Should water flow or not?
A split system is a complex engineering design for air conditioning, in other words a type of air conditioner. It consists of two block parts: internal (evaporator), and external (compress-condensate unit).
This technique is capable of not only cooling the air during the heat, but also heating it in the cold, until the heating is connected. Moisture is an indicator of the proper functioning of HVAC equipment.
Principle of operation split systems based on the fact that freon or a newer version of it, passing through the evaporator, gives the room cold and absorbs heat. In the cool season, everything happens the other way around.
But there are still situations when a “drip” signals a malfunction in the equipment.
How to understand that a breakdown has occurred?
First you need to determine where the leak occurred.
There are three main locations.
- Directly from indoor unit.
- Separate drops or large splashes come through the blinds of the split system with air flows.
- Water flows along the wall on which the indoor unit is located in the room.
Having determined the location of the drop, you can decide how to deal with it.
To get started, do a quick check. You should check the condensate bath, if the leak started during the heat season, when the air conditioner has been working for a long time in cooling mode, then this is a completely normal situation. When the tank is full, water will overflow and a leak will form. To stop the flood, you just need to drain the water.
Inspection of the condensate tank during the heat should be done once every few days, since the equipment at this time works at the limit of possibilities, as well as before the onset of cold weather. If after this the drops do not stop, then, probably, a serious equipment failure has occurred.
The most likely causes of failure
Below we will consider the most common causes of breakdowns due to which the split system may “cry”.
Reason # 1 - clogged drainage system
Most often, the blockage of the drainage channel is to blame. Different debris is clogged in the drain pan of the indoor unit or in the hose, therefore, cleaning split systems, whose steps are described in our recommended article.
How can the hose be clogged? Caught insects - wasps, moths, flies. In addition, water collects in the drainage pipe in summer, making it an ideal place for insects.
Due to repair work on the external wall, putty, particles of building materials or coarse dust may get into the hole in the hose.
This situation is relevant if repairs are carried out in the apartment above yours. In this case, all the garbage will fly towards your air conditioner and clog it. Therefore, it is worth covering the external unit with film.
Reason # 2 - pump malfunction
When there is no way to remove condensate in the classical way to the street through a drainage pipe, models with a pump (pump) are installed.
Typical causes of leakage:
- The pump itself is defective or even out of order. In this case, you need to contact specialists for its repair or complete replacement. Please note that such parts should only be replaced on models of the same brand.
- Problems with the air exhaust pipe. It is bent, clogged, pinched, or depressurized. Any changes with the tube can be triggered by the influence of time, the choice of poor-quality materials, improper installation, etc.
- The float chamber (sensor) is clogged. He is near the pump. To solve the problem, you need to clean it. After that, dry, reinstall and test.
- Weak or inactive contact may be due to poor-quality assembly of the device or manufacturing defects. Contact a service center or a specialist.
- Emergency power off. Suddenly they turned off the light or the device did not turn off correctly. You need to wait until the intelligent system turns off and only then pull the plug out of the socket. The evaporator is still cold and condensation is dripping from it, and the pump continues to operate.
The pump requires a careful attitude, like any part that operates under voltage. Preinstall residual current device - RCDs, if there are frequent blackouts in your area.
Reason # 3 - icing of the drainage tube
In cold weather, the drainage tube freezes. This happens if the air conditioner is turned on at minus temperature outside the window, and the condensate, at the exit of the cabin, becomes ice and clogs it. Or because of the large difference between day and night temperatures: minus at night, and during the day - zero or plus.
Reason No. 4 - poor-quality installation
Unfortunately, not all installers can host installation of split systems correctly. Sometimes the consequence of such work is a floating air conditioner.
This may include many errors. The wrong angle of drilling and installation of the drainage tube was chosen, without taking gravity into account, which causes air congestion in the tube, which interfere with the normal flow of condensate.
The drainage pipe hall occurs because substandard materials were used or work was done in a hurry. For example, instead of special drainage tubes, electro-horns are placed, which crumble after a few months.
Unprofessional work near the indoor air conditioning unit inside the apartment. For example, when you need to lower the ceiling. During the repair period, not many will want to allocate additional funds for the work of air conditioners. Therefore, inevitably there will be problems with the location of the system and the removal of condensate.
Due to poor-quality rolling, freon leaked and, as a result, the heat exchanger freezes.
The pipes that hold the freon tubes are loosely twisted and therefore the liquid drips onto the floor, but is not discharged. They should be tightened with a key, previously lubricated with a paste for sealing (sealant). In such a situation, the main thing is not to overdo it, otherwise you risk breaking the thread and damaging or completely breaking the part, and such repairs will certainly cost a pretty penny.
Unprofessional thermal insulation of a freon pipelinelocated under the indoor unit of the split system. A breakdown of this kind occurs due to the rush or inexperience of the craftsmen.
Reason number 5 - clogged filters
Filters ensure the cleanliness and freshness of chilled air, and also protect the system from contamination.
For high-quality cleansing, you can use the services of specialists or do it yourself. Knowing the main causes of a drop in a split system, you will choose the right method of dealing with it.
Options for solving the problem
As soon as you find that water has started to flow, immediately disconnect it from the power supply. You can clean the drain pipe yourself. To get started, take a medium-thick wire and make a small hook. Then carefully push it into the drainage tube and push it forward with rotational movements.
From time to time, take it out and clean it. If you feel that the wire abuts something, then the cause is a blockage. Thanks to the pre-formed hook, you can easily get any midge-bug. In addition, you should clean the condensate tank, bath, and filters from bacterial contaminants using special means.
If there is ice, then you should wait until the ice melts itself. Then he will turn to the master.After such express cleaning, a general one can also be carried out.
To do this, you need to disassemble the indoor unit. Using a screwdriver, remove the drain pan, then attach a high pressure washer (water hose) to the drain pipe and rinse for 5-10 minutes. If you find that the problem is in unprofessional installation, then it is worth calling specialists.
To prevent breakdowns, the air conditioner should be regularly cleaned, which consists of washing the filters and the drain pipe. In warm weather, climate equipment must be cleaned every 2 weeks. From time to time, the condensation level of the split system should be checked.
Now you know, if water has flowed from the split system into the apartment, you should immediately disconnect the device from the power supply. Then check the condition of the air conditioner. And if after all our recommendations, the water is still dripping, then immediately call the master.
Tips from experienced craftsmen
The most important thing is to keep the warranty card for the air conditioner, it will help to avoid misunderstandings arising during the warranty time. Order installation only from installers accredited by the manufacturer, and also follow the simple rules for operating split systems.
Before switching on, after a long break (especially after winter), clean the drain hose, rinse and dry the condensate tank. Open the top cover of the indoor unit of the air conditioner.
Wash the filter with a special antibacterial agent and dry it. Carefully inspect and wipe off dust from all visible parts of the machine.
Remember to carry out preventative cleanings as often as possible. If, nevertheless, the split system has flowed, then you should call a specialist for diagnostics.
