View Full Version : Dripping From A-Coil

I've recently started getting a lot of dripping from the a-coil in my central a/c system. The configuration draws from the bottom, through the filter, then hits a-coil, then blower, etc... Looks like the drip pan is draining properly. Appears that moisture is dripping directly from the coil onto the filter, rather than running down to the drip pan.

Any thoughts on why this is happening & how to correct it?

Thanks!

Any ice or frost could be low on freon. Big copper line cold and wet, small line warm.You sure coil is clean check there first. On the intake side. Filter clean and new every 30 to 90 days

not seeing any ice or frost. Filter is new - changed every 30 days. Will have to check temp on freon lines.

Some condensation is normal, right? But is it not supposed to trickle down the fins into the pan? Could it possibly be a dirty coil? I can see up through it somewhat.

Thanks for your help!!

Ed,

Sorry - didn't read your post carefully enough. You said it could be a dirty coil. What's the best approach to take to cleaning it short of pulling it out and hosing it off? Shop Vac - air compressor blow gun?

Thanks again.

There are a lot of coil cleaners out there that work good a shop vac on the under side helps there is a coil comb you can use that helps some. With the air compressor ok BUT look out you dont bend any of the fins there with it --and it will. When done a 50/50 mix water and clorox to wash it down from the top side. yes the water should run down into the pan .Make sure pan is clean and dont have a leak in it also.
