Water on basement floor

There is water coming out of central air conditioning unit. It is on my basement floor. I notice when I took a look there was a build up of water and it is getting on my basement floor. I have a hose that lets out to the basement drain. There is still water on the floor.

The song "knock three times , on the ceiling if you need meeeee! This sounds like a slow drain or plugged drain line, just reverse the water flow with a water hose or preassure! (last if its an old system over 20 yrs old you could have a rusted drain pan. try introducing bleach into the system (clorox)!............Thank-you very much!

My Carrier Infinity system Model FE4A is leaking water from the bottom of the unit on to the basement floor. How do I stop the leak?


have your HVAC technician check the pressures in your unit...sounds like you may have low pressure. You should NOT be having any ice build up to melt off.

Our central AC has severe leaking ( condensation)...what to do ?


Every airconditioner will create condensation that needs to drain. Your condensation is not going where it is supposed to, probably because the drain is plugged. Find the cooling coils (they might be in the basement, but are probably in the attic) they will be right next to the fan. There will be a pan or tray under the coils and there will be some kind of small diameter pipe or hose that should go to a sewer inlet, or might possibly go outside. You might possibly have a small collecting tank with a pump that will be operated by a float switch. Lots of possiblities, but it is likely going to be obvious once you find the drain hose.
Good luck.

The dehumidifier is getting cold condensation on the top outside of the unit and no water in the bucket. Model BGD-510A. I cleaned the filter and the coils and still have this problem.


Kathryn, if you are operating it in a basement application, the problem is that air temperature at floor level, is colder than at shoulder level. Dehumidifiers struggle to work at temperatures between 40 & 65 degrees F (Unless they are Low Temp model designed for basement applications). And will ice up at times. Raising the unit up off the floor onto a sturdy table, counter top, etc that can handle the weight of the unit, plus a full bucket of water, will usually resolve the problem.

If it's not a basement application, try lowering the humidity extraction level to 35%. In you have an analog unit, turn the control knob to Maximum.

I hope this helps you and thanks for choosing FixYa.

I have a Ruud Model UBHC-17J11NFD in my basement. Water is coming from the bottom of unit and pooling onto the basement floor. What should I check first?


Hello, most likely you have a clogged condensate line, in order to clean it you will need a wet/ dry vac and attach it to the outlet of the line and the suction pressure should dislodge the clog. Also, if the unit uses a condensate pump make sure it is working, if its not it can cause water to pour out onto the floor.

Hi. Our dehumidifier is kept in the basement. It collected water for about three years. Now it runs but does not collect water. I cleaned the filter, took the water bin out and put it back in, but it...


Gweinstock1, there are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.If you unit does not have an
LED screen on the control panel, turn the manual control to Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
Dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder
level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

Hope this helps you to troubleshoot and solve the problem. Please let me know. Thanks.

Leaking central a/c unit


All central A/C units have a condensate drain line that comes from just under the evaporator in the Main air supply plenum.

You may have a blockage in that drain line and will have to remove the pipe to clear the obstruction. Try flushing the drain pipe with warm water until it flows easily from the top to the end.

You might have a gravity drain that goes into a floor drain or a french drain along the basement walls. The other typical drain installation is a condensate pump that the water drains into and when the float in the tank is lifted, a small pump turns on and pumps the water (condensate) out of the house either thru a drain hose thru the wall, or into a drain in the basement, etc.

Check the entire drain line and anything connected to it for any possible obstructions and/or blockage.

If you have any other questions once you take a look at your installation, just add a comment and I'll check back within a day to provide more info, based on your input.

I hope you found this very helpful and best regards!

Works well but


Yup, they eat energy.

An electric dehumidifier includes a refrigeration cycle that is very similar to a window AC units and refrigerators. They cool the air in the basement to condense and collect water and remove humidity, heat the air as a required consequence of the refrigeration cycle and dump it back to your basement.

Two sources of humidity in basements include warm outside air that naturally cools due to below grade earth contact and water passing from the ground though the floors and walls and evaporating into the basement. Dehumidifiers do most of the work in the summer when higher temperatures outside enable air to hold more water content.

In the winter, cooler outside air contains less moisture by weight eventhough it may be raining and the relative humidity in basement will be less because the air is warmed relative to the outside. The lower moisture content in the winter also absorbs the water passing through the walls and floor.

From an energy perspective, you may want the humidity set NOT below 50%. This will keep humidity below the level mold desires, but prevents the dehumidifier from doing more work and eating more energy than needed. A cheap battery powered temp/humidy meter left in your basement will help. Sources that include the "mold triangle" (temperature, water & food) often separate fact from expensive hype.

If the dehumidifier doesn't keep up, consider adding a moisture barrier to the basement walls and floors such as Dry-lock and floor paints to ****** moisture entry. Moisture barriers act very similar with water as insulation does with heat. They don't eliminate the need for a dehumidifier, but they reduce the work they do and energy they eat.
