot weather we are getting calls for water leaking from the inside air conditioning unit because of a plugged drain line.
Had a look at your unit lately?
Might want to check rooms and closets that share a common wall with the inside A/C unit, particularly if you don't go in there regularly.
The drain line is usually a white pvc pipe and is on the front(ish) area of the indoor unit. most have a small stem sticking up with a drain cap snugged onto it. The cap can be removed with out too much trouble.
SOMETIMES blowing on the open end of the pipe will dislodge what ever is causing the problem. Yes it sounds gross, but really it is clean water and a pipe with a little dust on it (which could be wiped off).
Most likely you will need an A/C technician.
While we aren't experts on unclogging the A/C drain line...we are experts on getting the water out of your home/building and getting things dried out.
