Air conditioner leaks air conditioner indoor unit

What to do if air conditioner leaks in the apartment?

Drainage is clogged, can not cope with the diversion of liquid outside: getting into the drain pipe insects, which are attracted to the water coolness in the hot period. They remain there, settling inside the unit, preventing the condensate from flowing out properly;

  • Drain hose is clogged with debris, dirt, dust, pet hair, which get inside split-system together with drawn air stream. Over time, residual dirt accumulates inside the drain tube, condensing moisture collects in the sump and then pouring over the edge to the outside;
  • Bacterial contamination of the reservoir, the entire drainage. If the necessary maintenance is not properly performed, bacterial colonies, mold, fungus begin to multiply in the unit. Microorganisms are accumulated inside the system, the slime is formed, preventing the natural outflow. Besides that it is dangerous to health of tenants, there are negative external manifestations: unpleasant smell, water leaking from the conditioner;

Drainage nozzle is not positioned correctly when installing. The hose must be placed on a slope so that the moisture flows out by itself under the force of gravity. If placed horizontally, with bends, creases, etc.д., Condensate could not overcome obstacles and would accumulate in the sump.

  • The indoor unit is not installed strictly horizontally as it is required by the installation instruction. Result: Water leaks from the air conditioner into the room;
  • during installation the elements of the system that diverts water were damaged;
  • Poor quality flaring of copper pipes contributed to depressurization of the cooling circuit. Freon starts to come out and ice starts to form on evaporator. When the ice cover melts, it will create a volume of liquid that the split’s drain was not designed for.

Using the air conditioning equipment in the cold period of the year at low temperatures. If split-system is not adjusted on work in frosty weather, no winter set for heating is installed, the water in a drainage pipe outside will freeze. The ice plug will prevent the moisture from escaping to the outside.

The causes of water leakage from the inside unit

A common cause of leakage is a clogged drainage outlet located on the side of the case facing the building. As a rule, clogging occurs due to insects crawling into the outlet. Obstruction of the outflow of liquid, which causes its retrograde flow.

How to eliminate. By blowing through the drainpipe. Even a slight displacement of the block is enough to push the remaining jammed water out.

The air conditioner is designed with small passageways to allow fluid to drain from the front to the back. If the timing of cleaning is not right, the passages will gradually clog. Water which has not left the front will leak out of the housing.

How to eliminate. You can try gently cleaning the technical holes with a thin wire or a knitting needle. Do not overdo it, as this can cause even more damage. You can try to remove the blockage with a vacuum cleaner. If these measures did not help to solve the problem, you should call a master from the service center.

If the warm air stream gets on cooler of the conditioner, it causes the massive formation of condensate. In this case literally splashes of water fly from the conditioner.

How to eliminate. The defect of the case where the air penetrates inside should be carefully treated with an insulating material.

If there is a freon leakage, the evaporator of the indoor unit is covered with an ice crust. Such a problem is usually encountered when the equipment is switched to heating mode. This causes the abnormalities to intensify: the leakage gets worse, uncharacteristic noises occur, ice chips can appear in the air stream that is blowing out.

How to fix. The causes of freon leakage usually cannot be repaired independently! Cracks in the pipelines, violation of tightness of copper pipe expansion joints. Such defects require special skills and are usually repaired by service centers.

Appearance of the liquid leakage right after the air conditioner installation can be the evidence of the drainage pipe cracking.

How to fix it. The breakage could be caused by the careless actions of a master-installer, and in this case the replacement is done for free by the company that installed the equipment.

A less threatening violation that occurs during installation is an insufficient angle of the drainage tube, leading to stagnant fluid in it.

How to eliminate. A repairer is required, installing the drain pipe at a sufficient angle to completely drain the condensate.

What the law says?

So, the air conditioner of the neighbor from above makes the loud sounds while working, it drips, spoils the windows, the antenna and the life? And the once pleasant upstairs tenants refuse to compromise?

In this case, those affected have two options:

And the probability to win such case is quite high, because the court often appeals to the Decree of the State Construction Committee of September 27, 2003. N 170.

And it says that the installation of any equipment, as well as the attachment of advertising products on the facades of apartment buildings, should be made only after obtaining permission from the Managing Company.

Note: Installation of air conditioner is equated to the re-equipment of a residential building, because during its installation there is a drilling of the outer wall of the house.

Air conditioner “leaks” after several years of operation.

If the air conditioner which has served you faithfully for several years suddenly leaks. The reason is in the absence or inadequate maintenance.

  • The drain pipe is clogged. Dust, insect, etc. can accumulate in the hose.п. That will cause the water flow to drop or be cut off. There were cases when in search of water during the hot period a Juke crawled into the pipe and afterwards got stuck and blocked the whole drainage channel. The solution: the drainage duct must be cleaned.
  • Freon leakage. Pretty volatile refrigerant circulating through the freon line. Freon, which only needs a microcrack to escape from the refrigeration circuit. Normalized refrigerant leakage is 6-8% per year, even if the system is airtight. If the amount of freon in the system decreases, the evaporator of the indoor unit freezes. A semblance of frost is formed, in severe cases. a snow coat. In this case the condensate does not flow into the tray of the pallet, but drops directly on the louvers, from them into the room. When air conditioner is working, it often looks like “water spitting. When water cannot flow down into the tray, the drop under its own weight comes off the rib of heat exchanger, falls down and hits the fan of the inside unit, which throws it out. Solution: check conditioner on freon leakage and if it is needed. top up conditioner. This procedure requires certain knowledge, skills, and tools. Leave this work to professionals.

No water dripping from the air conditioner: troubleshooting

Choose the repair method according to the revealed defect that results in no water dripping from the air conditioner. If the hose in the upper part (adjacent to the tray) is clogged you need to disconnect it and carefully clean. You can do it with vacuum cleaner, car pump or plastic bottle. For very bad dirt you can use rope or special liquid for cleaning split-systems. After treatment with a cleaner or wire, be sure to blow out the tube.

If the clog is caused by insects, use a wire to remove the nest. This problem can be eliminated by blowing out with a pump, just as with a clogged upper part of the hose.

If the drainage system does not work because the filters are dirty, take out the clogged elements and wash them in a soapy solution. Filters can be installed only after drying. If the charcoal filter gets dirty, you will have to buy a new part. These products should not be washed or otherwise cleaned.

In cases where the problem is caused by the wrong slope of the pipeline or a broken hose, a simple repair will not help. You will have to re-lay the drainage, cut through the walls and carry out finishing work. That is why you should not trust the installation of the air conditioner to non-professionals. It is better to entrust this work to the masters of the service center, which will take into account the manufacturer’s recommendations, and further service the unit.

The fitters with two left hands

The problems with condensate drainage can begin soon after the installation of the conditioner. In 99% of cases this is due to unprofessional (in some cases drunken) installers.

The point is that the drainage tube must run downward all the way. Sometimes during the installation in a wall they make a hole, which is parallel to the ground or it is directed upwards in general. In this case by the law of gravitation moisture will not be able to go out and will be accumulated in the tray.

Determine the problem is not difficult. just look at the places of entry and exit of the drain from the wall.

There are two ways out: either to pierce a new hole or to hinge conditioner up. But the best thing is to call the installers. They have to fix their mistake.

If you are putting conditioner by yourself, it is necessary to arm yourself with a peorator and to choose. Naturally, it will be easier to punch a new hole. Its inlet should start at the same place as the old one, but the channel should be directed downward.


Some errors are indicated by the indicators on the electronic display of the unit. Most often with these failures, the system turns on for a few seconds and then shuts off immediately.

There are the following main reasons for what is happening:

In any situation, the problem is easily solved by replacing the part that has failed.

The impeller is changed in the following sequence:

  • Removing the front protective grill.
  • Unscrewing the nut on which the fan is attached.
  • Motor pulley is released from the impeller.
  • Using a new impeller on the pulley.
  • The reverse order is used when reassembling parts.

The fan motor requires a few simple steps when replacing, too:

  • De-energizing the system, removing the front guard.
  • Unscrew and remove the nut fixing the whole fan.
  • Disconnecting all electrical connections.
  • Unscrew motor itself, disconnect completely.
  • Putting on a new part.
  • Assembling and fixing the parts, using the reverse order.

A certain order of actions is kept when replacing the starting condenser:

  • De-energizing the system.
  • Disassembly of outdoor unit.
  • Unscrewing the fixing clamp.
  • Disconnecting all wiring.
  • Replacing with a new starting capacitor.
  • Reassemble the parts, fix them in reverse order.

Fan repair procedure requires about an hour of free time. Urgency and scope of repair, the characteristics of the fan itself determine the total cost of work.

Water leaking from air conditioner

During the last decade more and more Houses, apartments and offices are receiving air conditioners. Users of air-conditioning equipment pay attention to water dripping from the device.

The technology of the air conditioner is based on the fact that the water is taken directly from the air. Condensation forming when the appliance is operating. moisture remains on the cold plates of the heat exchanger and drains into a special container.

So if the water is flowing from the outside of the drain pipe. it is a normal functioning of air conditioner. In humid climate in hot weather, the air conditioner can produce up to 14 liters of water per day.

If there is no water dripping from the external unit, this is a signal that the machine is not working properly.

But sometimes in the course of using the appliance, owners are faced with the unpleasant phenomenon of water leaking from the indoor unit of the air conditioner. Let’s try to understand why the air conditioner leaks? And what to do if the air conditioner leaks?

Specialists warn that not all faults can be corrected by yourself, some causes of malfunction require a call to a service shop.

Common Causes of AC Water Leakage and Troubleshooting

Sometimes the reason why conditioner is leaking is the clogging of drain hole, which is in the back part of a conditioner. Clogging can be caused by insects, which got into the drain pipe in hot weather. If the holes are clogged, water is sure to back up.

Remedy: Normally it is enough to blow into the drain tube, and the blockage will move and come out under the pressure of the accumulated water in the gutter.

Often the reason why water leaks from the air conditioner is because it has not been cleaned for a long time. The thing is that inside the appliance there are small passages that allow water to flow from the front to the back. If they gradually get clogged and blocked, the water collecting in the front will flow out to the floor.

Remedy: Use a toothpick or wire to clean the drain holes. You can also insert the drain tube of the air conditioner into the hose of a household vacuum cleaner, turn on the mode of operation of the vacuum cleaner. Dirty water must drain from the tube. If there is no access to the drain, there is only one way out. contact a technician to fix the problem.

Air leaking into the air conditioner may also be the cause of malfunction of the unit. Warm air flowing into the air conditioner gets on the cooler. excessive condensation is formed. In this case the air conditioner splashes with water.

Remedy: with the help of the insulating foam caulk the place of penetration of warm air.

Water leaks because of the freon leak, the result is freezing of the evaporator in the inside unit. This defect is characteristic for cold autumn days when operation of air conditioner changes from cooling to heating mode. The intensity of moisture leakage from the appliance becomes larger, extraneous noises may appear and even pieces of ice may fly out.

Elimination: invite a service technician or dismantle the air conditioner and give it to a repair shop. The thing is that freon can leak due to improper rolling of copper pipes and the formation of cracks in the bends of the pipes. Such a defect is not subject to fixing by yourself.

Sometimes there is water pouring out of the air conditioner right after its installation. This happens if there was damage to the drainage pipe during installation.

The fix: of course, this breakdown occurs through the fault of the master installing the device, so the replacement of the drainage pipe you should do for free.

Where to buy a replacement

While you are carrying out repairing works, the portable conditioner can be a temporary replacement of the stationary device. It can also be useful in the country, or, for example, when traveling somewhere to visit. Optimal, in terms of price-quality ratio, is the option of buying in the online store Aliexpress. Mandatory long waits for parcels from China are a thing of the past, because now many products are in intermediate warehouses in destination countries: for example, when ordering you can select the option “delivery from the Russian Federation:

If you saw a drop on the body of the inside unit of conditioner or a leak on the wall you are not obliged to run to the master. Carry out elementary cleaning of the tray, wash filters, check condition of a drainage tube. If the air conditioner is frostbitten. allow the ice deposits to melt, then wipe down the cabinet and run the unit in drying mode. After that you can use your split-system again.
