Water is dripping inside my furnace onto the floor.?

Question

My guess is that the humidifier may be leaking because I couldn't think of anything else. I checked it out and I don't see anything. I turn it off during the summer months. This just started happening so I don't know whats going on. Any ideas and/or remedies?

Answer 1

You probably have a flow thru Carrier brand of humidifier or a similar one made by Total Line.

Those have a flow across media in them and when calcium and/ or deposits build up the water flow does not reach the bottom drain pan, instead it flows over to the side and down to the furnace.

My suggestion is to remove the filter media and replace it or clean it in CLR cleaner which is available at Walmart.

Answer 2

Check out the tube that drains to the floor drain its the water that the system collects while the air conditioner is on.
It could be that. If the tube is blocked then it fills the pan and spills over onto the floor
Remove the hose from the "A" coil drain connection and clean it out with bleach water. Stick a small wire up into the tube coming off the furnace also to clean it out
This water usually has lots of bacteria in it so be somewhat careful

Clogged drain line, as a guess. If water can't get out it has to go somewhere. If you have one of those overflow tanks, they can fill up with sediment also causing problems.

Paid the furnace guys $80.00 to remove water from radiator blower bottom, it had filled with water, still had a do it yourself project to stop the condensation. Replaced drain line, some type of small diameter clear rubber hose; had slimed shut.

Over flow drain pipe from hot water heater can be another source.

That's my best guess, I have hot water heat using a radiator and blower to blow air through insulated duct pipes.

At work heat and air conditioning use same duct work, clogged drain line pretty much flooded the concrete floor clear to the sales area, had to cut out goose neck section in drain line and redo line. Totally electric system heat/air conditioning system with a few large ducts..

ac removes water ( humidity) from air when working, you have a catch pan w/ a drain. Thats stopped up, if white plastic pipe, cut w,saw close to ac unit 3 or 4" away,if no water comes out, stickpencil in drain of unit, have bucket ready to catch water, if other part of drain is stopped up, take outside and blow out w/garden hose or replace, when reconnecting,put tee fitting in line and pour hot water or bleach down perioticly to flush algae out

Answer 5

AC units will produce a lot of water. If the drain tube is loose or filled up with dirt, that may be where it is coming from. Are you running your AC any?

Answer 6

get some condensate drain pills from your local HVAC store like john stone or Granger
