Yesterday was an extremely hot day here in SoCal with temperatures around 100F. The AC unit had been turned off during the daytime and at nighttime we turned it on to cool down the house.
A few hours later I noticed water dripping down from the soffit right above the upstairs bedroom window on the front side of the house (two story apartment). I don't remember seeing that happen before so I took a closer look and pointed a flashlight at the window where the water was coming from. I noticed a little pvc pipe sticking out of the soffit and that's where the water was dripping out of.
I did some Googling and found some info saying that it could be the secondary or emergency drain of the AC unit, which is where the condensed water goes to when the main drain is clogged. It also said that it's usually in an obvious location so you notice when there's something wrong. I also saw some contrary info saying that it's normal for small amounts of water to come out but that seems to be quite subjective to me.
I turned off the AC after finding out about this, because I don't want any water damage inside of the house. This morning I turned it back on to see if more water will come out, but so far no water.
The actual AC unit is outside on the other side of the house in the back patio.
I've made an appointment with an HVAC company to check this out, but because of the heatwave HVAC companies are completely booked up and I'm going to have to wait for two weeks.
I'm posting here because I would like to find out if anyone can confirm that this is indeed the emergency drain and if it's still safe to use the AC without risking water damage. Could the dripping be caused by the extreme temperatures yesterday while the AC unit had been turned off during the daytime?
Two weeks with no AC is a long time with temperatures like this, so hopefully someone can give me some insight.
