AIR CONDITIONER LEAKING WATER The air condtioner leaks water. - filler.gif Water is a byproduct of air conditioning and is drained off and removed.
There are two categories of problems if there water appears around your inside air conditioning equipment.

  1. If water appears and the system is not cooling, the cooling coil is probably frozen.

    A frozen coil is the result of a low refrigerant charge or not enough air flow. A professional is needed to correct the refrigerant charge. Most air flow problems are due to dirty filters, which the homeowner himself should know/learn how to replace.
  2. If water appears and the cooling system is working fine, there is most likely a problem with the condensate drain. The drain may be a gravity type which simply flows down hill and outside, in which case. it is clogged somewhere. A shop vac, applied to the outside end, might clear the problem. Or the condensate might drain into a nearby mounted pump. This pump runs when it is filled, but will over flow if it fails.

The evaporator coil is very cold, which causes water to condense on it's surface, like how water condenses on a cold soda can. The water runs to a drain pan at the bottom of the coil and then flows outside your home via a drain pipe. If water is leaking around your furnace, you very likely have a clogged drain pipe or cracked drain pan and should have it fixed immediately.

However, if you have a heat pump and you see water around the outdoor unit during the winter, this is normal.

Take care.

    Hi, these are other reasons for leakages from air conditioners.

    The three most common reasons for water leakage from heat pumps are
    dirty filters or heat exchanging coils, blocked drains, and a shortage
    of refrigerant. They are pretty simple to diagnose and repair.
    Turn off the power source to your air conditioner before trying any of
    the following!
    1. Dirty Filters and or Blocked Heat

    When the filters, or heat exchanging coil, are
    dirty or blocked, this causes a restriction in air flow. This in turn
    can then cause the temperature of the coil to drop. If the coil
    temperature drops below zero, moisture in the air that is condensating
    on the coil can freeze and form little ice flakes which are then blown
    out of your air conditioner, causing water leakage.
    Check the
    filters, and if they look dirty, give them a good clean with the
    hosepipe or shower head. Remove all the dirt and give them a spray with a
    kitchen or bathroom antiseptic spray to kill any bacteria or mould on
    Check the aluminum coil behind the filters. If it is covered
    in dry lint, try vacuuming the coil carefully with the brush attachment
    on your vacuum cleaner. If it is particularly dirty, you will need to
    use a garden spray bottle and a strong grease removing kitchen cleaner.
    Spray it on the coil, allow to work for around 5 minutes then rinse the
    coil off with the spray bottle. This should remove the dirt and improve
    the air flow. Please be careful not to spray water near to the
    electrical panel on the air conditioner.
    ALWAYS read the
    manufacturers' manuals on how to clean your heat pump or air conditioner
    2. Blocked Drains
    On a wall
    mounted ductless air conditioner, a blocked drain can be pretty obvious
    and easy to diagnose. Water will usually drip down the wall from the
    back of the unit and may also leak through the air outlet at the front
    if the drain is blocked.
    Stand on a small ladder and look down
    from the top of the air conditioner. Towards the bottom of the heat
    exchanger is a little plastic tray which is designed to catch the
    condensate produced by the cooling mode of the air conditioner. Check
    that this tray is not full of water or overflowing.
    If your
    outdoor unit is directly behind the wall the indoor unit is mounted on,
    your drain pipe will likely follow the pipework through the wall and
    drip into the garden. If this is the case, find the end of the drain
    pipe outside, wipe the end clean with a cloth then blow as hard as you
    can into it. This should clear any blockages.
    If you cannot clear
    the blockage yourself, or if it is buried inside the wall, you will need
    to phone a professional HVAC service company and book a service call.
    Your Air Conditioner Has A Leak and Has Lost Refrigerant

    your air filters and heat exchanger are clean and you have lots of air
    flow, your air conditioner should deliver plenty of cool air. If it is
    struggling to cool the room for a few hours and then starts leaking
    water from the air vent it may be short on refrigerant.
    Set your
    heat pump to the lowest setting possible and leave it to run for a
    little while. Then check the heat exchanging coil underneath the
    filters. If it is covered in ice, your air conditioner has a leak and
    requires a professional to service it. If your air conditioner is
    leaking refrigerant, the leak will need to be found and fixed before it
    can have additional refrigerant added to it.
    If in doubt, or these
    tips don't work, contact your local air conditioning company for a

    Hope it helps.
    Take care.

My DeLonghi PAC A110L portable air conditioner is leaking water. How do I fix this?


If an Air Conditioner is on cooling then the Air Conditioner also removes humidity from the air any Split Unit, Window Wall A/C you name it... Any A/C on cooling dehumidify the air in the room.

To decrease the volume of the water:
1) Clean Air filter/s
2) Keep doors and windows close( can open now and again).

I don't know how that portable A/C of your look like but I believe theirs a water pan inside that needs cleaning I think it's full.( best is to service the hole A/C).

Hope this was useful.

Being that I am the owner of a Haier 12000 BTU portable A/C unit with the same flipping problem & having a husband that works as a refrigeration tech with plenty of experience with A/C units of all types, we have come to the conclusion that the evaporation pans they put into these portable units are either too small or faulty! The best advice I can offer you if you are out of warranty is to raise the unit onto a sturdy & level base (you can use wood planks if nothing else can be found) & attach a hose to the plug (open of course) & run the hose into a bucket. Sadly, I was unaware of how bad our situation was until my husband told me that it is "raining" in our dining room! We'll now have to rip up carpeting (only 5 years old), rip up the old vinyl flooring to check the sub floor & if that's too bad off, we'll have to replace it, then cut out the sheetrock of the ceiling, treat for black mold before it happens (because it will, wet wood & sheetrock make a lovely sort of place for it to grow exponentially!) then rebuild the ceiling! I hope you got help before my answer & good luck!

Walk in shower leak into room below

I would unscrew shower head pipe and either pipe dope it or tefilon the threads and then reinstall it. I would also take the handle(s) rosettes off and look for a leak from there with a flashlight, while shower is on. I believe the most comon leak for walk in showers are the door seals. Are you sure it is not coming out from under the door? Another test that yuo may want to preform is to Stopper the drain, fill the shower pan with water and watch for bubbles, or look for leaks from below.
