Hello, I recently had a new A/C compressor installed. On the inside of my house where I guess the evaporator coil is, leaks water into the flor and is causing problems. Is this normal? What needs to be done to correct he problem? There is a drain line attatched to the unit. Could tat be stopped up? I would appreciate any comments or suggestion anyone may have.

Thank You

 

I am not an expert but generally there is a steel pan under the evaporator which catches the water. The pan then drains outside through a tupe. If yous is in the attic it probably goes out to the roof and down a gutter. Sometimes the drain gets clogged as your mentioned and sometimes the pan rusts through and it leaks.

 

could also be caused by rusted out pan.more than likely it is the drain however, as the new a/c is probably producing more condensation.

 

Yep, if your ID evap is 12-15 years old , there is a good chance the drain pan under the coil could be rusted out. Look real hard with a flashlite. Most likely tho its a plugged up drain line and/or trap. Ideally it will need to be blown out with pressure or washed out with a garden hose. The latter willmake one big mess. You could remove the drain line onn the outside of the unit, blow it or flush it out and replace same. Still a mess but a cure. Some drains will be easy and short, others will be long with maybe a double trap. Theres another way but I don't recomend everyone try it. If you have some common sense and good judgement, this will do it. Go to the drain outlet with the garden hose. Turn the water on wide open. Take the hose end and butt it up to the drain end for just a second or two, depending on the length of the drain line. Use judgement here. Do this a couple times till the gook comes out and the water clears. Thats it, you're done. Depending on the length of the line, you may have to leave the hose on a second or two longer...maybe less. As I said, this isn't for everybody. I've done litteraly hundreds and recall only ONE that I goofed, big time, and I've never forgotten it. If you aren't sure of yourself, don't.
