Question Water Under Furnace

It is about 90+ here today, and really humid. I shut the windows and turned on the AC this morning before I went to work at 7am. I went down to the basement about 7pm and found water all over the floor. It is apparently coming from the supply side of my furnace. My condensate pump is working!!!!

I have an older gas furnace with a retrofitted coil/condensing unit. I know the supply fan doesn't have enough static to cool my 2nd floor, but it does OK on the first floor of my home.

I just purchased the house....and I still see the previous owner on occation. He said the trick to the AC is to take the filter out and open every damper in the house. Based on some of the other threads I've read maybe I'll take the condensate pump trap off and make sure it isn't plugged. There is a 1/2" clear plastic drain tube that goes up approx 4 feet than runs about 15 feet to my wash tub. I'll make sure that is clear also.

Any other suggestions....I'm all ears!

Is it OK for me to run it....the water isn't hurting anything in my basement.

Sounds like a clogged drain somewhere along the line. Make sure that the condensate line is clear and that all of the traps of filters, if there are any, in the condensate line are clear. No matter how much condensate the unit produces, if the condensate drain and pump are working right, they should be able to carry it all out of the house. As for leaving it run, as long as the water isn't bothering you I wouldn't think it would hurt the unit. Unless, it's backing up into the air handler and being picked up by the fan. This could cause problems inside of the air handler. If it's just getting on the floor of the basement it seems safe to run.
