Unhappy Too much water under the Evaporator Unit


I've got a problem and I'd appreciate if anybody can suggest me a solution -
I have a central air unit and the evaporator is located in the attic. It was drippring too much water that fills the dripping pan underneath and overflows in the ceiling area.
I called one handy man and he said there is a leak in the coil. So far I know there should not be any water inside the coils and if it leaks - freon would come out - not water.
My question is - what might be the reason that i am getting so much water. How do I know there is problem in the coil. How much should it cost to replace it if needed. Why the waters were not draining out of the system or from the dripping pan etc.

Please suggest me what should I do and what should I check.

Water is normal...back in VA I would get 5 gal a day if it was real humid. Most likely you have a plugged drain for the pan.

You might be able to suck the blockage out with a shopvac from the outside..or low pressure compressed air from the inside. Do you know where the drain is located on the outside of the home?

The pan could be installed wrong..but if this is a new problem..its probably just a blockage.

Apparently yer handyman isn't real up on A/C.

I would say both the primary and secondary condensate lines are clogged. As stated, never hire a handyman for HVAC, if this is something you can't/don't want to do yourself hire a qualified HVAC tech. There may be underlying problems other then the drain.

So, what is the easy way to clean the primary and secondary clogged lines?

No easy way. You have to have the right tool to clean out the clogging pipes. (Either suck it out or compress it out). looks like both of your primary and secondary are clogged. call a tech if you never did this before, this may cost you $100-$200and after they clean the pipes for you, pour some bleach into the pipes every a few months to prevent it from happening again.
